Light is Pure Energy! 🤯 w/ Neil deGrasse Tyson

Cosmos Calculated•1:28

Transcription

We live in a world that's actually uncommon for what goes on routinely in the universe. If you go to the center of the sun, for example, I don't recommend this, but if if you went to the center of the sun, you would find that the light that is passing your head, it's primarily X-rays. There's other light, too, but it's dominated by X-rays.

[music]

X-rays is just another band of light. Isaac Newton didn't know that. He didn't know everything. All right, the whole spectrum. We have Roy G. biv on the other side of the V, we have ultraviolet, invisible to our eyes. Beyond beyond ultraviolet, you have X-rays and that we can't detect those either. Uh, and then gamma rays. Go to the other side of red, we find infrared. Can't see that either. Uh, beyond that, we have microwaves and then radio waves. All of it is light. It all travels at the speed of light.

So, if you go into the sun, here are these X-rays. They have such energy. is a photons of light. They have so much energy. Energy goes up with violet, ultraviolet, x-rays, gamma rays goes up. It goes down in the other direction. Has so much energy. You know what you find out? It has so much energy. It could spontaneously make [music] matter. It can make a pair of electrons on its own. So in the center of the sun, matter is being forged out of the soup of energy every moment of the sun's
