Interesting! My question was meant to refer to an otherwise unidentifiable *piece* of bone -- and the testable characteristics that might confirm that it is human. Also -- can anyone tell me more about diet information from isotope ratios (or another method?) And one more thing. What...

At least I think that's the field I'm looking for. I need to know if there is a way, through collagen collecting, DNA testing with PCR, etc., what is the defining characteristic in a piece of a BONE that would tell that it is human, i.e., is it possible to tell the # of chromosomes, or some...

this might be a physics question, but... I don't understand something about thermodynamics. About how mass cannot be destroyed or created, really. They say that the Earth gains mass every year from meteorites, right? And more people are born every year, and grow, etc., adding mass to the...

Ok I'm not sure this is in the right forum, and this is a very broad question; I'm just starting to understand magnetism and its relation to the universe. This is basically a bunch of conjecture on my part, could you tell me if I am anywhere near the mark? The way I imagine it is this: There...

I think I understand that point. What I don't understand is why cosmologists, who use such terms, seem to think that they can explain how spacetime can expand while not expanding into anything, yet they do not do so. Isn't this terminology dependant on the idea that expansion, by definition...

hmmm ok well I guess I shouldn't expect a concise answer if my question is so...not concise. I suspect that in order to answer the question you need a few assumptions, one of which might be that the universe is finite, but expanding...in which case there would be an inertial reference frame...

Ok this is kind of a weird question...but: Assuming that something on Earth that is not moving is still in reality moving because of the planet's rotation around the sun, and assuming also that even the sun which seems to be stationary is also moving about the galaxy, and so on and so...

What's all this I hear about White holes...some kind of opposite of a black hole that emitts matter and light instead of sucking it in? Is this an actual theory or just conjecture?

So I heard a theory once that a planet, gaining mass through collisions, could over time become a feelble star (if it gained about 10x the mass of jupiter), through adding kinetic energy and pressure, etc., and that this would create nuclear ignition. My question is this: If somehow we could...

Just a simple question for people knowledgeable in biology: what are some specific examples of determining someone's age by studying their body? I know you can use bones and teeth, and perhaps hair or something, but what specifically is it that the coronor, let's say, looks for to determine...

This is interesting. If this were true, then could it be possible for there to exist an opposite of a black hole, and wouldn't that be what our universe is? (i.e. expanding as opposed to collapsing into infinity?) Also, why wouldn't the event horizon be infinitely large if the singularity had...

Ok...so what about black holes? Ok, so... If there is a star that runs out of the fuel it takes to remain stable, then depending on its mass it will either supernova, collapse into a white dwarf, or collapse into a black hole, correct? So a white dwarf is a star that has run out of fuel...

Ok... Let's say there is a star with a planet orbiting it which supports life. If, somehow (never mind how), the star within an instant became massive beyond the Chan. Limit... 1) how long would it take to form a black hole (assuming that the mass kept increasing until it reached a black hole...

wow thanks I totally appreciate the tool quote because somehow it's totally relevant. Anyway, I would love to hear what has happened to koalas (the thing about how they have lost brain mass, or whatever it was), and also, what in the world is a "morlock"? I was not necessarily...

This is a question geared toward human evolution, but I figured a biologist would be able to answer it. There are two parts: 1. If supposedly, we physically evolved (less hair, stand up straight, etc.) because we changed our behaviour, would it be safe to say that generally, as something...
