Another "Earth" Beyond Ours?

So,scientifically speaking our Universe is a massive never ending black space which has a few pockets occupied by galaxies and galaxies are made of stars and solar system. The reason life exists here on earth is because it is at a perfect distance from the sun that helped lighter elements combine and form heavier molecules, like water. If we were a bit nearer, most of the water would have evaporated and if we were a bit farther off, it would have frozen. So technically speaking any planet which is at such a distance from its star that lighter elements can combine to form heavier elements and these heavier elements in turn combine to give essential molecules, life can exist on that place. I do believe that more than a few handfuls of the trillions of stars that exist, should have that temperature range on one of their planets. Finding them, however is another thing altogether, and without any concrete proof of their existence or non existence all we can do is speculate.

Yes I believe there are more planets with living organisms who are very similar to us. We know there are more planets out in the galaxy and there are probably more than the one we know of. I think these living beings are more than likely wondering about us too.

I also believe that there is some form of life out there as well. The universe is actually infinite as in it has no ends. The chances of us being the only planet with only signs of life on it are so small it's probably like winning the lottery. There is a lot of proof out there that shows that there is life out there but there are also a lot of cover ups and arguments that can prove that there isn't. I think that this is definitely something interesting to think about because there are so many possibilities. Nice Fallout picture by the way. :)

I believe there is life on other planets, we know every creature has different way of life. To see if we're talking about is true then we must seek and find something. We certainly do not know that why the creatures living increasingly smaller. I think that's the revolution that led us to think, it might have been useful to this world is not full. Thus, living things that we never saw the possibility of being on the planet other than Earth to reduce the population density.

It can be possible that there is life form on other planets in far off galaxies. I don't think that they would be the same as Earth. I am not saying its impossible. I am just saying its very unlikely that there would be a twin planet of Earth.

The materials that make up our star and planets are the same as any other place. To get the proper distance between the star we just take time for the planet to drift into proper distance orbit. So if there isn't another earth it is a matter of time until something similar happens. I think that if there is life just like ours that they can calculate the size of star need, size of planet, and distance. They could easily use technology to locate us. but getting here would be a very different story.

It's statisticly certain that there are other planets out there that are similar to earth and could support human life. However, it's not necessary for us to find such a habitable planet in order to live in another solar system. It's quite possible to build space habitats, (and some have already been designed) that will allow humans to live anywhere in the universe. We just need a practical way of getting out there, that's all.

Well, just to get things stright, sure considering the universe we live in is endless, there is a slim chance that it could mirror Earth someplace else, however I will discard such option, because life, as well as evolution of planets and things is quite unique and the smallest ingredient missing or added up changes the entire equation. We may find a similar planet, that can support our requirements to live, but a mirror planet? Another Earth as we know it? I dub it.

I too believe that in this vast planetary system, there would be at least 1 earth-like planet, and may be even more. The life forms there may be the same gae as ours, more primitive or even more advanced. This, we cannot say. Let us wait for the day when we have communication with these people.

I believe in an "alternate" universe type of theory. For a long time I've considered a lot of ideas that were brought up in Star Trek's Next Generation. A lot of the concepts that rose up in that series were quite believable. I'm not a trekkie myself but I'd love to sit through this type of marathon anytime.

Well I've been thinking quite often about that. My thoughts have led me to conclusion, that there must be somewhere "another Earth". It's not very possible that the whole universe is empty, there are millions of stars and thousands of planets (although very far). One or more of these planets just have to be inhabited. The biggest question for me is how advanced these distant civilizations are? If on one day we'll manage to land our spacecraft on the surface of their planet, will we find a high-tech society out there or perhaps creatures from the deep stone age? We may never know.

it can not be possible to exist only our planet with life. i believe that there are thousands of other planets with diferent cultures. the universe is unlimited.

man u have stopped your imagination to short.i think about all the time that there may be some other universe in here where people would be similarly thinking about this.another earth we can definitely get one day but think about another universe.wat say guys?

I believe in it too. I always felt that the universe is so vast that there has to be life on another planet or galaxy. I do agree with you that they could be light years away from us as you rightly mentioned.

I think there are a lot of planets like earth in the universe. I would hate to think that we are the only planet that supports life otherwise what a waste of a universe you know. I do beleave that other life exist outside this planet and hopefully someday we will know for sure if it does.

Ah, this is an interesting one, I love this subject! I love watching those factual space programs 'Univers' being the one I watch the most. I love the information they are coming out with. I personally believe that there has to be other life out there, I don't believe that we are the only ones. The Universe is so vast with billions and billions of galaxies and billions and billions of stars that that is seems virtually impossible that there isn't something else out there. The closest planet that resembles our own is obviously Mars! If we were ever to colonise another planet then it would be the planet Mars! I think when I was watching the program 'Universe' it mentioned that it would take at least a million or billion years to leave our galazy completely and reach the next galaxy in line Andromeda! We can never reach or travel to these places without some superior technology. If there is an advanced alien race then it's likely that they may have mastered some kind of futuristic technology, something that would travel thousands or millions of times faster than light! This is a very indepth subject but I am just so fascinated by it all. Andrew

Hello, Yea I also think that their is another 'earth' beyond our galaxy that we can't even or will never ever see because it is too far away. So yes, I do believe that there is some form of life beyond our galaxy. Make sure you have a good day, God bless and Happy Lotting!!

I don't believe in another earth unless there is an official confirmation or some kind of proof. But it's really interesting to imagine about such a situation & also about the life & people in those planets. Even from childhood, many at-times, I used to imagine such things Happy Lotting

Like someone else said, I doubt if it would be exactly the same. Although as a big Doctor Who fan, I kind of like the idea of parallell universes, differenttimelines and all that! Who knows, Sci fi might not be all that far off - maybe we write and talk about these things because in some way we know it really. Or maybe its just the human longing for something beyond themselves, something 'more than this'.

I believe that anything is possible, really. considering how big the universe is, it's hard to tell that there are other living creatures aside from us. It would be really cool if we could find them and communicate with them. The possibilities are endless. I would love to meet an alternate version of myself. But for now, I think we should focus on the problems we have on Earth and fixing them, before we go searching for new ones.
