Gifs are one of the coolest things that the Internet has created, especially if kittens. But not only cute gifs that the internet is made.

And now the time has come to see the coolest gifs about science in general, whether involving the universe, physics, astronomy, biology, etc. Check it out and then tell us in comments what your favorite.

<h3>Law of Inertia</h3>To get anything better than the image of the greatest living scientist today: Neil deGrasse Tyson explaining the 1st Law of Newton, the law of inertia. According to this law, every body in motion tends to stay in motion until it encounters an opposing force of action that prevents it from continuing its movement.
Knowing also that no body "win" rate of nowhere, Neil can drop the bowling ball without fear of it back in his face. This is because the string that holds the ball and makes the pendulum motion will not be more powerful than anything the contrary, the Law of Inertia says with air friction and gravity, the ball will get less and less close his.

<h3>Gravity law</h3>And speaking of gravity, the next example is it. According to explanations and theories that account to explain the universe, gravity is one of the four fundamental forces that make things work the way they are. And that goes way beyond playing an apple up and wait for her to fall. It is because of her that things have weight on Earth. See, here on Earth. That's why in space, things work as follows:

One of the first well-grounded descriptions of gravity was Newton when he explained that the force of gravity is directly proportional to the masses of the bodies involved and inversely proportional to the square of the distance between them. Understood? Me neither. Since then, the most accurate description of gravity was given just over 100 years, in 1915 by Einstein explaining a complex phenomenon that involves the result of space-time curvature and regulating the movement of inert objects.

From cosmology standpoint gravity has an important role to make the mass dispersed some point this universe agglomerate in small dots known as planets, meteors, stars, etc. She still has the important function to keep the planets in their orbits due.

<h3>Jupiter and its moons</h3>
And speaking of orbit and all, look how are the orbits of some of the (gasp) 67 moons of Jupiter, the gaseous planet. Yes, the largest planet in our solar system (has 2.5 times the mass of all other together) and fifth in sun proximity has at least 67 natural satellites, some of which are known and described hundreds of years ago by Galileo Galilei, as Ganymede, the largest satellite in the natural system (higher even than the planet Mercury).

Jupiter is composed mostly of hydrogen and helium, so it is called gaseous planet. Scientists suspect that at its core can even be heavier elements, but all we see is winds, storms and winds more. The Great Red Spot, which you can see in the center of the planet in the gif below, has winds of up to 600 km / h, has had sufficient diameter to accommodate 2 Earths and there at least since the seventeenth century, when it was recorded by first time.

<h3>The sun</h3>
Even being so huge, Jupiter is less than one thousandth of the mass of the sun, our next character. main character, by the way, because if not for him we would not be here. The sun is our star and one that allows for the development of life on Earth. He also has 99.86% of the mass of our solar system. Yes, the rest of planets, stars, etc. summing just over 1%.

Only the sun can be a little mean sometimes. All because of the explosions that happen all the time and from time to time can destroy all our lines that make up the system telephone system, satellites, etc. The last major explosion occurred and caused damage was in the nineteenth century and was responsible for leaving the United States without communication with Europe for weeks. NASA feared a blast in 2015, but for our lucky nothing happened too.
The gases that emerge from these eruptions reach over 1.5 Mihao degrees centigrade and form bonds that reach hundreds of times the size of the Earth. These links contain so much mass expelled weighing somewhere around 10 billion tons. The last stage is when the extruded material around the sun at a speed of 100 kilometers per second.

<h3>Size of the universe</h3>
But even so the sun does not seem so great when we get to see the rest of the things that exist throughout the universe. Below we can see a comparison shows that, in the following order:
<b>Earth</b> - Mass 5,972x10 R 24, or 5.972.000.000.000.000.000.000.000 Kg;
<b>Sun</b> - has the mass of 332,900 Earths and a diameter of 1.5 million kilometers (within the sun fit more than 1 million Earths);
<b>Eta carinae</b> - Star more "doughy" we know, has between 100 and 150 times the sun's mass, and more than 5 million times the sun's size;
<b>Betelgeuse</b> - With 20 times the mass of the sun, it is 300 times greater than Eta Cinae
<b>VY Canis Majoris</b> - has the size of more than 1 BILLION suns and 17 times its mass. It is the largest known star. Think small? Imagine that a commercial plane, an average of 900 km / h, it would take a measly 1,100 years to circle the star.
<h3>Planet Earth</h3>
Finally, he missed only talk about our home, the Earth, our great planet round and blue. But actually it is not as round as well. It has the form of a geode and we are thinking that it is round because of the large volume of water distributed by almost all our surface.
The radius is greater in the equator than at the poles because of the effects of Earth's rotation in the long run. Furthermore, as the mountains have more mass than a valley, e.g., these deformations cause gravity is stronger near mountains, which changes the final form of our planet.

And speaking of Earth, just wanted to show the gif below that shows the dance of stars and planets in our horizon thanks to the rotation. And just remember, this is the movement that the Earth does on its own axis (each lap is 1 day). Not to be confused with translation, which is the movement around the sun (each lap is 1 year).

So, you liked the gifs? They are not as cool as the kitten, of course, but it gives to get a sense of things that until then seemed very distant to us, agree?
