A three minute video...But if there was a beginning, how does your science and second laws of whatevers explain what happened before that beginning?
or if you prefer... Inflation Theory, the First Law of Thermodynamics and quantum mechanics tells us that it is possible for matter to have a beginning. In a closed universe the gravitational energy which is always negative exactly compensates the positive energy of matter. So the energy of a closed universe is always zero. So nothing prevents this universe from being spontaneously created. Because the net energy is always zero. The positive energy of matter is balanced by the negative energy of the gravity of that matter which is the space time curvature of that matter. There is no conservation law that prevents the formation of such a universe. In quantum mechanics if something is not forbidden by conservation laws, then it necessarily happens with some non-zero probability. So a closed universe can spontaneously appear - through the laws of quantum mechanics - out of nothing. And in fact there is an elegant mathematical description which describes this process and shows that a tiny closed universe having very high energy can spontaneously pop into existence and immediately start to expand and cool. In this description, the same laws which describes the evolution of the universe describes the creation of the universe which means the laws of nature were in place before the creation of space and time.
That's all very well, Ding.
It depends on your favourite scientist of the day.
No. Not really. You have a better explanation? We know there was a beginning. Why does this disturb you?
