(adsbygoogle = window.adsbygoogle || []).push({}); Hey NGU,

I was outside of my house one night and then I just gazed up at the stars that which I havent done for a while. i was thinking. Are we alone? no I dont mean ALIENS, but maybe another sun with planets. Then on one of those planets that there would be some kind of living organisms like us with NGU websites and maybe Call of Duty 7-Future Warfare lol

The Universe seems so big for us to be the only living organisms if you acually think about it. Well yeah, this is just my piont of view.

Whats yours?

:cool:--Locs

It's possible, you may never know.

It is very possible, but you also have to think about the size and heat of the star. One can't say, "There are so many planets in the universe that there has to be life." "Why?" "It just has to be." "Prove it." "No, u." So, here is my essay on the topic explaining why I believe that there is life, but we will never make contact with it.

You also have to take into consideration the size of the planet and the proper amounts of gases required to support life. Think about the rotation of the planet on it's axis and around it's sun. Judging by observations on our solar system, life cannot be supported on other planets due to many reasons. I will list a few, such as: temperature, gas composition, and bearable climate.

So judging by that statement, we can determine that Earth is the only planet we know of that has proper necessities for life

The only way a planet can support life is if it's sun is in the proper life-stage of a star. So if a sun is near the end of it's life, it will be very cool and a planet would need to be much closer to it (such as the distance of Mercury to the Sun). If a planet is too close to that sun, then odds are that it will experience much more intense radiation and have undesirable amounts of gas. If a star is hotter than our Sun, then a planet will need to be farther away from it in order to be cool enough to support life. I am not positive, but I believe that closer a planet is to a star the smaller it is, so if a planet is too far, then the planet may be too big to support life. If a star is too massive, then it's gravitational pull could (I am saying it could happen, not that it will happen) cause planets to be too small and thus not allow intelligent life.

From what I have read, most planets we see are very large in comparison to Earth. This means that the atmosphere will be farther away from the body of the planet (thinner air). The planet will probably be further away from it's sun than the Earth is to it's sun, which means it will need a hotter star to revolve around.

The Hubble telescope can pick up about 80 billion galaxies currently. On average there are about 100-200 billion stars. Meaning that ~33-66 billion stars have planets orbiting them (per galaxy). The odds of everything being in place to create intelligent life is about...drum roll please....

After some math I came up with this number: 0.000000000103%

Simply trying to make things easy to think about.. If every star, in the universe (as we see it), has 10 planets around it. Then we can conclude that there are ~495000000000 planets, meaning that about 51 planets could support life, per galaxy! Meaning that 4080000000000 planets could support life (judging by size) So I think it is very possible.

After some math I came up with 0.00000768% that a sun has the proper heat, size and the planet is the proper distance from it to support life. Also using the idea that there are ~49.5 stars, with planets orbiting them, we can conclude that 380160 stars are similar enough to our sun and that they have a planet orbit similar to the Earth's, per galaxy.

I feel like we will never leave our Solar System, so we will never get to see if there is life outside of it. Odds are that it is there thou, it just isn't likely anything is going to leave it's galaxy to come to ours, because in order to reach our galaxy, it would need to travel faster than 1/3 the speed of light!

The only chance we have of reaching other intelligent life is if it from a different solar system, in our own galaxy. Our galaxy is so huge, that it could take more than a lifetime of space travel to reach our nearest star! The nearest star is Proxima Centauri, and it is 24920647758761.1 miles away. The fastest we can possibly travel right now (with a modern space shuttle) is ~4 miles per second. Going this fast, it would still take about 162561.3 years to reach that star!

Odds are that I am completely off, but take what I say and criticize it, as I am sure I am totally wrong on some things.

This whole essay/post explains my view, that if God created other life, he definitely did not intend for us to make contact with it.

you're asserting that life would have to be similar to what it is like on earth with those listed conditions though. imagine a silicon based life form without DNA that thrives in cold acidic gas giant clouds.



actually, an earth-like planet was recently discovered which shares many of the same characteristics, and may even have liquid water.



not necessarily. towards the end of the sun's life (the red giant phase) there will most likely still be some form of life on earth before the planet is engulfed. or maybe a roaming planet gets caught up in a newly born star's gravitiational field. or possibly even a planet's organisms thriving off the gamma radiation of a neutron star.



