New theory: Gravity can exist without mass, so dark matter does not exist

For centuries, scientists have grappled with the fundamental forces that govern our universe, the most important of which are gravity and, more recently, dark matter. Gravity is the invisible force that pulls objects of mass together and plays a crucial role in shaping the cosmos, from the formation of galaxies to the orbits of planets. … Read more

How game theory can make AI more reliable

A much bigger challenge for AI researchers has been the game Diplomacy, a favorite of politicians like John F. Kennedy and Henry Kissinger. Instead of just two opponents, the game features seven players whose motives are difficult to read. To win, a player must negotiate and forge cooperative agreements that anyone can break at any … Read more

In theory: what would a current-gen upgrade for Red Dead Redemption 2 look like?

It is one of the most baffling mysteries of the current generational era. So many PS4 and Xbox One titles have received remasters or 60fps upgrades and yet one game stands alone… Red Dead Redemption 2. There’s no real reason why developer Rockstar can’t release a vastly improved version of the game for PS5 and … Read more

According to new tree data, the commonly used climate theory is incorrect

This article was reviewed according to Science fact checked peer-reviewed publication trusted source proofread OK! A collage of photos of the Colorado pine (Pinus edulis), also known as the pinyon pine, contributed to SEINet, an NSF-supported resource. New NSF-supported research using tree rings shows that in the case of these trees, the climate envelope theory, … Read more

Combining theory and experiment to shed new light on proton spin

A global analysis of experimental data and Quantum Chromodynamics calculations of the lattice provides insight into the role of the gluons (purple coils) that contribute to the spin of the nucleon. Gluons are manifestations of the. Credit: Jefferson Lab Nuclear physicists have long been working to reveal how the proton gets its spin. Now, a … Read more

Scientists are working on a unified theory of consciousness

The origins of consciousness have plagued the minds of philosophers and scientists for centuries. In the past decade, neuroscientists have begun to map its neural basis, that is, how the brain, through its intricate connections, transforms electrical signals between neurons into consciousness. Yet the field is fragmented, an international team of neuroscientists recently wrote in … Read more

A new theory of quantum gravity could explain the biggest puzzle in cosmology, research suggests

The nearby Andromeda galaxy with older stars highlighted in blue. A new theory of quantum gravity could help explain why more distant galaxies seem to be retreating faster than nearer ones.

A variation on the theory of quantum gravity – the unification of quantum mechanics and Einstein’s general relativity – could help solve one of the biggest puzzles in cosmology, new research suggests. Scientists have known for almost a century that the universe is expanding. But in recent decades, physicists have discovered that several types of … Read more

Scientists prove ‘quantum theory’ that could lead to ultra-fast magnetic computing

A futuristic image of a computer chip

For the first time, scientists have magnetized a non-magnetic material at room temperature, creating a quantum property that they say could pave the way for ultra-fast computing. The ‘switchable’ magnetic field could one day be used to store and transmit information. This was something that was previously only possible at ultra-cold temperatures. The results pave … Read more
