Comments by "michael" (@michaeld4861) on "How Gravity Actually Works" video.
You never explained how the Earth can be accelerating in every direction at the same time and yet still remain the same size. Also, why does space time curve around object with large mass then if not for gravity? And why does Earth have an atmosphere? Why is everything drawn towards the mass of earth?

@Jonereator2 Size doesn't effect gravitational pull, only mass. You could have a cotton ball twice the size of the earth but it still wont have the same gravitational pull.

because gravity is dependent on mass, that's why planets rotate around the sun, or each other, and a ball of cotton does not rotate around a leaf. Gravity is the weakest of the 4 forces, nuclear and electromagnetic forces are stronger hence why you only observe gravity on extremely large (high mass) objects like planets. electromagnetic force has poles because it has a positive and negative. Gravity does not, it only attracts.

@k0nk0n Thanks, I didn't catch the different definition used for acceleration. That totally changes everything. lol

@tf1639 Even if Earth expends energy with the force of gravity, that energy would take almost forever to run out seeing as how gravity is the weakest force. I mean even the sun literally burning gas takes billions or trillions of years to run out of fuel and that's expending Way more energy than gravity.

@rtensor That sounds like an excellent analogy, but I still don't see how it proves that gravity doesn't exist.? Gravity is an incredibly weak force after all.

@onemadscientist7305 You do a great job explaining things. I can't help notice you said "because the mass of the rest of the cloud curves spacetime" which I'm taking as the effect of gravity, correct? why would mass bend space time if not because of the effect of gravity?
