howcome its possible?

Question

howcome its possible that the earth is so small in the whole universe and dust, meteors or any distructive object and doesn't fall on earth and completely or partially damage the surface? and incase there is something really gonna happen in the future, are we prepared for it??? if yes, what???

Answer 1

They burn up in the atmosphere. Meteors are brilliant flashes in the night sky. They travel 60,000 km per hr. At those speeds friction with air particles vaporizes an average size meteor in less that a second. The flash of light is caused by the intense heat of vaporization. Only on rare occasions a chunk large enough to survive the plunge hits the ground. This is called a meteorite. The largest meteorites surviving the plunge do damage the surface of the earth and cause craters but this rarely ever happens. You probably wont ever see it in your lifetime.

Answer 2

Stuff is hitting the Earth everyday. Most of it burns up in the atmosphere but just about every day something does hit the surface...though it may be the size of a pea once it finally does.

Large things have hit the surface in the past and there are many impact craters on the Earth to prove it, such as Barring Crater in Arizona, the Manicougan crater in Canada, the huge Kebira crater in Libya, and hundreds more. You can see many of them here:

Once in a while something large doesn't make it to the surface but explodes low enough the atmosphere to be a danger.

This was the case with the Tunguska event when what's thought to have been a comet entered the atmosphere and exploded over a remote area of Siberia. The explosion was so large that many around the world noticed it. The event left no crater as the object didn't actually hit the ground but destroyed the forest for miles around.

Answer 3

Most meteors or shooting stars that we see falling have the size of a grain of sand. The bright fire balls are the size of grape. These objects burn up miles away, as they enter the earths atmosphere. Larger objects sometimes reach the surface of the earth. These objects are known as meteorites. Hundreds of meteorites reach the surface of earth each year. India had 10 meteorites falling on its main lands in the past few years. However, none have been know to cause damage. However, several meteorite impacts have caused damages in other countries like the Park Forest meteorite damaged several houses, broke window panes, a few cars etc. The Porter County meteorite broke the rear window of another car. There are many such stories world wide.

But there are time when larger ones do fall causing destruction on impact. A well known case in India that fell around 50 thousand years ago in Lonar, in Maharashtra state. Another known impact site is Ramgarh, near Kota in Rajasthan. The arizona meteor crater is the most famous one in the world.

Several international and national agencies are constantly studing for potential and harzardous asteroids better known as Near Earth Objects. A lot of amateurs are also doing the same in helping these agencies search for such asteroids.

Answer 4

Stuff falls on us every day. Usually, no one notices - it's small stuff. About every 60,000 years on average, something big hits us and makes a decent-sized crater, like meteor crator in Arizona. Nothing that big has hit us in about 60,000 years, but a small asteriod hit Tunguska, Russia, about a hundred years ago and made the news. The Moon is also pretty good about deflecting stuff and getting hit itself instead of us.

We are looking for stuff that might hit us everyday (space watch telescopes) but we don't really have a plan for what to do as far as I know.

Answer 5

first the earth isnt that small ,it has a large mass so much so that it is able to sustain an electrical charge ,that greates the things we see as gravity ,that gravity holds the air and ethers , to itself the ethers support a charge that creates the other protections ,ion ophere etc ,that deflect much and causes any thing to enter its protective boundry ,to get friction that creates heat that burns up most of the stuff likely to came
much has come in the past ,there have been massive extinctions in our past
things may or may not occur in our future but chances are from our histry that this too will pass ,we are as prepared for whatever happens as we have ever been ,we have science and teqnology ,we are the clever animal our only real threat is other humans ,it is our fears that can really hurt us not gods creation.
chances are nothing bad will happen ,but its a matter of faith ,we trust god made us smart enough to survive anything ,and worst gets to worse we go to heaven or hell depending on what good or bad we did in our lives,
anything likly to hurt us we would know , worry wont make it happen nor stop it from happening ,but worry sure wont help,
have faith in the one who created this amasing earth knew what to build in to it to keep it going.

Answer 6

Considering the vastness of the space it is only a remote chance.Though we can't say we are well prepared to stop such happening I thing we are capable of knowing beforehand and try to deviate such objects from hitting earth through some missiles..

Answer 7

in this universe we are living by luck. it some thing gonna hit this earth if we can manage to escape from its OK. but larger than expectation and larger than imagination we may not escape. till now no such thing happened and it is not going to happen because a heavenly body which could damage/change the shape of earth cant come of its axis by gravity which it is influenced or it has got. probably it may not happen.

Answer 8

The only thing that saves us is that space is so vast. We are not prepared for any significant impact from outer space.

Answer 9

ok first of all, the urge to have sex is organic and it runs in all individuals. no matter if you pick to ignore it for non secular applications it really is high-quality, because its your determination. everybody is diverse yet a non-non secular human being like myself can love someone purely an similar as a non secular human being, and by no potential purely favor them for sex. i might want to love someone an similar if she replaced into my lady friend or if she replaced into my spouse, it makes no enormous difference. yet sure i do have sexual urges and favor to exhibit them. i might want to definately favor if that human being replaced into in a courting with me although. SO, faith doesnt play as enormous of a area as you imagine. anybody can love someone no count number their perspectives.

Answer 10

no we aren't prepared for it. it's an unknown like hurricanes and fires, and floods, and tornados, and the entire cosmos.
