These are just Random Thoughts/Musings and may be utter nonsense.

__Hypothetical Idea: Time Penetrating Radar__

A time radar would be a device that projects faster than light particles into the future which bounce, like a radar, off of a future object and back into the present. With such a radar, a military vehicle, like a tank could see the future position of an enemy vehicle.

__Time Travelling Rabbit__

A rabbit decides to run from point A to point B

He sets off from point A at 4 O’Clock and arrives at point B at Ten Minutes Past 4

The next day, he decides, “I’ll run faster than I did yesterday” and , setting off at 4 O’Clock, he runs faster than he did the day before and reaches point B at 5 Minutes past 4

But the next day he decides, “I’ll run even faster than that today”, so he sets off from point A at 4 O’clock and, this time, he runs so fast that he actually manages to arrive at point B at 4 O’Clock; he’s travelled so fast that his journey was instantaneous.

“Wow, that was amazing”, he thinks, “I wonder what would happen if I travelled even faster than that”.

So, setting off from point A at 4 O’Clock, the rabbit runs even faster than he did the day before and, this time, he runs so fast that he actually manages to arrive before 4 O’Clock; he arrives at 5 minutes to four; he has gone back in time.

__Time Travelling Tachyons__

Perhaps, because Tachyons are so fast; fast enough to break the time barrier, they are constantly travelling backwards through time and that is why scientists haven't observed them. Perhaps they should be looking for something travelling backwards in time.

__All backwards time travel seems paradoxical__

Any person wishing to go backwards in time would also be going forwards in time and that is paradoxical.

For example if I were to go backwards an hour in a time machine how long would it take me to make that journey? However long it takes me to make that journey would be time that has moved forwards.

And compare this to travelling both backwards and forwards in space simultaneously. It can’t be done.

__Travel By Time bubble/Separate Time Stream Seems Paradoxical__

People talk about time bubbles or time streams where a person inside a bubble would occupy their own separate time from the time outside the bubble.

But I think that this is also paradoxical. If the time bubble which you are in is moving backwards in time whilst, inside, you are moving forwards in time then you and the time bubble are moving in two different directions. A time traveller wouldn’t be able to stay inside that time bubble/stream.

### as you travel faster and

as you travel faster and faster mass increases so the question is would the same rabbit arrive?

### that's true, but as you

that's true, but as you approach the speed of light I think a different equation kicks in. einstein's variant of the special theory of relativity. I'm not a big physic's head either. different laws apply for the very big and very small.

### the Lorentz factor is the

the Lorentz factor is the main thing here I'd guess. All things become interchangeable.
