Neil Turok: Physics is in Crisis

Renowned physicist Neil Turok, Holder of the Higgs Chair of Theoretical Physics at the University of Edinburgh, joins me to discuss the state of science and the universe. is Physics in trouble? What hope is there to return to more productive and Simple theories? What is Peter Higgs up to?

Neil Turok has been director emeritus of the Perimeter Institute for Theoretical Physics since 2019. He specializes in mathematical physics and early-universe physics, including the cosmological constant and a cyclic model for the universe.

He has written several books including Endless Universe: Beyond the Big Bang and The Universe Within: From Quantum to Cosmos.

00:00:00 Intro.
00:03:28 What is the meaning of Neil’s book cover?
00:06:46 The Nature of the Endless Universe.
00:14:31 What would happen to James Clerk Maxwell and Michael Faraday on Twitter?
00:16:10 What’s wrong with physics today?
00:20:06 How did Neil’s life change after his theory was proven wrong?
00:23:28 Neil shows us fundamental laws of the Universe in equations.
00:33:59 How well do our modern equations satisfy the conditions of the observable Universe?
00:56:29 How is the Universe simple?
01:20:01 Can Neil’s model explain flatness without inflation?
01:54:54 Existential Questions on the meaning of life, advice to his former self, and things he’s changed his mind on.

AI algorithm pinpoints 8 radio signals that may have come from aliens

Is this the breakthrough the world has been waiting for from the Search for Extraterrestrial Intelligence Institute?

A scientist, Peter Ma, has applied machine learning and artificial intelligence to data collected by the Search for Extraterrestrial Intelligence (SETI) Institute, a press statement reveals.

Algorithm finds 8 promising signals that could be of alien origin.

Based on initial results, there is a slight chance the new method may have unearthed non-Earth-based “technosignatures”. That would mean it had achieved SETI’s goal of finding signs of extraterrestrial intelligence.

Astronomers Say They Have Spotted the Universe’s First Stars

A group of astronomers poring over data from the James Webb Space Telescope (JWST) has glimpsed light from ionized helium in a distant galaxy, which could indicate the presence of the universe’s very first generation of stars.

These long-sought, inaptly named “Population III” stars would have been ginormous balls of hydrogen and helium sculpted from the universe’s primordial gas. Theorists started imagining these first fireballs in the 1970s, hypothesizing that, after short lifetimes, they exploded as supernovas, forging heavier elements and spewing them into the cosmos. That star stuff later gave rise to Population II stars more abundant in heavy elements, then even richer Population I stars like our sun, as well as planets, asteroids, comets and eventually life itself.

Life as we know it is carbon-based, but does it have to be this way? There’s another element on the periodic table that shares some of the key properties of carbon but is far more abundant on most planets. I’m talking about silicon. So is there silicon-based life out there?

Meteorites reveal likely origin of Earth’s volatile chemicals

Meteorites have told Imperial researchers the likely far-flung origin of Earth’s volatile chemicals, some of which form the building blocks of life.

They found that around half the Earth’s inventory of the volatile element came from asteroids originating in the outer solar system—the part beyond the that includes the planets Jupiter, Saturn, and Uranus. This material is also expected to have supplied other important volatiles such as water.

Volatiles are elements or compounds that change from solid or into vapor at relatively low temperatures. They include the six most common elements found in living organisms, as well as water. As such, the addition of this material will have been important for the emergence of life on Earth.

Alien Civilizations from Level 1 to Level 7! We’re only at level 0.73!

The Kardashev scale measures a society’s technical development based on its capacity to capture energy. In 1964, the Russian astronomer Nikolai Kardashev proposed this system of measurement. The imagined scale of energy consumption is universal and includes the entire universe. Other proposals have been put forward for updating the scale since 1964, including additional power levels and criteria beyond just power itself. In a study presented at the Byurakan conference, a science gathering whose aim was discussing the Soviet Union’s space listening program for radio astronomy, Kardashev initially proposed the concept of his scale.

Famous Warrior Pharaoh’s Stone Engravings Discovered in an Ancient Egyptian Temple

Part of one of the inscriptions found at Kom Ombo, a temple in southern Egypt. The image at the top of the inscription appears to show the king Seti I with the gods Horus and Sobek. Part of one of the inscriptions found at Kom Ombo, a temple in southern Egypt. The image at the top of the inscription appears to show the king Seti I with the gods Horus and Sobek. (Image credit: Egyptian Antiquities Ministry)A giant stone engraving that fits together like a jigsaw puzzle, found in a temple in southern Egypt, may reveal new information about a pharaoh named Seti I, who launched a series of military campaigns in North Africa and the Middle East after he became pharaoh in about 1,289 or 1,288 B.C., several Egyptologists told Live Science.

The engraving has both drawings and hieroglyphs on it; the engraving mentions an event that happened during the reign of Horemheb, an elite general in King Tut’s army who eventually became a pharaoh.

Archaeologists with the Egyptian Ministry of Antiquities discovered the engraving while conducting a groundwater-lowering project in Aswan; inside Kom Ombo, a temple dedicated to the god Horus and a crocodile-headed god named Sobek. The temple dates back 2,300 years; the engraving may have originally been in an earlier temple, now lost, at Kom Ombo that was located on the same spot as the later temple.
