It will have been ticking before the big bang, and how did an atom get there?

Atoms didn't form until after the Big Bang. Time didn't "tick" before the Big Bang because it didn't exist. It's difficult to comprehend but there was just nothing.

How do scientists now that the Big Bang existed?

I believe that time began when God created the world!
I find it extremely hard to believe that this complicated world was created from a big bang. No offence to anyone.

Time doesn't tick, we just think it does.

What caused it all to start?

A singularity - An infinitesimally small, dense and hot concentration of matter.

I agree, I mean, its convinient how we have plants keeping the planet alive, which is surrounded by the atmosphere which protects us from the sun, the Earth has 24 hours (or whatever) which gives us enough time to sleep, we have animals which keep us alive the moon reflects the sun, so its never completley dark outside, too complcated to just "happen"

well where did that come from?

Time and space didn't exist before the singularity so it's just hypothetical. The answer is simply "nothing".

There was nothing before that.

Time itself started at the big bang.

no the big crunch was before the big bang lol

the big crunch is when the universe collapses on it self and all matter inside the universe was at one point and then the big bang happend

In other words, something. Do the scientists know how this matter was formed ?

Well it did just "happen". The chances of a planet having the conditions to support life is very small but out of the billions of stars it's inevitable that at least one will have a planet orbiting it which contains life.

well what would you say the odds were

1 in a trillion

cause there are trillions of galaxies

In physics, sometimes you just have to accept the facts. It came from nothing. And that's it. You can't comprehend nothingness cause it doesn't exist.

You cannot prove that. For a Big Crunch to occur the Universe needs to be closed and the Hubble constant needs to be geater than 1. The Hubble constant has been calculated in recent years to be less than 1 therefore an open universe situation is more likely in which it continues to expand forever.

So that means Science cant explain it
a explosion cant come from nothing
something that causes an explosion cant come from nothing

Basically it's how the wavelength of light appears to be longer from distant stars etc because they are travelling away from us.

it is a wave on the red part of the spectrum because it is in the red part of the spectrum anything that produces it (galaxy's) must be moving away and because the distant galaxies are producing it they must be moving away so if they are moving away there must have been some effect to make them move away The Big Bang

red shift also proves the universe is expanding

ahh thanks for explaining

just to scare you

when they start to see Blue shift the universe is collapsing on it self

Ah well, at least we will get some notice before hand. Or rather they will. lol
