Nature’s Warning: Early Signs in Marine Life That Predict the Next Mass Extinction

by
SciTechDaily

Researchers have used a detailed global dataset of foraminifera fossils to study shifts in marine community structures before mass extinctions, providing an early warning system for future biodiversity losses due to climate change. Led by Anshuman Swain and Adam Woodhouse, the study highlights the importance of monitoring ecological changes to predict future extinctions, potentially shaping … Read more

Wild new study suggests gravity can exist without mass

by

What is gravity without mass? Both Newton’s revolutionary laws describing its universal effect and Einstein’s proposal of a dimpled space-time have led us to think of gravity as falling solely within the domain of matter. Now a wild new study suggests that gravity can exist without mass, easily eliminating the need for one of the … 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
