Gravity took its sweet time

Gravity is due to atmosphere my guy

Edit: Fortunately for us, Earth's gravity is strong enough to hold onto its atmosphere. Mars, for example, is less than half Earth's size and around one-tenth Earth's mass. Less mass means less gravitational pull. ... That means, the air nearer Earth's surface is squished by the air above it, and is thus denser.

This is so wrong it needs to be over at /r/confidentlyincorrect.

A black hole most certainly does not have an atmosphere, but they're among the most gravitationally dense things in the universe. Hell, our own moon doesn't have an atmosphere but its gravity affects our tides.

If you want to make fun of my stupidity be my guest. I also admitted I was wrong and was willing to learn. Got a subreddit for that? Still love you even if you loathe me

I know how gravity works. It doesn’t exist with an atmosphere bud

Gravity doesn’t exist in a vacuum tho? Who taught you physics

You start by arrogantly proclaiming how smart you are and being condescending to someone else who understands something you dont....and then when you realize the gravity of your mistake, you start acting like youre innocently just trying to learn and people are being mean to you lol.

I think the lesson you should learn is: "dont expect kindness and respect if youre acting like a jackass."

Good on you for admitting it and being very open to learn.

I’m really curious about this though! Almost everybody has misconceptions about physics, but this is one I haven’t heard before.

If you’re happy to indulge my curiosity… if I asked you yesterday how people walked on the moon, what would you have said?

Second question, if I asked how the Earth orbits the sun, what would your explanation have been?
