Gravitational pull of half a sand grain measured in physics breakthrough

The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the quantum realm and a potential Theory of Everything.Continue Re… Continue reading Gravitational pull of half a sand grain measured in physics breakthrough

Hunting spacetime fluctuations could unite Einstein and quantum physics

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. Now, a newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and importantly, outlines a way to test it experimentall… Continue reading Hunting spacetime fluctuations could unite Einstein and quantum physics

How a “supervoid” and modified gravity could solve a cosmic conundrum

One of the biggest cosmological mysteries centers on a discrepancy in how fast the universe is expanding. A new study comes to an intriguing solution by applying a modified theory of gravity and an unsettling “supervoid” that our galaxy resides in.Cont… Continue reading How a “supervoid” and modified gravity could solve a cosmic conundrum

“Pseudogravity” in crystals can bend light like black holes

Scientists in Japan have managed to manipulate light as though it was being influenced by gravity. By carefully distorting a photonic crystal, the team was able to invoke “pseudogravity” to bend a beam of light, which could have useful applications in … Continue reading “Pseudogravity” in crystals can bend light like black holes

“Modified gravity” could rule out both dark matter and Planet Nine

Our solar system officially houses eight planets, but some scientists say there could be a ninth. And that’s not just Pluto aficionados – evidence suggests a huge undiscovered world lurks on the dark fringes out there. Now, a new study has found the ou… Continue reading “Modified gravity” could rule out both dark matter and Planet Nine

Antigravity disproved: Antimatter responds to gravity just like matter

Antimatter has intrigued and confounded physicists for almost a century, and the effect of gravity on antimatter has been a point of disagreement. New research may have settled the debate by finding that antihydrogen atoms, the antimatter counterpart o… Continue reading Antigravity disproved: Antimatter responds to gravity just like matter

3-million-mile-high tsunamis crash down on “heartbreak” star

From strange stars to weird worlds and other odd objects that defy explanation, the cosmos constantly surprises us. Now astronomers have discovered a “heartbreak” star system where tidal waves, three times taller than the Sun, rise and crash on the sur… Continue reading 3-million-mile-high tsunamis crash down on “heartbreak” star

“Quantum gravity” clues could be hiding in the songs of black holes

Of the four fundamental forces of physics, gravity is the one we’re most familiar with in everyday life, but it’s also the only one that can’t currently be explained by quantum physics. Now scientists have outlined a plan to look for signs of quantum g… Continue reading “Quantum gravity” clues could be hiding in the songs of black holes
