  1. But perhaps the universe itself is a single thing, thus if any part of it has formed, all of it has to have formed. In any case, the only real thing scientists know for certain about the early universe is that it appears to become hotter and denser as we rewind the cosmic video-camera. It's true that there could have been something before the big bang, but by definition, there could not have been anything before the creation of the universe, which is what we label the big bang as not knowing of where else the universe could have came from.
  2. This brings up a good point: If the forces in a black hole are as strong as we think they are, yet quarks cannot be broken down into any simpler particles (as far as evidence shows), what do they "break into" when the gravity becomes too much?
  3. You might want to look into quantum field theory It describes all matter and energy as oscillations of various fields, which sort of allows for relativity to takes place with out all of this mucking about with things having to be solid and act like spheres or bundles. Matter and anti-matter can be described as two different types of oscillations within the same type of field, so that when they are added, the net oscillation equals 0, as can be demonstrated by finding the sum of two sine waves of opposite signs.
  4. This... was a little different. When an atomic bomb explodes, it melts the local ground into a distinct glass. This same type of glass along with higher-than-normal radiation was found at the site in India covering a large area. Also, how long does it take for exposure from natural uranium to cause tumors? Because the channel also said that there were ancient depictions of people dying from what appears exactly like radiation poisoning in people who were transporting the Ark. In the depictions it seemed rather instantaneous, but it would make more sense if people kept coming to it and getting exposure, and then after like the 20th exposure they finally noticed a bunch of tumors, but I don't know if natural uranium is that radioactive. Are there naturally occurring materials on Earth that could cause radiation poisoning quite rapidly?
  5. Sure, but in the case of liquid helium, the only thing that's happening is that the atomic particles are moving closer together and staying closer togather, yet the substance exists primarily in a state of entanglement. In degenerate matter, the particles are also very close together, even if those particles aren't whole atoms.
  6. Well environmental instability is really the only way evolution proceeds, otherwise its all living things would just be completely random masses of DNA. There probably would be some animals too, but there would be an almost approaching infinite amount of diversity because any amount of any DNA could potentially be passed on without environmental restriction.
  7. So...what other simple thing do you do if you want to find the quotient of two polynomials? Calculators can have a few inconveniences, like if you say "what's negative 5 squared?" and just type it in, it will give you negative twenty five, you need to put parentheses around the -5. I'm sure if you worked out each step carefully there wouldn't errors. In my experiences, matrices lead to even more errors anyway.
  8. There was nothing before the big bang (as far as we know), not even time, and because time did not exist prior to the universe, the universe technically has always existed. There was nothing to count seconds before the universe, so it's technically infinite or at least undefined.
  9. If your traveling at the speed of light, how do you perceive distance equaling 0 when it takes time to reach a destination and a photon doesn't poses infinite speed? If you see everything standing still, then you should never run into anything, even though to an outside observer you would crash into something. Would you be alive or dead if you traveled at the speed of light and ran into the Earth? Everyone else would see you crashing into it, but you would see time stopped, therefore you can't travel distance over time...
  10. A single bacterium does develop a resistance, it only takes one bacterium to form a resistant colony.
  11. Ok, I'm going to take a leap and see if this works... Degenerate matter, very dense, much like boss-einstein condensates, but are the atoms in degenerate matter entangled?
  12. Well has there been any change?
  13. Aren't there many complaints by doctors of taking too much anti-biotics, since taking too many increases the likelihood of a bacterium developing a resistance? They are referring to whatever bacterium that the drug targets or whatever it effects. If the drug targets bacterium in a wound, then the bacterium in your wound might possibly develop a resistance when exposed to the drug. Most often though it will get them. Really any bacteria colony that is exposed has a chance of being resistant, but most of the time you put antibiotics inside of your body, which is often where bacterium also are, so its not likely they are talking about bacterium outside your body unless they say specifically on your skin or in the air or something.
  14. Bacteria develop resistance via evolution. There are literally millions of pounds of bacterium covering the Earth every second, one of them is bound to randomly develop a gene that will allow it to survive the drug that it is exposed to. If just that one bacterium survives, it will multiply and create a whole colony that will survive the drug and eventually spread unless contained.
  15. Hmm, ok. Well this probably off topic, but I was just asking because the history channel was exploring the possibility that aliens visited Earth in the past, a strong piece of evidence they had was that it seemed as though an atomic bomb detonated in India around 12,000 years ago, and during that time, ancient texts of hieroglyphics (not written languages) also depicted some kind of large explosion that killed and injured many people. The surrounded ground was melted into a specific type of glass that is also found at nuclear bomb testing sites in the US such as in Arizona. But, I don't buy it, so I'm trying to find another explanation, but it seems as though this meteor idea is more on the improbable side.
  16. Antimony fluorine acid and it has a pH of negative 25, I think its called fluoroantimonic acid. I think it's the current confirmed record holder http://en.wikipedia.org/wiki/Fluoroantimonic_acid , and before that I think its carborane acid with a pH of negative 21.
  17. Capsasin I think is the chemical that causes things to be spicy, but...can your body use something like that in any way? How is it helpful?
  18. Could there perhaps be a large enough meteorite that the .7% enriched part is enough to cause a reaction, or is there no way it would ever work?
  19. If I have a meteor of uranium, could it slam into the Earth with enough force to compress it and cause a nuclear explosion?
  20. Why would an omnipotent being only settle with one girl? Why does god even need the capacity to reproduce if he could just "make things"?
  21. So how do the green plants treat the purple plants? Unless god is also purple? Er wait a minute, I thought he was in human form, how could other life forms possibly be in his image in any way shape or form? We should go kill off all the green plants because we all know the existent god has the form of a human. That'll teach them to give us air to breathe.
  22. Most of your assumptions that other people's assumptions are flawed are in fact themselves flawed. Natural selection is in fact why most plants today are green, because a long time ago a chemical was randomly generated by genes which only absorbed blue and red light, and that gene has survived and spread making itself present in most plants and thus making most modern plants green.
  23. They're green because the trait of being green has survived, and other traits like black or red or blue haven't so much.
  24. Well, that does make sense too, but then why don't most reptile species have infra-red vision if it's that simple? It's not really flawed it's just that you can't do two opposite actions at once, otherwise you get 0, which obviously isn't how plants get energy. Plants "could" reflect other light and probably do, but we can't see the red past infra-red or the violet in the ultra-violet spectrum The plants on Earth happen to reflect green and usually that's the most efficient. They can absorb green, but if they absorb green they can't reflect it, and in some situations that's not efficient trait, so the trait of absorbing green doesn't survive as much. If plants were black then they would absorb too much energy, dehydrate and die, so the trait of absorbing all colors does not survive long enough for a plant with that trait to reproduce and thus modern plants are not green. Every once in a while there can be a mutation to make a black plant, but it won't survive long enough to pass that trait down and make other plants black unless its in a very unique environment. So the answer is because no previous plant that can absorb all colors has survive and passed that trait down.
