How it WOULD be possible for us to see our past?

Answer 1

travel into the future is possible by einstein theory as one approaches the speed of light.

Traveling into the past is a different story though, access would have to be open from the past for this. There is no way to create a portal to the past, someone from the past would have to create the portal to the future where the future person could pass.

It is argued though that this would only open a door to another dimension and another universe independent of our own universe. If you think about it, the fact that someone could 'travel' to the past is direct evidence that other parallel universes exist. If you were to travel back into time history and events would inevitably be changed from occurences known to us in the present, therefore you must be in another universe.

Another way to see the past is to create a large gravitational force bending space time such as a blackhole, and align it so that the light traveling from where you are would be bent back to a location where you could observe it. This would be like viewing T.V. though, because you could have no interaction.

Answer 2

Time travel does not violate the laws of physics. Just got to bend the space time cuvature on to itself. It's possible. Better question is HOW PRACTICAL!!!!! Like, how do you get the curvature that way? With the immense speeds and forces taking effect, you would need a design **** with some pretty exotic materials and energy supplies. Another huge issue, how do you navigate such a journey. When you distort the curvature that much, the some laws of physics as we know it breaks down (e.g. blackholes), how do you know not where and when you will emerge if not a different universe? Even if you had a good idea, you probably at the mercy of time traveling. How do you do all that? It's a longs ways away.

Answer 3

Actually einstein says against this but people will never know until they try. First you somehow manage to travel faster than the speed of light. The reasoning for this is that einstein said that through the three space dimensions and the one time dimension, nothing can travel faster than the speed of light. So it looks like this

D1+D2+D3+Time=speed of light, always, so if you travel faster than the speed of light than time would have to be negative thus traveling back in time.

Answer 4

The only known way to see your past in actual time as opposed to looking at recorded images, is to look in a mirror. The reflection you see is in fact older by a few milliseconds. What we see is dictated by the speed of light and that light entering our eyes, so in effect looking in a mirror is technically looking at your past.

Answer 5

try a idea try. If the Universe all started from a singularity and then prolonged to the scale that is now, the position would you spot the enormous Bang? it really is precise, everywhere. in case you had a telescope effectual sufficient to work out decrease back to the enormous Bang, and if seen mild had existed at that second (it did not) you'll see the enormous Bang everywhere you appeared.

Answer 6

Past-life regression hypnosis is a possibility.

Answer 7

Travel very far at faster than light speed and look back at your launch point with an extremely powerful telescope.

Answer 8

A time machine is obviously the best answer for this question.

Answer 9

It is all in your Mind. Just roll your eyes back into your head and look.

Answer 10

Never heard of photograph albums?
