Here on Planet Earth, we humans take gravity so for granted that it required an apple falling from a tree to produce Isaac Newton’s theory of gravitation. But gravity, which pulls objects together in ratio to their mass, is about much more than just fallen fruit. So keep reading for several of the weirdest facts about this universal force.
1. Some areas of Hudson Bay and the nearby regions of Quebec are “missing” gravity. This is one of the parts on earth with very low gravity. – Source
2. On Saturn’s largest moon Titan, the gravity is so much low and the atmosphere is so thick that humans could easily fly through it by flapping “wings” attached to the arms. – Source
3. Liquid helium can drift through microscopic holes, up walls against gravity and has almost zero viscosity and. – Source
4. Einstein, about century ago, proposed in an inch long equation that “Gravity” doesn’t pull. Instead space actually pushes. “Gravity” is only the seeming effect of the curves in space. G = 8 π T. – Source
5. In zero gravity, a candle’s flame is blue and round. – Source
6. Many zero-gravity scenes in the movie Apollo 13 are basically genuine. The crew recorded 4 hours of material in 612 parabola flights. – Source
7. The tallest likely mountains on a neutron star can only be about 5mm tall because their enormous gravity. – Source
8. NASA cannot bring birds into space because birds need gravity to swallow. -Source
9. Humans generally get the desire to pee when the bladder is just 1/3 full. But in zero gravity, the desire doesn’t kick in until the bladder is nearly full. When astronaut John Glenn circled the Earth, his only urination was 27 ounces, seven ounces more than the capability of the regular human bladder. – Source
10. Gravity Probe B has the most perfect spheres ever made by human beings. If GP-B’s gyroscopes were inflated to the size of the Earth, the highest mountain would be only eight feet tall. – Source
11. When melting glass in space, zero gravity upsurges the viscosity and you can make glass with chemicals other than silica. – Source
12. Due to differences in local gravity, a pendulum clock precise at sea level will lose around 16 seconds per day if relocated to an altitude of 4000 feet. – Source
13. Not only do we see distant stars as they were thousands of years ago, but we also still experience their gravity from thousands of years ago, and not from where they are now. We even experience the pull of gravity from stars that have burned out. - Source
14. A neutron star’s gravity bends light so forcefully that more than half of its exterior is visible from a given point of view. In several cases the gravity can be so great that the whole surface would be visible from certain vantage points. – Source
15. Did you know that there is an empty point in space where the gravity from the Planet Earth and the Sun is equal, and objects can orbit it as if there was something present there? – Source
