Data science is dead.

The right use is to learn truth through investigation of information via collection and numeric analysis (now at large scale thanks to modern computing).

Instead the field is entirely perverted and used most often to start with a fixed political ‘result’ and arrange both the information and the analysis to fit the agenda.

Yes, but it’s still interesting to wonder about.

The sun is “good” for many millions more years.

Will human civilization last as long as our sun?

I doubt it.

Well, we are working really hard to exterminate our species so the premise is not hard to understand.

Another effort at explaining away the Fermi Paradox. We are alone, and they know it, but can’t accept it because... God becomes a reasonable answer.

Exactly.

Powerful aliens are a God substitute, in many ways.

Most of the alien civilizations that ever dotted our galaxy have probably killed themselves off already. >>>>>>>>>>>

Unless we have star/ time travel, we likely will not be able to meet them.

Increasing evidence likely shows that some of them are already here, having mastered the technology of star/time travel.What remains t be seen is what their agenda truly is in relation to our world.

Unlike many, I personally would not assume their presence on earth is benevolent.They likely have been here for millennia on our time scale.

From the article:

Most of these other civilizations that still exist in the galaxy today are likely young, due to the probability that intelligent life is fairly likely to eradicate itself over long timescales.

Even if the galaxy reached its civilizational peak more than 5 billion years ago, most of the civilizations that were around then have likely self-annihilated, the researchers found.

Pretty wide-ass assumption to make with zero supporting evidence. Someone's got a real mean pessimistic streak in their thinking and their programming. GIGO...

I didn’t realize how far Socialism had spread. Pity.


I think the wrong ideology could destroy intelligent civilizations (or intelligence itself) just as effectively as nuclear war. Slavish & blind adherence to political correctness could cause us to devolve. While we associate advanced technology with progress, it could also create such a secure & prosperous environment that we begin to get stupid. Then when the tech fails (for some reason), we can’t do anything about it. Sci-fi is actually full of stories like this — some of them quite old (such as “The Machine Stops”, written in 1909 by EM Forster).

Does intelligent life exist elsewhere in the universe? It's highly unlikely, say scientists

Is there anyone out there? This is an age-old question that researchers have now shed new light on with a study that suggests intelligent life is “exceptionally rare” in the universe. Life on Earth has undergone a number of major “evolutionary transitions,” and some transitions seem to have occurred only once in Earth’s history, says the team from the University of Oxford. They contend that, in a universe that is over 13 billion years old, on a planet that is about 4.5 billion years old, it took all this time for multiple processes of evolution to result in life forms. Hence, the likelihood of such a favorable series of chance events happening is less probable.

Many of the heavier elements that are absolutely required to form a rocky planet as opposed to a gas giant simply were not available in enough quantity in the first few billion years of the 13 billion lifespan of the universe. These heavier elements are also necessary for life and complex systems that need to exist before anything sentient can make it to consciousness. So, the timing for thousands of previous (meaning before us) civilizations coming into existence wasn't there.

The universe just wasn't ready yet, and it appears we got here as fast as we could.

Hard to believe Humans will exist for another couple of million years.

Maybe our descendants.

It could be we will populate the universe.

That might be God's plan.

It appears the level of Man's intellect has been pretty steady for many thousands of years.

Hundreds of thousands...???

Millions... very doubtful.

We will become something else. Both Christianity and Science are fairly clear about that.

they will, lol

have you ever thought that maybe we might well be planet Australia.

and that is why we are the original sinners?

Is this “modeling” produced by the same group of morons that produced the global warming “modeling”?

Nuclear Holocaust and climate change are nothing compared to runaway wokesterism. That kills everything it touches.

“Maybe Ancient Aliens will do an episode on this. For some strange reason, I love that show!!”

I know what you mean. There is something about conspiracy theories that I find very entertaining. They are (mostly) fiction just like any other, except that the players are not acting, they actually believe the stuff. I suppose that adds another dimension of interest.

Aliens cause global warming, a classic speech by Michael Crichton explains the meaninglessness of the Drake equation. Caltech has fallen apparently.

This is not science.
It is pure speculation, based on numerous assumptions.

Agreed. "Researchers" have a sample size of exactly one - humans - on one planet. That's a pretty poor statistical sample for what, about 100 billion stars in the galaxy?

Consider. First, the 100 billion number is just an estimate, no-one has actually counted them.

How many of those stars have planets orbiting them? Another estimate. As our technology and techniques have improved this guess, er, estimate has continued to change.

How many of those planets orbiting stars are in the "habitable zone?" Another guess.

How many of those planets in the habitable zones have the right elements in the right proportions to support life? Another guess.

How many of those planets have actually experienced life? Another guess.

On how many of those planets has intelligent life occurred? Another guess.

On how many of those planets has mere intelligent life evolved into civilizations? Another guess.

Finally, we get to the apparent reason for their "research" - on how many of those planets have these civilizations fallen. Another guess.

In the end, you can find fairly intelligent, well-reasoned arguments that the galaxy is teaming with intelligent life, or that it is a barren void, and just about any position in between. The real takeaway is we simply do not know and have no way of knowing - yet.

Just a couple weeks ago, I read a more specific article at SciTechDaily about planetary survival in the Milky Way.

Less than 10% of the stars in this galaxy are similar to our own sun.

Most of the stars in the Milky Way are larger and more energetic.

Those stars have many more solar storms, and those storms are much more powerful than the storms on our sun.

Even planets that have a robust magnetic field like Earth would have their atmosphere stripped away in relatively short order by the more intense solar storms.
