some physicists assume they know something when they have no proof that it is absolutely true
Physicists love nothing more than to be proved wrong, because that points them in the direction of the correct answer.
what are the possible forms of faster than light intersteller spaceflight?
there is the alcumbierre drive
No. Proving other physicists wrong is much more fun than being proven wrong. 😛
The "warp" drive is hypothetically possible, but we'd have to discover exotic matter, and we don't even know if it exists or not. It should exist, but we're clueless as to how to produce it. If we can find exotic matter, it would also give us Star Wars type of technology- mainly with floating cars, ships, and the ability to move huge masses with little power.
Wormholes are the other form of FTL. However, the energy requirements for this form of travel are practically impossible.
There's some other ideas about FTL - extradmentional travel is one (if we can figure out how to penetrate and send information through higher dimensions). This would be like "hyperspace" in Star Wars, or sub-space in Star Trek.
I don't see why anything should exist. Explain please? I hope it's not just so humans can travel and explore space easier. The universe is not here just so humans can have their way, sorry to break it to some of you.
At the risk of misinterpreting Fritzo, I think he's saying that there are various hypotheses involving unified physics where the math suggests that exotic matter does exist. However, I don't think any of those are all that well supported (I'm open to being pointed at evidence to the contrary). I wouldn't have worded the statement quite as strongly, but I understand where he's coming from.
I think you just invented the Alanis drive. We mount her to a pusher plate on the back of a spaceship. Her voice repels the universe at faster than light speed and off we go.<Alanis>
Isn't it ironic? Don't you think?
</Alanis>

There's a saying that goes "if something can exist, it most likely does exist". The specific property of exotic matter that we would need for a warp drive, anti-gravity transportation, and so forth is matter with negative mass. Matter with negative mass is can exist mathematically, and it does not violate any laws of conservation of momentum or energy.
So, since there is no reason it should not exist, it should be there. This same reasoning is what lead to the discovery of the Higgs boson. We couldn't detect it, but there was no reason it shouldn't exist and it solved a lot of problems.
Scientific theories that match observed phenomena sometimes rely on the existence of as yet unobserved phenomena to make sense. It's quite a big deal when these unobserved phenomena are later confirmed. Nobel prizes have been won just for confirmation of predictions made by relativity and evolution. I think it's incredible to see that happen. Exotic matter would fall into that category.

This. I can't decide if completely insane or very dedicated troll. Funny either way!
i believe that the mtDNA in most of the world pop was artificially formed from elements, minerals, and whatnot from the earth while the minority (not more than 3/10 of all classified as humans living today and not less than 1/40 of all people classified as humans living today) has a matrilineal ancestor directly created by their god and that that creation took place in siberia.
so to answer the OP's question... some people (all those with neanderthal mtDNA which are hgs UK, A, and D) are natural/designed intelligently and they have a supernatural soul since they were created by their god all at once. "modern man", the majority of all people classified as homo sapiens today, have mtDNA that was artificially made though because their mtDNA is closely related to monkeys.
the cro magnon man looked much more like chimpanzees than the neanerthal man did because the former had a narrower head, shorter face, weak legs/knees, smaller nose, narrow pelvis, and lower to upper limb ratios closer to chimpanzees... neanderthal is the opposite of the chimpanzee because the first neanderthal female was created directly by her God while the chimpanzee shares a common ancestor with monkeys as do all classified as hominids except for neanderthals
