this was originally meant to be a physics blog but i find myself posting more about biology related stuff - excuse my inner plant nerd but i like physics too, so:

*cough cough* SPAGHETTIFICATION! a phenomenon where you can become stretched like spaghetti if you enter a black hole.

it’s also known as the tidal effect, and is generally used to describe the vertical stretching or compression of an object into a noodle-like shape in an extremely strong and non homogenous gravitational field.

by non homogenous i just mean that the gravitational field is not the same everywhere, but consists of irregularities. (it is non-uniform)

anyways, a very common example of this is when we’re talking black holes- if i threw you into a black hole, or you happened to fall into one, the gravitational field on one end of your body would be stronger than the other.

this gravitational gradient would mean as you fell, getting closer and closer to the event horizon, your body would become extremely stretched until it would become very very compressed. like spaghetti. but don’t worry, by that time you’d already be dead.

this only happens because of the sheer strength of a black hole’s gravitational field. it’s not really because of its size - but its density. there are lots of objects close or even larger than some black holes, the mass of a black hole is so concentrated in a small area that it absolutely maximises its gravitational pull, which is why not even light can escape it.

this is just one of the relativistic effects of gravity differences, and there are so many cooler ones! for example, pancake detonation.

so stay away from black holes, or you could become stretched like spaghetti or flattened like a pancake.

Aurora on Saturn captured by the Hubble Telescope

Stepping out on the front porch. Astronaut David Scott opens the hatch to check out the view during Apollo 9, March 1969. In this pic taken by fellow astronaut Rusty Schweickart, ‘Gumdrop’, the Command Service Module is docked with ‘Spider’, the Lunar Module. A9 was the 1st flight incorporating all Apollo spacecraft components. The 10 day mission was the 2nd launched by a Saturn V rocket.

Sharp Nebula Shot!

30 years ago today, Eileen Collins became the first woman to pilot the space shuttle, piloting Discovery on its STS-63 mission. She later also became the first woman to command the space shuttle. She reflects on her career in #ASQ: s.si.edu/3SJEOQq

Artemis II Stacking Operations Update

Teams with NASA’s Exploration Ground Systems Program continue stacking the SLS (Space Launch System) rocket’s twin solid rocket booster motor segments for the agency’s Artemis II mission, inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida. Currently, six of the 10 segments are secured atop mobile launcher 1 with the right […] from NASA https://ift.tt/1uI7Dtq
