Faster than light

yes you would need exotic matter for a wormhole, but scientists doesnt know if that exist, and to create a wormhole you need a white hole (made of exotic matter). we make a blackhole here whit normal matter which worx like a convex lens, and a whitehole at the end of the worm hole to like a spreading lens. if you have a worm hole based on black-black you get a wormhole were you get stuck in the middle, both holes is trying to eject you from the other side, but whit a black-white wormhole you have 1 which tries to eject you from the other and 1 to eject from it self, you got a end :D sadly you can go throught that hole tog et back, you need a new hole for that. and keeping a wormhole alive costs, both black/white holes is ejecting matter in form of hawking radiation. so it will die out after some time (most likly after we have decied not to use it anymore) but we also need negativ energy to keep it open, so ure still paying a constant energy price. the negative energy cost 2

We make a black hole here with normal matter which works like a convex lens, and a white hole at the other end of the wormhole [to like] a spreading lens. If you have a wormhole with two black holes you get a wormhole where you get stuck in the middle, as both holes are trying to eject you from the other side, but with a black-white wormhole you have one which tries to eject you from the other and one that tries to eject you from itself. Sadly you cannot go through that hole to get back, you need a new hole for that. And keeping a wormhole alive costs, both black/white holes is ejecting matter in form of hawking radiation. So it will die after some time (most likely after we have decided not to use it anymore) but we also need negative energy to keep it open, so you're still paying a constant energy price.

The bits in square brackets are the bits I didn't get.
The half-life of a black-hole is long enough to negate that type of 'hole death within any reasonable time framework. And the exotic matter is the antigravity type, foo' - it keeps the wormhole open by pushing away from itself.

Hmmm , well I am a beleaver in dreams , I think its a way of comunication , just like radio waves. I got this funny dream once that the closest Inhabited planet (with smart beings) is 35 light years away. (I might off read it from a news paper, anyway thats not the main point)
If we get atleast 1 ufo an hour arround the world somewear, Don't you think thouse ET's even from the closest Inhabited planet [you]Don't [/you] wait 35 years at light speed just to reach earth , witch (by the same reasoning) is inhabited by very simple life.
The point is there is deffinetly a way to travel faster then light , and ^ here is my prove.

Here is an interesting question to think about.
First of all, light speed is supposed to be a universal constant. Yet relativity says that all velocity can only be measured relative to something else.
So what the heck is light speed relative to?
Another thing.
If spaceship A travels at 90% of the speed of light (which is definitely possible under Einsteins rules) and it meets another spaceship going the exact opposit direction at 90% of the speed of light then they pass each other at a relative speed of 1.8 times the speed of light.
Wouldn't you say that this proves that it is quite possible to exceed the speed of light since all velocity is relative to a point of reference.
Another example is that distant galaxies are supposed to be moving away from us at incredible speeds. Significant fractions of the speed of light. Try accelerating away from them and your combined speed will be much more than C.
There are a bunch of other unexplainable things about relativity too.
More later

shvarz:
PY, you have no clue about the relativity theory, don't you :)
Sorry, but it is obvious :)
Without going into details, think about it this way: don't you think that tens of thousands of scientists would not think about the example of two ships going towards each other with speeds over 1/2 of light speed? :)
I would recommend reading some very basic book about theory of relativity (just pick one in a library) - the basics are very elegant and easy to understand. And most books do consider these fun cases that seem to "disprove" the theory :)
