I started this channel because I thought that one day I will be successful in creating a network where people discuss stuff which they love in astrophysics. So let's shake hands and create an environment everyone wants to have- Let's enjoy this journey.

In structural chemistry, many molecules or ions (such as benzene, or the carbonate ion, cannot be accurately represented by a single Lewis formula. Instead, we draw multiple valid Lewis formulas called resonance structures (or canonical forms) and describe the real molecule as a resonance hybrid with intermediate bond lengths and properties.
Can chemical resonance be accurately thought of as an example of quantum superposition?

It is said that the curl of a gradient is 0 or specifically:
ā x (āT) = 0
This also shows that energy is conserved mathematically... Then why is the Noether's theorems required?

A historic sweep for the Indian IPhO 2026 team, with all 5 members getting a gold. Congratulations team India and join me in congratulating one of the gold medalists, @RiddheshAB7...
Moving on to the International Mathematical olympiad 2026, which is being held in China! All the best to team India and the world. Lets hope for one of the best problems to come on the 15th and the 16th July 2026...

The cosmological principal states that on a large scale, the universe is homogeneous (uniform in density) and isotropic (looks the same in all directions).
This is a crucial fundamental assumption by astronomers and cosmologists, which provide many shortcuts in studying the universe. For example, physical laws which apply locally, apply universaly as well... We do not need to derive new laws of physics for every distant galaxy.
This principle was also key in foundation for the standard model. By applying the principle to Einsteinās General Theory of Relativity, scientists formulated the Lambda-CDM Model, which accurately describes a universe that expanded from the Big Bang and contains both dark matter and dark energy.
However a recent journal in Nature, challenges this core principal. Here is the research paper, do read it-

Telegram is banned in India until June 22, 2026. Looking at the harsh conditions of Telegram in India and obviously the incapability of the government in conducting national exams, telegram may face permanent ban at any moment.
This audience is very dear to me and I wouldn't like to lose you all. So I would request you to subscribe to my YT channel, so that we can shift there, if TG is ever banned...

The Sun radiates energy continuously into cold space at temperature ā¼3K, yet its core remains at roughly 1.5Ć10^7 K for billions of years.
A naive thermodynamic argument says:
āHot objects lose heat, therefore they should cool.ā
However, stars do not behave like ordinary systems.
Explain why a star can radiate enormous amounts of energy for billions of years without catastrophic cooling, and why, during some phases of evolution, losing energy actually increases the core temperature.

I was ofc checking you guys!
The real answer is 0.1 Mpc. Hubble's law won't work here because the universe isn't isoprotic and homogenous throughout... Considering the galaxy is a milky Way satellite, the only possible distance is 0.1 Mpc...

In stellar cores, nuclear fusion occurs at temperatures that are far lower than what would be required for nuclei to classically overcome the Coulomb barrier.
Which of the following best explains how fusion is still able to proceed under these conditions?
