All the galaxies are 99.99% empty! This is a wonderful symmetry, as atoms are also 99.99% empty

For now by the word 'empty', I will just mean absence of normal matter, excluding dark matter, quantum fluctuations etc.

━━━━━━━━━━━━

But the question is why do we see images of galaxies with so densely packed stars, are they wrong?

No, they are not wrong. This illusion is due to the fact that angular distance between two stars in a far off galaxy is too less, enough less to be perceived both stars as one, by our eyes and cameras.

This huge empty space also a major reason why there would be almost no collisions between solar systems and stars when Milkyway and Andromeda, or any other galaxy will collide.

Another milestone. Well done!

Today Is The Day !!

100 years back, on this date, 9th. November '1922, Albert Einstein won the Nobel Prize in Physics

"for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect"
His contribution in the field of Theoretical Physics has blessed entire human society introducing new horizon of practice investigating and unfolding so many secrets of the nature in the universe. A sincere remembrance to the cleverest person of 20th century, Albert Einstein whose contribution are enjoyed by whole human society of earth in various forms!

Step by Step Process to understand QM
You'll need a base in math to start QM
The type of math you would need are
1. Complex Analysis
2. Vector Calculus
3. Linear Algebra
The analytical foundation of Quantum mechanics use all three at the same time simultaneously.

As for the physics part.
You'll need to have atleast a basic foundation in
Hamiltonian mechanics.
For which you need to first understand Lagrangian mechanics.
Hamiltonian Mechanics is just Legendre transforms applied to Lagrangian mechanics.
So you'll need a basic understanding of integral transformations like
1. Fourier series and Fourier Transforms
2. Laplace transforms
3. Legendre Transforms


For integral transforms you can refer to
- Morsche, Berg and Beerends

For Linear Algebra
Elementary Linear Algebra
- by Howard Anton

For intro to Vector calculus.
Try David Griffiths intro to Electrodynamics
The first few chapters have a good explainer on the topic.

For Lagrangian and Hamiltonian mechanics.
- Goldstein is the standard

For intro to Quantum Mechanics.
Honestly you can start with and Intro to Quantum books.
But I personally would recommend a combination of
- R. Shankar for the maths
- David Griffith for the conceptual part.
Infact even David Griffith refers to R. Shankar for the maths

What is theory of every thing?

The theory of everything (TOE) is a hypothetical single, all-encompassing, coherent theoretical framework of physics that fully explains and links together all physical aspects of the universe. It is sometimes referred to as the ultimate theory of the universe. As of yet, there is no accepted TOE, but string theory and the related M-theory have been considered by some to be the closest contenders, as they attempt to unify quantum mechanics and general relativity.

What will happen if we one day formulate it?

If a Theory of Everything is successfully formulated, it would allow scientists to explain and understand the behavior of all types of matter and energy and the interactions between them. It could also provide a unifying description of the universe that encompasses all physical laws, from the laws of motion to the forces of nature. In short, it could revolutionize our understanding of the physical world.

In mathematics there is a statement which says the sum of all natural numbers adds up to -1/12 it is one of the funniest and weirdest statement in mathematics that I have come across so far, how can the sum of all nonfractional positive numbers produce a fractional negative number, is not the summation supposed to be an infinite number?😐
Check out the link below to see how a mathematician proved it.
