Asking big questions about the universe



How did we get here ?

Big Bang was the start of universe

BUT THE BIGEST QUESTION IS

What existed before the Big Bang

We know very well that universe created in different stages


Are we alone?

We don’t know how life first appeared

3 billion years ago we don’t know how earth like


We will survive?

If we are the only existence in this universe, we will survive.
