Is Gravity Broken? The Shocking Discovery That Could Change Everything

Gravity is one of the most fundamental forces of nature, but it might not work the way we think it does. A new study claims to have found evidence for modified gravity at very low accelerations from the observations of wide binary stars by the Gaia space telescope. This discovery could challenge the standard theories of gravity and open up new possibilities for understanding the universe. In this video, we will explain what modified gravity is, how it was detected, and what it means for our view of reality.

i wanted to be an astronaut in elementary school and didn't make the grade. I'm so glad to see where we are at, in our surroundings. Great presentation. Glad I subbed.

Every day new telescopes and new discoveries blow away existing theories. We don't even really understand light, much less gravity, so I have full confidence that people will discover the physics that provides limitless energy and allows warp speed travel around the galaxy.

This video tells me that there are many scientific models that we think are on super solid grounds. Red shift, dark matter, dark energy, the solar model, standard model, BIg bang theory…
And as we gather more data abd we stop ignoring data that does not fit the current models, we will doscover new things

It's not a weak gravitational acceleration. It's a slow but constant acceleration over time, in/s² (0.0000122 cm/s²). I discovered it many years ago while measuring the motion of our solar system, Milky Way galaxy and 5 other satellite galaxies. It explains them all. I called it the AP theory for accelerated propulsion theory. Same finding, different name. I published a book a few years ago explaining it called DARK MATTER: WHAT'S WRONG WITH GENERAL RELATIVITY? This theory was recently published. I beat them by 2 years.

The motion of stars deviate from the laws of motion when stars reach a million years old. Anything older than a million years shows up as an anomaly, no longer fits Newtonian physics. This is why young stars like S02 and other S-type stars in the galactic core don't seem to be affected by dark matter. It's why planets, moons, and other bodies in our solar system don't seem to be affected. It's the reason why stars and satellite galaxies traveling more than 1 million mi/h orbiting some 200, 000 light years away from the core are unable to reach an escape velocity. If the galaxy was surrounded by a dark matter halo the stars and satellite galaxies would have lost gravity cohesion, yanked out of the galaxy. I even explained why the lensing of light is not caused by missing mass. I came up with the solution several years ago.

This does open up some interesting questions.

Fascinating video! Thank you, we have so much more to explore and explain-

[darthjarwood]

hopefully this will at least open some doors and possibly inspire the discovery of the universal equation

[Markoul]

For accelerations below 0.6 nm/s^2 !! Is this not a bit far stretched? To claim that MOND is the reason of the unexplained rotation speed of galaxies that I am sure they have much more gravitational acceleration than this threshold? Do you mean other far away gravitational influence form other galaxies are responsible for the higher spin rotation of a particular galaxy. This reminds me more like to the Mach's principle.

If you ask me the increased rotation of speed of galaxies is due to the vacuum polarization in near-by space around the galaxy that acts effectively as having more mass in the system approaching the outskirt of the galaxy.

At last! Instead of clinging to Newton's equation of gravity as being exact, rather than a first-term approximation, scientists might seriously consider that the dark matter that they have failed to find after 40+ years of fruitless searching is a myth. As a scientist myself, I have never understood why some physicists have had such faith in Newton's Law being exact.

[peterbroderson]

The moment a particle is a wave; it has to be a conscious wave!
Gravity is the conscious attraction among waves to create the illusion of particles,
and our experience-able Universe.
Max Planck states: "Consciousness is fundamental and matter is derived from Consciousness".

Life is the Infinite Consciousness, experiencing the Infinite Possibilities, Infinitely.
We are "It", experiencing our infinite possibilities in our finite moment.
Our job is to make it interesting!

This is not exactly an easy area for research... thanks for the interesting video, "NSN" (and comments of other interested and well informed users here)!
Also in many other cosmic events such as e.g. during the explosion/implosion of a supernovae, the normal gravity force gets distored and requires a "recovery time" to find order (within the gravitational fields) again. So gravitation is highly dependent on the dynamics of the circumstances in which we can find all sorts of events...
To put it simply, gravity brings order to chaos and puts matter in an orderly orbit, on which some changes can also be observed depending on the circumstances...
Initially, as correctly mentioned here in the lecture with binar star systems, with slow (but constant) acceleration speeds of gravity. But it is maybe a bit difficult here to bring this fluctuations or changes into a cosmic standard model or even in a formula...

Focus of the same frequency can breakdown gravity?

[Hydroverse]

I personally see gravity as an energy source. My thought process is that the heat from friction during precipitation isn't stored evaporation heat energy that comes from converting mass into energy like fusion in the sun or oxidation in a campfire. That heat is lost to space during the condensation phase, so if gravitational acceleration is being dissipated as heat, then it would seem that gravity is energy.

[graemesandstrom]

Thank you for that clear description of the MONDs theory. I almost understood. (Just joking). What a cleaver way to try to pinpoint the point at which the deviations begin to occur! This approach makes a lot more sense than banging your head against a brick wall with Dark Matter!

[richardmercer]

Discoveries don't change anything, except (hopefully) our understanding... and gravity can't be broken, unless someone dropped it. I suppose I'll watch anyway as the video is likely pretty good in spite of the title.

[r.i.p.volodya]

This is fantastic! I was never convinced by the dark-matter hypothesis and always felt that our limited knowledge of gravity was behind the rotation curves.

[boostny]

This makes sense then. It's now as easy as stretching of a thick rubber band. As it gets stretch farther out it requires extra force and thus slower to stretch at the maximum point and until it breaks. There may be an invisible rubber band surrounding the outer boundary in all star systems. In other words it's planets and galaxies doing all the work not external stuff. 😊

So perhaps angular momentum may play a part, when it comes to gravity? Can we measure, or have a scale, when it comes to angular momentum? Is there a "phase change" between smaller and larger gravity wells? Doses space-time curvature change on smaller or larger scales. I have often wondered about using the "voids" that are scattered around the Universe as a experimental laboratory. They are low gravity areas, and may play a role in studies of Gravity, MOND, Black Holes and other phenomena. Could you or I write about these things without using the word, gravity?

[Insomn]

Dark matter has always been a placeholder bandaid over gravity. Even if it looks like the universe HAS dark matter, we'd have no idea why it NEEDs dark matter. What, to keep galaxies together? Why would the universe care about that? Introducing dark matter into our model is basically saying that the universe decided to look a certain way, which is stupid. We will eventually figure out the exact mechanism of gravitational pull, and we'll see that it behaves differently at larger scales. We need to think about it 5 dimensionally or something.

[mykofreder]

Here is my take on different gravities within our galaxy, the MOND separation as the factor does not make a lot of sense to me. The location within the galaxy causing different gravity and spin rates does though. Mass or atom use gravity for some purpose and depletes it support, it exits at the speed of light local and produces the gravitational effect as inverse square mixing with background as it exits creates inverse square supports, and inverse square gravity. Light years away I think it approaches background levels, maybe adds some directional momentum to the background and joins the background, and it slowly exits the galaxy that is quite large and the depleted fluid may take millions of years to reach the intergalactic background. It also may be reused and further depleted by some other matter. Matter in the core of the universe is using much more already depleted gravitational fluid than the arms, which is more depleted than between the arms. If the fluid used for gravity is more depleted maybe the gravity is weaker, they should correlate the spinning with approximate densities the spinning objects reside in.
