"How dense is the center of the Sun?" Turns out, pretty frakking dense. Also, the Sun makes a VAST amount of energy there, and I go through a few analogies to help make this make sense. No marshmallows were hurt in the making of this video.

Wait, a helium atom isn't four hydrogen atoms, is it? Isn't it two hydrogen atoms and two neutrons?

Pjalne, that's correct. That's why I said "it's more complicated than this" in the video. :-) There are several steps involved in getting the hydrogen atoms to make a helium atom. You can look for it on Google; there are lots of sites explaining it.

It's actually my home office, but it doubles as a guest room. But of course you're correct anyway. :-)

Minor technical point. The 150 grams of sun stuff at the center do not "weigh" anything. :)

I'm an American and that eye roll was hilarious! I'm also a little sad that most Americans watching would probably need that conversion :P

Frakking? ... Do I smell some battlestar galactica over there? :)

Earth's sun is a planet's core that's evolving. It consists of gigantic spherical magnets that are inundated by a sea of ions in a plasmatic state. It will go through some osmotic metamorphic changes before it accelerates its architectural evolution and becomes a world as we know them.
When brown spots start to appear on its surface its because it has began to develop a skin. The skin will be made up of magnetite which will serve as a medium to support the substratum where the crust will rest.

There are a total of 4 protons and 4 electrons in the ingredients to fuse a helium atom. There's an interesting property of protons and electrons, where they can combine (i know, it's a bit more complicated than that, but for the sake of simplicity...) to form a neutron. So if you add all 4 protons together in the nucleus, and then add to 2 of them an electron each, you end up with a nucleus of 2 protons, 2 neutrons, surrounded by the remaining 2 electrons. Hope this helped!
