Is gravity broken? #science #breakthrough #gravity #space

Gravity is odd in that its strength attenuates as you get further away, it never goes down to zero. So, its the force that binds the universe together. Obiwan was right.

This pop science way of talking always bother me. Newton wasn’t wrong because of Einstein. While Einstein allowed for more science to be written, Newton’s work wasn’t thrown out. At best you talking about modifying 1% of existing understanding under specific unusual circumstances. The way you talk is how flat earthers are born. “We learned something new, all of science is wrong”… that’s not how science works.

Does it really “rewrite” or does it continue increasing our existing understanding by adding additional nuance?

If this is the same paper based on observations of long-distance binary star pairs, then there's another paper that supposedly uses the exact same data but comes to the exact OPPOSITE conclusion that this paper does. Dr. Becky on her astronomy YT channel does a great breakdown about it.

We got the new gravity theory before gta6

It explains the discrepancy on why the Voyager spacecrafts are not where we thought they should be like Neil Degrass Tyson talks about. Time slows as you get away from the gravity of masses. Makes sense to me

There is a lot of bad science, but much, much more bad science journalism.

A hope our understanding of gravity changes, now, it's so different, can't be quantized.

[matthewcarter]

This has been in circles for decades. We have long known there are inconsistencies in how gravity works at extreme distances. Mond was partially created to solve these issues. This is why serious studies have been put into dipole dipole forces and their contribution to gravity. (I know a japanese team stated that london forces alone could not replace gravity, however I have yet to see any studies investigating it has a summary component of gravity. Especially due to the many similarities between gravitational and magnetic equations.)

If the inverse square law could be measured with a precision much higher than we can measure could at some point show us the way

[patrickm]

Newton figured out gravity for classical objects, Einstein refined our understanding to work in situations of extremely high gravity. It stands to reason we need to refine our understanding to also include extremely low gravity.

I think this would be a well needed change in physics. It could prompt the invention of a new theory, one which may relate better to our quantum model as well and therefore birth a theory of everything.

For people saying this isn't a big deal, it isn't in most cases, but when looked at from the grandest of scales, it's s big deal. When Einstein proposed his theory, Newtonian gravity wasn't thrown out the window, but we still know it's not the best model for our universe. The same can happen here, relativity isn't going to be thrown out, but we would know it to be incorrect.

I only saw the thumbnail so i thought this was going to be about pills

My study of gravity over the last 30 years is how the force of gravity has increased over the millions of years that life has evolved. It explains how dinosaurs were able to exist and how continents separated. A possible explanation is whether neutrinos have mass. Many on going experiments are trying to determine this. Think of neutrinos as the sweat of our sun and other stars in our galaxy fuming off and passing through us and earth imbuing mass to the dense center of earth causing the earth to expand.

[SirPhysics]

An important thing to note which often gets left out by science journalists chasing sensational headlines is that even if there were true it would not negate general relativity in all of the realm where it works exceedingly well for the exact same reason that general relativity did not completely replace Newtonian gravity (which NASA still primarily uses when landing their rockets on asteroids and other bodies). Any new theory of gravity would need to reduce down to the current theory in the relativistic limit, whatever that turns out to be.

A three d object sitting on or distorting a blanket should attract only one side. The curvature by appearance is a omni directional.

[Lilcezar]

I have to look it up again but I remember there was a channel I was watching and it was talking about some old person in history saying that gravity isn't the fundamental of our Earth and rather that time is which makes no sense when you just say it like that but when you get into his theory it kind of does

[Nawaf-]

Einstein’s idea is not similar to Newton’s… Einstein said that space pushes the objects instead of objects attract each others. It is a hallucination at best.

[akaraven]

This just shows that we know almost nothing, just theories on what we think we know, and what we think we know is proven wrong time and again.

Some new discoveries add to our current understanding to show we were on the correct path, but alas not correct, some new discoveries show we were entirely wrong.

At the end of the day gravity is just a theory based on what we know and what we can study, and when Newton theorised it he only had Earth to really give a theory about, Einstein did not have much more to work with.

But the deeper our understanding the more we can uncover, and with new technologies we can go deeper again to realise we just don't know.

[advaitrahasya]

It seens physicists still think a mathematical model is an understanding of mechanism.

Like geocentrists trying to explain planets going retrograde 😂
