4 Cool Facts about Gravity

Learning about something that’s always been there seems like a funny thing, but it took ages for humans to understand what causes something to fall to the ground. It may or may not have ever even been an idea that somewhere in the Universe, things may not even fall at all.

It wasn’t until our very own and beloved Sir Isaac Newton made the incredible discovery of gravitational forces, until then, we just assumed things remained on the ground because that’s where they had always been.

The more you think about why your feet stay on the ground, the better you’ll feel about yourself as compared to the aliens who might be living in a world where gravity exists in totally different forms.

Here is a short list of some of the most attractive and interesting facts of gravity, so let’s check out 4 Cool Facts About Gravity and see what the fuss is all about.

Cool Facts about Gravity #4: Weird Gravitational Facts

Many of us know that gravity is a force, but it hates the factor of duality and unlike other forces, it only attracts and does not repel.

Astonishing, isn’t it? The inverse square law of gravity indicates that, technically speaking, it is an infinite force, but why do we fail from realizing it? The word gravity means heavy as it originated from the Latin word of “Gravis”.

Cool Facts about Gravity #3: The Body Mass Relation with Gravity

Gravity has strong effects and relation to the human body. This was actually discovered by the astronauts while in space.

Astronauts’ experience of travelling and living as weightless masses in space indicated that when gravity is not present in our surroundings then our muscles and bones lose their mass.

This is the very reason that when, after being in space, Astronauts come back to Earth and it takes them time to adjust to what normal gravitational forces our planet has in store. Their blood pressure needs to be normalized to live in our place within the nature of gravity.

In 2006 the Astronaut, Heidemarie Stefanyshyn-Piper, collapsed at a welcome-home party when he returned from space. He didn’t acclimate enough to the gravity on Earth versus the gravity he was experiencing in space.

Cool Facts about Gravity #2: Gravity is Lumpy and Tough

If you think, by living on Earth, we are surrounded by a “normal and even distribution” of gravity then you are wrong.

Gravity is uneven in different parts of the World, because Earth isn’t perfectly a sphere, different level of gravitational forces exist in different parts of the World.

Gravitational abnormality or anomaly is witnessed in the Hudson Bay of Canada, pretty regularly. This place seems to have lower level of gravity than the other parts on Earth.

Cool Facts about Gravity #1: Gravity in Space or Near Black Holes

Black holes are considered a few of the very intriguing pieces of nature, where reportedly, not even light, regardless of how fast its speed is, can escape the pull or gravitational force of black holes.

Black holes are present in the center of our galaxy, the Milky Way galaxy and (hypothesized) all other galaxies.

The black hole at the center of the Milky Way is very calm and we have nothing to worry here on Earth. Despite the massive black hole that’s sitting and swallowing light up in super-sized proportions at the center of our galaxy.

As shown in the movie Interstellar, gravity in a black hole is so strong that nothing can cross it and it practically absorbs everything that passes by, within reach of its gravitational influence. It also causes time to warp the closer you get near it and begin your acceleration towards the speed of light.

Because black holes absorb matter faster than the speed of light, and equations show that we (and object) are unable to travel faster than the speed of light, what the hell is going on in the center of a black hole?!?!

It’s only a matter of time until we learn more about gravity and its immaculate force which gives life and things we don’t even know that it offers us.
