14-billion-years-later:

On why you never really touch anything.

Although this may not be remarkable to most of you it’s something that blows my mind everytime I think about it. Right now you’re probably sitting down on a chair or something, but in reality you’re actually hovering just slightly above it. The distance itself is tiny around about 1/10000000000 of a metre or one Angstrom for those in the know. But why? Well it all has to do with our good old friend, electro-static repulsion. You see the electrons that make up you and the electrons that make up the chair have a repulsive effect, which means they can only ever come within a certain distance of each other but never touch. This effect is also the reason behind why we can’t walk through walls, despite as you may know matter being almost entirely empty space. Everything that feels solid to you is really just an illusion made by the forces between electrons.

this just blew my mind

i remember my chemistry teacher telling us that in high school. i still think about it sometimes and it blows my mind all over again.

Spewing Flare Event

The Sun popped off an M-Class (moderate level) flare on Sept. 25, 2011 that sent a plume of plasma out above the Sun, but a good portion of it appeared to fall back towards the active region that launched it. The activity in the video clip here, seen in extreme ultraviolet light, covers just 3 hours. With an image every minute, every nuance of graceful motion can be observed in wonderful detail. The bright flash shows the flare itself erupting. Since this event, this active region has been the source of several large flares and many lesser ones that have caused geo-effective storms on Earth as it has rotated around towards facing us.

This human heart has had the fat and extra tissue was removed, leaving pure angel-hair blood vessels to make up its shape.
