When a massive object travels through space distorting its geometry, does the space gradually revert to its previous state, or does it oscillate back and forth eventually settling into its state as it was before it was distorted by the massive object ? If the fabric of of space has a high...

when a star goes supernova, does it eject out earth, mercury and mars sized chunks. Surely the asteroids that are even the size of Texas won't have enough gravity to compact hard enough to become one chunk. What is the current belief on how large of chunks are ejected from a supernova. Thanks

Not sure, maybe PBS SPACETIME. But I have seen multiple explanations of gravity that has space moving into massive objects, usually black holes. This movement of space into a massive object is usually given to be the explanation of how gravity works.

Many explanations out there for gravity. One that I saw a few months ago explained that our gravity hete on earth is space moving toward the center of the earth, and we should be falling to the center of earth at a rate of 9.8 m/ s/s. But the surface of the earth is in the way... What happens to...

Is red shifting of light from distant stars actually caused from them moving away from us, or is this a simplification. Doesn't this break the rule of light always going the same speed. Could the light rays be possibly lengthened because when the light left many yrs ago space was smaller, now it...

How can a particle created just outside the event horizon with no velocity (?) escape a black hole, never to return, when black holes gravity is so strong that they can pull matter away from stars many kilometers distant?

Yes, the arbitrary explosion graphics. The big bang would have looked like nothing as it happened before the formation of photons (?)

In the beginning of the universe, the hot matter of the entire universe was confined to a small volume. I would guess that compared to our time frame, time flowed slower than it does now. I would also guess that time has gradually slowed down since then. Is this significant in predicting the...

When watching a video of an explanation of Einstein's theory of General Relativity, you will see a star or planet distorting the fabric of space. This is always a 2 dimensional plane oriented in the x-axis that gets "dished" by the larger star or planet and the satelite will then roll around...

Hi DaveC, Yes, solar covers cost big bucks.. A good one for my pool is ~120 bucks, and they wear out in 3 years. My plan would cost about $60 bucks, last longer, be much easier to get into and out of a pool, be much (much) easier to clean, will fold up smaller, last longer, and take a couple of...

I didn't calculate anything to come up with the 6" depth. It just happens that in my design, 4 - 6 inches will be easy and cheap to attain. But thanks,DaveC42..., This is one of the reasons I am asking here. Wheather the air "pillow" is 1 mm, or 6 inches won't affect either the insulation...

Hi, I have some thoughts about making a much better pool solar cover. My thoughts are to maximize the temperature increase. I plan to suspend a plastic film 6 inches above the surface of the pool water creating a green house effect. Normally, very small plastic are pockets are embedded in the...

If, when the universe was young, and you had all of today's universe worth of matter compacted into a space only a few thousand/ million light years in diameter the gravitational effect on time would be much stronger than it is today. Does this affect our calculations on how old the universe is...

Looking at the huge clumps of higher elements (carbon silicon iron etc) present in our solar system, it seams as though only a few tens of billions of years would not be enough time to make all of the higher elements in the quantities we see today with stars like our sun that last billions of...

Sorry in advance for this probably stupid question. If there is entanglement is there not entaglement for all particles. If so, could there not be entanglement for the Higgs boson, and therefore our own gravity, could have an equal and opposite force, both combining for a net effect of...
