Solar System Movement in 3D

The true helical/spiral movement of the solar system through the galaxy is not on a single plane; a circle or an ellipse! This spiral is caused by the expansion of space and the movement of our galaxy relative the rest of through space.

Searching For Other Earths

Findings by the Kepler telescope, which NASA launched into space in 2009, have led University of California, Berkeley, astronomers to estimate that in our Milky Way galaxy alone there are 40 billion planets similar to Earth, both in size and temperature. Now scientists are trying to figure out which of these exoplanets might have water, the basic ingredient of life.

Space-Time and the Speed of Light | Einstein’s Relativity

Special relativity is a theory of the structure of spacetime. It was introduced in Albert Einstein’s 1905 paper “On the Electrodynamics of Moving Bodies” (for the contributions of many other physicists see History of special relativity). Special relativity is based on two postulates which are contradictory in classical mechanics:

1. The laws of physics are the same for all observers in uniform motion relative to one another (principle of relativity),
2. The speed of light in a vacuum is the same for all observers, regardless of their relative motion or of the motion of the source of the light.

What is Space?

Space. It separates you from me, one galaxy from the next, and atoms from one another. It is everywhere in the universe. But to most of us, space is nothing, an empty void. Well, it turns out space is not what it seems. From the passenger seat of a New York cab driving near the speed of light, to a pool hall where billiard tables do fantastical things, Brian Greene reveals space as a dynamic fabric that can stretch, twist, warp, and ripple under the influence of gravity. Stranger still is a newly discovered ingredient of space that actually makes up 70 percent of the universe. Physicists call it dark energy, because while they know it’s out there, driving space to expand ever more quickly, they have no idea what it is. 2012

Einstein’s Big Idea

E=MC² Everyone’s heard of it, but what does it mean? And why did it change the world. A dramatization of how an obscure young patent clerk, Albert Einstein, came up with his shattering discovery that the realms of matter and energy are inescapably linked.
