The “God particle” is a particle that is believed to give mass to matter. It is also known as Higgs Bosen. Some scientists believe that without the Higgs Bosen matter would not have mass. Some also believe it isn’t what they think it is.
Steven Hawkings thinks the God Particle could end the universe in one day. Some scientists also believe that the God Particle could have destroyed the universe just after the Big Bang but gravity saved it.
Some people believe that the Big Bang theory doesn’t make sense because what caused the Big Bang, what caused that, and what caused that etc. There is a new theory that the universe was always here. It is the only way that general relativity and quantum physics can work together.
