he iam thinkin that there will be a another planet lik earth in any other system lik solar..is this possible?

Question

becoz...there is a possible that the planet in any other system or milkyway is may have the similar proposition of chemical n the distance between their sun.....so it is possible of existing earth n the people may also live there.......tell me an god answer is that possible?not means give the reason?

Answer 1

Yes it is highly possible. Think about all the stars in our galaxy. There is roughly 2 to 4 billion stars total in the milky way. As for life it is as well highly possible. Life on other planets may not be alien life but it could be bacteria. Which is consitered life.

Answer 2

Dear Sarath:

It is 99.5 percent certain that there is not any life within our Solar System except on Earth. Earth is the only planet in our Solar System which seems to have all the right conditions. However,
our Solar System (the Sun, 9 planets, and their associated moons) is only one of many, many, many solar systems in the universe. Remember, our Sun is actually a star.

Look up into the night sky on a clear night. Almost all of the stars that you can see with the naked eye are part of the Milky Way Galaxy. Each of those stars is the equivalent of our Sun, and there are 100,000 Billion of them out there. Our Galaxy (capital "G") is shaped like a disk, 100,000 Light Years in diameter, and 1000 Light Years thick. The center is a dense mass of stars that is very bright, and spiral arms extend outward from the center. Each spiral arm contains just millions and millions of stars. Each star could have from 0 to 10 (or more)
planets with their associated moons circling around it in various orbits. We are not normally able to see those planets because of the immense distances involved and the brilliance of each of the specific stars which blinds us preventing occasional glimpses of them.

Our Milky Way Galaxy is only one of thousands of other galaxies out there. Each of those galaxies contain billions more stars, and planets, and their associated moons.

Given that immense number of stars, the chances of there being one or more planets which are the equivalent of Earth are pretty good. It is not possible to tell you when or how we might detect the existance of other Earth equivalents. However, you can believe that it will be far, far away from the Earth. The nearest star (other than our Sun) is, for example, 4.4 light years from our Sun. So if some kind of discovery were made around that star, radio messages would take 4.4 years to travel there, and 4.4 years for an answer to come back if they had radio communications technology similar to, or compatible with ours.
4.4 + 4.4 = 8.8 Years per round trip radio message.

As a result, the start up time before serious dialog might commence appears to be 50 years or more (estimate 4 to 5
initial attempts). Now, what language do you suppose they
might speak? Who knows? Math is a common ground and
may comprise most of the text all early communications attempts.

Answer 3

What was found until now are gas giants circling very close to the star. I thing that around such stars a planet similar to earth is less likely, but I'm not certain about that.
otherwise there is no reason why most stars would not have planetary systems with many planets, some of which could have similar conditions as earth has. after all, the only star we inspected rather well has 9 planets.

Answer 4

The number of stars in the universe is currently estimated to be about 1 x 10^23. The number of planets is estimated to be 1 x 10^13. As far as we know, all planets are made of the same material. elements from the periodic table. So it's entirely possible that there is indeed another planet that has the same temperature range as the planet earth. it's also possible that said planet contains water.

As to whether or not people live there. Don't get your hopes up.

Think of us like this. Energy, maybe in the form of tiny strings grouped together to form tiny particles. such as quarks and electrons. Two up quarks got together with a down quark to form a proton. Two downs quarks got together with an up quark to form a neutron. 1 proton + 1 electron made hydrogen. 6 protons + 6 neutrons + 6 electrons formed carbon. 8 protons + 8 neutrons + 8 electrons formed oxygen. 7 p + 7 n + 7 e formed nitrogen.

5 carbons + 6 hydrogens + 2 hydrogens + 2 oxygens came together and magically formed thymine. similarly adenine, guanine, and cytosine were formed. along with deoxyribose.

somehow. about 3 million of those molecules came together to form a singe strand of DNA. Two DNA's for a double helix. That forms a single chromosome. you have 23 in one of your infinite number of cells in your body.

within the DNA are sequences of these molecules that produce proteins. via RNA and messengar RNA etc. they are called genes.

Somehow all of that infinite chaos works together to form you.

The odds of people just like you developing on another planet are so small that I'll go out on a limb here and say it's impossible.

Not to mention this.

1) you're 10 light years away from the next nearest planet beyond our solar system. traveling at the speed of rocket (1/10 the speed of light), it would take you about 200 years round trip. You won't live to tell us all about it. keep in mind too that from the earth to the edge of the known universe is about 50 billion light years in any direction. you won't get far....

2) our definition of life is limited. based on life here on earth. reproduces, eats, grows, reacts to stimuli, etc. There is no reason to suspect that life other than on earth will fit that description.

3) we operate on a timescale of seconds, minutes, hours, days, etc here on earth. Other life, if it existed, may operate on a picosecond or millenia basis. we would not recognize it's movements.

In short, the odds of another planet resembling earth are fair. The odds of other people existing out there are zero. the odds of other life that fits our definition of life is extremely poor, the odds of us reaching said life is very very small. It certainly won't happen in your lifetime...

Unless of course you believe in creationism instead of evolution. In which case let's say God created the universe and man (perhaps through evolution) and he did it over and over again. Still though, there's the distance problem...

Answer 5

Yes it is very possible and likely is a fact.
Though we may never have any direct evidence o f other intelligent species,like us, you can be sure there are millions of them throughout the universe.
They would probably be based on some type of DNA so it would be futile to try and describe their looks.
Imagine trying to describe what any animal on earth may look like without ever seeing one!

Answer 6

It's very possible considering the number of stars just in our galaxy.... Check below for a way one astronomer estimated the chances. It's called the Drake Equation ...

Answer 7

Astrobiology tells us that the Earth/Moon combination we have is very uncommon, as is our highly metalliferous sun. Combine that with our nearly circular optimum "Goldilocks" orbit (not too hot, not too cold), and most will agree that it is extremely unlikely to be duplicated exactly in this galaxy, not to mention the various mass extinctions of many species, like that of the dinosaurs, more than 62,000,000 years ago, without which mammals like us would still be hurrying out of their way.

Answer 8

It is possible as we donot know about it if we send a message to them it would take the message more than 20light yrs to reach and more 20light yrs to come back.So,you may be right or wrong.

Answer 10

yes it is possible, i think of it many times too
