Quantum Gravity: Where Einstein’s Theory Breaks Down
Einstein Field equations explained intuitively and visually: Isaac Newton changed our paradigm by connecting earthly gravity, with the movement of heavenly bodies. He formulated an equation that is still used today - the law of universal...

String Theory vs. Loop Quantum Gravity: Competing Paths to Quantum Gravity
The gauge bosons of the standard model of particle physics are responsible for 3 of the 4 known forces in the universe. A force is conferred is through the exchange of virtual bosons. So for example in electromagnetism, an exchange of...

Are Real Warp Drives Possible? Exploring New Scientific Proposals
In a recent paper published by Applied Physics, authors Alexey Bobrick and Gianni Martire, outline how a physically feasible warp drive could in principle, work, without the need for negative energy. I spoke to them. They had technical...

What Happened to Antimatter? Understanding Baryogenesis
SUMMARY: Why are we here? Why is there something instead of nothing. Part of the answer is rooted in physics. Matter is not the simplest thing there could have been. The simplest thing In physics is nothing, the emptiness of spacetime....

Could Dark Energy Be Made of Particles? Exploring Quintessence
Dark energy is different than dark matter. They are both labeled dark because we don’t know what they are. Dark matter does not absorb, reflect or emit any light. It is inferred to exist only because of its gravitational effect on...

Can Life Exist in a Two-Dimensional Universe?
We have 3D + 1D of time. Why aren’t there 4 dimensions or 2 dimensions? Can life exist in the 4th dimension? Is there something special about three dimensions that makes life possible? This is the question that But maybe our thoughts are...

General Relativity Explained with Simple Visuals
SUMMARY Albert Einstein was ridiculed when he first published his theory. People thought it was too weird and radical to be real. Einstein wasn’t satisfied with his theory either, because the theory did not apply if Gravity was present...

Quantum Holonomy Theory: A New Take on the Limits of Reductionism
Does a final theory exist that can end our reductionist probing into ever shorter distances? Or is there no end to reductionism? There should be an end point because as the object of our measurement gets small enough, the high energies...

How Scientists Simulated a Wormhole in the Lab
A quantum wormhole was created by a team of physicists led by Maria Spiropulu of CalTech. But this was not a wormhole in spacetime, but a quantum holographic wormhole created inside a quantum computer. The two main theories that describe...

Dark Energy and Black Holes: A Hidden Connection?
SUMMARY: Are black holes the source of dark energy? A new study by Farrah et al, published in February of 2023 claimed to have found a solution to dark energy, showing a connection with supermassive black holes. What is dark energy? It's...

How the Universe Breaks the Law of Energy Conservation
SUMMARY The law of energy conservation may be the most fundamental law in physics. It says that overall energy is always conserved. It can never be created nor destroyed - it can only change form. But this law is probably violated by our...

Could Time Be an Illusion?
SUMMARY What if time is not real, but an illusion? Isaac Newton believed time was absolute and ticked at the same rate for everyone, everywhere. But Albert Einstein shattered that view with the theory of relativity. He showed that time...

The Alcubierre Drive: Is Warp Speed Scientifically Possible?
Alcubierre warp drive - faster than light travel? Is Warp speed possible? Enterprise from Star Trek can go 9000 times the speed of light. By comparison, the fastest manmade object, the Juno probe goes 0.0002 times the speed of light. At...

Black Holes Are Even Weirder Than You Thought
Karl Schwarzschild crafted the first exact solution to Einstein's equations of general relativity. He found that as gravity increased around an object, there must be a point where even light could not escape. He theorized black holes.

Anti-Gravity: the Force that's Tearing Space Apart
SUMMARY What if gravity repelled instead of attracted? Repulsive gravity may have shaped the entire history of our universe. For centuries gravity was defined by Isaac Newton’s Law of Universal Gravitation which said, “every object in...

An Impossible Information Paradox in Black Holes Seems to Break Physics
SUMMARY In 1976, Stephen Hawing proposed that Black Holes, do something impossible according to the laws of quantum mechanics. They destroy information. This is a paradox because information should be conserved in the universe. If it is...
