No weight, but relativistic mass! (which i'm sure you know, but for those who don't). Which basically means it has mass because it has energy because it is moving, and they're basically different manefestations of the same thing.

Warping space to move through space faster than light does not mean you are actually moving faster than light. When warping you are changing the distance, not the speed There is absolutely no way to break the light speed barrier. However, that doesn't prevent us from getting from A to B faster than light does.

You can't really see black holes. There are special techniques for spotting them though. A big spinning cloud of gas? A galaxy? There is a supermassive black hole at the center of our galaxy and all galaxies for that matter.

You wouldn't exist in view for eternity if you flew into it. I suppose in theory you wouldn't cross the event horizon, but it's not like this has been tested. Time would indeed slow and they would appear to be moving very slowly from your point of view (and this is assuming you could even observe them XD A BIG ASSUMPTION!). But remember, time only dilates extremely at ridiculously large energies/masses. Near the event horizon you're not going to 'stop'. You're going to be starting to slow down rapidly to an observer, but not stop. And then at that point you're going to f'ing DIE (and your ship annihilated). The outside observer likely would not see any of this though. But neither would you inside the ship! You will not exist long before you reach the singularity, which is where you may or may not stop completely, but you're not going to find out!

You say there ARE tachyons, when they aren't actually real. String theory is bolded for emphasis because it's not actually science. Nothing can travel faster than light.

And LK, a couple of things. One, you can't go faster than the speed of light, so there's no point in even drawing a conjecture as to what might happen.

Two, time is relative. If you're going near the speed of light, your watch is going to tick away just as it always did.

Light is just a particle, the theory that light somehow sets the limit on speed is ridiculous. Einstein is cool and all, but instantanious travel has been accomplished at the subatomic level. Making transmissions faster than light. Travel no, but there are some very good working theories being put to test this year, I'll rub it in your face when they work out mkay.

You're probably talking about quantum entanglement which is not travel.

I said transmission, I admitted that it wasn't travel.

good point

edit: oh wait, you contradicted yourself o_O Anyway, it's not technically "transmission" either - it's just an interdependency at this point. No ansibles yet. 8)

Instantaneous information transmission is doable (Schrödinger's kittens, anyone?), but not mass transfer. You say instantaneous travel has been accomplished, but you offer no source. Come back with a link or article that can be scrutinized.

Why you have a problem with the speed of light is beyond me. Nothing's been seen to move faster, and relativism has proven with empirical evidence that nothing CAN move faster.

I said travel, but later transmission, if I wanted a grammar award I would, well i dont want a grammar award.

Anyway, there have been some cool experiments with quatum reality, there has been visible objects which are the same occupying two points in space. Quantum variables are really interesting but I still havn't read up on them as much as I would have liked too, all my time at home is dedicated to writing my sci fi novel and I havn't reached the IT part yet.

I can't find the site now but there was an experiment where they had a photon go into a new quatum variable changing it's location. Also WTF Do We Know has a reference to it.

First of all that has nothing to do with grammar, and second of all that's a convenient excuse that doesn't count for anything o_O People who read your posts assume that you said what you meant, and this is a highly reasonable assumption. Another way to say it is that people respond to what you say, not what you mean. Deal with it o_O if you made a mistake when posting, correct yourself, don't blame people for misunderstanding you.

Also, as to the speed of light, not only is it impossible to exceed it according to the theories of relativity, but it is actually meaningless to exceed it (just like you can't go slower than standing still). It's part of the definition of the space-time continuum. If it seems like an arbitrary "speed limit" to you, that's because our units of measurement of speed are arbitrary.

I know all about relativity, I just happen to go along with a theory that is is wrong. I did read up on relativity a long time ago and now you had to go and make me find it again. http://www.spaceandmotion.com/Physic...Relativity.htm

You can't travel faster than light directly because of E= mc^2/(1-v^2/c^2). The full equation, clearly stating that at C, something of mass would have INFINITE ENERGY! Thus it is impossible, end of argument.

This states nothing about string - warp - or any other form of movement where your velocity isn't actually exceeding C. They've already broken the light barrier with massless particles moving them from A to B at about 300 times C. However, the particles did NOT move faster than C

Talking Re: Dissipation of light?

light cannot pass through non porress object like lead and its is technically an element but in places like space were ther is no oxygen then light can pass indefinitly unless there is a black whole where it absorbs all of the light
so let me explane wat a black whole is


it starts when a star turns super nova and collapses from its own gravity instantly creating total darkness because it bends light and disperses it into a different dimension where it continues indefinatly so to answer your question i would have give a course of energy and antimatter dispersion through alternet diminsions so basically light countinues indefinantly

WOW.

I know that this guy is banned and probably won't ever see this, but that is some of the most uninformed drivel I've ever seen.

Anyone reading this thread, please just forget everything skyrunner posts. It's for your own good.
