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 Einstein’s 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.

We're back

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... https://www.youtube.com/@aryandas5643

The Sun radiates energy continuously into cold space at temperature ∼3K, yet its core remains at roughly 1.5×10^7 K for billions of years. A naive thermodynamic argument says: “Hot objects lose heat, therefore they should cool.” 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... Get skills ppl

NEET exam cancelled?! Tf is up?

#100DaysofBeauty The Preface to the Picture of Dorian Gray

The artist is the creator of beautiful things. To reveal art and conceal the artist is art’s aim. The critic is he who can translate into another manner or a new material his impression of beautiful things. The highest as the lowest form of criticism is a mode of autobiography. Those who find ugly meanings in beautiful things are corrupt without being charming. This is a fault. Those who find beautiful meanings in beautiful things are the cultivated. For these there is hope. They are the elect to whom beautiful things mean only Beauty. There is no such thing as a moral or an immoral book. Books are well written, or badly written. That is all. The nineteenth century dislike of Realism is the rage of Caliban seeing his own face in a glass. The nineteenth century dislike of Romanticism is the rage of Caliban not seeing his own face in a glass. The moral life of man forms part of the subject-matter of the artist, but the morality of art consists in the perfect use of an imperfect medium. No artist desires to prove anything. Even things that are true can be proved. No artist has ethical sympathies. An ethical sympathy in an artist is an unpardonable mannerism of style. No artist is ever morbid. The artist can express everything. Thought and language are to the artist instruments of an art. Vice and virtue are to the artist materials for an art. From the point of view of form, the type of all the arts is the art of the musician. From the point of view of feeling, the actor’s craft is the type. All art is at once surface and symbol. Those who go beneath the surface do so at their peril. Those who read the symbol do so at their peril. It is the spectator, and not life, that art really mirrors. Diversity of opinion about a work of art shows that the work is new, complex, and vital. When critics disagree, the artist is in accord with himself. We can forgive a man for making a useful thing as long as he does not admire it. The only excuse for making a useless thing is that one admires it intensely. All art is quite useless.

So guys, I'll be back for my final run to 3k subs. The math-heavy posts will decrease from now that some of the heavy mathematics are done! From now on, I will be posting twice a month (on the 15th and on the 30th, hopefully... please, oh god!!!), and let's hope we reach that milestone of 3k subs soon enough. My next post will be on shifts, how they work in space, how distances are calculated based on them, and a lot more stuff. Hopefully, you will enjoy this final run. Stay tuned ;) Join @spacemathsphysicslearners till then!!

Guys sth came up at 5:30 pm tomorrow so I'll postpone to next Sunday, I hope it is fine for you!

So guys I'll be coming live on March 22nd to listen to your ideas on what the next topic of my post can be, if you have any physics ideas to discuss and a lot of other stuff... Please do try to join!
