I'm just asking, I'm studying to be an astronomer and when you think about it, if each star is as big as our sun, then there are planets orbiting them. Could there be life on those planets? If so, what do you think they are like?
Do you think that there are other worlds orbiting the stars?

More than likely. The universe is pretty big (from what they tell us.), so it'd be pretty boring if we're the only life here.
I guess that would be possible, but then it could be like Independence Day
all over again. Were going to have to rely on Will Smith to save our butt's.

We're doomed.Originally Posted by Luther X-Rated
Given the size of the universe and the sheer number of galaxies/stars/planets, I say that it's highly probable there are other inhabited planets out there somewhere.
Isn't there some law that says every event can be perfectly reinacted at least once? So that would mean there could be another planet exactly like ours.
I doubt a planet needs to be exactly like ours to support life, though. If there is other life out there, which I think there probably is, I doubt it'd be anything like life on this planet.
70,000,000,000,000,000,000,000 stars currently thought to exist in our universe.
You try and tell me that we're the only ones. Just try it.
But not all stars are the same size as our sun. Very few are. Still, most stars have a reasonable orbital area which is judged to have the right conditions for life. (Though some would say this is a prime example of carbon chauvinism.)
The real questions arise in the following forms;
How many races are within a distance we can reasonably make contact with?
How many races are within a distance we can reasonably travel to? (Largely this depends on whether or not there is a maximum speed limit, and whether or not we can circumvent it.)
How many races are within a recognizable span of evolution, both scientific and cultural? (Sure, we could probably work with a species with the equivalent of 10,000 BC quite easily, but 1,000,000 BC? Similarly, the future might offer even smaller scope - just a few thousand years could grant so much technology as to change a race beyond recognition. On a cosmic scale, it's unlikely we'll find many races close to our own, in this regard.)
How many races survive until the age of radio broadcasts, and how many of those until the space age, and how many of those survive until they establish self-sustaining colonies on other worlds? (Which I consider the point when a race has guaranteed survivability. A natural disaster of anything smaller than a star dying wouldn't take them out.)
But they are out there, I will stake anything on that. The chances of aliens not existing is so ridiculously remote as to make the question an exercise not in probability, but in comedy.
I have to agree with MILF on this one.
Each star is as big as our sun? Try way, way bigger. Stars can range from tiny to whopping big. Our sun is one of the smallest known stars if I remember rightly.
Hmm, I thought our sun was one of the biggest? (Or at least one of the biggest known)
Our sun is in the middle of the temperature range and is one of the smallest stars in the middle of its life (dwarf stars are at the end of their life). A bigger star would just have the area where liquid water is further out.

There are almost undoubtedly other lifeforms out there in the universe somewhere, for the reasons Mr. MILF has already stated. That said, the chances of them actually contacting us are pretty remote too, so I doubt we'll be partying with the greys any time soon.

Actually, mathematically speaking, it's not unreasonable to assume that there are no other forms of sentient life in the galaxy, though there are most certainly other forms of life out there. We know of bacteria once exsisting on Mars from fossils found there, and it's theorised that comet's ice may contain bacteria also. However, in terms of multi-cellular life, the probabilities are extremely low. I can't remember the name of the theory, but I believe the technical number of planets that can support life in our universe is 10^-31 (that's 0.0...etc. with about thirty zeroes added on). That is a VERY low number indeed, well below zero infact.
So yeah, despite there being so many planets, chances are we are quite literally alone. Other galaxies possibly, but certainly no "next-door neighbours"
There is no signature here. Move along.
If you're talking about the Drake Equation, most of the values used to determine the total are based on assumptions rather than any hard evidence, since anything on the scale of the universe is nearly impossible to quantify to a reasonable degree of accuracy. To trust that such a system would give a reasonable projection of the number of sentient lifeforms in the universe would be foolish.

Well, (I start almost every post with well,) I heard one time that if Aliens could somehow see this planet or something, from wherever they are, we would still apear as we were many, many years ago. Something about how light travels through space. So technically we'd still seem like very primitive beings to them, and probably wouldn't interest them.
