Does it mean, if you don't understand something, and the community of physicists don't understand it, that means God did it? Is that how you want to play this game? Because if it is, here's a list of things in the past that the physicists at the time didn't understand [and now we do understand] [...]. If that's how you want to invoke your evidence for God, then God is an ever-receding pocket of scientific ignorance that's getting smaller and smaller and smaller as time moves on - so just be ready for that to happen, if that's how you want to come at the problem

Once you've got the makings of a star, gravity draws leftover gas and dust into a giant swirling disk. The dust continues to stick together, clumping into rocky asteroids, which eventually become orbiting rocky planets. And voila: a solar system!

Part of knowing how to think is knowing how the laws of nature shape the world around us. Without that knowledge, without that capacity to think, you can easily become a victim of people who seek to take advantage of you.

I think everyone should have a personal mission to leave the Earth a better place for them having lived in it and let Earth then take it from there.

While the Copernican principle comes with no guarantees that it will forever guide us to cosmic truths, it's worked quite well so far: not only is Earth not in the center of the solar system, but the solar system is not in the center of the Milky Way galaxy, the Milky Way galaxy is not in the center of the universe, and it may come to pass that our universe is just one of many that comprise a multiverse. And in case you're one of those people who thinks that the edge may be a special place, we are not at the edge of anything either.

We are part of this universe; we are in this universe, but perhaps more important than both of those facts, is that the universe is in us.

Space enthusiasts are the most susceptible demographic to delusion that I have ever seen.
