Any truth to this?

The planets, stars and the "space" b/t us and them are very real. It boggles the mind just how much distance there is b/t it all.

IMO, it's just logical that we can't be alone in this much space. Sure it's possible, but I don't think it's probable.

I wouldn't even say its possible. Depending on what you meant by "alone". I guarentee that there is other life out there, its even possible we will find life on Saturn's Ice Moon (forget which one it is). It just won't be sentient life. Now it is possible that there is no other sentient life in the universe, but even saying that is a huge stretch if you ask me. As for life as a whole, its not even possible that with all the space there isn't any other living organisms out there

Why do you think that humans on earth are the only smart life out there? I don't have any proof that there IS other sentient beings, but with all this SPACE and us knowing comparitively nothing about the universe...we can't be the only ones with brains out there.

You also have to remember that intelligent life probably only exists for an instant on a long time scale. We've only been "intelligent" for a few thousand years. We've only been able to transmit electromagnetic signals for less than 100 years. We've had the ability to wipe out all intelligent life on the planet for about half a century, and we've come very close to wiping ourselves out several times in this short time span. Considering these factors, isn't it almost inevitable that most "intelligent" species on our scale would wipe themselves out before they could be detected or detect others?

I don't remember who, but some sci-fi author had an idea for a self-replicating robotic satellite that would spread throughout space. Logically, if an intelligent lifeform were out there that could produce such a "race" of robots existed, then we would have seen something resembling these constructs. There are countless other ways for a civilization to make itself "known" to the rest of the universe.

I think it's inevitable that there may have been intelligent life on other plants and that there will be intelligent life on other planets. Is there intelligent life out there right now is the important question, to which the only acceptable answer is "maybe."

Because it will have run out of Hydrogen to burn, and will start to burn its Helium. Think of Stars as sustained explosions, held back by gravity. The more powerful the explosion, the more the star will be able to overcome its own gravity. When it starts its Helium phase burn the star expands because it is exploding with more violence and is less stable.

Interesting... why doesn't it burn the helium now?

It is in an indirect way by converting hydrogen to helium

It is the nuclear reaction of converting hydrogen to helium that produces the energy. However, over time the hydrogen runs out. Dense heavy stars quicker and light weight stars slower.

Man, after looking into all this stuff more and more it just makes me feel so insinificant in the grand scheme of things!

Makes me feel like WTF's the point of working day in and day out just to pay bills when theres soooo much out there in the world alone and even that is just a spec of sand in the grand scheme of things.

Makes me just tempted to sell all my belongings, drop whatever I'm doing in life and go explore and see the world, and mostly try and understand whats out there.

It surprises me how many people didn't have a relative idea of just how big things are in space.

Here's some more trivia.

The nearest star from us besides our sun would take over 40 years to get to traveling at the speed of light. (40 lightyears away) That's right, 1 star, your entire lifetime, traveling at a speed we cannot travel at.

It currently takes us 3-4 years just to get to Mars at our fastest speed... imagine traveling to that star at that speed. We are probably talking thousands of years then.

I was just wondering, are there any known planets orbiting the nearest star? I've never heard anything about it.

Oh, and about the blackholes that was brought up earlier.. I believe some tv show(discovery channel probably) said that their is a black hole at the center of every galaxy. Thats why the galaxies exist in the first place, the gravity is drawing all the stars into them. If there weren't black holes wouldn't it be reasonable to asume that all the stars would be distributed evenly throughout the universe instead of being in dense groups of galaxies?

Here's a nice link with some pictures.

A nice picture of our galaxy, showing where our sun is at.
