Why the solar system can exist

If gravity is so attractive, why doesn't the earth just crash into the sun? Or the moon into the earth?

The answer is evolution.
All the dust that felt on the sun was not fit. The water on Mars also lost the battle against the evolution of the solar system. Earth and the other planet are the fittest of all matter that didn't make it.
The big gas giants, Jupiter, Saturn, are the elephant in the room, the real cause of disappearance of the original dust cloud. It's like looking at the bones of mammoth and saber tooth tiger and asking :What kill them"? We can not imagine any link with the invasion of humans and the extinction of so many species. -
can anyone please explain how string theory fits into this at all? 11 dimensions and such (he said it could only work in 3)

Thumbs up for cheese!

I hate cheese

"lucky" he says

thumb up for the cheese = )

This explanations are so cool!😂😂
-
I was confused about this fact before.Now problem solved.
Thank You M Physics. -
okay but what if we do live in a universe with 4 spacial dimensions but we only inhabit 3? sorta like a picture on a paper is a 2d object in a seemingly 3d space.
-
if we lived in 2d, there would be no gravity , because there's no mass.

piss swiss cheese

science. it only makes sense when you drink its piss.

But wait, if friction is the reason the balls in the funnel lose their "orbit", why don't do planets do ? Space is never actually empty and there is always molecules around, so, if our solar system was eternal, wouldn't all the planets crash into the sun at one point, taking an insanely long time ?
-
It sure doesn't feel like we're on a spinning ball! Maybe because Earth is actually FLAT and motionless. #FlatEarth do the research and join the awakening of reality.

the answer: inertia
-
gravity would actually be weaker in 4d because there will be inverse cube law
-
Please explain why 2D and 4D orbits can't exist! Also, this might be cheating but couldn't you make a stable orbit in 4D space by only using 3D objects and trajectories?

The cheese and dimensions part of the video are only distractions to keep people from critically thinking about the main subject of the video.
-
This does not make sense to me. I will give you an example of what I am thinking
The moon orbits the earth and the earth orbits the sun. Since the suns gravity is two times
stronger than the earth (because the distance) the suns gravity should pull the moon away from the earth. -
cheese?
