Time travel/ Looking into the past???

from Sins Forums
I've just woken up from sleeping in the freezing cold caravan with a strange thought in my head. i thought i had better share it with as many people as possible b4 i forget it (which is what usually happens when i think of something). anyway, the thought was about timetravel. well not travel, but being able to "see" into the past. light bounces off everything, which then travels to our eyes, so we can see them. this light also bounces off in every direction (within a line of sight of the object) including out and into space.if there was a way (quite impossible with our current level of technology) to get to a point where the light hasnt reached yet, would we be able to see the object the light bounced off in the past? eg. the atomic bomb blew in 1945 (if i can remember my history) and its light reflected out into space, like a ripple of water from a splash. even now, that light is still going further out into space at the speed of light (duh!). if a ship was able to intercept it (either via FTL or wormhole) and had a VERY VERY good telescope, and looked back at Earth (which would be VERY far away)the crew would be able to "see" into the past. This is a really kewl idea, coz if it was successful, then events in the past could be supported with visual evidence from the ship. so we could find out what happened to those retarded dinosaurs! just something to think about, gets my head working. dunno bout u though

I think you'd need a telescope the size of a galaxy to get resolution worth a damn at that range.

Probably bigger, lol!

Lol, yes i know, but what if there was a way around needing a telescope. We could see into the past!!! i know its very impossible, but its a kewl concept to grasp.

eh, we need to go to the edge of the universe and take a look at the big bang

yeah...
dunno bout u though

congratulations. you discovered time travel!

yay!! ^^, anyway, looking at teh big bang would be kewl. it would be hard to miss *Giant flash followed by a bang....*

cept there wasnt a bang as there was no matter to transfer the waves

Yes it is possible to look back in time back looking far away. in acctual fact by looking into the nights sky we are seeeing stars thousands of years in the past. Even our sun is in the past by the time the light reaches our eyes it has been travaling for 6 minutes. We are capable of looking back to just after the big bang about 1 million years after it infact. this is the maximum you can look back. for reasons i cant be arsed to explain lol. (too complicated) which might i add is cool.  Time travel might i add is verry possible. scientist are working on a way of making a sort of tube or spiral of time which if you jump through will make you go back in time by a few microseconds. They know this by firing particles down it and some how noting their age. Also if you go into space and leave your freind back on earth. you both have an exactly the same watch on exactly the same time. say you go in orbit for a year your watches should be out by 0.5 of a second. this is cos the faster you travel the slowwer time gose. In fact satilites are configered to take this into account. Yes i do watch the discovery channel 2 much! lol

Lets assume we could get the telescope to the edge of the universe (we'll say 13 billion light years but there is a lot of debate on this) at the speed of light. By the time we'd hit the 13bn ly mark (in 13bn years), the universe would've expanded *another* 13bn light years, whats more, we'd look at Earth and see what happened, 13 billion years previously....ie the telescope would see itself being launched...

Mighty, he acknowledged that you'd need to break the light speed barrier.

it was a joke.... "the big bang". of course there is no sound in space!!!   and to the guy who said that by the time u get to where u think the light will be, only to arrive and found its moved further out into space. dude, its traveling at light speed. of course its gonna move away from where u thought it would be. thats y u plan ahead and go to a spot where it hasnt reached yet, then wait 4 it. and you could check out different eras in time depending on how far out u go, so it doesnt nessisarrily have to see its own launch.

You missed his point which was the light speed limit.

you need to have sharper objects...

You missed his point which was the light speed limit.

and his point is invalid as going that speed would flatten the universe to an infintesimal size, in which crossing would take seconds.


but THEN of course, what took you a few seconds actually took 13 blln years and you're back where you started...

I know, its just an interesting notion....

The theory of relativity is fun and all but don't ya think it would just be sooo much easier if we could go faster than light without the time dilation effects? Stupid universe...

well as long as I drag all my worldly possessions and my social slaves (some of you know them as "friends") along, I really dont need anything else.

well u could skip the whole lightspeed idea and travel via wornhole. this way, u dont have freaky time dilation effects, and can travel at normal speed *wotever that is in space*
