The closer you get to the speed of light the more time slows down for you compared to a stationary observer.
This is what im talking about. Using my train example to the outside world everything inside the train would look like it was happening in slow motion.
I think thats right anyway.
You were right Jonny, you got in before I replied to Steve.

You are only slowing down your eyes perception of time though, you arent actually slowing time itself down, to everyone else time remains the same

I've actually invented a device, but would need to be built and setup now and its only useful in the future to look at the past, needs to be positioned a light year away from earth though. So we wouldn't see much benefit from it.

Say to travel back to a previous year, you would have to travel so fast as to "catch up" with the light from that era, you would only be seeing whats happening, like a movie

That's not how it works.
You aren't changing your perception of it at all, time still travels at the same rate for you.

Isnt that what time travel is though? You go to a year in the future without aging (near enough) and everyone else goes on with life as if nothing happened.
yeah but im just wondering wether all you would do is see whats going on, you wouldnt say for example be able to converse with someone from that time, or change anything at all as a result of you being there

Deleted my post as John has explained it better.
I've already said time travel backwards is theoretically impossible. Read up on the grandfather paradox.

This is starting to sound like my device.
You just see the light from a light year ago

I can get my head round time travel being theoretically possible backwards, but not forwards, things havent happened yet in the future, unlesshow it would work is everything just goes into like fast forward mode whilst stays the same for you, you just everything happening really quickly until you slowed down

Think of it like an ice cube, once it melts you can't go back in time to when the ice cube was frozen, but all the particles of the ice cube are still there, but in a different form.
You couldn't go back and see your dead grandad but his particles are still here in a different form

Steve you cant go backwards in time because if that was possible i could go back, shoot my own grandad and then i couldnt have been born, so how could i have gone back in time to shoot him.
You can go forward if you go fast enough.

yes i agree you cant physically go back in time, but you could see what happened back in time
when we see stars many thousands of light years away we are seeing how they were at a point thousands of years ago, some we see now dont even exist anymore
so in that sense its possible to take a snapshot of previous time

Yeah i get that. If you could get far enough from earth in an instant and look at it from 14 light years away you could see your own gf been born. Of course that would be pretty impossible as since you cant travel faster than light it would take you more than 14 years to get there, meaning you would only see what happened just after you left.
Do you understand the time travel forward thing though? Its really not that hard to grasp.

Thats the most wonderful thing you have learnt? Pretty basic stuff
Sorry Sir Patrick Moore.
I didn't say it was scientifically astonishing, just I felt it was rather cool.
One of the great mystery's of the Universe is how you haven't suffocated with your head up your arse so long.

Made me laugh, I'll give you that Sunz
TBF to you i do often look up at the stars and think its pretty cool that we are basically looking into the past.
Even cooler to think that if you were 200 million light years away from Earth and had an amazing telescope, you could see the dinosaurs.

They might have found the Higgs Boson but it will take more than CERN and billions of investment to find Steve's brain.
