What are the odds?

UniverseNot to state the obvious, but Earth is one planet, orbiting one star.

This may also seem obvious, but the Sun is not the only star. The Milky Way galaxy alone contains about 300 billion stars. If that’s correct, it means that the odds of Earth being the only planet in this galaxy with life on it are 300,000,000,000 to 1.

And the Milky Way isn’t the only galaxy. The information we have now places the estimated number of galaxies in the universe as high as 500 billion. In other words, for every star in the Milky Way, there could be another entire galaxy.

Obviously, this changes the odds. If both of the above are true, that means that (assuming my math is correct, it was never my best subject) the odds of Earth being the only planet with life are now 150,000,000,000,000,000,000,000 to 1.

Pretty lopsided odds, yes?

So do I think there is life on other planets?

No. I don’t think there is.

I know there is.

There’s no dreaming involved in this one.
