I'm really enjoying the Amy Farrah videos..... That's how I will always remember her as Amy didn't know she had a real PHD
lol lol amy farrah fowler aka blossom russo
Also holds a real life degree in neuroscience. Her YouTube channel is quite interesting
Interesting Scientific speculation as to what happened way in the past.
^ It does help explain the oddities with Uranus' axial tilt.

Synthetic rotation brings black hole energy theory into lab, amplifying waves
More than half a century ago, Sir Roger Penrose envisioned a scenario in which energy could be extracted from a black hole spinning at extreme speeds. He proposed that a particle entering its ergosphere—a region of space dragged around by a rotating black hole—could split into two. One part...

This rotational energy is interesting because there is directionality to the rotating system. That means, the gravitational waves move, at different moments in their passing, both with the direction of rotation, and against the direction of rotation. That is not a symmetrical system.On siphoning energy from black holes—a model?

In this video about gravitational memory,
the lecturer mentions ocean waves and how one would expect the person floating on the surface to be displaced by a passing wave, then return to their exact position from before. However, it doesn't work like that because ocean waves act in a uni-directional energy system. Gravity acts upon the floating object to move its position from the start point so it can't return to its original position after the wave passes.
Given that a transverse wave moves in one direction, and gravity accelerates in a perpendicular direction, the floating object, when lifted on the incline of the oncoming wave, will "surf" on that leading face because of gravity, causing it to remain with the wave for longer than the medium that makes up the wave would dictate. Then, after the wave passes, the floating object surfs down the back slope of the wave, ideally, to return to its original position, except... . Because the wave is moving in one direction, the surfing on the front face lasts a lot longer than the surfing on the back face.
In essence, the floating object remains is on the leading slope longer than the medium of the wave takes to lift, and less time on the back slope than it takes the medium of the wave to fall. Thus, directional movement of the wave and gravity conspire to produce a "memory" in the system.

Which might help “swimming” in spacetime
I am hoping Planet 9 is a Neptune-mass black-hole….that could really be useful.

imagine if there are tons of different planets in our solar system and at the same time also many different planets near earth and the moon but they are hidden
Their gravity would cause effects on Earth at some point
after what i saw on season 4 episode 1 of star trek strange new worlds
now i wonder if that was what really happened 100 million years ago

I would not want to be in it's path of travel or anywhere near it.
It would make for one hell of a gravity assist

@Will The Serious thought you might find some fun with this
The most famous time machine if you will....
And a random thought with our galaxy and universe being several billion years old it's not that we can't talk or meet other civilizations, but consider this. If they are out there due to the laws of relativity and physics wouldn't we be dead relative to where they are in the our galaxy or elsewhere in the universe? We see their stars in the long distant past so they too would see our corner of the universe as the long distant past.
So the actual barrier for contact is death

That video is hilarious. To think, someone actually takes the film serious enough to test the math after the fact.
It was a fun movie.
