Matter and radiation don't make up 'space', they exist within it. A simple definition of universe is, per wikipedia: all of space and time and their contents. Matter and radiation make up the universe in the same way that marbles in a jar make up a jar of marbles.

It does. Magnetic interactions are EXTREMELY well understood and accurately predicted using Maxwell's equations or their counterparts in Quantum Electrodynamics. Most of your claims are simply wrong. Nothing is hidden. Mathematically construct an appropriate scenario and apply the laws of...

I believe I found one: But seriously, rest in peace, Paul. You will be missed.

I am saddened immensely by this news. Phinds and I both joined within a few months of each other and he was one of my favorite and most memorable members of this forum for the last 15 years. He will be missed greatly.

Note that some formatting was lost in the quote above. The mass of the galaxy is about 108 solar masses, not 108.

Per wiki: A meteorite is a rock that originated in outer space and has fallen to the surface of a planet or moon.

Drano already has bleach in it, so it should be safe. The main two ingredients in Drano are: Sodium Hydroxide - The strong base that eats up the clog. Sodium Hypochlorite - bleach, which apparently bleaches organic matter and provides more 'cleaning power'.

I guess my question on this topic would be, what determines the orientation of the orbitals in an atom/molecule? Does the nucleus have anything to do with it?

Indeed, it is WHY the number is so big that is interesting.

And the observable universe is about 8.8x10^23 km in diameter.

This is an internet forum for learning about science. The vast majority of members here, including myself, are not scientists, so you are addressing the wrong crowd. And doing it poorly. Please see the links below, which show multiple methods that do not depend on measuring the thermal emission...

Thread locked for moderation.

If you're suggesting that the plasma inside a reactor is emitting the same amount of radiation as a solid blackbody at the same temperature and size, then you are very wrong. A very, very thin and sparse medium at temp T will obviously emit less radiation than, say, a blackbody at that same temp...

Seeing as we've achieved 500 million C and higher your statement is obviously nonsense. Unless, of course, everyone involved in plasma research and fusion energy is outright lying. But I doubt it.

There are always transportation costs. Either the fully/partially assembled spacecraft and launch vehicle, or the materials to build it. But I agree with the spirit of what you're getting at in that if the launch technology favors high alititude vs low altitude launches then transportation costs...
