BOULDER- Black holes, time travel and E= mc^2. They are all related to Albert Einstein's Theory of Relativity. How many of us, though, can actually explain any of it? This year, Einstein's theory ...

Many theories are rock-solid: Scientists have just as much confidence in the theories of relativity, quantum mechanics, ...

Textbooks give strange, imprecise explanations of where things happen in quantum mechanics. Consistency with gravity needs a fresh approach.

As the universe expands, it feels like it must be spreading out from some initial point. But a physicist explains why that’s ...

According to Newtonian physics, the gravitational attraction between two masses is proportional to the inverse of the square ...

Journal for General Philosophy of Science / Zeitschrift für allgemeine Wissenschaftstheorie, Vol. 50, No. 1 (March 2019), pp. 13-27 (15 pages) In a way similar to classical mechanics where we have the ...

While the title makes this sound very science-based, this is still a financial planning article. Don’t worry if you haven’t heard of the theory of financial relativity, as it was made up while I was ...

Einstein's theory of general relativity views time similarly to width, height, and length. As such, both time and space can be curved by gravity. This effectively means that time is slower the closer ...

Einstein’s Theory of General Relativity is currently our best approximation of how the universe ticks. But there are holes.

Solar eclipses occasion lots of excitement and pique the public's interest in astronomical phenomena. Eclipses can also expand our understanding of the universe in profound ways. In fact, astronomical ...
