This is my personal idea of how one can physically go back in time and witness events that happened millions of years ago. I have problems with the idea of folding space and traveling through a worm whole. This is a popular idea that scientists are toying with; but a critical analysis of that idea makes its feasibility improbable. Perhaps, it's due to my little knowledge that makes me think the idea of folding space does not hold any water. Any body who can really explain that theory is welcome to explain it to me. So far I haven’t had an explanation of the space-fold theory that makes sense to me.

Before I proceed with my idea, I most warn you that this idea does to propose returning somebody in the present to live in the past, change the past or manipulate the past. Actually I believe that is impossible. My idea only offers a feasible scientific way of how people in the present can watch the past, but not participate in it or change it.

Here I go:

We all know that the visibility of things depends on how much light they emit or reflect. I.e. you can see the light bulb because of the light rays that it emits, You can see your brother, your sister, your room, or any object because the light rays from the sun or other light source(electric bulbs perhaps) reflect off the object and goes into your eyes. Thus if something emits no light, or reflects no light, that thing cannot be seen.
Se we arrive at a well known conclusion: Visibility depends on light rays.

Now the light ray that is emited or reflected off things takes time to travel. Vision appear instantaneous to us because light(rays) travels extremely fast. It also follows that the further a thing is away from us, the longer it takes the light rays from it to reach us. Every body must have experienced this with sound. You can see a man sounding bell far away but the sound doest reach you the moment he strikes the gong, it takes a few moments. The same thing happens with thunder, which claps and it takes a few seconds for us to hear the clap; while the lightening that happened at the same time is seen by us almost instantaneously.

Looking at is critically, one can conclude that we can hear the past. Because the lightening that we hear may have already concluded before we hear the clap; the clap that we hear actually happened seconds ago. So this is a form of hearing the past. We can also experience the same with light; after all light( rays) and sound are nothing but waves which typically behave the same way. 

Lest just assume that the speed of light is 5 miles an hour. From an object that is 5 miles away from a light source, it will take an hour for light to travel from the source to that object. So if the light source goes out at 5pm; from this object, you can still see the light up till 6pm.
So when we look up to the stars in the sky, some of the stars that we see could have already died years ago; but from the earth we can still see them because the last ray of light that they emitted or reflected has not reached the earth.  So when we look up to the sky, to some extent we are actually seeing the past.

Now imagine the rays of light that the earth reflected 2000 years ago, from this ray we can see the earth the way it was 2000 years ago, irrespective of what the earth looks like now. The rays that light sources emit or objects reflect, travels perpetually away from the object or the light source. These rays will remain intact if they are not obstructed by another object. The rays that the earth reflected 2000 years ago are still traveling speedily away from the earth; so at a certain distance from the earth, one can see these rays. To put it simpler: If the speed of light is 5miles an hour; this means that the rays reflected by the earth 2000 years ago had only traveled 10000miles away from the earth. So if you look at the earth from another planet that is 10000 miles away from the earth, you will see the earth the way the earth was 2000 years ago.

Therein lies the time machine. If scientist can send satellites, with very powerful telescopic video cameras, so far away from the earth; and if from that distance, the satellites can video the earth and send the signals back to earth; then we can watch the past from the present time.

This means that from a TV screen or a computer screen we can watch what happened on earth 2000 or more years ago. 

Imagine watching the dinosaurs as they roamed the earth from your TV screen. Imagine watching the beatitude from your living room. Imagine listening to the actual Jesus on Sundays, during worship, from your TV screen. Imagine watching your favorite historic figures come alive again on your TV screen. Wonderful!!!!!

Anyway this is just an idea. But critically analyze it scientifically and tell me if it makes sense.

I know that the speed of light is actually 299,792,458 meters per second. I only said 5miles an hour just to make the math easier.

Okay, I'd like to be first to travel. How much is the ticket to see the Middle East about 6,005 years ago? Seriously, I need to get there and sort a few things out. . and see what colour all the races of our humanity had back then _{not that I don't like my own, though.}

Hehehe. . just kidding.

@vairo
You don't need a ticket, all you need is to subscribe to the "TIME TRAVEL Network"(A future network like Dish network, Direct TV and etc) Once you subscribe you will receive a satlite and a decoder box which you will hook up to your TV(Much like Dish Network and direct TV) Once you hook it up, you can tune in to any year you want to view. Your satelight will receive signals from a satelite in deep space far away enough from the earth to view the earth the way it was 6005 years ago.

Since the speed is light is 299,792,458 meters per second, and there are 31536000 seconds in a year; so the rays of light that reflected off the earth 6,005 years ago must have traveled 9454254955488000 meters away from the earth. So the satelite in space has to be positioned 9454254955488000 meters away from the earth for it to be able to record an event that happened on earth 6005 years ago. From that distance the earth will appear the way it was 6,005 years ago.

