We haven't found aliens because they're aren't any

[DigitalDrifter]

We can't even say for certain that life doesn't exist /in/ our solar system, we can only [maybe] just /barely/ even rule it out /present/ life on our nearest planet Mars (we cannot rule out ancient life on Mars yet.) Just because aliens are not using a technology /we/ might be able to detect (which consists of radio waves lol) doesn't mean jack. SETI is nice and all, but looking at it realistically, I have little doubt that "radio" is going to go away on Earth before too long, then really the only long distance indicators of life on Earth will be physical objects like satellites and probes, or if we destroy ourselves nukes. Outside of that one would have to get close enough to see satellites in orbit, see the lights at night, etc., so basically have to just happen upon the planet with life while passing through the solar system.

We've found amino acids (the building block for life) on asteroids, we've found liquid water on asteroids, and we've found ocean moons heated by tidal friction that could possibly support life, and that's without leaving our solar system at all - even by our present narrow-minded and egotistical standard's of where life could exist there are potentially billions perhaps trillions of planets and moons that could support life, and that's not even getting outside of the box of carbon based life as we know it. It makes no logical, nor statistical, sense that there isn't life out there somewhere else. We've barely got a handle on detecting Earth sized planets around other suns, and as far as I know we can't find Mars size planets yet, much less all the moons.

Anyone trying to say they /know/ anything about the existence of life off the planet Earth itself is basically full of crap. heh

The odds would appear to be so overwhelming that there is life throughout the universe, that it seems ridiculous to suggest otherwise.

That's what makes these claims so fascinating. We have very intelligent people here contradicting what most of us would assume has to be true.

Here recently in the U.S we had this lottery prize that had grown to over a billion dollars.
Many if not most of us bought at least one ticket, yet we all could pretty much safely say we had zilch chance to win.
It's as if a very intelligent person came up to you and said, you will win, it would be a fluke if you did NOT win.

It may seem stupid to us that any scientist would make a claim that life almost assuredly does not exist elsewhere, but what we should be asking is why does their research suggest this claim ?

Nice pic to remind us how enormous our unknown universe is! That galaxy may contain a billion stars, and there may be billions of such galaxies ... and billions of clusters of these galaxies, etc.
.

And what's really fascinating, is now astronomers say planetary systems are common, in fact they now say most stars have planets.
Furthermore, they say in the Milky Way alone there are billions of stars that each have one to three planets in the so-called Goldilocks Zone.

And yet, you have some scientists pouring cold water on the idea of life elsewhere.
On the surface, that seems insane, but I'm not an astrophysicist with my own research to debunk their claims.
All's I can do is point to the odds, and claim they are nuts.

Hubble Deep Field shows "only" about 3,000 galaxies ... and It covers only about one 24-millionth of the whole sky, which is equivalent in angular size to a 65 mm tennis ball at a distance of 100 meters:
LOTS OF STUFF OUT THERE WE HAVE NO IDEA ABOUT.
Therefore, the "theory" some astrobiologists are trying to propagate, called "Gaian Bottleneck model", is extremely premature & of the faith variety, in my opinion.

Our signals have only gone out 70 light years at most. If someone that far got it totday it would take 70 years for a signal to get back here. Our own galaxy is 100,000 light years side to side. There are billions and billions of galaxies in the universe. It's just really big. I have no doubt there's some kind of life out there, it's just very far away. Even in sci fi they need to make up stuff like sub space to make communication possible, because the speed of light isn't very fast when we are talking about the distances involved in the universe.

Life on earth is a mathematical impossibility.

That's like saying you have experienced mathematical infinity.
.

Well actually, if one considers a Big Bang happening, the odds that this earth just happened to become placed in a position whereby it could support life as we know it and also have all the right condition to support this life as we know it is in itself a stretch. If one further does the math, the odds of a single cell lifeform springing forth from some slime pool is practically an impossibility. The mathematical probability of a single cell mutating into a two or more celled lifeform is beyond the pale of any expectation.

It's not just life forming but surviving a million years. It only takes one environmental disaster to wipe out all the progress that has been made

If there is more advanced life out there it is probably best that it doesn't find us. We may not fare so well with such an encounter. Hawking even considered this when the message and invitation was put on the Voyageur 1 spacecraft. The silence at this point is actually a good thing.

If Voyager is ever found, we will be extinct by that time

Could go both ways.
If advanced intelligent aliens are powerful enough to reach us, they could play the role of a "benevolent God" ... for their own amusement.

Until recently we thought stars were just other stars. Turns out some of those lights in the sky are entire galaxies. Amazing.

I think all this alien talk is due to galaxy warming.

I think all this alien talk is due to galaxy warming.

Combined with climate change.

It appears no one wants to consider all that, but it is pretty clear to me that “probability” is not the non-intelligent design evolutionist’s friend. They seem more focused on the number of years the universe has been around and the amazing number stars (70 sextillion latest estimates) and the vastness of it all. IOW, "there must be intelligent life elsewhere, given all that." No, not really. A rock by any other name is still a rock.


>>The Laws of Probability. The average protein contains 400 amino acids of 20 different kinds arranged in precise sequence. Even 100 amino acids of 20 different kinds can be arranged in [20 to the 100th power] different ways. There are only [10 to the 80th power] particles in the entire Universe. If 100 amino acids were arranged randomly a trillion times per second for five billion years, the probability of them being arranged just once in a predetermined order is essentially nil. In order to have even the slightest possibility an evolutionary origin of life in an ocean containing 355 million cubic miles of water would require many billions of tons each of hundreds of different protein molecules and hundreds of different DNA and RNA molecules. Before the existence of life there could be no reproduction and thus no natural selection. All of this must occur by pure chance. A naturalistic, mechanistic evolutionary origin of life would be impossible.<<

Eureka!!! I have discovered intelligent life on USMB.

That's the classic paradox. We all want there to be other life out there, but if it finds us before we find it, that means it's much more advanced and we are likely to be at the mercy of it.

We are so far apart, we will never find each other

Or later than 92% of other planets or somewhere in the middle.

Yes yes I'm quite aware of that, you damn liberals are so fucking weird, we'll never agree on anything, I wish all of you would.........................................

Ohhhhhhhh, you meant the aliens !!


Nevermind.
