Someone bring out the projector. We are going to watch a space movie about "warp drives and worm holes". You may bring a snack or a juicebox if you like.

Your quite right that if an object in space, accelerating under a constant force, were to have its mass increased up to a fixed mass value, then it would just take longer for that object to reach light speed - but it would still eventually hit that speed.Quote:

There is no gravity, and it is a vacuum, therfore no friction to act upon the object, so ANY force acted upon a spacecraft should influence it. Let's say that a craft DOES increase in mass, then it should only take a lot longer to reach lightspeed, but it should be able to happen. I dunno, people tell me it is impossible, and it very well may be, but a lot of this doesn't seem right. Perhaps I am being given the wrong information and/or remembering the wrong facts.
However, since Acceleration = (Force / Mass), you see that when the object's mass increases without bound (as its velocity increases toward light speed), then its acceleration actually diminishes to zero... thus preventing the object's velocity from ever actually achieving the light speed max.
All this at least in theory... somebody please correct me if any of this is incorrect?...
Edited for typo...

what a lot of msgs!...maybe already said, but i had a friend who did astrophysics at uni. I was told if a space ship 2 miles long is travelling at half the speed of light, it's size shrinks by half. It can then be stored for a fraction of a second in a room 1 mile long.
wee-yuurd ;-)

Rutrow, it says that feature is available only with the purchase of a BORG transwarp drive.
SOL.
hey if i every get 15 grand i can buy me a dalorian... one for sale 30 miles from me.. how phat would that be riding downt he street in the backtothe future car with 20's and hydrolics!!!!

Umm actually I find your topics very enjoyable and quite amuzing https://www.sharkyforums.com/images/.../2005/06/5.gif. I do however think this is VERY possible indeed but not of our time as of present. I have seen it happen in movies of course (key word MOVIES) and seems like a very futuristic thing that could very well happen if we keep advancing like we are now. Space is still very much unknown and for thousands and maybe millions of years let alone forever always will remain that way. I dont think anyone can fully understand the true powers of the universe.
I hate to revive a dead thread but I read through and found this one particularly interesting. It sounds possible in theory but when you try to apply it, it can't be done(kind of like Communism). I do believe we will be able to travel at the speed of light (not in the near future), but will never be able to travel backwards in time.
Actually, going by this theory, how would you even be able to move your arm forward to throw the ball, or how would your heart pump blood towards the direction your traveling? I admit that I'm quite ignorant when it comes to...well, pretty much anything, but wouldnt your arm or whatever other object be held to the same rules as the ball?Quote:

I asked him the following.
What if I'm a galatic post man and I stand on my space ship going at the speed of light.
I have nothing to do so I through a boll in the direction I'm going.
Normal math states current speed + added speed (boll) = total speed for boll.
looking from a stand still position.
The boll would be traveling faster then the speed of light right.
NO was the asnwear I got. He said that the boll would NOT leave my hand because nothing can go faster then the speed of light.
By all means do. I have it immortalized on CD now anyways(I do that). Do with her as you wish boys, she's all yours. Thanks for the interest. :)Quote:
