Retrocausality is the idea that the future can influence the past. In certain interpretations of quantum mechanics, events can be affected by future conditions or measurements, challenging the conventional understanding of cause and effect.

Alan Guth on the big bang theory ✍️

Proposed by Sir Roger Penrose, conformal cyclic cosmology suggests that the universe undergoes infinite cycles of Big Bangs and expansions, followed by collapses into a state of low entropy. Each cycle, or 'aeon,' is conformally related to the previous and next ones, suggesting a

This duality can be pursued further and is related to a duality between past and future and the notions of control and knowledge. Thus we may have knowledge of the past but cannot control it; we may control the future but have no knowledge of it.

What is the stupidest argument you’ve heard about the formation of the universe? ✍️

The Mona Lisa is a famous painting by Leonardo da Vinci, a Renaissance artist and scientist. The painting depicts a woman with a mysterious smile and a landscape background. One of the reasons why the Mona Lisa is so admired is because of its use of the golden ratio, a

One word for Maria Skłodowska-Curie? ✍️

The concept of nuclear transmutation (the process of changing one element into another) was first consciously applied to modern physics by Frederick Soddy. In 1901, Soddy and Ernest Rutherford discovered that radioactive thorium was converting into radium. At the moment of

The open society is one in which men have learned to be to some extent critical of taboos, and to base decisions on the authority of their own intelligence.

Ramanujan’s personal handwritten mathematical notes and letters.

Peter Higgs would turn 95 today. He passed away last month this year due to a short illness. In the early 1960s, Higgs and several other physicists independently proposed a mechanism to explain how particles acquire mass. This mechanism, now known as the Higgs mechanism, involves

Radon is a radioactive gas that naturally emanates from the ground, particularly in areas with high concentrations of uranium. It is colorless, odorless, and tasteless, making it hard to detect without specialized equipment.

At its peak, the Manhattan Project employed over 130,000 people and cost nearly $2 billion (equivalent to about $23 billion today). Despite its massive scale, the project remained unknown to the public until the atomic bombings of Hiroshima and Nagasaki in 1945.

The explosion at the Chernobyl nuclear power plant in 1986 caused severe radioactive contamination in the surrounding area. One of the most striking effects was on a forested area near the plant, where pine trees absorbed massive amounts of radiation and turned a vivid red color,
