Reply to comment by Rodot in Bizarre star may have a solid surface, according to X-ray observations. Astronomers have now spotted a super strange one that seems to have a solid surface. Its intense magnetic field is strong enough to overcome its blistering temperatures and “freeze” its outer layers into a solid crust. by MistWeaver80

They just poof into existence? I'm assuming I just don't understand what a photon actually is.

Think of a photon as similar to a musical note when you play an instrument. For a string instrument, you pluck the string and it causes it to vibrate at a specific frequency depending on the length (i.e. it's boundary conditions). This is kind of like a photon but instead of plucking a string you are "plucking" the electromagnetic field and it makes a vibration at a certain frequency depending on the boundary conditions (electrons, ions, etc) of the system.

I understand sound to be the consecutive vibration of atoms which is why sound cannot traverse a vacuum. For light to traverse space is my understanding that is that photos are some kind of discrete particle with mass and that's why things like solar sails work.

From what you're saying, the interaction of the fields creates photons. Is this energy converting into matter and the genesis of a discrete particle?

Photons do not have mass. They do carry momentum though.

Man I feel dumb. What is a photon made of then? It's just energy that flows and glows until it dissipates? Thanks for humoring my ignorance!

Photons are made of photons. They are fundamental particles