Of course, the TIME TRAVEL Network will be owned by me. I will charge subscribers only $ 50,000 a month. Ladies will only be charged $45,000 a month. And if you ever disagree with me on Nairaland, you will lose your subscription. LOL.

I believe some people have found the time machine in the west its quite a hidden technology the caucasians dont want to let out but there is a time machine. The west speaks to the world in parables through hollywood the hype on this time machine stuff is too much I believe they have the answer.

There's NOTHING hidden that wont be revealed. One we'll know how our ancestors looked like.

@justcool, your idea is quite intriguing but i think it can be fine tuned. Any light that reflected from the earth in the past will be spreading out at the speed of light (186,000ml/s). You are suggesting deploying a telescope that will intercept these rays and beam it back to us. What you fail to realize is that this telescope has to travel to the point X at which it wil start recording. The speed at which this telecope will travel from earth to point X is also limited by the speed of light.

Let me give you clearer decscription. If we were to deploy the telescope TODAY (assumming we have technology to transport at speed  of light) the telescope will be travelling side by side with rays that just reflected from the earth. Hence it cannot record any data older that TODAY. It even gets worse considering that this captued image wilL have to take an equalt length of time to reach us back on earth
What i am suggesting is designing a telscope or other device that can capture light (that was reflected from earth)  that has been bouncing around in space for millions of years. This telescope it to be resident on earth or near space and all it has to do is capure 'old rays' that reflected from earth and has been bouncing around for millions of years

time machine in your dreams, there're simply some things that are not possible

@The seeker: Brilliant! That was exactly what I was going to say when I read the OP. The argument is flawed on that one point. If it takes us 1 year to fly our history-decoder into outer space, then you can only start viewing history FROM that point, and not even 10 years ago let alone 6000 years.

@OP: Interesting idea. With some fine-tuning, you can use this idea for a sci-fi novel or suggest it to a movie director

enitan2002:

time machine in your dreams, there're simply some things that are not possible

The concept of time machiine does not necesarily mean a device that can physically transport you to another time. it may simply be a machine that can give you a glimpse of the past. Do you know that every time you look at the sun, you are looking 8.5 minutes back in time. if the sun were to dissapear suddenly it woiuld take you 8.5 minutes to visually confirm the event.

Brilliant post. But wait,
1.If it takes light 5,200 years to travel to point V in space. A "satellite" positioned at point V today can record things can immediately record 5,200 year old earth events quite alright but it will take another 5,200 years for it to send the signal to us us on earth. Reason. It is transmitting to us at the speed of light i.e speed of electromagnetic waves.
2. Electromagnetic waves (light inclusive travel in "straight lines". From point V it may not be possible to target the earth because other heavenly bodies will block the satellite's line-of-site.

They say that if you invent a time machine you can only go back to the point in time when it was invented due to the fact that you cannot travel faster than the speed of light.

When you think about it the time machine that captures real images of events from the past has already been invented. The camera does just that, and with the advent of high definition and 3d cameras we can already see real events that happened in the past on our tv screens. Its just a shame that scientists didnt figure out the properties of light and the electromagnetic wave thousands of years ago. Then we could have seen for definite what really happened at history's most important events. If only someone had the foresight to show the disciples for instance how to make a simple pinhole camera.

@ Justcool -

Nice one, but this idea is already in circulation.

Light contains pictures. The technology behind even the simplest camera confirms this. Accordingly the light from a star 1 billion light years away is actually light that is 1 billion years old. Indeed we may be seeing the star on earth long after it has dissolved or imploded, becuase we are seeing the version of the star (light from it) that was in existence 1 billion years ago.

Thus, each time you look into the night sky, you are already looking in many directions into the past.

For this reason what is needed is a machine that can decipher the images contained within light such that when we analyse the light from that 1 billion year old star, we can see pictures of all the events around that star that happened 1 billion years ago.

@OP: Interesting idea. With some fine-tuning, you can use this idea for a sci-fi novel or suggest it to a movie director

That reminds me there was a very good sci-fi book i enjoyed reading a couple years ago which explored that very subject by arthur c clarke and stephen baxter.
It's called 'The light of other Days' and you can find it on amazon. The religious implications when the true origins of the worlds religions were discovered was very intrigueing.
You can find it on amazon.
Amazon.co.uk Review
SF's grand old man Sir Arthur teams up with newer star Baxter to tackle a whopping science-fiction idea with ample scope for both their talents. Their "WormCam" video camera looks across any distance through tiny wormholes in space. Initially this seems no worse than a remote TV link, but it transforms the world as disquieting cans of worms are irrevocably opened. This gadget is a veritable WormCan.

