We could travel backwards in time if we found a way of making reality go backwards. Since it would be clearly impossible to put the whole universe into reverse, we'd have to find a way of making it happen to a specific thing or matrix of things.
I suppose geep could do the math for that if he's so kindly inclined, but I suspect it would take an unfeasible amount of energy to rerun the 2pm at Ascot for you.

Light speed is impossible for matter as we currently understand

Pickle, not quite:
Quote:
So, when we move, at whatever speed, time slows down relative to a stationary observer. Note that for the occupants of a rocket travelling at very high speeds time would still seem to pass normally. However, if they could see out to an Earth-bound clock it would appear, to them, to be running too quickly. If an Earth-bound observer could see a clock inside the rocket it would appear to be running too slowly. This is why the theory is called "relativity", it is because time is relative to whoever is observing it at a particular speed.

The human race will have ended a long time before it has evolved to produce vehicles capable of travelling beyond the speed of light - 2/3 of a billion miles per hour, by the way.

Let me make this simple:
You can travel FORWARD in time.
You cannot travel BACKWARD.
Is that clear enough?

Re: Is time travel possible?

Way I see it is this, though please correct me if I'm wrong.
Time is just how we measure things. If you have a road from here to Clapham what is real is the road, not the inches or miles we use to measure it. So time is an apriori figment of our imagination we use to make sense of the world around us as it changes. And when things speed up enough like they do in a travelling spaceship, the time figment loses all relevance. This is why there is no reference to time in E=MC2.

So infidel when will it be possible to go back and with the results of the racing at Ascot and have a big bet on them?

Time travel cannot be 'ruled out'. It is necessarily possible because of Einstein's theory of special relativity, which has been proved to be true already.
NASA once synchronised two atomic clocks and sent one of them around the world in a Boeing 747. When it came back it was behind the other one.
Similarly the clocks on the Space Shuttle always came back behind the clocks on Earth, with which they had been synchronised before the mission.
But of course the differences in these cases are minimal because the relative speeds are so similar. When we get a really fast spaceship - which is bound to happen sooner or later - and embark on longer missions then all astronauts will travel into the future.

My own crackpot theory is there's a major discovery to be made that will answer some of the unsolved riddles of the universe and rule time travel out. Have broached this to Blagg Jnr who is a Science Teacher and he thinks I'm an idiot (no change there then).
It's so complex I can't even imagine what it is - something like a brick wall being found at the end of the speed of light - but it will change the whole way the universe is viewed and my name will be feted forever more.

Theoretically, you wouldn't know if things were being changed as you'd be changed along with them.
Numerous incidents in history of people claiming to be from another time. Pretty much all of them looked up in asylums. If you travelled back, would you tell anyone?
Given one of the latest theories is that we are all in a simulation anyway, does it really matter?

Watch the Futurama episode - The Late Philip J. Fry. Future time travel and its perils will be explained.

Time travel does exist. Last Saturday evening I was in the pub when all of a sudden everything became blurred and swirly. A bit like being caught in a whirlpool. All of a sudden I was transported to the next morning where I had been placed on top of my bed in just my under pants.

No. If it were possible we would have future people popping back changing the course of history all the time...
It has to be impossible...
