That would require the Earth to be very very special indeed, and I just don't see it.

Not at all. For example, I just generated a random number between 1 and 1e9. It was 869,502,332. By your logic, therefore, that number must have been very, very special. But no, it was just really improbable and that number happened to come up.

It may very well be the same case with life. Life could just be extremely improbable, and Earth just happened to be "the number" that was picked. This is what the Anthropic Principle is all about. Our perceptions are colored by the fact that we're here, so we think, "Since the Earth is not special, therefore, other planets must have life like Earth." It might just be that Earth was the lottery winner.

I said this in another post, but I'll say it again: The best evidence against life being common is the fact that it only happened once on Earth. It's fairly conclusive that all life on Earth has a common ancestor. If abiogenesis were easy and common, it wouldn't just stop once it happened one time, it would happen continuously over the billions of years since it happened for us. But it didn't.

And honestly, life on Earth being completely unique in the universe isn't that hard for me to believe when I look at the utterly insane complexity of cellular machinery. But again, extreme improbability doesn't matter when we're deal with the anthropic principle. We don't sense how long it took for intelligent life to pop up, just like we didn't sense the 13 billion years until you and I were born to think about all this.

likely

We have zero evidence for life being likely, except wishful thinking in the form hand-waving like the utterly useless Drake equation. On the other hand, we do have some suggestive evidence that life itself is improbable. The biggest evidence is that, as near as we can determine, it only happened once on Earth. If life was probable, it should have continued to re-occur, but we're fairly certain that all life has a common ancestor.

I think you mean "wrong" rather than "dangerous". There is a limited impact to our having a wrong opinion on the matter.

This will help you out

Dumbass, improbable does not imply magical. That's the other problem with life being really improbable, a lot of science people get all uptight that the religionists are going to run around gleefully saying "HA!!! THE SCIENTISTS ADMIT GOD IS THE ONLY EXPLANATION!!!"

More like, "it's how it was in the beginning. We all know at this point it's a dumb idea and a huge mistake, and Reddit has proven that editing can work and work well, but we're too set in our ways to admit it's a mistake and thus we'll call it 'working as intended' and pretend that it serves a purpose."

Dammit. Reddit has spoiled me on submitting without having to make absolutely sure I didn't make any formatting mistakes and editing later. I wish Slashdot would come into the 21st century.

> I think life at the single cell level might be fairly common. I actually think the single cell is the hard part. People underestimate just how INSANELY complex single cell organisms are. I don't mean a little complex, I mean crazy complex. Look at this animation of DNA replication: https://www.youtube.com/watch?... One side is duplicated straightforwardly... the other side has to be taken apart, flipped around and reassembled... and this is only one example. It gets even crazier from there. We tend to think of cells as "simple life forms", but they mind-blowingly complicated machines. It would not shock me at all if there was no other example of single cells in the entire universe.

My personal opinion is that life is really, really, really, REALLY rare. It only seems like it ought to be common because of the Anthropic Principle. We're can observe ourselves and thus it seems like life is easy. But everything would be exactly the same if we were completely unique in the universe. In fact, if the universe were cyclic and it took 1e1035 universe cycles for life to happen, things would look exactly the same. We simply have no basis for knowing how probable it is. Given how insanely complex we are, I suspect that it's exceedingly rare.

He has hurt almost everyone in America far far worse than any environmental changes.

I try to be a normal guy, but these special interest groups that keep terrorising companies needs to stop. Perhaps it is time to start the same to those that give any money to Greenpeace. I wonder how they would like it if say their lifeblood (cash) was suddenly under constant attack, and they had to focus on defending that as opposed to doing the work they want to do. They say they have 2.9 million people who give them money. Perhaps it is time to show the top donors... well how about all their donor and then companies can start to decide if they want to employee people like that.

Crazy world.

 

With all due respect. Are you crazy? New taxes are never the solution. Ever. This is like helping someone who is addicted to cocaine, more cocaine! How about this, they truely balance the budget first, then we can argue about how we should spend the money. You want new roads, awesome, then we cut social security, medicare and medicate. I am all for it! There is nobody on this planet that is as inefficient as our government and thus giving them more money is akin to being insane.. Their only solution to problems is to tax more, yet spending never really goes down.

Next you bring up building new roads in other countries. We somewhat agree on that one, but it sure is sad to see this administration snatch defeat out of the jaws of victory. Could you imagine if we actually took the oil, and sold it for a profit? Then again all those crazy nuts who said the war was about oil could scream that they were right.

That's a fake video.

You say that like it's a bad thing. As far as I'm concerned, I love the fact that I can trade demographic data for various online services. I'd far rather give them that than have to shell out real money. And as a bonus, I get ads that are potentially actually useful to me, rather than (say) feminine hygiene products.

Major imagination fail. You have no idea what you're talking about. This is going to change the world on many, many levels. That's why FB bought them. I'm not going to bother to prove this for you, but just wait for it to happen.
