2) Footprints on the moon will remain there forever
Those footprints ain’t gonna disappear.
The moon essentially has no atmosphere, which means there is no water to wash the footprints away nor is there wind to tear away the surface. The traces of the Apollo exploration will be around for ten to 100 million years until the rocks eventually erode at a rate of approximately 0.04 inches every one million years. That’s in scientific terms, but in human terms, it’s practically forever lah.
3) You are actually not alone
The Milky Way.
We’re not talking about aliens. There are over 100 billion stars in our galaxy, the Milky Way, alone. In the observable universe (in theory, what can be seen from Earth), there is an estimated total of 70 billion stars. In other words, there are more stars in the universe than grains of sand on every single beach on the face of the Earth. Yup, let that sink in a little bit.
