5 Things You Don't Understand about Gravity

Explore the mysteries of gravity! From Einstein's spacetime curves to time dilation near black holes, discover five fascinating truths about gravity that will change your perspective on the universe.

I have a book on anti gravity, I can’t put it down

That was the funniest "yo mama" joke ever, just cause it came from you of all people. I am still laughing a minute later

Did not have Simon making a your mom joke on my bingo card for this year... That was great. Thanks for the laugh

Fun fact: The ends of the LIGO arms are built up slightly higher than the surrounding landscape, because they had to be so straight, that they had to account for the curvature of the Earth.

I came to get info but ended up getting roasted

Physicist here. Congratulations to the writer Jehron B.! Very well done! Exceeded my expectations by a wide margin.

FUN FACT: Light travels faster than sound. This is why some people appear brighter...until they speak

Fun fact. Gravity loses strength over distance but never reaches 0. So everything in the universe is pulling on you and vice versa.

“Do you hear that Mr. Anderson? That is the sound of inevitability.”

Road runner + anvil + gravity = Flattened coyote.

When I was watching the "Lost In Space" movie with my family, there was a scene in which the planet the ship was orbiting spontaneously (through technological means) collapsed into a black hole. This caused the *Jupiter 2* to begin falling into the newly formed, planet-massed black hole--ostensibly because of the increased gravity, because, well, it's now a black hole--instead of maintaining its original orbit. Out loud, I said, "Oh, COME ON!"

Everyone in the theater looked at me as if I had farted during a ballet.

Sometimes being a physicist makes life difficult...

Another thing with Gravity, GPS has to take account of time dilation for both Special and General Relativity otherwise the accuracy would drift away rather quickly by about 2km per day.

E = mc^2 is not complete BTW. It is actually E^2 = (mc^2)^2 + p^2c^2 to account for massless particles.

In case anyone is curious about the wood engraving at 1:00
It is (old) German and here is the translation (ChatGPT):

Doctor Zirkel (Zirkel is pair of compasses, I believe)

[1st picture:]
From the study's stuffy air,
Dr. Zirkel steps into the morning fair.

[2nd:]
Mr. Zirkel strolls to and fro,
His head heavy with ideas that grow.

[3rd:]
Suddenly he sees with great desire
A ripe apple hanging higher.

[4th:]
Dr. Zirkel thinks: now would be
Quite pleasant the effect of gravity!

[5th:]
And lo, not a minute does flee,
When from the tree he sees the apple free.

[6th:]
How great from the tree the distance is,
The doctor measures with his compass.

[7th:]
Once his thirst for knowledge is satisfied,
He decides not to let the apple be denied.

[8th:]
Though the process isn't fully clear,
Suddenly it becomes perfectly dear.

[9th:]
A new law of nature in space unfurls:
"The apple doesn’t fall far from the tree!!!"

The Zeno Effect. That and Bell's Inequalities. Really are blowing my mind. Then, of course you have Negative Energy, Entanglement, Vacuum Energy, QCD, QED, Field Theory, Tensors, Scalars, Hilbert Spaces, Time Dilation, Antimatter and on and on. You all are cray cray, and I love you.

Correction: The strength of gravity isn't stronger in the center of a planet. It is in fact zero there. Inside a homogeneous sphere, the gravity is linear to the distance from the center.

[FlyWithFitz]

Gravity: Just when I thought I was out, ... pull me back in!

[dellmankawesome]

Thats the thing that genuinely mesmerises me with space is that any question you may possibly answer will only lead to a thousand more questions, something we will never understand or truly comprehend its creepy but amazing at the same time, also the size of it is just ridiculous when you stop to think how truly meaningless and insignificant we are in the grand scheme when not even our solar system would be a grain of sand in the ocean

1:05 is the beginning of the sickest burn ever 😂😂
