True physical Speed of light travel will never happen imho.

Like Einsteins Theory states, the closer you get to speed of light the more energy it would require to go faster and this increases to infinity the closer you get to light speed.

Warp technology and Hyper-Space travel are the only ways to surpass the speed of light limitations and with those, you aren't actualy traveling faster then the speed of light.

With Warp technology, your actualy standing still and warp the space/time around your vesel to achieve forward motion, but your vesel is actualy standing still.

With Hyper-Space technology, you transit your ship into hyper-space, a layer of space/time where traveling 1 lightyear callculates to traveling, say, 1000 lightyears in normal space/time.

If the speed of light is calculated by how far light can travel in a years time "light year", and the distance to a long away star... the star is, let's say for the sake of argument, 100,000,000 (one hundred million) light years away... would the star in question is actually being viewed from 100,000,000 years ago?

Time travel?

No, it wouldn't.

Watch a football match live, if someone kicks the ball, you see the ball move, then a second or so later, you hear the kick. Now, are you watching the future when you see the kick, or are you hearing the past when you hear the kick?

If I left earth for the sun at say 2 times the speed of light [in a warp field], I'd get there in 3/4 or so minutes. Then if I immediately turned back, I'd arrive at earth 8 or so minutes after I left = no time travel. It could be viewed as no different to travelling across time zones - moving from earth time to sun time same as moving from GMT to GMT+5, while the local hour may change, the universal time-line has not moved backward.

By the way how dose the einstein's theory work (I mean the one which states that you need more energy to go faster the faster you go).

I find this hard to belive since speed is so relative concept. what is the "zero point" speed - there is no such a thing everything is so relative velocity just compares the speed between two objects. (just like someone here mentoined).

Anyway I didn't think about this for too long and only in basic concepts so my response might be highly flawed...

anyway if someone has some links to this theory I am too tiered and stupid to think on my own

I think the light you are seeing is 100,000,000 years old - the star would be older.

I'm not sure even if you had ftl you could reach the star before it had expired.

For arguments sake, lets say a new star appeared in our nights sky and we had the ability to get there in a few hours, those few hours are still relative in earths time regardless how far out you are. If you were to turn back and 'only' travel at lightspeed back to earth, you would age as per normal and would never make it back to earth in your lifetime.
Following these basics figures, time travel is not possible.

I've been wrong before though

It would not take 4 years, you would be there instantly when you travel at the speed of light, so it is not a problem. Only when you want to come back to earth (you would be back instantly as well), you will discover that all your family and friends are dead as many years have passed here.

I could be wrong here, but im sure that light speed cant be exceeded because light is always travelling at the same velocity, so if you were travelling at light speed from a standing observers view, light is still travelling at light speed from you, so you could never truly go faster than light? I think thats where space time comes in, not sure, just going by what i remember seeing somewhere on theoretical time travel.

answer is no it would not exceed the speed of light, even if it could reach it, which it couldnt.

I very nearly said that you wouldn't be able to withstand the centrifugal force - then realised that there's no gravity in space - not sure if centrifugal force works in space

Would this create an artificial gravity anyway?

The problem as other posters have stated is that the closer an object comes to the speed of light then the more energy (or torque) you need to push it, at the speed of light the amount of energy needed to spin the object faster becomes infinite and so it can't be done.

This is only true if "Special relativity" is true though, I have no reason to think that it isn't

Yes the amount of energy needed would increase due to the increasing of the mass which is accelerating. The idea is that probably can't reach 100% the speed of light; but as long as we had a motor powerful enough; 99.999999999999999% may be reachable; and in turn may be able to manifest man made black holes.
