How Mass distorts Space-Time

It’s not gravity which distorts Space-Time. The bending or distortion of space-time is due to the mass. If there is more mass, more will be the distortion.
Einstein’s Theory says Gravity is not a force. But a manifestation of Spacetime curve.
If Space-time is flat, means so-called Euclidean and that geometry is called Minkowski. There is no Gravity, no mass at all. or if there is a mass the mass is so small, like an atomic scale. In atomic scale the Space-Time is flat. There is no effect of gravity on that scale. What we best do is neglect the potential due to gravity, because it’s magnitude is so small than any other interactive force like Electromagnetic, Nuclear interaction.
By using the Space-time idea, people have construed Relativistic QM. But due to so much mathematical inconsistency, this theory is no longer valid. People have evaluated more advance theory like QFT (Quantum field theory), Which is consistent with Einstein’s special theory of relativity.
Scientist used to explain the Space-time structure some sort of Rubber Sheet, in which u put some mass and there is a bending due to that mass, which u experience as a gravity. These Space-time concepts are totally mathematical. U can’t see such kind of thing if u see out there using telescopes. But u can always experimentally verify it, This idea works. So, space_time geometry is valid. But still, its a big question that What is Space-Time.
Under certain limit, General Relativity becomes Newtonian gravity. U see Newtonian gravity is also valid for low speed than light and mass not equal to zero.
U can’t predict what kind of shape space-time will take, But when U you make your own guess and that guess explain the experiment you can say that this kind of geometry is there due to any heavy object, like stars, Black holes. Like Schwarzschild Metric, To explain the Blackhole Space-Time.
So if You want to know there are tons of book out there.
Gravitation by Kip Throne
Spacetime and Geometry: An Introduction to General Relativity
by Sean Carroll (Author)
You can follow the Lectures of Prof. Leonard Susskind. It’s one of the best lectures for Beginners.
I hope U got the answer. Give me comment if u have any problem related this explanation

IST CHAPTER UNITS & DIMENSION ANALYSICS

UNITS- Q uestion you need ton first understand the meaning of science. Science means MEASUREMENTS. In every field of science we do measurements, science only cares about measuring things. That means the things have to be observable. That’s why in science we don’t take care about FEELINGS. Because we can’t measure feelings. Now as we measure something, we need to represent it in some notation to identify or distinguish between quantities. Because whatever we measure it’s just number, if I say you the speed is 5. What info can you tell about 5, it’s just a number, it nothing tells you about anything related to speed. So you need to specify specific quantities to extract info. Actually speed refers to unit distance travel in unit seconds. So the unit distance can be shown in centimeters, meters, and kilometers. Generally we show distances in meters because it acceptable internationally and it is general notation we use in physics. So the (SI) unit of speed is meters per second. So, yo...

Scattering In Quantum Mechanics

Scattering Amplitude  Spinless Particle  we are dealing with quantum description of scattering.  Elastic Scattering $ \rightarrow $ between two spinless, non-relativistic particles of masses m1 and m2. During the scattering process, the particles interact with one another. If the interaction is time independent, we can describe the two-particle system with stationary states.  \begin{equation}\Psi\left(\vec{r}_{1}, \vec{r}_{2}, t\right)=\psi\left(\vec{r}_{1}, \vec{r}_{2}\right) e^{-i E_{T} t / n}\end{equation}  $ E_T $ is total energy.  \begin{equation}\left[-\frac{\hbar^{2}}{2 m_{1}} \vec{\nabla}_{1}^{2}-\frac{\hbar^{2}}{2 m_{2}} \vec{\nabla}_{2}^{2}+\hat{V}\left(\vec{r}_{1}, \vec{r}_{2}\right)\right] \psi\left(\vec{r}_{1}, \vec{r}_{2}\right)=E_{T} \psi\left(\vec{r}_{1}, \vec{r}_{2}\right) \end{equation}     defining $ ...
