We don't have Hovis in the future.

Now we know you're lying Hovis shall live on so long as there's proof needed!
Right, this is my opinion.
In essense this means that if we travelled faster than the speed of light you could travel away from something and see something which happened previously. And if essense you are seeing something from the past, hence you could travel away from something faster than the speed of light and then watch as the light. For example if something happened yesterday on earth you could travel away from the earth for 1 day at twice the speed of light, then look at the light from the earth you would see what happened yesterday now. ie. Time travel.
However what you cannot do is travel faster than the speed of light to interact with the past. As it's already happened.

We were led to believe that nothing can travel faster than the speed of light! However their are now claims that particles have been proven to travel faster than this.

It’s not a thin argument it’s a massive problem most people overlook when talking about time travail. I don’t think you understand the sheer size or speeds we are talking about here. What is a thin argument is you saying but we could just compensate for this very real problem in some unknown way. You would have no point of reference, no idea where Earth had moved to and even if you did if you are just 1/10000 of a degree out and you still miss Earth by a long shot. It’s a massive problem.
How do we know that the powers at be weren't told that in the future Saddam hussein makes a nuclear bomb and destroys the US or UK or both. And that we had to make up some crappy excuse to go to war in order to stop future events.
Maybe the future knows that if they came back and gave us time travel we would probably **** it up.
Unless someone turned on a time machine or created a wormhole or something ages ago then that's not going to ever happen because there'd be no way for anyone to travel back
1) Go back in time 1 hour.
2) Realise you are where the earth was 1 hour ago in it's orbit.
3) Asphyxiate in the cold hard vacuum of space.
4) ???
5) Profit.
In many ways the changes of time travel are easy compared to the spatial challenges involved. It’s perfectly reasonable to think time travel can get invented but the spatial challenges not be solved.Right, so we can hypothetically surmount the challenges of time travel, but we can't get around the spatial challenges involved. Hmmm. Never mind the fact that we can and routinely do plot the movements of numerous stellar bodies.
Honestly. It's a simple relative movement problem. It's hitting a moving target - something we do all the time. Hell, people have been doing this sort of thing with bows and arrows for thousands of years. All we're doing is adding a dimension and increasing the precision needed. It's really not a big deal......
It’s not a travel problem it’s currently impossible. How do we work out our movement in relation to the universe? Even on the smaller and easier scale but still impossible today how do we work out our movement in relation to other galaxy’s? Scale it down more how do we work out our movement in relation to nearby solar systems?Step 4) is that you quickly travel back in time to 1)a) and compensate for the relative motion of the universe, which is a trivial problem, and something that we are already good at calculating.
You can actually interact with the past if you travel faster than the speed of light, and more importantly you can violate causality (i.e. you could receive a message before you even sent it).
It's a fairly straightforward proof that this is the case, but if you didn't do undergrad physics or maths it might be lost on you (no offence). I believe I posted this on another similar thread, but here is a wordy explanation of how it's possible:

link above said:A brief note to my recent visitors: If you’ve arrived here from sites with highly misleading blurbs and expect to find a discussion of how faster-than-light travel is possible, I’m afraid you will be disappointed. This article outlines an argument commonly accepted by physicists which demonstrates that in special relativity faster-than-light travel is not possible
Because it's all theory, there are very little practical applications for most theoretical physics.
reading the article and the comments, it doesn't prove anything like you are suggesting. well, the theory does indeed backup the theory but that doesn't prove the reality.
