Matter was created by a mishap when particles appeared in different counts. When this happened it caused a chain reaction what we see today. All material that exists was started by particles. Once particles appeared it became a gas form which was probably hydrogen. Part of the hot gas started to clump together witch created stars and galaxies.
When a supernova happens from a large star it creates lots of different material like gold, nickel and iron. The hardest material in our Universe is a Neutron Star which comes from a supernova also. A Neutron Star will eventually turn into a black hole which that hard material (iron) in a Neutron Star breaks down back to moving particles in a circumference. All black holes is dieing matter So there is limitation on how hard matter can be. Eventually all black holes in our Universe will shrink to nothing. They will be the last ones to go before the "Big Rip". Inflation is caused by a negative vacuum outside our Universe. Infinity has a constant negative energy. Galaxy's have a positive pull gravity. This is what's keeping our Universe in check but eventually eternity (negative energy vacuum) will win.
My puzzle got completed on June 21, 2020 on the understanding the big picture of the Universe. All this learning I achieved was research mostly on YouTube. This took years to learn. This all got started when I heard Sephen Hawking talking on WIBC about nothing becomes something in 2012 at work. My theory is there has to be something to make something. Eternity always had energy.
