Its a theory which I came up with myself, I am sure there are over payed preachers out there who harp on about the same principles though.

I have some funny thought provoking ideas sometimes....like...

If you could travel faster than the speed of light and you traveled from the earth to the moon and then looked back at the earth.....what would you see.....

The truth is....nobody knows.....do you see an image of yourself coming toward you.....does the image crash into the already parked craft.....is an exact copy of you now in existence (assuming you had moved your craft by remote after you had got out of it) which is permanently copying what you did a period of time ago.....

Do you now still think we can travel faster than the speed of light.....without resorting to alternative route technology (worm holes etc)....

Interesting stuff, and following on from that..........

What if you could travel at twice the speed of light and you travelled to a planet 1 light year away from Earth and then back again. What would the scenario be? Would you arrive back on Earth 2 years before you left? Would you meet a 2 year younger version of yourself? Would you be able to prevent yourself from leaving Earth in the first place?......and so on. Mind boggling stuff!! :-? :P

I suspect many thing will be possible in the future, but not faster than light travel. Worm holes may well be a means of connecting different parts of the universe and one day it may be possible to utilise them for space travel, and who knows what lies within or beyond a black hole!! :-/

**edit** Apologies for going off thread a bit but an interesting subject raised my Mark.



Well this messes up theory of relativity so I am assuming some form of inertialless drive or warp drive borrowing terms from EE Smith and Star Trek.

Your round trip would take a year Earth time, I have no idea how long local time would be, but it would be interesting to find out.

Wormholes? Do you have a Farscape module handy?

Yes, it's mind boggling. My own favourite is as follows:

If you throw a tennis ball at the front of a locomotive travelling at speed, it will bounce off. I believe that there is a law of physics which states that before an obeject (the tennis ball, in this case) can reverse along its previous trajectory, its forward speed must reach zero. Therefore at that split millionth of nanosecond that the ball strikes and achieves zero mph, it is in physical contact with the train, which must logically also be travelling at zero mph.

Is this too far off thread?  ::)

The ball deforms a lot, the cab front/smokebox deforms a very little, perhaps compressed a few atomic spacings in with a smoke box (cast steel) or 1/100mm for a cab with sheet steel.

True, but the nucleus of the ball (assuming it doesn't deform completely) will achieve zero speed and the compressed metal on the cab will, before it springs back also achieve zero speed. Thus, with the tennis ball and the cab front physically joined, even at maximum compression, atomic parts of the ball and the train must both achieve zero speed at the same time....or not!   :-/

I guess the light would create the equivilant of a sonic boom and you would see a single image representing what the last thing in view was before the light barrier was broken.  

I also suspect that the pain killers for your knees are bloody strong!  ;D ;)

Surely travelling faster than light speed would be very dangerous.  You wouldn't see the tree/asteroid/small planet till after you hit it because you would have reached it before the light had reached your eye to see it. Or am I just being silly now? ;D

I'm having some difficulty deciding whether you all actually know the currently accepted "correct"  answers to these ponderings, or whether I should actually answer them.....

May I recommend some reading material for our thinkers here?

For starters, stop thnking in terms of physics as you know it.

This is what theoretical quantum mechanics was developed to "explain".

A brief history of time: Professor Stephen Hawking.

probably not.....  given that you'd achieve near infinite mass....    i'd think you would be much more concerned about your dieting regime
