It is the theory that leading explanation about how the universe began.at its simplest,it says the universe as we know it started with a small singularity, then inflated over the next 13.8billion years to the cosmos that we know today.
thanks...I hope it helps you.if it helps you mark me as brainelist☺☺☺☺

The big bang theory is a cosmological model for the explanation of the beginning of the universe.
According to the big bang theory, the universe started with a homogeneous initial singularity some 13.8 billion years ago (relative to our reference frame, not absolute), which underwent a period of inflation(expansion of space in itself), and with all the epochs, formed what we see today, the universe - matter and all
So, here's the explanation:
Nearly 14 billion years ago, there was nothing but an infinitely hot, dense initial but smooth singularity (singularity because the physical laws there were different, which we can't predict). From that point, within a tiny fraction of second, I guess 10^-32 or something of a second (I will google and edit this if wrong), the inflation era took over and space expanded drastically, time came into existence. Soon after the energy of the space gave birth to quantum fluctuations, particles and their counterparts-antiparticles, got produced in pair production, annihilated and photons came into existence. The two of the fundamental forces separated out, and eventually the other two nuclear too. Some strange thing happened at this point, somehow we retained more particles than antiparticles, like many millions for one. Particles clumped, so did dark matter, gravity worked, quarks were born, and then neutron and proton. Soon after leptons, electrons and neutrinos, came into existence, Hydrogen atom was formed, the universe was cooling down now, nuclear fusion took place and Hydrogen fused into Helium, Lithium and so forth. Gravity and the appropriate temperature helped matter to clump together and celestial bodies came into existence. And you might be knowing the rest, I assume. (The fact that universe is expanding too with acceleration, faster than the speed of light)
To a geek: Buddy, I haven't rechecked the heck I am writing, so I would be glad if ya pointed out a mistake
P.S. The big bang theory is an American sitcom too #Sheldor
To rest of the audience,
Thanks
