Black holes are so fascinating and mysterious. I believe fundamental particles do not die. They decay, annihilate, there is pair production and they can do other things. Photons also do not die, they can be absorbed, transfer energy and a lot of other things. When stars, planets, galaxies and other celestial objects die, fundamental particles along with photons would still exist in the universe. When we die, the atoms and particles that make us up, would be dispersed around earth or in the universe. However, some of these particles and photons could fall into black holes, where from our current understanding, matter and light is lost forever. There is a theoretical prediction of something called a photonsphere where photons orbit around a black hole until they escape out into space or fall into the black hole I think. We don't know what happens to the particles and photons that end up inside a black hole. There is Hawking Radiation that Stephen Hawking proposed but I do not know if it releases particles that were once trapped inside. There's a lot to still learn from black holes! Here is a video with Janna Levin talking about Black holes. https://lnkd.in/ec65eEGK (Big Think, Sept 2023) References: Big Think, Sept 2023 - https://lnkd.in/ec65eEGK

There are various types of black holes, each distinguished by their formation and characteristics. Stellar black holes, which are created from the collapse of massive stars, typically have a few to several tens of solar masses. Supermassive black holes, found at the centers of most galaxies including the Milky Way, have masses ranging from millions to billions of solar masses. Intermediate black holes, still largely theoretical, are proposed to have masses between those of stellar and supermassive black holes and might result from the merging of smaller black holes. Additionally, primordial black holes are theorized to have formed right after the Big Bang and could vary greatly in size. Each type of black hole differs in its size, formation method, and location within the universe. https://lnkd.in/eR2UtPzG #galaxyaerosgh #space #spaceexploration #SpaceNews

The Newton Law of gravity, The force of gravity, or gravitational force, pulls objects with mass toward each other. We often think about the force of gravity from Earth. This force is what keeps your body on the ground. But any object with mass exerts a gravitational force on all other objects with mass. For example, there is a gravitational force between you and every object around you! The gravitational force between two objects is larger when the masses of the objects are larger. That’s why you can feel the gravitational force between you and Earth, but the force between you and objects with smaller masses is too weak to feel. The gravitational force between two objects also depends on the distance between their centers. The further objects are from one another, the weaker the force is.
