MOND vs. Dark Matter: Research suggests that the rotation curves of galaxies remain flat indefinitely

by

The main technique Mistele used in his research, gravitational lensing, is a phenomenon predicted by Einstein’s general theory of relativity. As part of the research, Mistele plotted the so-called Tully-Fisher relationship on a map to highlight the empirical relationship between a galaxy’s visible mass and its rotation rate. In a discovery that challenges conventional understanding … Read more

Dark matter decoded: how neutron stars could solve the universe’s greatest mystery

by
SciTechDaily

A recent study from the ARC Center of Excellence for Dark Matter Particle Physics suggests that neutron stars could play a crucial role in understanding dark matter. The study found that when dark matter particles collide into neutron stars, they can quickly heat these stars, potentially making them observable with future astronomical technologies. This rapid … Read more

Gravity without mass is a new explanation for the inability to find dark matter

by

A new explanation for why we haven’t found dark matter suggests it doesn’t exist. Instead, the author thinks we have misunderstood gravity. He is not the first to suggest this, but the new proposal, of gravity without mass, created by topological defects in space-time, is particularly novel. Dark matter was first proposed in 1932, based … Read more

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

by

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

Gravity without mass? New study challenges the existence of hypothetical dark matter – The Debrief

by
gravity

A recent study that poses new challenges to the existence of dark matter suggests that gravity can exist even in the absence of mass. Although all life on Earth experiences its effects every day, gravity remains one of the great mysteries of modern physics. Now, a new study published by Dr. Richard Lieu of the … Read more

The enormous ‘El Gordo’ cluster of galaxies suggests that dark matter is colliding with itself

by
A view of space with blue and pink hazes overlaying lots of stars and galaxies.

Strange behavior in a huge cluster of merging galaxies could be explained if dark matter, the universe’s most mysterious stuff, can collide with itself. However, the most favored model of cosmology at the moment is the Cold Dark Matter (CDM) model – and it suggests that dark matter, which is effectively invisible because it does … Read more
