How the universe was created, the widely accepted theory is Big Bang theory. Around 13.8 billion years ago from a single atom which was so so dense, that we can't even think of it, suddenly began to expand. The energy created itself forms gluons, and they form quarks and then quarks begin to form new particles like proton, neutrons etc. And then these atoms and molecules begin to form billions of stars and galaxies. Something like this and so many other causes and things happen too but let not go into details cause it's another broad topic to discuss. But just think for a moment what was there before the Big Bang , how this single dense atom or whatever created, how it came into existence and why that bang occurs and how it formed. If there was nothing at that time how it came into existence and so on. Phewww thats a lot of wierd questions with no any fix answers, right..? Is there something mysterious energy or particle or force which governs this
