But I thought a Helium can't combine with another Helium atom because the result would be too unstable. If a Helium(2 protons/2neutrons) combines with a Helium you have 8 particles... but atoms with 5 or 8 particles are unstable.
That's why I wanted to know what role deuterium plays in this...
Would someone mind (in simple terms if possible) explaining how at the beginning of the universe Hydrogen combined to give Helium; then then how Helium combined with deuterium to create the heavier elements?
I would just like to be more versed on this process...
Thanks for any help!
Okay...
Let's see if I'm catching on.
A piece of iron heated to a very high temperature so that it would start to glow (giving off whitish/blue'ish light) would be an example of a blackbody. It doesn't reflect light that would shine upon it, but it does emit the heat that it absorbs.
If...
Hello,
New to this message board (and very happy to have found it).
I am reading a book on cosmology by Steven Weinberg... I am having a terrible time understanding what exactly black body radiation is. Could someone please describe it in the most accesible terms? Also, if you would please...
