Do you think that there are other worlds orbiting the stars?

A long time ago in a galaxy far far away...

I know that, I was just saying their not as small as we see them. I told you, I just started astronomy class, I know about the different types of stars.

But I think that all the UFO's and such are just lives on another planet that our WAY ahead in technology then we are.

Sorry. :) I couldn't resist the urge to do that.

To stay on topic I have to agree with Maxx Power. The only outer space lifeforms would probably be bacteria and single-cell organisms. Multi-celled organisms would probably live way too far from us for us to notice.

All of that is theory that noone can prove.

How do we know that the universe isn't round and that the farthest we can see with the most powerful telescope one way is only one foot from the farthest we can see in the opposite direction. We would never know. I'm sure someone is going to get cocky and say blah blah this says this, but they can't prove it anymore than I can prove what I just said.

But the galaxies are expanding? Maybe it's the things inside this round universe moving around, instead of staying in the same spot.

But the stars are millions of miles away? Prove it. Maybe they are really small and just burn hot enough that the light reaches this far.

Yeah, whatever.

Absolutely. If there isn't life on at least one other planet in the entire universe, I'll eat Neel's hat. With such an inconceivably massive area, it's just illogical to think that we're the only living creatures out there.

There could be more advanced aliens out there because our solar system has a middling yellow sun in the middle of the first part of its life, not yet at giant stage. Other stars are much older and could have had planets and life existing for longer so more advanced alien races could have arrived.

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.

Yeah, I agree.

Hmm, I thought our sun was one of the biggest? (Or at least one of the biggest known)

Not by a long shot.

Even if there is life on other planets (and there probably is), it's unlikely that we would be able to contact them. Let's face it, the universe is pretty damn big. Also, they most likely wouldn't be able to survive on earth, or earthlike conditions.

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.

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.

and the drake equation says that there are 7,000 earth liek planets in the universe.

Oh and I think about this stuff every waking moment I can. srsly

*plays star wars theme* Life may exist somewhere else but they aint been here, Theory of Relativity kinda proves it.

The theory of relativity misses one important factor. It puts a limit on one thing and assumes that limit is also static. That's like saying you can't create anything hotter than 10,000 degrees. There's no limit to heat, except for the lack there of. Just like light intensity. After a while it all blinds you the same. But the only limit is absolute darkness. Just like mass. Though after a certain point it's inconceivable to imagine, it's still possible. The only limit is absolute emptiness. Speed I would assume works the same way. The only limit is really standing completely still. I think it's possible to go faster than light. It just might be impossible for us to actually accomplish that. But then the laws of physics supposedly kinda break down so who knows how that would work. Then bring in worm holes ^_^ In a million years we could totally visit life on other planets.

But I agree. The bigger question is whether or not that life is sentient and technologically advanced enough to care about. Also its assumed most life has to meet the goldy-locks zone requirements. i.e. earth and human living conditions are "just right". It hard enough to find life at all. Let alone something else out there that's just right for their conditions. Also, we focus on finding carbon based life forms. We assume that other life has to develop under the same limitations that we did. And I'll skip all the technical jarble, but for the most part they're right as far as I know. I saw something on this, and the only other base they could think of was silicon I think. And that possibility would have merely created rigid crystaline plant-like things. Not something we could eventually communicate with.

But I totally think there's other life out there. And I really hope at least one other life form is sentient.

the reason you can't travel faster than the speed of light is because mass converts to energy at speeds that high.

The closest star to earth after the sun is a star called Proxima Centauri which is around 4.2 light years away, seeing a light year is how far light travels in a year (makes sense) that star is some way away. But there are others, when you look up at the stars in the sky, some are much much much further away. Some of them probably are not there anymore, they have died and what we see is how the star looked like light years ago. So i say there is life out there somewhere. It's just finding it in time.

Well, consider that our sun isn't due to stop doing it's sun thing for something like 4.5 billion years. I'm fairly confident that after that length of time, we will have figured out a way of taking care of ourselves in some other way. If intelligent life gets even a few million years, it will most likely be able to ensure a situation where it will survive.

A lot of people seem to have me confused:

Galaxy = The Milky Way = Where we are
Universe = Everything at all

I never said that the equation said there was no life in the UNIVERSE, I said it claims that there is no life in our GALAXY. There's a big difference. There's almost as many galaxies in the universe as their are stars in our own galaxy. So even if we are the only ones in our galaxy, then logic would dictate there's at least one sentient lifeform in each galaxy. Problem is the distance between the galaxies is so insurmountable that attempting to contact each other is out of the question.

And for the record, the first transmission capable of being picked up by aliens would be an address by Hitler. Fitting that one of histories greatest monsters would be the first signs of intelligent life seen on our planet. I'd imagine based on that we're the planet everyone avoids. :rolleyes2
