Act 513. Gravity and space-time distortions

Reiner's words seemed to throw a pebble into the otherwise calm lake, and since then, the surface of the lake has rippled and is no longer smooth.

"Time and space are distorted?"

Lord Braggs was enlightened and repeated Reiner's words.

"Under the original theory of relativity, space-time should be flat, which would explain the problem of the speed of light, but the consequent observation of light bending in a gravitational field makes the theory of relativity incomplete."

Reiner said, waving his hand, and the light formed a simple galaxy shape, a pattern of a planet orbiting a star.

"In the past, we thought of gravity as the mutual attraction between objects, like a rope connecting two objects."

With Reiner's words, a thin line stretched out from the star, connecting with the planet, as if the planet was being pulled by the star in motion.

"This is the mode of gravitational action in a flat space-time, and it can be seen that if this is followed, then for objects in distant places, gravity will take a certain amount of time to act, and the movement of the stars in the whole universe will show an extremely chaotic pattern."

After a period of calculations, Reiner calculated a celestial system of stars and three planets, substituting the concept of gravitational velocity, and it can be seen that its movement is extremely irregular, which is completely different from the observation.

"Then we can either assume that gravity does not require time and exceeds the speed of light, which is contrary to the theory of relativity, or we can assume that gravity is not an interacting force in the usual sense."

Reiner snapped his fingers, and the chaotic and irregular movement of the stars immediately stopped.

On this plane, Reiner reached out and gently pulled down.

He created a depression in the plane where the star was located, like a heavy iron ball falling on a flat cloth, distorting the entire plane due to the mass of the star.

Reiner then severed the line between the star and the planet.

With a snap of the fingers, the entire celestial system was in motion again.

At this time, the mages were amazed to see that the movement of the planets towards the star due to the depression of the plane, combined with the forward speed of the planet, formed a perfect balance, so that the movement of the planets around the star formed a perfect and regular pattern of motion.

"This is just a demonstration image, and the distortion of real four-dimensional space-time is not so simple, but it can also reflect my conjecture."

Looking at the star map that was constantly rotating on the sunken plane, all the mages were silent.

"Space-time is not flat, everything with mass causes space distortion, and the greater the mass, the greater the distortion, and I make the degree of space distortion curvature, so that we can explain why light deflects around massive objects."

Reiner explained.

"In the original theory of relativity, light always moves along the shortest path between two points, which seems to be incorrect in the case of gravitational deflection, but if it is said that a massive object causes the bending of space-time can solve this problem, that is, light always moves along the shortest path, but light cannot penetrate space-time, but can only move in distorted space-time, so in our opinion, this produces the phenomenon of light deflection!"

"At the same time, the distortion of space-time also explains the transmission of gravity, the reason why gravity can be transmitted beyond the speed of light, not because it travels extremely fast, but because gravity does not need to propagate at all, and the essence of gravity is the interaction caused by the curvature of space-time caused by massive objects!"

Reiner said that the circle of calculations around him was in full swing, calculating the angle of deflection of light after adding space-time warps.

Soon, Reiner got his answer and showed it to everyone.

The value is almost identical to the observation, which is exactly double the value calculated according to the original law of gravitation!

“...... Space-time warp ......"

If Lord Alberton had realized, he was also calculating in his head.

If space is not flat, if the presence of objects affects space, if gravity is really caused by the distortion of space-time......

"This would explain why time becomes slower around massive objects, because light travels around these objects at the same speed, it needs to travel more time in distorted space-time, and as a result, the passage of time becomes slower......"

Lord Alberton has solved a question that has puzzled mages since the theory of relativity was proposed, and that is why time flows slower in a strong gravitational field.

"Wait, based on this inference, can we assume an extreme case where the speed of light travels in a certain value when the gravitational field is so large that it becomes so long that it is impossible to escape?"

His Excellency Pragues's words were like a thunderbolt, causing Lord Alberton and Field to encounter a bolt from the blue.

"We can do the math."

Reiner immediately began to calculate, and immediately after, the other mages also substituted the values and performed the calculations.

This process lasted for half an hour, and the entire control room was silent.

Phyllis looked at them, and although he couldn't really understand it with his level of magic theory, Phyllis could feel that these mages seemed to have discovered some incredible secrets of the world, and she looked at Reiner, feeling that Reiner, who was seriously calculating and deducing at the moment, had a completely different charm from usual.

Finally, Reiner was the first to get the result.

The results show that when the extremely large mass is concentrated on a small point, it will produce an extremely powerful space-time distortion, so that a region around the point will be generated, and in this area, light will not be able to escape, which means that the horizon around the singularity will be completely dark.

At the same time, this singularity will trigger a series of relativistic effects, including the fact that time near the singularity will be greatly delayed, and on the surface of the event horizon, outside observers will even observe that time stands still, and at the same time, the strong gravitational pull of the singularity will cause the light of nearby galaxies to be distorted, and in short, the values of some mathematical constants on these galaxies may change.

This singularity is like an abyss that devours everything, and even the fastest light in the universe cannot escape from its grasp.

"Such a singularity, I think it can be called a black hole."

Reiner said, looking outside, the spatial distortion that shone in the glow of the searchlight.

"And the past theory of relativity should also be revised, from the original special theory of relativity to the current general theory of relativity."
