Fact : Do you know ? Gravity is almost equal at all places of earth crust but still there are some exceptions.
Do you know there is less gravity in few areas of Canada with respect to other parts of earth.
In the 1960s, scientists began to chart Earth’s gravitational fields. You would expect that gravity be the same across the world. It’s not like you feel incredibly heavy in the United States while you practically float around in South America. You always feel the same gravitational pull.
However, they found that gravity actually did vary. In Canada, there are certain areas with less gravity than normal. The Hudson Bay, for example, is “missing” gravity.
There are two theories as to why this may be true.
1. One theory cites convection as the cause. Convection pulls the Earth’s plates downward, which decreases the mass in that area and decreases the gravity.
2. The other theory cites the Laurentide Ice Sheet as the cause. The Ice Sheet melted 10,000 years ago and left a huge indent in the Earth, which could mess with the gravity.

Fact : Do you know ? What happens if you could jump all the way through a hole in the earth to other side.
What if you could jump all the way through a hole in the earth to other side .
The simple answer is, theoretically, yes. First, let us ignore friction, the rotation of the earth, and other complications, and focus on the case of a hole or tunnel entering the earth at one point, going straight through its center, and coming back to the surface at the opposite side of the planet. If we treat the mass distribution in the earth as uniform, one would fall into the tunnel and then come back up to the surface on the other side in a manner much like the motion of a pendulum swinging down and up again. Assuming that the journey began with zero initial speed (simply dropping into the hole), your speed would increase and reach a maximum at the center of the earth, and then decrease until you reached the surface, at which point the speed would again be zero. The gravitational force exerted on the traveler would be proportional to his distance from the center of the earth: it’s at a maximum at the surface and zero at the center. The total time required for this trip would be about 42 minutes. The speed of our traveler at the center of the Earth would be 7,900 meters a second. If there were no friction, there would be no energy loss so our traveler could oscillate into and out of the tunnel.
This trip could not take place in the real world for a number of reasons, including the implausibility of building a tunnel 12,756 kilometers long, displacing all of the material in the tunnel’s proposed path, and having the tunnel go through both the earth’s molten outer core and its inner core, where the temperature is about 6,000 degrees! It would be much easier to build such a tunnel in a small asteroid. Interestingly enough, for a tunnel that reaches from one point to another point on the earth’s surface but does not pass through the center of the planet, the travel time would still be about 42 minutes. The reason for this is that although the tunnel is shorter, the gravitational force along its path is also decreased as compared to that of a tunnel that goes through the center of the planet, which means you would travel more slowly. Because the distance and the component of gravity decrease by the same factor, the travel time ends up being the same.

Fact : Do you know ? What we had done to this beautiful world of ours.
We humans are a part of planet earth, just like animals, plants, land, oceans, mountains, rivers, etc.
Together we make this world look more beautiful.
But in recent times, something is happened in this ecosystem, there are number of problems arrived together like terrorism, deforestation, global warming, wars, etc.
I started to look at the roots of the problem.
So first of all I looked at animals to find out there role in this situation, they came out clean.
Then I looked at plants, they turn out clean too.
In same way land, oceans, mountains, rivers all of them turn out with a clean slate.
Eventually I found the culprit
Guess who , humans.
Actually we are the roots of these problems.
THIS IS WHAT WORLD LOOKS LIKE IN GENERAL.
THIS IS HOW WE SEE IT.
Somehow we have managed to destroy our planet and the manner in which we are heading is more dangerous than what we had done till today.
Now we have nuclear weapons, chemical weapons, ICBMs and whole lot of secret weapons.
If in case, any how World War III happens, not only we all will be dead eventually planet will be dead.
We humans are not even able to find life on any planet in the universe, and still we are preparing to destroy one, which already have.
And fact of the matter is that, we all know what I am taking about, and still waiting for something to go wrong.
I generally never ask but,
Don’t let it be just another article, I want you to share and aware about this.
Rest is up to you….
