Given the U.S. propensity for religiousity, perhaps another effort is searching the universe for God?

dude, if you think the US ranks even near the top 25 countries in terms of religiosity then you need to travel more

While that is true as a percentage of the population, as for total number of religious people the US is in the top 5 just due to population size. [1]

Also, some US states are larger than entire countries and the percentages vary greatly by state. So depending on where you live in the United States it may feel like literally everyone is religious.

I live in a relatively liberal part of the country and I still feel the need to stay in the closet as an atheist for fear or being disowned by my community and family.

But back to the topic at hand, I think finding aliens would be definitive proof that at the very least the part about God creating earth as something unique and special is bogus.

In other words I think the origional poster is completely wrong. If you believe in God you should fear finding aliens. Philosophically many religious people have trouble reconciling with evolution, never mind another living creature on a planet other than our own.

Because Europe is a malaised society that lost its vigor, its lust for glory and adventure, long ago.

America hasn't exactly helped Europe out by displacing millions of refugees and creating a humanitarian crisis on their door step. Not to mention doing practically nothing to tackle climate change for the last 30 years. Sure Europe is in a difficult place right now, but who knows, they might emerge beter off and more ready for space exploration down the track?

wrt climate change, any plan that excludes China and India is short sighted and wrong, which almost every proposed plan has done. Beyond this, the U.S. would do more to reduce emissions by eliminating "express/air" delivery services.

Most plans/suggestions don't even look at the economics, or secondary factors. Like open-mining of rare minerals, mercury, etc in the mfg of low-energy light bulbs.

I'm all for reducing pollution and waste... I have a hyper-sensitive sense of smell, and the smog even in Phx is getting to be too much, let alone other cities I've been to. And, littering in general just pisses me off... but having 4-5 containers for recycling to sort things into, and then having that basically be a jobs program for sorters, when in the end most of it is still land-filled is a bit wasteful in itself.

There needs to be some pragmatism in terms of getting the biggest bang for the buck, and ineffective feel-good programs aren't the way to do get real impacting change.

In terms of trade, not allowing trade with countries that don't meet or exceed U.S. quality of life requirements for workers would be a start. Disallowing diesel ships the ability to dock in U.S. ports over the next decade would do a lot as well. Disallowing airmail transport of packages, or heavily taxing would help a lot too.

Tax credits for hiring employees with less than a 20 minute commute could also go a long way too. Include employees able to work from home at least 60% of the time.

Enacting a national energy tax on companies with over 1000 employees could be a large impact as well.

It's possible to do a lot of these things without creating a lot of hard to manage subsidies that will exist long beyond the reasons for making them in the first place.

I am Swedish and interested.

There is 100-200 billion galaxies. The estimated number of stars in the universe is between 10^22 to 10^24. Each star on average has more than planet in orbit. That means its at lest 10^22 planets. 10000000000000000000000. Whats the probability we are the only one with intelligent life on it?

We should work together in peace to discover these new planets.

None of those are related to Europe's malaise. The fire that drives people to build great things, to push themselves harder, to try to make a better life for themselves, has been extinguished in Europeans.

While I definitely don't exclude the possibility of life on other planets, I don't think we have yet any way to calculate the probability of its existence.

I can think of two possibilities to estimate the probability of life outside earth. The first requires knowing, given set of planets excluding earth, how many of them have life on them. We obviously can't use this method yet.

Another method is knowing exactly what it takes to create life and then calculating the probability of this process occurring outside earth.

We haven't yet managed to synthesise life in a lab (despite headlines which try to claim the contrary). This does not mean we won't be able to create it eventually, but the fact remains that can't yet assess what more is left to make it work. Therefore, you can't assess the probability for it to work anywhere else.

Bottom line, I can see no serious formula (Drake's or other) which can give us any estimate at the moment.

I am going to take the opposing view here on the likelihood of extraterrestrial life. But I do want to say that I think it is good someone is out there looking for it. I have been known to be wrong quite a bit.

I don't think 10^22 is a very big number. If we try to guess the probability of life evolving at random, I can see it being negligible given that number of planets.

First we can try to calculate something easier, the famous monkeys banging on keyboards to try to type Hamlet. If we put 1 trillion monkeys on each planet, and let them try for a trillion years, with three attempts per day to make the math easier, we get a total of 10^49 attempts.

We'll consider a keyboard with 50 keys. 10^49 is roughly 50^29, which means we can expect one lucky monkey to get 29 characters into the play. That is impressive but not very far into a play with 30,557 words (150,000 characters?). (http://www.opensourceshakespeare.org/views/plays/plays_numwo...)

Now consider human DNA. I am not a biology expert so I may not have my DNA right. But it looks like a typical human DNA molecule contains 500,000 to 2,500,000 nucleotides (http://wow-really.blogspot.com/2006/11/your-dna-would-reach-...). I believe there are 4 possibilities for each nulceotide. That means 4^2,500,000 or 10^1,500,000. That is a lot of possibilities. Worse even then typing Hamlet. And that would be if we just had monkeys supplied with adenine, guanine, cytosine and thymine putting DNA together. Never mind that these are each complicated molecules in themselves that have to be assembled at random.

So how did we even get here? Well, thanks to quantum mechanics we have almost endless opportunities to end up here. It just seems unlikely that we and some other life ended up in the universe together.

I seriously doubt we will ever encounter intelligent extraterrestrial life. There are a lot of obstacles - the distances involved, the fragility of life, and the fact that not every intelligent life-form will develop advanced technology.

All that said, I am certain it such life exists elsewhere.

I think the chemical reactions that could possibly give rise to life probably happen many many many orders of magnitude more often than 3 times per day.

I used to have a simplistic religious belief and a "worldly" one, but over time they have converged into one thing.

My understanding is that everything in the known universe is subject to time and light. Light is subject to time.

Looking at the number of planets, the probability of life is very high, intelligent life, I don't know. The problem for me is that if aliens exist on say the Sombrero Galaxy, a planet that we could "see" would probably be extinct or much more evolved in our 2017 AD. The Sombrero is 29 million light-years away. If hypothetically intelligent life exists on Sombrero, and we can prove it; would we be proving its existence millions of years ago?

Given that the fastest thing in the universe is light, and as it has a measured speed, it's subject to time. I don't think we'll ever discover modern-day life forms. Even teleportation would somehow be subject to the speed of light. I was fascinated the day I learnt that we technically can't even leave The Milky Way because it's so huge! So how will we find aliens, or they find us?

This is of course a layman argument. If someone with knowledge corrects me, I'd be delighted to spend my morning reading and expanding my knowledge!
