It's something that is absolutely mind blowing.
A few facts which I think I have posted before.
There are 100, 000 million stars in our galaxy alone and there are at least 100,000 million other galaxies. If the stars in our galaxy were grains of salt they would fill an Olympic swimming pool and if the stars in the universe were grains of sand they would fill every beach on earth.
If you travelled from one end of our galaxy to the other at the speed of light it would take 100,000 years.
I would assume that there is a chance of there being thousands of millions of other universes as well.
It could be that there is no beginning or end to anything. We have been taught to think logically, but this could be way out of our understanding.

Anyway, how important does your life and job seem now?🙂
