If Atoms Are Mostly Empty Space, Why Do Objects Look And Feel Solid?

Image Credit: Pixabay Guest Author Roger Barlow, University of Huddersfield Chemist John Dalton proposed the theory that all matter and objects are made up of particles called atoms, and this is still accepted by the scientific community, almost two centuries later. Each of these atoms is each made up of an incredibly small nucleus and even

$14 Billion Machine To Introduce Exciting New Phase Of Nuclear Fusion

A New Twist On Fusion Power Could Help Bring Limitless Clean Energy

If it works, fusion power offers vast amounts of

Giant Atoms Could Help Unveil ‘Dark Matter’ And Other Cosmic Secrets

Photo Credit: Tryphon via wikimedia Guest Author Diego A. Quiñones, University of Leeds The universe is an astonishingly secretive place. Mysterious substances known as dark matter and dark energy account for some 95% of it. Despite huge effort to find out what they are, we simply don’t know. We know dark matter exists because of the gravitational

New Insight Into Elusive Antimatter Can Help Unravel Mysteries Of The Universe

Image credit: YouTube TED-Ed   Guest Author Niels Madsen, Swansea University Physicists have believed that the universe is made of both matter and antimatter since the 1930s. While we are well aware of what the physical matter is, antimatter has remained an elusive substance. But that is about to change: our newly-published research on antihydrogen – the antimatter

Controversial New Hypothesis Of Gravity Passes First Test

Photo Credit: Tryphon via wikimedia   Recently, a hotly debated and disputed new theory of gravity, proposed by Delta Institute for Theoretical Physics (Amsterdam) professor Erik Verlinde, has just passed a crucial first test. Its core idea is that gravity is not a real force but is just an effect due to the increasing entropy of the universe.

Watch This Mind Blowing Comparison Of The Size Of Black Holes

Image Credit: YouTube morn1415   Black holes are such reality defying beasts that when Albert Einstein’s equations first predicted the existence of them, he didn’t believe they could actually be real. When you watch this video on the kind of mass compression it takes to create such a matter gobbler, you may still be shocked. I thought I was past being shocked by

“Impossible” EM Drive Passes Peer Review-What Now?

Image Credit: NASA Spaceflight It’s now official- the controversial propellantless engine known as EM Drive really does appear to work. The paper authored by Harold White and other NASA specialists details how they carefully tried to account for many potential sources of error, and they have shown that the EM Drive does indeed work. “Thrust data from forward, reverse, and null suggests
