The animation shows a ball dropping from 1 kilometer (0.6 miles) to the surface of each object, assuming no air resistance. You can compare, for example, that it takes 2.7 seconds for a ball to drop that distance on the Sun, while it takes 14.3 seconds Earth.

A 1 Kilometer "Ball Drop" On Solar System Bodies
This animation shows a ball dropping from 1000 meters to the surface of each object, assuming no air resistance. This should give an idea for the pull you would feel on each object.
It might be surprising to see large planets have a pull comparable to smaller…

The root of today’s quantum revolution was John Stewart Bell’s 1964 theorem showing that quantum mechanics really permits instantaneous connections between far-apart locations.
We take for granted that an event in one part of the world cannot instantly affect what happens far away. This principle, which physicists call locality, was long regarded as a bedrock assumption about the laws of physics. So when Albert Einstein and two colleagues showed in 1935 that quantum mechanics permits “spooky action at a distance,” as Einstein put it, this feature of the theory seemed highly suspect. Physicists wondered whether quantum mechanics was missing something.
How Bell’s Theorem Proved ‘Spooky Action at a Distance’ Is Real

The Entire ISS Just Spun Around as New Russian Module Malfunctioned After Docking
A new Russian space-station module malfunctioned after it docked on Thursday. The module, called Nauka, starting unexpectedly firing its thrusters — which moved the entire station out of position.

Fossil discovered in northwestern Canada could rewrite the early history of animal life — but some palaeontologists are not convinced it’s real.
Most major groups of animals — including arthropods, molluscs and worms — first appear in the fossil record during the Cambrian explosion, 541 million years ago. But according to a paper published in Nature1, sponge fossils from northwestern Canada could be 350 million years older, significantly pushing back the date of Earth’s earliest-known animals.
