General Relativity

Why Space and Time Might Be an Illusion

George Musser | Posted 04.26.2016 | World
George Musser

Whereas general relativity took a single genius (Einstein) a decade to create, that deeper theory -- known as a quantum theory of gravity -- has flummoxed generations of geniuses for a century.

Ripples in the Cosmic Pond

I am now exclusively occupied with the problem of gravitation, and hope, with the help of a local mathematician friend, to overcome all the difficulti...

Gravitational Waves: Why Are Scientists Celebrating?

Bryan Gaensler

There have been many scientific highlights of physics and astronomy in recent years: the Higgs Boson, landing a probe on a comet, and an amazing fly-by of Pluto. But all this is dwarfed by what has been announced this week. A new era of science has begun.

Emergence: A Powerful but Little Known Notion

Lee Smolin in his book, "The Trouble with Physics" first brought my attention to the concept of emergence. This is a very powerful approach to physics...

Gaga for Gravitation

David Kaiser | Posted 11.23.2015 | Science
David Kaiser

Gravitation proved to be far more than its jumble of equations, nonlinear structure, and famous text-boxes. Though several newer textbooks have displaced the book from graduate students' syllabi, none has rivaled the book's cross-over appeal.

Einstein's Piano

This month marks the 100th anniversary of Albert Einstein's theory of general relativity. Amid all the celebrations and conferences, it is easy to forget about the real human being who actually did it. But if you live in Princeton, and his piano is in your living room, he is always present.

Discovering Propellantless Propulsion (1)

For someone who is determined to get propellantless propulsion off the ground, I worry that there isn't enough experimental research to make propellantless propulsion a reality sooner rather than later.

Happy Birthday Einstein! 100 years of General Relativity

Dr. Sten Odenwald | Posted 09.30.2016 | Science
Dr. Sten Odenwald

On November 25, 1915, Albert Einstein finally announced the complete mathematical details of his General Relativity Theory in the last of a series of four papers, but gravity and the nature of space itself, remain as mysterious today as they were back then.

Stephen Hawking's New Black Hole Idea May Blow Your Mind

How do you escape from a black hole? Stephen Hawking has an idea. In front of a crowd of scientists and reporters at KTH Royal Institute of Technology...

Do We Really Know What's Real? The Most Optimistic Answer Is Maybe

Deepak Chopra | Posted 08.03.2016 | Education
Deepak Chopra

Three great unsolved mysteries remain, and they are the same riddles asked by ancient Greek philosophers: What is the universe made of? Where did the universe come from? How do we know what's real?

Bad, Bad, Bad Physics

Benjamin T. Solomon | Posted 07.28.2016 | Science
Benjamin T. Solomon

All physics is error prone and then there is bad physics. I deconstruct one of the most controversial antigravity experiments on the internet, so that we as a general population are able to differentiate misinformation from the real thing.

Strings Are Dead

I forecast that both string and quantum gravity theories will be dead by 2017.

The Feasibility of Interstellar Propulsion

Benjamin T. Solomon | Posted 05.28.2016 | Science
Benjamin T. Solomon

The question we should be asking is not, can we travel faster than light (FTL) but how do we bypass LFT? Or our focus should not be how to travel but how to effect destination arrival.

Toward a Quantum Theory of Gravity? (Part 2)

Mario Livio | Posted 07.02.2014 | Science
Mario Livio

One of the key goals of a quantum theory of gravity is to describe black holes as complex but self-consistent quantum systems. The problem is that as physicists have attempted to do just that, they have encountered the so-called "information paradox."

Cosmos Peacefully Settles the Score

Community Advocate Stuart | Posted 06.02.2014 | Science
Community Advocate Stuart

The message of Cosmos to people of faith is that divinity is a human exercise; that what makes us special isn't a book; that despite our ultimate insignificance, we can still understand the nature of the universe and our place in it; and that it is not a betrayal of faith to ask questions.

Big Discovery May Help Bring 'Theory Of Everything' | Mike Wall | Posted 03.24.2014 | Science

The discovery that the universe really did expand at many times the speed of light immediately after the Big Bang should bring physicists slightly clo...

Newfound Stellar Trio May Put Einstein Theory To The Test

In a cosmic coup, astronomers have found a celestial beacon known as a pulsar in orbit with not one, but two other stars. The first-of-its-kind trio c...

Dark Matter and Worst Packings

Frank Morgan | Posted 07.28.2013 | Science
Frank Morgan

Just as Einstein's theory of General Relativity explains gravity as curvature of the universe, Hugh Bray similarly incorporates dark matter into the geometry of the universe, altering not just the "Riemannian metric" but also the "connection."
