5/5 Are We Alone In The Universe?

For fifty years, the Search for Extra Terrestrial Intelligence has been scanning the galaxy for a message from an alien civilisation. So far to no avail, but a recent breakthrough suggests they may one day succeed.
Horizon joins the planet hunters who've discovered a new world called Gliese 581 c. It is the most Earth-like planet yet found around another star and may have habitats capable of supporting life. NASA too hopes to find fifty more Earth-like planets by the end of the decade, all of which dramatically increases the chance that alien life has begun elsewhere in the galaxy.

I wish I was smart enough to get into astronomy professionally.

I love space and everything about it. I only wish I had the determination to follow my dreams...

2 people think stars are fake and that the government put lightbulbs in the atmosphere to fool us.

100 years later...

John: Hey Bill, remember that old dead planet Earth?

Bill: Ya, I watched it collapse through my telescope last night.

John: Well i'm glade we where able to build a spacecraft to fly us to Gliese 581g.

Bill: I agree. (Thoughts) I think this is gonna turn out like that ancient movie, Avatar.

they realize that there are other elements that could combine to create life (silicon based for instance) however water is the only one we are sure of.

@lee155912000 it's never too late to realized your dream, no matter how old you are. Determination is all you need.

Is that Sigur Ros at around 3:50!?

@lee155912000 make it a long term objective then make an action plan first

As life evolves in any tempurature, the entity will obviously be able to sustain that tempurature. We even see this here on Earth with polar bears able to sustain extremely cold temps and in the water for extended periods of time, to cactus plants that need little water to survive in extremely hot climate. This would likely be the same in other planets as well. It shouldn't be any surprise to find life in temps of consistant +200 degres to -200 degrees if evolution has its time to do so.

@terra61 its not a necessity, its just far more likely to find a carbon-based life that thrives on water rather than anything else for two simple reasons: 1. Hydrogen, oxygen and carbon (excluding helium because its chemically inert) are the most abundant elements in the universe. 2. Carbon is the most chemically active element. So something like a silicon-based life wouldn't be as nearly complex as carbon. If life is out there elsewhere, it still is restricted by Physical and Chemical Laws.
