There was no "before" the beginning of our universe, because once upon a time there was no time.

There are only certain intervals of time when life of any sort is possible in an expanding universe and we can practise astronomy only during that habitable time interval in cosmic history.

We can never know the origins of the universe. The deepest secrets are the ones that keep themselves.

If all the stars and galaxies in the universe today were smoothed out into a uniform sea of atoms, there would only be about one atom in every cubic meter of space.

Once upon a time there was no Time.
