Definitely not, but there's a bigger chance we're the only planet with THIS kind of life. The way aliens always look like mutated humans in movies is silly.
[QUOTE=AceOfDivine;33314565]Space has more stars than we have people.[/QUOTE]
I find this sentence a little misleading.
There are 7 thousand million (7,000,000,000) people on earth.
The Milky Way a galaxy, and has 100-300,000,000,000 stars, of which all have a random amount of planets.
In '99 Hubble estimated that there are 125 billion galaxies in the universe. When they put a better camera on it, hubble detected twice as many galaxies so the estimate is growing all the time.
So let me correct your sencence.

For there not to be any sort of life anywhere sure would be a waste of space.
[QUOTE=Rad McCool;33297675][U]What numbers?[/U] The size of the universe is not alone an argument! Look, think of it like this: You have 100 boxes. Inside each box there can either be a green ball (life) or a red ball. You have opened one box so far, and there was a green ball in it. How can you from only this information estimate the remaining number of green balls? The answer is you can't! But can't you at least make a qualified guess and say that there is more than one green ball out of all the 100 boxes? No, you can't. You don't know the green/red ball ratio. You don't know how likely you are to find any color. If the ratio happen to be 1:100 or less then you would [I]not[/I] be more likely to find any green balls. And the other way around. And even if you add like a trillion more boxes with the same conditions then it's still impossible to know, since the ratio can move equally many steps in [I]each[/I] direction. Don't say it's more likely or not unless you show your calculations for those chances. Of course I understand what you mean. I too believe there is much life out there. But I [B]believe[/B] that. I don't present it as science and force it upon anyone by using made up probabilities and statistics that don't exist. PS. Sorry if I'm coming off harsh. I just feel like I've explained this a million times without any success.[/QUOTE] You probably have and the reason it's full of fail is that it relies on absolutes, which the universe pretty much ignores except for the most basic of laws.
[QUOTE=Intoxicated Spy;33299297]Mathematically, its is impossible for there not to be, in the 100 Billion Galaxies, which most have 10 Billion Stars, and maybe of those stars, 50% have planets.[/QUOTE]
No it's not. We don't know whether the conditions ideal for life are common or not.

[QUOTE=Triarii;33311720]True, I see where you are going but there is a difference between fiction and a theory. The unicorn was made up by people and is obviously not real (i.e.fictional) but a theory is an idea that is yet to be proven.[/QUOTE]
Not quite true, a theory is a body of information to explain a known phenomena, there can be multiple theories for the same phenomena.
-snip-
I believe there is, so much damn room in space. How could we be the only ones?
[QUOTE=Thoughtless;33319953]No it's not. We don't know whether the conditions ideal for life are common or not.[/QUOTE]
But is that the question?
Really, think about it. We have spacecraft. What if conditions were ideal in lots of places but they no longer are so welcoming?
One day, humans will be migratory, so imagine if something out there is migratory already, or is looking into it, or is right at our stage, or earlier. We could even go as close as the moon, or Mars. But we could go further than that; we have found places that hypothetically could sustain life rather far away, and I can't tell you whether or not we could reach them in a lifetime with current technology. But think about technology that could come in the future. The possibilities are endless; what if something else out there has already developed something we cannot even begin to imagine? We're sending radio signals out into space and I believe our best bet has fifty years yet to reach its target, and longer of course for any response at all to make it back. What if there is a response?
Do you really believe that we here on Earth are the leading stick of intelligence?
Almost certainly other life out there, we however are unlikely to ever find any of it, and even if we did chances are it will be very basic life. Thinking about the sheer time scale and the tiny little pinprick that is our pitiful existence as a race the chances of not only finding anything within our reach, but also existing in the same timespan as us is so incredibly tiny.
Even if there are billions of other planets out there with life, the number of them with life that made it off their particular rock before their sun died or an asteroid or some other disaster wiped the planet and then somehow survived billions of years as a race. Just so the time period they occupy in this universe overlaps with another intelligent space faring race. As I said, chances are dismally tiny.

I think you meant to say 7 thousand million, 7 billion. Also although there are countless numbers of planets around stars not all stars have planets.
[QUOTE=Triarii;33325442]I think you meant to say 7 thousand million, 7 billion. Also although there are countless numbers of planets around stars not all stars have planets.[/QUOTE]
Yeah I meant. It's a little confusing when billion = 10^12 in old british english, 10^9 in american english, and 10^12 in finnish. it's the americans trolling the world again, because -illion originally refers to million and bi- refers to second exponentiation. Million^2 = 10^12
The same goes with trillion. Tri means three. Million^3 = 10^18. But those fuckers call that 10^12
Yeah but most have. And like with the previous hubble estimate, the estimated number of planets is growing every year because we're detecting smaller and darker planets.
I was wondering that if you had a Sun ten times bigger than our Sun. Then you have Earth, Pluto and the rest of them planets also ten times bigger.
So in theory, our solar system being being ten times bigger. So the distances between each planet wouldn't change, only more massive solar system, you know scaling up.. Then there would be people ten times the size of us!
My mind wanders..

Possibly, or we would have evolved completely differently to cope with the different mass

Well then the gravity would pull everything together. The planets's tangent velocity would have to be much much bigger not to be swallowed by the sun.
To be totally honest I wouldn't be surprised if there was even life outside of Earth in our galaxy.
I'm pretty sure there is. But I don't think they would try to invade our planet for they probably are in the same position as we are. Thinking that they are alone in a massive universe.
