"The knowledge that the atoms that comprise life on earth - the atoms that make up the human body, are traceable to the crucibles that cooked light elements into heavy elements in their core under extreme temperatures and pressures. These stars- the high mass ones among them- went unstable in their later years- they collapsed and then exploded- scattering their enriched guts across the galaxy- guts made of carbon, nitrogen, oxygen, and all the fundamental ingredients of life itself. These ingredients become part of gas clouds that condense, collapse, form the next generation of solar systems- stars with orbiting planets. And those planets now have the ingredients for life itself. So that when I look up at the night sky, and I know that yes we are part of this universe, we are in this universe, but perhaps more important than both of those facts is that the universe is in us. When I reflect on that fact, I look up- many people feel small, cause their small and the universe is big. But I feel big because my atoms came from those stars."
- carlsagat 3y agoThis is the most beautiful explanation that I've heard for a long time (:

- layer8 3y agoThose feelings themselves are just patterns formed by particles in the brain, though.
- dotancohen 3y agoPossibly not the same particles, though. Baryonic matter condenses and undergoes nuclear transformations in the stars. But if our feelings and memories are electrical phenomenon then they were not formed in stars.
- layer8 3y agoObviously, the patterns weren’t formed in stars. My point is, if you are admiring the body being a pattern formed of particles coming from the stars, realize that the admiration is itself also just such a pattern (as is that realization).
- smegger001 3y agoFrom a certain point of veiw we are nothing but a 3d cellular automata made of subatomic particles in a most extensive run of conways game of life.

- agravier 3y agoI think electrical activity in the brain is misunderstood. These electrical signals are not electrons moving along a wire, they are waves of depolarisation between the inside and inside of the cell membrane travelling along the axon or dendrites. The depolarisation is due to the activity of a bunch of ion pumps and channels that let ions pass between the inside and outside of the cell. Some of these ion channels are themselves voltage-gated, thereby further increasing the depolarisation in response to depolarisation, and propagating the signal that way. So it's still mostly atoms moving in and out of cells. Still stardust.

- adidum 3y agoAnd this can be taken a little further. That we humans are the only part of the universe, as far as we can tell at least, to be aware of all this. We are the part of the universe that allows it to look back at itself. If the universe is a body, we are the eyes of that body. Generally speaking of course. But I find this very empowering as a human being.
