“Dead” Idea From the 1800s Could Finally Reveal Why the Universe Exists Japanese physicists have revived Kelvin’s old idea of cosmic knots, showing how these tangled fields might explain why matter won the universe’s first great battle over antimatter. In 1867, Lord Kelvin...

Einstein’s overlooked idea could explain how the Universe really began Researchers have unveiled a new model for the universe’s birth that replaces cosmic inflation with gravitational waves as the driving force behind creation. Their simulations show that gravity and quantum mechanics may alone explain the structure of the cosmos. This elegant approach challenges traditional Big Bang interpretations and revives a century-old idea rooted in Einstein’s work.

A new model suggests the universe's birth was driven by gravitational waves rather than cosmic inflation. This theory, inspired by Einstein's ideas, could reshape our understanding of the cosmos. What are your thoughts on this groundbreaking approach? 🌌🌀 #Cosmology #Einstein #UniverseOrigins

A New Theory of the Universe’s Origins Without Inflation How exactly did the universe start and how did these processes determine its formation and evolution? This is what a recent study published in Physical Review Research hopes to address as a team of researchers...

SPHEREx will create a complete 3D map of the celestial sky every 6 months, measuring the distance to 450 million galaxies.

It will detect traces of cosmic inflation—when the universe expanded a trillion-trillionfold in a fraction of a second after the big bang.

Life May Have Emerged a Cosmic Eyeblink after the Big Bang New simulations suggest that habitable worlds could have begun forming only 200 million years after the big bang

8/8 A mind-bending possibility: some water molecules in your drinking glass may have formed over 13 billion years ago in the expanding shockwave of one of the universe's first stars.

Infrared image data from the Spitzer Space Telescope showing a diffuse glow possibly from the first generation of stars. Gray areas indicate where foreground stars have been digitally removed. The image depicts the infrared background light, with bright patches possibly originating from clusters of the first stars, which were hundreds of times more massive than our sun.

Photo of a book with a red cover and a black geometric pattern on a white background skirting around the border. The Loeb Classical Library has reproduced it. The book, of course, is Lucretius "On the nature of things". It was translated by W. H. D. Rouse and revised by Martin F. Smith. It is just a photo off the internet as they still have my copy!!

🧪 🍎

When you encounter a young person, introduce them to Lucretius' De Rerum Natura...

... and now they possibly love it even more than you do 😍🥰
