Causality goes out the window in quantum mechanics, it doesn't follow the rules Einstein thought it should. In fact future events can effect the past, in retro causality.<quoted text>
No, it is not known that no cause is required.
That's why physicists search for it.
One theory is the Higgs particle was the cause.
Watch as Miichio Kaku contradicts you. Notice the term "cause", and notice the phrase "before the Big Bang".
The Spark That Caused the Big Bang
"There's a reason the newly discovered Higgs boson is called the 'God particle.' It started it all."

"To put it another way, what was the match that set off the initial cosmic explosion? What put the "bang" in the Big Bang? In quantum physics, it was a Higgs-like particle that sparked the cosmic explosion".
"The latest thinking is that, just before the Big Bang, the universe was very tiny but also perfectly symmetrical. All the masses of the particles were the same, i.e. zero. But the presence of Higgs-like particles shattered this perfect symmetry. Once the symmetry was broken, the particles were free to assume the various masses we see today."
You are also wrong about quantum science. Cause is required there, same as all other science, just like Kaku illustrates.
But cause does not require time, causality does , it is the inherit nature of cause and effect and does require time. But you jumped on Michio's boat too soon , if you will notice what you copied was Higgs-like particles, and there are presumed to be other ones than the Higgs itself. But you are very wrong about why it was named the god particle.
It was dubbed "The god damned particle" because all the time money and effort that went into finding it. Goddamned was shorted to the acceptable god particle.
