If it's nothing but space then shouldn't there be an always has been situation on the size of space? Maybe the expansion is just because matter and things hasn't always been around?

    @@ScienceAsylum Btw I just realized. Tidal forces can also be thought of as a tug of war between the gravity of the planet and the gravity of the satellite. Wait, I'm pretty sure you said something similar in your video on Lagrange points. An object halfway (gravitationally) between the moon and the earth would be equally pulled in both directions and thus remain motionless. It's the same pattern. Except that the object is well, the part of the moon closest to the planet. It's being pulled in two opposite directions: upward toward the planet and downward toward the moon. I was wondering about this apparent contradiction regarding how gravity can tear things apart when it's only attractive. Turns out, when you have different centers of gravity (pun intended), you can get ripped apart if you get caught in the middle. This also explains why once the moon disintegrates into rings, it becomes stable. The orbiting particles no longer have self-gravity and thus there is nothing to oppose the gravitational pull of the planet. Hmm but wait. If self-gravity is the cause of tidal force, then how can people get spaghettified near black holes? People aren't held together by their own gravity 🤔

    There could be several reasons. Most of Saturn's rings are outside their Roche limit, but Saturn has those Shepherd moons to help keep things in place. Also, collisions can cause rings. It doesn't have be tidal disruption (like with Phobos). So it's possible a couple large rocks collided near Quaoar and we just happened to catch the rings while they're still there.

    Loved this and it’s a good explanation, but didn’t get into what happens if the body passes quickly through the Roche limit such as an asteroid with an orbital trajectory intercepting Earth. In this scenario it may not break up, and even if it slightly disintegrated, all of the mass would still smash into Earth. As another example, let’s say a huge asteroid collided with the moon with enough force and the perfect angle so as to stop the moon from orbiting Earth. So if the moon was stationary with respect to Earth and started falling into the gravity well of Earth, would it break up? I mean, it wouldn’t matter because we’d still die but I do wonder… 🤔

    In physics, it's often important to keep "internal" and "external" separate. Only _internal_ energy contributes to the rest mass of an object. The motion of the entire object is relative to an _external_ reference, so it doesn't count.

    I think people picture moons as being solid chunks of rock that you could throw at something and have them not break apart, like a small piece of granite. It's much more realistic to see moons as collections of small rocks and dirt that are only held together in the first place by self-gravity. After all, that's what the surface of the Earth is in most places. There's nothing keeping dirt, sand, hills, mountains, oceans, etc. on the ground, except that they're heavy and the Earth has self-gravity.

    i have a question. consider a system of 2 equal but opposite charges, there are no other forces on them , exept their electric attraction. Now if we do work on the charges and separate them , the work we have done on them will be stored as P.E and when released the P.E turns into K.E and they both come together, right. now consider if the both charges appeared out of nothing (i know matter cannot be made out of nothing , but hypothetically say it did) would they still be attracted , cause we haven't done any work on them to turn into K.E. so is there a electric field in there. does that mean for any parcticle that already existed wont interact with it?

    You can make arguments about your thought experiment, though. A hydrogen atom has _less_ mass than the proton and electron separated. So two separated charges have different energy than two charges close together. If you are creating these charges together they will have a different energy than if you created them separately. You are going to have to provide that energy when you create the charges and that energy will turn into the potential between them. You are doing the work when you create the charges.

    Great Video! Just wanted to add that rings don’t necessarily have to form from mass being within the Roche limit. Take the E-ring of Saturn for example. This ring is made by a moon of Saturn, Enceladus, spewing large amounts of water from its geysers on the south pole into space. This creates a ring only visible when backlit by the sun, it is however still a ring, and a pretty big one at that! Quaoar, the briefly mentioned dwarf planet, has it’s rings well outside of it’s Roche limit, meaning the cause of the rings cant be explained with the Roche limit. The formation of the rings are still being disputed!

    That's true. If impact happens quickly, it won't have time to break apart. That's why we discuss this in terms of moons or "satellites" instead of objects more broadly. Decaying orbits are slow.

    I can you clarify what you explained on 4:21. You say when there is no gravity on the moon, the rock will drift towards mars. But don't you als o have to take the centrifugal force into account? Because even when a couple of rocks with n are close to a planet but have a velocity thats perpendicular to the gravitational force they can stay in stable orbit even if nothing holds them together because of the centrifugal force.

    Also, imagine the utterly unfathomable - in potential span and chaos - clusterf- of ancient mythology. The Sun, Moon and "Seven Stars" (or however many was in which mythical 'consciousness' at which point in time) is quite manageable (in and even without comparison) and likely less terror inducing than uncountable swarm of nearby space rocks. Quite entertaining to think how the ancients would have handled this, but I suspect that what actually happened is a more preferable scenario in this aspect as well.

I know conservation of energy is a fundamental law, but if the majority of a proton/neutron's mass comes from the movement of the 3 quarks, then this mass should cease to exists when the quarks enter the singularity of a black hole. The mass does obviously not disappear, but can u explain why?
