The Tarantula Nebula (NGC 2070) is located in the eastern portion of the Large Magellanic Cloud. It is the only extra-galactic nebula that is visible to the naked-eye. If NGC 2070 were as close as the Orion Nebula (M42), it would take up the entire constellation of Orion and be bright enough to cast a shadow.

Volcanic lightning is an electrical discharge caused by a volcanic eruption rather than from an ordinary thunderstorm. Volcanic lightning arises from colliding, fragmenting particles of volcanic ash (and sometimes ice),which generate static electricity within the volcanic plume,leading to the name dirty thunderstorm.Moist convection and ice formation also drive the eruption plume dynamics and can trigger volcanic lightning.Unlike ordinary thunderstorms, volcanic lightning can also occur before any ice crystals have formed in the ash cloud.

Volcanic lightning is a visually incredible.

Physics is to be regarded not so much as the study of something a priori given, but rather as the development of methods of ordering and surveying human experience. In this respect, our task must be to account for such experience in a manner independent of individual subjective judgement and therefore objective in the sense that it can be unambiguously communicated in ordinary human language.

~Neils Bohr, Danish Physicist one of the founders and pioneers of Atomic Structure And Quantum Theory, for which he received his Nobel Prize in physics in 1922.

I imagine that whenever the mind perceives a mathematical idea, it makes contact with Plato's world of mathematical concepts... When mathematicians communicate, this is made possible by each one having a direct route to truth, the consciousness of each being in a position to perceive mathematical truths directly, through the process of 'seeing'.

~Roger Penrose

Roger Penrose is a British Mathematician and mathematical physicist who won the 2020 Nobel Prize for his work on Black holes--- the black hole formation is robust prediction of the general theory of relativity.

I think it's much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers and possible beliefs and different degrees of uncertainty about different things, but I am not absolutely sure of anything and there are many things I don't know anything about, such as whether it means anything to ask why we're here. I don't have to know an answer. I don't feel frightened not knowing things, by being lost in a mysterious universe without any purpose, which is the way it really is as far as I can tell.

The problem with today's world is that everyone believes they have the right to express their opinion AND have others listen to it.

The correct statement of individual rights is that everyone has the right to an opinion, but crucially, that opinion can be roundly ignored and even made fun of, particularly if it is demonstrably nonsense!

"I am enough of an artist to draw freely upon my imagination. Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world."

-- A. Einstein (1879-1955)

WHAT DO YOU THINK, ARE WE ALONE?

Sir Raman experimented with Change in the wavelength of light that occurs when a light beam is deflected by molecules. When a beam of light traverses a dust-free, transparent sample of a chemical compound, a small fraction of the light emerges in directions other than that of the incident (incoming) beam.
During his lifetime, he published about 21 studies in domestic journals and 146 publications in foreign journals. For his remarkable work in Physics which is known as the “Raman Effect,” CV Raman was awarded many prizes which include the prestigious Nobel Prize. His work on the phenomenon of the scattering of light was instrumental in modern Raman Spectroscopy. In the year 1924, he was elected to the fellowship of the Royal Society of London and in 1929, he was conferred with the knighthood title of ‘Sir’. Besides being honoured with Lenin Peace Prize in 1958, CV Raman was awarded the highest civilian honour ‘Bharat Ratna’ in 1954 by the Government of India.

I am interested in the evolution of intelligence for another reason as well. We now have at our command, for the first time in human history, a powerful tool- the large radio telescope-which is capable of communication over immense interstellar distances. We are just beginning to employ it in a halting and tentative manner, but with a perceptibly increasing pace, to determine whether other civilizations on unimaginably distant and exotic worlds may be sending radio messages to us. Both the existence of those other civilizations and the nature of the messages they may be sending depend on the universality of the process of evolution of intelligence that has occurred on Earth. Conceivably, some hints or insights helpful in the quest for extraterrestrial intelligence might be derived from an investigation of the evolution of terrestrial intelligence.
