Two theoretical physicists at Goethe University Frankfurt have now found a new solution to Albert…

Jeff Bezos recently shared his vision in an interview with Lex Fridman: a future where a trillion humans populate our Solar System."I would love to see a trillion humans living in the Solar System. If we had a trillion humans, we would have, at any given time, 1,000 Mozarts and 1,000 Einsteins," he said."The only way to get to that vision is with giant space stations. The planetary surfaces are just way too small."A trillion souls for a thousand Mozarts and a thousand Einsteins is a pretty good deal, all things…

A new theory challenges the foundations of modern physics by suggesting that spacetime is classical, not quantum. This theory predicts larger spacetime fluctuations, impacting object weights. Proposed experiments, like measuring a 1kg mass for weight fluctuations, aim to test this groundbreaking concept, potentially revolutionizing our understanding of gravity and spacetime. A radical theory that consistently unifies gravity and quantum mechanics while preserving Einstein’s classical concept of spacetime is announced…

It’s been three years since the Laser Interferometric Gavitational-Wave Observatory (LIGO) went down for some major upgrades. Now, LIGO is finally up and running again, and this time it’s ready to help fully decipher the mysteries of gravitational waves. But what exactly is LIGO, and what mysteries can it help us solve?

Researchers have confirmed a fundamental assumption in physics with unprecedented accuracy — that the various properties of mass, such as weight, inertia, and gravitation, are always equivalent, regardless of the specific composition of the mass involved. This reinforces the equivalence principle, essential to Einstein’s theory of relativity, and addresses a critical point of divergence between classical and quantum physics.Research teams from Leibniz University Hannover and University of Bremen confirm another…

3D position and shape information for each galaxy helped to measure the magnitude of alignment relative to distant galaxies. Credit: KyotoU/Jake TobiyamaScientists have confirmed that intrinsic alignments of galaxies can probe dark matter and dark energy on a cosmological scale, supporting general relativity at vast spatial scales. However, the nature of dark energy and cosmic acceleration remains unresolved.Einstein would nod in approval. General relativity may apply even in the farthest reaches of the universe.Now,…

In the early 1900s, Albert Einstein proposed the theory of general relativity, which challenged everything scientists believed they understood about the universe at the time. Over the years, scientists have questioned whether this theory was true. However, a newly created dark matter map finally gives undeniable proof. We must first look at Einstein’s original theory to fully understand this new development. Before Einstein proposed the theory of general relativity, scientists believed space to be almost…

Scientists using data from the Atacama Cosmology Telescope in Chile have made a detailed map of dark matter’s distribution across a quarter of the sky.First Full-Color Images From Webb Space TelescopeThe map shows regions the distribution of mass extending essentially as far we can see back in time; it uses the cosmic microwave background as a backdrop for the dark matter portrait. The team’s research will be presented at the Future Science with CMB x LSS conference in Kyoto, Japan.“We have mapped the invisible dark…

Researchers used the Atacama Cosmology Telescope to create this new map of the dark matter. The orange regions show where there is more mass; purple where there is less or none. The typical features are hundreds of millions of light years across. The whitish band shows where contaminating light from dust in our Milky Way galaxy, measured by the Planck satellite, obscures a deeper view. The new map uses light from the cosmic microwave background (CMB) essentially as a backlight to silhouette all the matter between us and…

By developing a method to compute correlation functions among fluctuations, they aim to bridge the gap…
