So we may have a candidate for life around one of Saturn’s moons.

Looks like we will need to make sure we look closely at this moon for the new Star Control.

There are some very interesting articles and videos at just how terrifyingly it would be if it turns out life is pretty common. Because if that’s the case, where is everyone?

Besides humans there are two other intelligences on Earth. One are the cetaceans. Whales, Dolphins, in other words mammals that live in the ocean. The second is a species of cephalopods i.e. Octopi. A vertebrate and an invertebrate. On the one exoplanet they believe to be a water world cetaceans could be the dominant life form. On another perhaps an invertebrate species may evolve. Any planet that harbors life will have life forms dictated by their environment, just like Earth. Depending on how long these life forms have existed, ours by example took forty thousand years give or take, others can evolve just as much and attain sentience. Intelligent life should be a forgone conclusion considering the sheer immensity of the cosmos.

The Australian Aborigine has been around longer than that...

"The first Aboriginal genome sequence confirms Australia's native people left Africa 75,000 years ago."

It's not that it isn't possible to do a flash Gordon style get in a rocket, and fly to alpha centauri be in an ok about six years. It is just way to expensive the us doesn't have enough money. No country does. It would take all the money. Warping... Would just make it affordable.

Remember the more complex the life the more several exponentially unlikely it is to happen.

This is only part of it. If astrobiology is correct then there are different liferorms based on different structures. If this is true then a planet covered with water could be more inhospitable thanks desert. Carbon is radioactive which means anything not made of carbon would be walking into a radioactive environment.

Not necessarily. Aside from carbon the next closest analogy for life is silica. A silicon based life form for example could thrive on a planet whose surface temperature would be hostile to carbon based life forms.

Carbon 12 is not radioactive.  Nor is the much rarer Carbon 13.  Carbon 14 is radioactive.  Which isotope you are talking about matters.

on Jul 04, 2018

Yes as Carbon 14 has a known rate of decay which allows organic objects to be dated. Inorganic objects are more difficult to date. Stable isotopes such as carbon 12 do not decay, they age, because if it did we wouldn't be here. Carbon, being among the most plentiful molecules, may allow for other forms of intelligent life out there. If you look at all the diverse life forms on Earth, all carbon based, I believe there's no real limit to how many others there could possibly be.

Ok the carbon we are made out of is it radioactive.

on Jul 04, 2018

About 99% of the carbon in your body is the non-radioactive carbon 12.  About 1% is the non-radioactive carbon 13.  You have some very small amount of the radioactive carbon 14, which has a half life of 5700 years.  Carbon 14 is produced naturally in the upper atmosphere when cosmic rays react with nitrogen 14 atoms.

Pretty much.

Quoting starkers,

As for ET's not making official contact as yet.... we are not intelligent enough [see above paragraph] to welcome ET here.  Maybe when we stop behaving like primitives with tribal mentalities?

Here's another scenario. Perhaps there are other human cultures out there who look at Earth and wonder..."Of all the human cultures we know, Terrans (Earth humans) are the only ones who prey upon themselves."


Or maybe these other cultures are exactly like us[e digicons]O[/e]  


Have any of you read the chinese scifi series Remembrance of Earth´s Past? It does concern the contact with alien civilization and it is really, really good, perhaps even better than Expanse.  Apparently Amazon intends to make the TV show from it for some heavy money - that would be beyond awesome.

The half-life of uranium-238 is about 4.47 billion years

according to what I've read, I wonder if we would live longer

if we had some small amount of uranium-238 in us?

Well we probably do. [e digicons]:cylon:[/e]

Nope. You'd live long enough for the first decay and're done. Think of it this way, 1 gram of U-235 gets you 24,000 KWh of heat. In terms of yield and depending on the method of conversion used, fission being the only one that works for now, a gram would carve out a pretty large hole in the ground with you at ground zero.
