NASA too announced existence of Intelligent Life?

It is not philosophy. But indeed you can not use it to calculate any realistic number for likelihood. It just shows a number of factors that go into the likelihood. Some of the factors keep getting changed.

We did not know how likely planets are. Discovery of planets have pushed that factor way up.

Our understanding, where life may form have been pushed up as well with the discovery of liquid water on outer moons. Life could have evolved there, not only on earth like planets. So that factor went up.

But in a way the Fermi paradox is much more puzzling. Why if life is everywhere have we not found any signs of intelligence out there? Of course life is one thing, evolving to intelligence another. Also even intelligence does not mean a technological society that leaves signs we can detect. There is also the question, when technological society developes, how long will it last?

Maybe not long enough. The emergence of president Trump is a strong sign it may not last long at all. Not that Trump is a danger, but the fact that he can rise to presidency seems to indicate a deep flaw in society overall.

Life is probably all over the place - where there is liquid water and an energy source.

The chance of this evolving to intelligent life that is on par and above that of humans is probably extremely rare. But with the numbers involved there are, or were, or will be many, many, many intelligent civilizations throughout each galaxy. The issue about contact is distance and time.

How to explore and communicate over such extreme distances at the same time that another intelligent civilization is there to receive it.

Only true for our limited perception of life.

Again, it comes down to our perceptions or understanding of intelligence and civilization.

Although the Star Trek franchises explored some weird possibilities, and often touched on the comms issue, it barely scratched the surface. That's without even examining the possibilities of other dimensions, which actually start to sound like conspiracy theories and make my small brain hurt.

Don't doubt that last part...

True....

ET lives on the moon.

He won't let us Terras stay there.....we've been warned.

One problem is distance, yes. But the other, equally important, is time. Over a billion years there will be many, I agree. But how long does a technological society last? If, say, 10,000 years the chances are rare, that even 2 exist in the same time in one galaxy. For civilizations to meet their survival time needs to be in the millions of years. It does not look very good for that prospect.

For that to actually happen, a species needs to spread out. First interplanetary and then interstellar. The second is hard.

Sure, time (on a grand scale) and distance (on a incomprehensible scale.)

As technology develops its speed increases. The technological singularity isn't far away.

The first human to ever fly, could have met the first human to land on the moon.

Once there is a technological breakthrough, it can really take off (pardon the pun.

)

If it happens, yes. I am not sure. But even then the laws of physics limit what can be done. Maybe we do not know those limits yet.

Are you saying there might even be an end in sight for Cold Pizza's vegetative state?

**chassamui** · 28-06-2017, 07:25 PM

I'm so happy that I am not a vegetablearian.

We certainly don't.

There is always hope. There is ongoing work on neural networks. Direct interconnection of the brain with a computer. It may initially be good only for limited interaction but ultimately a full computer-brain interface.

I have seen a thread in the NSF forum. Another hoax seems to go around. I can not link to the thread as the nonsens seems to be deleted. Some 10 year old photos by Spirit or Opportunity rover that inspected landing gear of their own mission was declared as new photos by the Curiosity rover showing an alien spacecraft.

Maybe that is the source of this alien announcement by NASA?