Distance is no obstacle. Neither are walls. Early WormCams allow daringly invasive newspaper scoops--and once the general public can buy them, personal privacy vanishes forever. Anyone can spy on you anywhere. Or anywhen, because next-generation WormCams peer through time as well as space ,  at your embarrassing old secrets, at mysteries of the past, at the truth about old murders, Princess Di, the Mary Celeste, Abraham Lincoln, and even Jesus.

As WormCams steadily improve, they probe into deep time: spying on early man, walking with dinosaurs, back and back to a poignant SF vision of what came before life as we know it. It builds towards an utopian dream of the wonders humanity could achieve if given total access to its past.

Clarke and Baxter ramble intriguingly in all directions, exploring every implication. Their imaginative set-pieces are linked by a slightly soap-operatic plot featuring the megalomaniac entrepreneur whose labs built the WormCam, the sons he's manipulated like puppets, and one son's girlfriend who becomes a spanner in (as the lab's nicknamed) the WormWorks. Wide-ranging, ambitious and enjoyable.

@all
Thanks for your responses. I thought of all the things that you said, and I know my idea needs worlds of fine tuning. I only posted it as a food fro thought, and also for it to be compared with popular space folding theory.

The_seeker, ematan 2002,  validator, mantraa, and deepsight all made very scientifically correct observations. And know that my theory is not perfect and I have thought those thing that you said even before starting this thread.

But personally, I believe this idea makes more sense, and is more feasible than the space folding theory. What do you think?

@mavenbox,
I think you didn't get the idea. Reread my OP and you will get a better idea of what I am saying.

@ all
Thanks!

Please, I invite all the scientists in Nairaland to compare this idea with the idea of folding space.

@justcool: No i understood perfectly. I only said what the_seeker said in other words, and I was adding that we can not peer into the time BEFORE the machine was deployed, since the very instrument we are using would not exist at that "time" 

Howbeit my explanation may not have exactly come out as I intended, it is in concordance with these other posts

interesting idea.


Time travel may be possible if man could travel faster than the speed of light without disintegrating. Currently thats not feasible.


@justcool

you have some nice ideas about viewing the past, not necessarily travelling in the past.


but have you considered dark matter and dark holes which actually bend light time, slow it down and "freeze" it?

Thus if something emits no light, or reflects no light, that thing cannot be seen.

@mavenbox
No disrespect intended, but I think you still don't get yet. You can peer into the time BEFORE the machine was invented, if the machine is positioned at a distance far away enough from the earth to catch up with the light rays that reflected off the earth thousand of years ago.
Just as you can see a star in the night; from the earth you can see this star but the star may have actually died years ago. But you can still see it from the earth because the earth is so far away from the star, and it takes time for light that the star emitted to reach the earth. So the light that you are actually seeing is the light that the star emitted years ago. The star could even have died(no longer in existence) before you ware born, but you could still see it because the light rays that it emitted are still travelling to the earth.
Its much like sound. You can say someting, but the word you said may still be heard as it echos, even minutes after you have stopped talking.
Does it make more sense now?
Many thanks to you.

You completely got it!!! You are very correct. If only one can beat the speed of light, then the idea makes perfect sense and will completely work.
Because the major obstacle to the idea is that it will take a very long time to send the satelite to such far distances; and even if you succeed in sending it, it will take a very long time for the signal it transmits to reach the earth.

tpia.:

but have you considered dark matter and dark holes which actually bend light time, slow it down and "freeze" it?

Another brilliant observation! You are indeed a scientist! This is another major obstacle, and  I considered it. That's why I said:

justcool:

These rays will remain intact if they are not obstructed by another object. The rays that the earth reflected 2000 years ago are still traveling speedily away from the earth; so at a certain distance from the earth, one can see these rays. To put it simpler: If the speed of light is 5miles an hour; this means that the rays reflected by the earth 2000 years ago had only traveled 10000miles away from the earth. So if you look at the earth from another planet that is 10000 miles away from the earth, you will see the earth the way the earth was 2000 years ago.

Many thanks tpia

@justcool: Hmmm now I get what you mean Thanks for breaking it down
But really, justcool, i still think you can't peer into the past of the time machine, or rather the time machine's launch-time, unless

1. the device travels faster than light and thus beats the light to its vantage point of observation and/or
2. it travels slower than light, or as fast as light, and has a means of trapping light rays that have conveyed their information in the past and are still shooting across space

My reasons:

By wikipedia, some estimated durations of distances travelled by light are (http://en.wikipedia.org/wiki/Speed_of_light)
Earth to our Sun (8.3 minutes)
Earth to Alpha Centauri (4.4 years)
Earth to the other end of the Milky Way (100, 000 years)
Earth to the Andromeda Galaxy (2,500,000 years)

So, say we build our incredible history-recorder today, it is tuned up to travel as fast as light (if possible) and we launch it on January 1st, 2010.
After 8.3 minutes of launch, it is as far away as the Sun from the Earth. As such, it can trap all the light rays that ALSO left Earth 8.3 minutes ago, and afterwards. It can't even trap the light rays that left Earth 8 minutes ago (20 seconds before launchtime) because they would have travelled farther than the Sun, conveying the accurate information.

