[QUOTE=sltungle;32351242]We exploit little loop-holes in the universes physical laws all of the times to do things that otherwise can't be done. We exploit quantum effects and attempt to cheat probability in order to make faster and faster computer processors. We create meta materials with negative refractive indexes simply because we can. In a less rigorous sense we cheat energy requirements in chemical reactions by finding catalysts to lower the activation energy of certain reactions so that they're easy to achieve. If there are loopholes to be exploited we will find them. And there are always loopholes (in the case of 'FTL' travel wormholes and Alcubierre Drive are those loopholes, however that said the energy requirements are still incredibly high in our present theoretical framework but I'm sure we'll be able to cheat the universe and find a way around those energy requirements too if we're persistent enough).[/QUOTE] But surely these are 'loop holes' of our theories which aren't perfect?
[QUOTE=Rct33;32358223]But surely these are 'loop holes' of our theories which aren't perfect?[/QUOTE] Well when you're talking about what we may or may not be wrong about, there's really no way to know. We [I]think[/I] we're right about a lot of our theories, and the most commonly accepted ones normally have conclusive evidence to support them, but there's a decent chance science has been feeding you a constant stream of bullshit since you were born. The world's kinda Lovecraftian, when you think about it.

Quantum mechanics is certainly weird, but it follows its own set of rules, even if they seem to contradict those of relativity. I'm just saying that reading the rules and trying to break them isn't terribly productive, because all our weird advancements (like, as you said, quantum computing) are still following known rules- what makes them seem like 'cheats' is that under certain paradigms we take for granted (like classical logic) they're not possible, but really that's just applying the wrong set of rules.
I definitely think moving past the speed of light is impossible, due to energy requirements. However, if we could find a way to warp space to our will and use it to push/move our ships, then maybe FTL travel is possible. But until then, there is no "magical" answer to our problem. Until we can find a way to go FTL, space colonization would be hard. But hey, what do I know. I'm only in high school. These are just thoughts.

These are just thoughts.[/QUOTE] it's already been discussed, and as far as I can tell the whole space folding theory- though getting you from point A to point B much faster than light would have traveled on its own to the point*- is not FTL in regards to what this thread is specifically talking about. *technically slower than light anyways if you account for light traveling through the same space you're bending through
[QUOTE=ExplodingGuy;32350449]Even with the Alcubierre Drive, there's a huge possibility you'll need more energy than contained in the entire universe. Also, as Lankist said, it's not FTL.[/QUOTE] The truth is, there's currently multiple mathematical models which range from relatively small energy requirement to exorbitant ones. Also yes - as far as we know conventional FTL is not possible. Hence the theories on nonconventional FTL travel.

I do believe neutrinos just dry-fucked Einstein.
Facepunch: Where peer review is unnecessary.
I don't trust it unless it's in a journal. Bad science runs to the media.

They're submitting the process to the scientific community to confirm it. Not likely to lead to breakthroughs in FTL travel, though, that much is sure.

Hey you guys just wanted to let you know that they just found particles which travel faster than light.
FP never ceases to jump the gun.
[QUOTE=Block;32350948]A black hole doesn't "destroy matter", it destroys information. [/QUOTE] ?!?!? Information can't disappear, it can only become messed up through entropy, but it doesn't disappear.

Not when a discovery is (possibly) made that (possibly) contradicts everything we've so-far established. If Scientists (possibly) received a signal with (possibly) intelligible (possible) information and told the public about it, you'd have people in the streets holding signs, "I, for one, welcome our new alien overlords," or something. :v:

Where is your theory now, OP?
[QUOTE=barttool;32436784]Where is your theory now, OP?[/QUOTE] In every modern physics textbook, same as before.
Human science is always changing. In 200 years we'll have infinite energy machines and FTL travel. Just watch.
