Lemaître was an astronomer and professor of physics who is thought to be the first to have theorised that the universe is expanding.

His theory was observationally confirmed soon afterwards by Edwin Hubble in what is now known as Hubble’s Law. Lemaître is also credited with proposing what has now become known as the Big Bang theory – which says that the observable universe began with an explosion of a single particle.

Do you think he was correct about BBT?

I find theories quite odd. It is someone telling us they are unsure yet so many believe them with 100% certainty.

Not quite. A scientific theory is someone telling us they are pretty damn certain about something and providing evidence for it. Therefore it is reasonable to believe it.

Theories in science doesn't mean "dunno, maybe this?". A theory is a well tested hypothesis repeatedly verified experimentally.

As per the other replies, you are misunderstanding the definition of a scientific theory. I think you might be confusing it with an hypothesis or a conjecture.

I was once told that Muslims believe in the theory as they believe it was mentioned in the Quran. As for Christians, I think many also accept the theory. I think because the theory doesn't clash too much with religion lots of people believe in it.

I will. They can't both have been matter or else there would be no antimatter, they can't have both been antimatter because there would be no matter and they couldn't have been 1 matter 1 antimatter because they would annihilate

actually there were three...

1 x matter

1 x antimatter

1 x special matter

the last one prevents the other two annihilating the **** out of each other

it also had all the mass at the start but gradually shared the mass out to the others once they had separated and multiplied.

Ah okay.
It wouldn't have necessarily needed all the mass though, mass could be made from photons