If we allow the recorder to continue travelling after the 8.3 minute distance, after 4.4 years, around the 24th of April of 2014, the history-recorder will have arrived at, say, Alpha Centauri. But the SAME light rays that it can capture are the ones that have travelled thus far from earth in 4.4 years. i.e. the very same ones carrying the earth's information at launchtime

If, however, we could travel say twice as fast as light, the recorder would be at Alpha Centauri in 2.2 years AT THE SAME TIME with normal light rays from earth that are arriving in 4.4 years (i.e. 2.2 years ago with respect to launchtime). even better would be the history-recorder travelling 10 times as fast as light, then we can view events that happened by trapping light rays released from earth 3.52 years ago because our device would be there in 0.44 years while the relatively slower light rays would arrive in 4.4 years.

On the other hand, if our device had a means of utilizing the light rays that left Earth millions (Olaadegbu and other YEC, that would be thousands ) of years ago and are now idly traversing outer space, and after receiving the information they carry, translating it without any error or appreciable loss of value; then the time it arrives in outer space is of no consequence. It may get there to Alpha Centauri in 4.4 years and still capture rays as old as 4000 B.C. and settle the YEC argument forever.

What do you think, Justcool?

What do you think, Justcool?

@mavenbox
I am happy that you finally got it. And I agree with what you said; what you said completely makes sense scientifically. Our device(Don't call it ours, its mine! ) will have to travel a lot faster than light for it to be able to record light rays that left the earth years ago.

And don't call the device ours, it's solely mine! Just kidding

Anyway, thanks for your contribution, it helped.

With your scientific knowledge, I have a question for you: Do you think this idea of ours(Mine) is better than the space-fold time travel theory? What do you think?

@justcool: Abeg o! me i no get scientific knowledge o, I just like analyzing information with scrutiny. It's fun, Carpe Diem.

Okay the device is yours, LOL. I wash my hands clean of any involvement with the machine: implied or otherwise!

I have very many unlearned opinions on this topic, however, seeing that I am only an engineer and not a rocket scientist . Maybe I will discuss them later, I pray I remember, AND have the time!

*spiffy yawn* Gotta sleep soon!

Really?!!!

I'll like to go back in time and never ask him about how to get on a Nigerian website

All you need do now is to build a machine with an einstein improbability drive linked via an array of flux capacitors to a stable casimir engine. With space and time being linked, just type in the exact coordinates in space and transpose the equation so that the distance travelled is in time and not space. You will be there in an instant. Simple.

One day when quantum mechanics, gravity waves and wormholes are fully understood it might be possible. Never say never.

The concept of capturing and recording the light of the present (which instantly becomes the past) was incomprehensible and considered impossible until very recently. Then we discovered the electromagnetic wave and photons and all the necessary equations etc.  Now we all take it for granted with miniature 'time machines' called video cameras on our mobile phones. Imagine if you could create a virtual camera by recording the reaction to light reflected off an atomic particle anywhere in space / time. It's probably just a matter of discovering the right equations.

Quantum mechanics can record a particle to be in two places at the same time. There is still a lot more to be discovered and understood.

Correct me if i am wrong but i thought the act of recording actually collapses the probabilty wave function and fixes the position of the particle at a single point

You are right. It's a very strange phenomenom.

Personally, I think it is nonsense. Because for you to see Africa for instance 6000 years ago, you would need to see the light rays of 6000 years ago in order to see the 6000 years ago africa. Much time would be needed and a tremendous amount of energy provided you are evn travelling at the speed of light. So my friend, the only possible way is to warp the rabric of space and time and cross into the FUTURE. not into the past. So imagine a 5 metre thread stretching from A to B. by bending the rope, point A can be stretched to point B i.e bending it into a circle and then releasing it into a straight line again.

I wonder what would happen in the Religion forum if your machine existed and suddenly we knew the past

Folding spacetime is a scientific kindergarten fantasy.

Trying to do light dependent recordings for such purpose just can't work. Light is too slow for the purpose you have in mind. How long will it take you to get your recording machine to the recording point? If you travel at the speed of light (which is impossible for you now) you will only just be on the sun in about 8 minutes.

I am not trying to discourage you.

Time and space[distance] is relative _{Albert Einstein}. Go figure
