If light has no mass, how is it affected by black holes? The answer is: massive objects bend the "fabric" of space-time, so light travels along a different path than it would have if the massive object were not there. [🎞️physicsgene]

All this is presumption.

“Science doesn’t tell us why the Big Bang happened, how the singularity occurred in the first place, or why it exploded when it did. It tells us there is objective scientific evidence that it occurred. So, what exactly was the Big Bang?” – Book III The Enigmatic Mystery

or it's not possible to bend space or time and we are missing what really causes Gravity.

That’s not an answer, it’s a hypothesis.

Nonsense. Only if you define that the speed of light is a constant, then the only way to explain the longer travel time if light near a mass, as observed with the Shapiro delay, is by assuming that spacetime is curved. But when you define that spacetime is flat, then you explain the same observation with a change of the refractive index of space as a function of the mass distribution. The higher this refractive index goes above 1, the slower light propagates. Stop thinking that space changes its geometry. The content of space changes always. We, our particle function, slow down near gravitating masses. Light propagation slows down. At the EH of the BH, all light comes to a halt, and all particles condense to a particle condensate that covers what condensed there before.

Yes, that is the the effect. However, what exactly is the "fabric" of space and time that is being bent?

So wait, then light isn't sucked in? It just travels around b/c of the space-time bending?

Fun fact: Black holes have such strong gravity that not even light can escape them! 🌑💡 This is why they appear "black"—no light can be emitted or reflected from inside the event horizon, the point of no return. It’s one of the most fascinating mysteries of the universe!

@lavanaz That would be a good explanation for the halos we see. It's not what is inside refelcring off the dome- it's light from outside hitting the surface and projecting a ring....interesting...

How it is possible to something is moving faster than the speed of light if the speed of light in the fastest thing in the universe?

Ever hear Albert Einstein’s voice? He’s him explaining his formula, E=mc² It is probably the most famous formula in the world, but what exactly does it mean? Let's start by defining each letter in the formula: E = Energy M = Mass C = Speed of light (a very large number) If we were to read the formula, we would say, "Energy equals mass times the speed of light squared." The formula itself is rather simple in that it essentially says that energy and mass are different forms of the same thing; they are interchangeable. So are you saying a beam of light and a banana are different forms of the same thing? Yes, in our head, this may not make sense, but it does in nature. This discovery was groundbreaking at the time because people had previously believed that energy could only be created by kinetic or potential energy. You can increase kinetic energy by accelerating your car. You can increase potential energy by stretching a rubber band. Einstein demonstrated that there was a third form, which is that things have energy because they simply exist. Ok, so why is mass multiplied by the speed of light? Whenever you are converting mass to pure energy, it is by nature moving at the speed of light. Pure energy is an electromagnetic radiation, which travels at 186,000 miles/sec (300,000 km/sec). Ok, cool, but why is the speed of light squared? This again has to do with the nature of energy. If an object is moving twice as fast as another object, it does not have twice as much energy. Rather, it has four times as much energy. Hence, the speed of light is squared, which comes out to a very big number. C^2 is the conversion factor from mass to energy. The bottom line is that even small objects have an immense amount of energy. Through the process of nuclear fusion/fission via nuclear power plants, we can harness some of this energy. In the atomic bomb that destroyed the city of Hiroshima, there was about 700 milligrams (equivalent to the weight of 1/3 of a dime) of uranium which was converted to energy that destroyed everything within a 1-mile (1.6 km) blast radius.

Stop whining about how everything feels so dark around you, step up and be the light. Because every action has an eagle on opposite reaction, so the darkness proves that light is there. And if you can see it, it gotta be in you. LIGHT IS IMMINENT! #crying #light

When Light Becomes Heavy Enough to Trap Itself Can light collapse into a black hole? In General Relativity, light is not weightless in the geometric sense. It has energy, it carries momentum, and energy curves Spacetime. A Vaidya-type collapse describes a mass that grows because radiation is falling inward. The mathematics is the same brutal idea behind Einstein’s equation Gᵤᵥ = 8πTᵤᵥ If the stress-energy Tᵤᵥ is made from radiation, then light itself becomes a source of curvature. As more radiation falls inward, the mass aspect grows, the Spacetime fabric tightens, and a clean black horizon appears where escaping paths begin to fail. #GeneralRelativity #EinsteinEquations #BlackHole #Spacetime #Astrophysics #TheoreticalPhysics #Light #Mathematics #Science

Ever look up at the sun and think it’s yellow? Neil deGrasse Tyson explains that it is actually white. The only reason we see it as yellow or orange is because our atmosphere filters the light. It scatters away the blue wavelengths more strongly, leaving the warmer tones, especially when the Sun is low on the horizon. If the Sun were truly yellow, snow on Earth during the middle of the day would also look yellow instead of white. That is because sunlight defines how we see color in everything around us. It shows how what we perceive as reality is shaped by the interaction between light and the medium it travels through, rather than being a fixed property of the objects themselves.

Some people have DMed me saying that it is impossible for things to move faster than the speed of light as described by Einstein’s theory of general relativity. Therefore a higher intelligence from another star system would be too far away to visit earth. Here Bob Lazar explains how a gravitational drive (warp drive) operates by distorting or warping space-time. The spacecraft itself is not actually moving/traveling in linear space therefore it has a linear velocity of Zero. It is not actually moving in Newtonian physics terms. Thus it is not traveling faster than the speed of light and Einstein’s theory of general relativity stands. Watch this short 3 minute clip: 👇 UAP James

‘Allah is the Light of the heavens and the earth. The example of His light is like a niche within which is a lamp, the lamp is within glass, the glass as if it were a brilliant star, lit from a blessed olive tree, neither of the east nor of the west, whose oil would almost glow even if untouched by fire. Light upon light. Allah guides to His light whom He wills. And Allah presents examples for the people, and Allah is Knowing of all things.’ 📖 Surah An-Nur — Ayah 24:35

💬 President #Putin: If common sense in the West prevails, it is possible to reach an acceptable solution to the Ukrainian conflict. It seems to me there is “light at the end of the tunnel”, so to speak. ❗️ If not, we will have to achieve all the goals by military means.

Few realize how close we are to a complete Physics revolution. Particle physics is about to be replaced by quantum-wave theory. There is no inconsistency between quantum and macro. Mass is energy. Standing waves produce coherence. The double slit experiment is the gateway to our new understanding. Think about what the answer must be. The electron is traversing all possible paths. How? Space is not empty. All points in space and time are connected. We can travel faster than the speed of light.

You can model a lightning strike by letting it solve a maze. If there is no connection, nothing happens. The air simply resists. If there is a connection, that path becomes the easiest route, so the discharge snaps through it.

What if drop shadows actually look like real shadows? We are using Omma to explore a new kind of canvas that employs real-light approximations rather than simple 2D drop shadows. It runs on WebGPU and uses real-time path tracing to simulate more realistic shading. It also supports SVG shapes. The Z-index defines actual depth, too (objects with a lower z-index would be affected by shadows of other objects).

This well known Pakistani influencer says speed of sound is faster than speed of light because when Muslims do dua (prayer) it travels faster to Allah than light traveling in space. And the crowd applauds to such nonsense. No wonder Pakistan is doomed to fail.
