space time

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.
We all are familiar with the force of gravity. But, where do the gravitational waves fit in the picture?
Now, the two stars that make up the outer part of the Big Dipper’s bowl will always point you directly to the north star
You've likely heard the saying: Looking out into space is the same as looking back in time. But what does that mean, scientifically speaking? It turns out that astronomers can observe stars and planets as they were in the past since it takes light quite some time to travel from those distant celestial objects all the way to Earth -- and the farther an object is, the longer it takes for the light to reach us. How is that even possible? HuffPost Science's Jacqueline Howard reports.

The prospect of making a discovery that would not only defy common sense but also overturn centuries of scientific thinking
It may come as a surprise that in modern physics, there exists a scale below which the very notions of length and space cease to exist. This is known as the Planck length, named after the German physicist Max Planck.
Still, says study coauthor Dentcho Genov of Louisana Tech University in Ruston, the team’s microchip model “may hold the
What it comes down to, then, and what science helps us consider, is that there is an omnipotent, omnipresent force in the universe that creates everything we see, touch, taste and experience.
The fascination with π is so universal that in 1998 film director Darren Aronofsky even created a psychological thriller with that title. Here I want to tell only a few more π stories that are perhaps less known outside the circle of true aficionados.
A new study of one of the universe's fundamental constants casts doubt on a popular theory of dark energy, scientists say
In his general theory of relativity, Einstein described space-time as fundamentally smooth, warping only under the strain
The Big Bang is, without doubt, one of the greatest achievements of human civilization. So why then are so many scientists waiting so expectantly for its immanent demise?
If life were like a movie and we were able to slow it down we would see the blank spaces between each frame, between each moment, between each change. Kabbalah is the system where we try to see those spaces.
(There is another outburst of confusion in the gallery.) Albert Einstein: Ya, ya. I can concur with this, except that I have
I'm not a scientist or anything, but I've seen a lot of movies on the Discovery Science Channel, and I'm pretty sure my apartment is some sort of vortex or wormhole or portal to another dimension.