Actually, toward the end of a stars life it gets hotter (because it starts fusing helium atoms into beryllium once the hydrogen is used up). The phase is called the red giant phase, and the star will expand, engulfing the inner planets. A planet closer to the star would be vaporized.



yes, but that's only if the alien life is anything like earth's.



nope. mars is smaller than earth, saturn is smaller than jupiter. the star will tend to steal matter from very close planets though (for example how the sun pulls off any gas from mercury, which is why it has no atmosphere whatsoever.) its pretty much a matter of what matter forms where. rocky debris are more dense, and their iron, aluminum, nickel, etc. makeup brings them closer to the sun when the planets are forming.



why would the size of the planet effect it's ability to yield life?



chances are that if the star is large, then the amount of matter orbiting the star when it formed was relatively large as well - meaning that the planet would probably have a better chance of being large than small.



yes, most planets are gas giants. their atmospheres are actually much thicker however, do to nearly the entire planet being made of gas.



not necessarily. Jupiter's moon Europa most likely has liquid water beneath it's ice surface, and it has the possibility of harboring life. Hydrothermal vents may provide energy, much like some of earth's organisms take their energy from the earth's hydrothermal vents.



how'd you come up with that number?



only about 5% of stars are estimated to have one or more planets planet.



how'd you come up with that? also, that's asserting again that life elsewhere would need to be like and necessitate earth-like life.



i'm confused... i'm not really sure what you meant by that one.



well we sent four probes that are already out of the solar system (voyager I, voyager II, pioneer 10, and pioneer 11).



there is no speed something would NEED to be going in order to go to another galaxy. anything could get here eventually going one speed or another - some just take longer than others. 1/3 the speed of light isn't particularly fast either. an antimatter orion project pulse unit is estimated to be able to reach between 50-80% the speed of light.



actually, intergalactic travel has been proposed by in essence "cheating" the speed of light. wormholes, warp drive, and hyperspace would be effective ways to easily outpace the speed of light.



traveling in an orion antimatter unit, it could take theoretically only 5 years to get there. in a hyperspace craft, it could theoretically be as fast as we want it.



glad i could be of service .

I think there are aliens no doubt. Since space is endless, there are probably many, many universes somewhat simaler to ours so I wouldnt be surprised if there were some forms of dinosaurs living on those plants. Saying theres an NGU and COD7 is a stretch though..

well if you're talking infinite parallel universes (which is actually the prediction of the best rounded "theory of everything" - M Theory) then theoretiaclly there IS a universe with another NGU and CoD7. In fact, there is a universe that is exactly the same as this one, except you aren't in it. There's on where the proton is unstable, and matter as we know it isn't formed. etc., etc.

It hurts my brain..

I guess it could be theoretically possible but seems improbable.

Well I believe many things because of my religion.. So I can't really say much except,I do believe there is stuff out there..

Elf I love you (in a weird love-hate way). There are some holes, because I worked on that post for about 2 hours and I was half asleep by the time I finally finished it. I also read online that Scientists are proposing the idea that 33% of stars have planets orbiting them, as opposed to 5%. I believe that intelligent life cannot survive, unless it is in a world like our own. I can't prove that, thou.

I believe there is another planet/s that support life. But what I don't understand is how scientists say that "this planet can't support life". Like why? Coltz said " life cannot be supported on other planets due to many reasons. I will list a few, such as: temperature, gas composition, and bearable climate." which is also what scientists say, but here is what I say. Someone who lives in a warm country/city/state travels to the Arctic area where it is like -60 degree Fahrenheit. They will find it extremely cold due to them living in a warm place, but to the people who live there they are comfortable with it. Then, the Inuit travels to a hot place where it is like +90 and finds it too hot, but again, the locals are used to the heat. What I am saying here is that both of these two people have 'evolved' into the climate over the time the earth has been around. My point being is that both those people have adapted to the climate, so why couldn't they on say Mars for example. Also along with this ling topic, I'm going to take you back 15 billion years. The first organism/bacteria lands on Mars. That organism evolves into a fish or whatever, which then evolves into a crocodile, to dinosaur to monkey or whatever you want them to evolve into. Then it makes us, humans on Mars. We breath in Carbon Dioxide. Scientists say that no other planet, including Earth can support life due to this and that exactly like now. However, from that single organism, it adapted and evolved for the next 'creature' to breath and live on Carbon Dioxide, just like it has here.
So to finish my rant, we now, over 14 billion years have been evolved and made to breath and live off the Earth's gases, meaning another planet can also do the same.




well, considering we don't have a CoD 7 then neither do they :p
