Physics - Gravity the most confusing Theory in Physics
HTML-код
- Опубликовано: 6 сен 2024
- Newton describe gravity as a force of attraction between two boides and Einstein described it as curvature of space time. Well both these theories on gravity are very confusing and need much larger explanation.
..............................................
In this video I have brought out the difference between the Newton gravitational theory as well as Einstein theory on gravitation as far as I have understood.

Gravity is not a force. Its a tendency. Matter follows the shortest (Least Resistance) route through Space Time. Im not a Physicist. Im a Dream Analyst, and one of very few real ones on the planet. Its all dependent on how good you are at guessing.
Gravity is not a “force” of nature similar to the Strong, Weak, Electric, or Magnetic Forces, rather gravity is an “effect” which we observe/experience and which emerges out of curved space-time and the “forward-pointing” so-called “arrow of time.”
Wheeler was correct in that “space-time tells matter how to move and matter tells space-time how to bend”.
Suppose that you had a mass (aka: a body) sitting within its own universe of curved space-time. The emergent effect which we refer to as “gravity” would exist within/around that body except at the very center “point” (at the center “point” the surrounding “effect” would cancel out and the center “point” would exist in a “weightless” state. At all other points within the mass and in its very surface, “gravity” as an effect would exist varying as a gradient with its “value” varying between 1 G at the surface to 0 G at the center of mass. At any distance away from the surface is said mass, a “gravitational” gradient as an emergent effect of curved space-time would exist out to the very limit of said universe.
If another body of mass were to be introduced into said universe, said mass would also cause space-time to curve. The two masses would be “attracted” to each other since they would each be moving “along” the space-time geodesic between the two masses owing to the forward-pointing “arrow of time” through curved space-time. Interestingly, if time’s “arrow” could be made to point “backwards”, then the two masses would move away from each other in what would appear to an observer, to be “anti-gravity”.
That's well said, are you a physicist?
@@shamanthgowdajr Unfortunately, no. But GR, cosmology, and QM are some of my strong interests so I read and study whenever I get the chance.
In everyday life, I’m actually a “carpenter” who worked up through the trades to eventually become the president of my own construction company - I specialize in the design and construction of hospitals in California.
@@shamanthgowdajrmy “guess” as to why efforts to date to develop a quantum theory of gravity, have been unsuccessful is that as an emergent “effect” so-called “gravity” in and of itself cannot be quantized.
However, I suppose that space-time and time could each be quantized and then related to QM. (NOTE: This is just a wild supposition in my part and I’m sure that there must be some good physics reason why this has not yet occurred).
Gravity is the physical equivalent or echo of Consciousness in a physical world. Both are all pervading and have centers for evoking activity, not by intent but by their very presence. Both are beyond mind and hence words or definition, they are in the spiritual realms. Their effects can be felt by experience but resist definition, again not by intent but because of their nature. We can keep theorising about it till doomsday and not gain an inch. I would conceive of it as the Consciousness of inert objects.
I may well be wrong.
You are not even wrong. I can see how you could postulate it but you need proof for it, and every claim should be scientifically rigorous. What spiritual is for you could be different for others, but unlike it gravity is the same for everyone even if you do not understand how it works.
I had the same thought.
@@shashankreddy4296 PROOF AND SCIENTIFIC RIGOUR ARE IN THE REALM OF THE MIND. Consciousness is beyond mind and hence cannot be proved. It is upto each and everyone of us whether we can accept it and be happy or run after the treasure at base of rainbow. Each to hos own!
I think you hit the nail square on the head, there. At one time, there was no large mass. So the gravity explanation doesn't really make sense, if it's caused by mass. Cause and effect cannot be the same two things. Gravity is not a force, and I wish they would remove that from the textbooks. Einstein had the right idea, but maybe he got the cause wrong? It seems like he kind of missed on that one. And I've thought about that myself, for a long time. It's pretty much the most ridiculous paradox in physics.
Yes that's absolutely right ✅️

I took physics, back when I got my degree for electronics theory. I had a lot of questions about that. I drove a few professors crazy, but I aced the class. I think space is actually like a huge invisible ocean, with ebbs, flows, and tides. And there are just spherical holes, in space, that matter gets trapped in, when it falls into a spherical well. I think of Earth as a black hole, that doesn't suck quite as much. 😉 I know that sounds funny, but it puts you in the right frame of mind, doesn't it?
@@SloppyGoat yea we can explain things in a lot of ways
@@shamanthgowdajr
It's pretty much impossible to prove it, though. Until we can actually detect and measure space, it can only be envisioned. I can't even imagine a way that could be proven, until then. They have something that kind of works, but it's local. I'm just afraid that, going down the wrong pathway, we'll just delay any progress for thousands of years. We need a new Einstein. 🤔
Hlw. Thank you, and hope you are very well. Your video-making is very good. Your content ideas are very good. If you permit me, I will share some information to increase the channel. You get lots of subscriptions and views. Can I suggest growing your RUclips channel?
Sure❤
