It can take a photon formed in the heart of our sun over one million years to reach the suns surface and escape, and only eight minutes to reach earth once it does.
Over one billion neutrinos pass through your thumb nail every second.
The largest black hole discovered so far is more than forty billion times the mass of our sun.
@Zaphod42 So when you cast a shadow with your body, you stop many photons from hitting the earth only a few feet from its destination after a journey of a million years. How cruel!
@NerdyPotato Think of it from the photons position! They move at the speed of light, and time stands perfectly still at that speed. So from their perspective the moment of creation and the moment of death are the same moment!
