Perhaps we do not yet have a way of knowing at what speed, IF speed is a factor, we need to be traveling to "physically" go back in time to, for example, see our birth etc. Perhaps we don't need to travel at any speed at all or spend any time at all going back in time. Perhaps we can actually experience time travel without spending 1 second of time from our present traveling but we could spend years in the past. I still see travelling at the speed of light only effective in SEEING the past, not living in the past or being able to change anything. The people that we knew that maybe passed on, we would see them but we would not be "with" them.
Let's go back to the flashlight. You point it at the wall and switch it on and then off again in 5 seconds - then off you go at the speed of light - you will NEVER see it again, unless you travel at more than 5x the speed of light, to reach it's "front", OR you would be traveling with the present that passed when you left and so time would stand still, right - yeah theoretically. NOW think of it this way, switch it on and travel with the light; time didn't stop just because you were traveling at the speed of light towards the wall, it continued to move forward OR the light would stop dead and never reach the wall - and you wouldn't go splat!
weird? hmmmm... imagine a fly stopping a train!! OK - the fly moving east and the train moving west. The fly hits the front of the train and then starts moving west WITH the train. Now an object needs to stop moving, IF on a specific path, to go in the opposite direction along the same path. That says that the moment the fly stops to change direction it is against the train and then gathers momentum in the opposite direction. At the very time the fly is stationery SO IS the train - it has to be - think about it or the fly would never change direction if it didn't have to stop. I can't explain it any better
- Now i know there will be hundreds of proven facts about why the train didn't stop etc etc etc, but that's a human
way of thinking but if you really close your eyes and imagine the scenario, for a billionth (not accurate) of a second both the train and the fly are
stationery OR the fly would have never stopped. Like i said, IMAGINE. Did I make sense? We are thinking of time travel based on what Einstein theorized. I don't believe it is possible in the physical sense in terms of interacting with the past.



That should get your minds thinking.
I don't know what to think now upon second confirmation.
