The best explanation we had...
From galaxies to Saturn's rings to our solar system, many celestial objects are flat-out flat. But do you ever wonder why that is -- especially when we live in an ever-expanding, three-dimensional universe?
Henry Reich, creator of the YouTube series MinutePhysics, unravels the mystery of why the solar system is flat in a new video -- just check it out above.
In a galaxy far, far away, two black holes are dancing around each other, drawn together by each others’ immense gravity. Eventually the two may collide, triggering a blast with the power of 100 million star explosions.
That won’t happen for at least 100,000 years, and its effect on Earth will be subtle. The black hole duo is located about 3.5 billion light-years away, but the encounter will send out ripples in the space-time continuum that will allow scientists to better study the theory of general relativity.
A binary star is a star system consisting of two or more stars, orbiting around their common center of mass. Matt Schulz, a PhD candidate, has discovered the first occurence of a binary star where both stars have magnetic fields. The binary star which he discovered is called epsilon Lupi.
