This is a repository for all cool scientific discussion and fascination. Scientific facts, theories, and overall cool scientific stuff that you'd like to share with others. Stuff that makes you smile and wonder at the amazing shit going on around us, that most people don't notice.
Post pictures, vidoes, stories, or links. Ask questions. Share science.

I think most people were not even aware a Barrycenter exists.

The link in that post explains it better than I'm able.
The fact that there is a barrycenter, is how we detect planets in other far away galaxies. We look for that little wobble in the parent star, indicating that a planet is tugging at it.
Earlier you said that the sun "orbits" the barycenter of the universe. Technically no object has to orbit another. You also can fall into the object or you can escape the orbit as well though not the gravitational force altogether. And since the barycenter of the universe is a mathematical grid/measurement starting point, it is arbitrary to what mass is being included. And can wildly swing as the result. Bary-anything is just an attempt to put a ruler, a grid to deal extend the "algebra" to the situation under investigation. [Reply]
In a video taken during the shoot on March 18, 2013, Upton can be seen floating through the air as photographers and the crew work to capture the model posing gracefully on the other side of the aircraft. The magazine unveiled the photos online and announced them via Twitter @SI_Swimsuit.
"One small step for swimsuit, one giant leap for mankind," someone adapting astronaut Neil Armstrong's famous words as he stepped on the surface of the moon for the first time, said at the end of the Sports Illustrated video.
ZERO-G passengers experience weightlessness as pilots flying the company's modified Boeing 727 fly in parabolic arcs while thousands of feet above Earth's surface. As the plane tilts its nose and flies on the downslope of the parabola, passengers experience about 30 seconds of weightlessness at a time. For Upton's shoot, the company flew a series of 13 weightless parabolas and four parabolas imitating lunar gravity, according to ZERO-G.
Upton floated through the plane in gold and white two-pieces and a gold lamé zip-up one piece. She also posed in droplets of weightless water while floating upside down in the plane for the magazine's 50th swimsuit issue. The weightless shoot was four years in the making, according to a passengerheard speaking in the Sports Illustrated video.

"So yeah, this happened," Sports Illustrated representatives posted on Twitter from the @SI_Swimsuit profile today.
Upton isn't the only celebrity to fly in ZERO-G's unique brand of weightlessness. Sir Richard Branson, the billionaire founder of commercial spaceflight company Virgin Galactic, took a ZERO-G flight with his family recently. Branson flew with ZERO-G in order to get a taste of weightlessness before Virgin Galactic's suborbital vehicle SpaceShipTwo makes its expected debut later in 2014. [Reply]

Yes, you're right. When I said the sun orbited the barrycenter of the universe, I meant that it orbited the barrycenter of just our solar system. I said it right the first few times, but confused "Universe" with "Solar system" in the post with the gifs. I meant the total center of mass of the planets in our solar system. Not the entire universe.
Technically, I also referenced the barrycenter of the Sun-Jupiter as well, which is different than the planet center of mass as it just compared the masses of two bodies. [Reply]
Everyone know the future of secure communications is using Quantum theories. The problem has been that only scientific labs or huge businesses have enough quantum memory to run the math to encrypt and decrypt.
Now they have figured out a way to not use quantum memory.
