Your Body Is An Incredibly Bizarre Machine.

DIY organization Autonomous Space Agency Network just sent a Trump protest 90,000 feet in the air. And it didn’t even cost that much to do it.

NASA astronaut Peggy Whitson becomes first woman to command ISS twice

NASA astronaut Peggy Whitson achieved a new milestone at the International Space Station on Sunday, when she became the first woman to command the ISS twice.

Whitson is replacing astronaut Robert Shane Kimbrough, who will depart the space station Monday.

“Up here we don’t wear shoes, but Shane is leaving me some pretty big socks to fill,” Whitson said during a live broadcast as she assumed her new position. Read more. (4/9/2017 3:40 PM)

Cristobalite is a silica polymorph that is thermodynamically stable only at temperatures above 1470°C, up to the melting point at 1705°C, at atmospheric pressures. It commonly metastably persists or even forms at much lower temperatures in silica-rich volcanic and sedimentary environments. It can form crystals in cavities, probably vapour-deposited, or spherulites in obsidian or other silicic volcanics.

Hematite is rather variable in its appearance - it can be in reddish brown, ocherous masses, dark silvery-grey scaled masses, silvery-grey to black crystals, and dark-grey masses, to name a few. What they all have in common is a rust-red streak.

As close as you will ever be to a nuclear explosion

The Magnus Effect - When a small amount of spin is added to a dropped object, the object moves forward

i think it’s a universal truth that everyone in our generation takes pluto’s losing its planetary status as a personal offense

Why not just buid a solar panel around the sun to solve all energy problemss?

Behold the Dyson Sphere

Dyson sphere is a hypothetical mega-structure that completely encompasses a star and captures most or all of its power output.

Over the years many variants have been explored:

The simplest such arrangement is the Dyson ring, in which all ‘energy harvesting structures’ share the same orbit.

Add multiple Dyson ring structures and you will get a Dyson swarm.

Now what if you didn’t like a consistent orbit for your structures, you could employ a solar sail to continuously modify its orbit( called a statite ).

Such an arrangement would be known as a Dyson Bubble

Then there is the fictionally popular version - The Dyson Shell, where a uniform solid shell of matter just encapsulates the entire star.

And many many more. But you get the gist.

Could there be Dyson Spheres out there?

When scientists were monitoring the brightness from some stars, they found that it fluctuated in some odd ways like so:

                          Brightness v/s time for KIC 8462852

It is common for such dips to occur since when a planet eclipses a star, there would a drop in the brightness observed from the star.

                       Brightness v/s time for a binary star system

But what was baffling was the duration and period of occurrence of these dips.

Although the main line of rationale remains as asteroid impact remnants or interstellar collisions causing these aberrations in data.

But to say that these could the signs of an alien civilization does remain to be the more entertaining interpretation.

Great Question. Thanks for asking !
