HOW MUCH WE KNOW ABOUT OUR UNIVERSE!

It is a common misunderstanding among us that our universe is nothing more than the sun and our 9 planets (which is another mistake, they are 8). Some, with a bit more more knowledge would say that our universe is our galaxy, MILKY WAY.

I am not criticizing any1, you may have all the knowledge about universe but you may not have all of it. Even I dont have any great knowledge, but I am here to share all the info I have.

I'll discuss the details chapter wise and the discussion would be from basic info to somewhat core info.


CHAPTER 1: GRAVITY


Newton in 1600s discovered that every object has a tendency to attract other object. Usually you would say that if the objects attract each other than why aren't you attached to you are screen right now and why aren't you pasted on the wall in front of you? Well believe it or not, but gravity is the weakest force in the universe.

Yes, but despite being so weak, this gravity is the force that has stuck earth and other planets orbiting the sun, and the moon orbiting the earth. Believe it or not but earth's gravity creat a wave on the moon, that jolts the rock of the moon 7 meters. YES A WAVE OF ROCKY SURFACE 7 METER HIGH! and this tide is the only reason known to man that cause the moon to rotate as well!! If there was no gravity pull for the moon then its shape would have been like a rugby ball.



Oh yes, it is the moon, people,  looking like a rugby ball, but its not like it is like a rugby ball, its just an image!!


Gravity varies according to the mass not the size. If you were on the Jupiter, you would feel twice the gravity, you might be able to raise you hand, but not much. Same goes for Neptune, which has 1.5G, where G=9.8m/s2, the grAvity of our planet. Likewise, there is an exoplanet WASP 8B, the planet light year away  from us that has the gravity of 5G, which means that you would feel your skin dangling on your body, and your hair despite being curly, would lay flatout on your head. You may not be able to raise your hands at all, and your face would become very heavy

Below, is professor Brian Cox at a testing center, where he is in a machine that has created 4G gravity and look at his facial expression

He looks a bit disturbed but altogether a bit alright, he said that at 4G he felt his head was very heavy and had problem breathing. Now this is how he looked when he went to 5G

Look at Professor Cox skin, its dangling and according to him it was quite hard to speak and he couldnt see anything at a distance of half a foot, he said that everything was very fogy.

So you see people, if you think that you can go and train at 4G like GOKU (DragonBall Z fans would know what I am talking about), then forget it, you may not be able to raise a hair, forget hands. But I would salute Mr. Brian Cox, for his brave step of getting into this much trouble, just to show us how it feels like being in higher gravity areas.

Oh yeah and one more thing. Do you know which place in our Solar system has the highest gravity and how much is it?

I'll tell you when I return to continue some more info about gravity and our cosmos and influence of gravity in space. Oh and one more thing, if you feel that its boring, then I would like to tell you that I  haven't even started yet. There's a lot more to come.


PEACE People Peace \m/

Oh yeah and one more thing! Do you know that our galaxy is on a collision course!!! :D
