comment Presence of planets in Milky Way and other galaxies
I never understood the fascination with existence of planets outside the solar system. Isn't it common sense that any matter that doesn't turn into a star will turn into something else? And clearly if it's large enough it'd be a planet...

comment Why does a star beyond a certain mass limit (Chandrasekhar limit) only become a black hole?
So that means all the iron on Earth came from supernova event(s) from a star with mass $M_\star\gtrsim 8M_\odot$, right?

I feel it's a science vs. engineering thing?

comment When a planet has a high gravity, is it impossible to build and launch a successful chemical rocket to space?
True, good point!

I haven't really tried to work it out, but does this take into account that the mass must come from within the planet itself?

comment Why does a ball bounce lower?
@Cruncher: I don't think the OP is asking whether it's true, I think the OP is asking why it's true.

comment Why is it said that without quantum mechanics we would not have modern computers?
"chip designs have reached the point of even needing to foresee the Casimir effect" Do you happen to have a link that explains this need?

comment If temperature is average KE per particle, and heat is total KE of all the particles, how can molar heat capacity vary?
I'm slightly confused about something else entirely. Average kinetic energy per mode would be in units of Joules/mode or whatever. Temperature is Kelvin, so how can you even claim they're the same?
