The Universe, in perspective.
- There are between 200-400 million stars in our galaxy.
- There are between 400 billion to a trillion observable galaxies, and we discover new ones every day.
- This means there are 400,000,000,000,000,000,000,000 stars in the observable universe, according to the higher estimates.
- This is merely the observable universe, which due to the expansion of space and the speed of light, is only a tiny fraction of the greater expanse. Even ignoring the fact that space is infinite (matter and energy are not, however), what we see only accounts for a tiny part of a much greater whole.
- This ultimately rounds out to the fact that the universe is a pretty big place.
Though, when the aliens invade, this might lose some of its impact.
