The Milky Way could be teeming with extraterrestrial civilizations that have spread across the stars, a new study found. The study offers new perspectives on the Fermi paradox, which asks why we haven't found signs of intelligent extraterrestrials in our galaxy. There are plenty of scenarios in which aliens could exist but we haven't heard from them, the study's authors wrote. Aliens may have even visited Earth, they say — just not recently enough for us to have noticed. The study suggests that aliens might wait for stars to move closer to one another before spreading across the galaxy.
The Milky Way could be teeming with interstellar alien civilizations — we just don't know about it because they haven't paid us a visit in 10 million years.
A study published last month in The Astronomical Journal posits that intelligent extraterrestrial life could be taking its time to explore the galaxy, harnessing star systems' movement to make star-hopping easier.
The work is a new response to a question known as the Fermi paradox, which asks why we haven't detected signs of extraterrestrial intelligence.
The paradox was first posed by the physicist Enrico Fermi, who famously asked, "Where is everybody?" Gaia mapping the stars of the Milky Way
Fermi was questioning the feasibility of travel between stars, but since then his query has come to represent doubts about the very existence of extraterrestrials.
The astrophysicist Michael Hart explored the question formally when he argued in a 1975 paper that there had been plenty of time for intelligent life to colonize the Milky Way in the 13.6 billion years since the galaxy formed, yet we'd heard nothing from them. Hart concluded that there must be no other advanced civilizations in our galaxy.

Atheists need aliens to validate their worship of time and matter.
It would require 500 generations of humans breeding in a space station travelling at rocket speeds to reach the NEAREST star system to our solar system.
Problem with universe is it is extremely sparsely populated with astronomical distances between stars. We are never going to be visited by aliens. May be by a non-living computerized space ship could last to reach earth, but chances are less than 1 in Gazillion.
I think if you found some planet with a civilization only 1,000 years ahead of Earth...we might be able to grasp this and form some ‘talks’. But if you came into contact with some group who was 500,000 years ahead or 20-million years ahead...this talks-sequence won’t go far. It’d be like Earth exploration teams landing on some planet that was still in the 1500s-type time-period on Earth...why bother announcing yourself?
It’s a big-ass galaxy, and even over billions of years it’s hard to visit every place.
I saw a study once of a person who did the math who said that the chance of life meeting each other is like the odds of a few people living on earth meeting each other if they were the only people on the entire planet.
They sure do use the word “could” a lot.
[They sure do use the word “could” a lot.]
yeah, and hillary COULD be president... but she’s not.
It doesn’t help that as far as we are concerned, we ar living in the galactic boonies..................
I coulda been a contenda!................
To the Fermi paradox: there’s no sign of them in our galaxy because they banned plastic straws a long time ago. And their popsicle sticks have already decomposed without a trace.
Well the Earth is the only planet with Chocolate, so there is that.
The finished all the required anal probes on the planet earth and moved on. Some settled in San Francisco where that skill could become a passion.
The first error in fact or logic may just be the assumption/postulate that there has been 13.9 billions of years, the next may be that “there must be life elsewhere”.
Remove either of those requirements and voila, here we are!
Fermi was a wise man. Of course, arguing from a point of absence of evidence is unseemly to true believers in the absence of a Creator God....
After all these years, I’m surprised the scientists haven’t come up with a synthetic chocolate.............
Well, they consensus is wrong, because he WAS clearly referring to sentient, space-faring extraterrestrials.
The galaxy could be flush with single-cell like organisms.
His point was in the rare chance that some of these worlds go to multicellular life, and then led to a sentient species, and they managed to develop a space program, then were are they?
Scientist Frank Drake did the math. We know how big the Milky way is, and we know roughly how stars there are. If these aliens only settled a nearby star once every 1,000 years, then it would take approximately 100,000 years to spread across the ENTIRE Milky Way, where the Solar System we live on, is.
So Fermi asked, where are they?
Alien civilizations haven’t contacted us? Why would they? Contrary to convential wisdom, this is an insignificant planet in an insignificant solar system. Compared to any civilization able to navigate the stars, we are remarkably backward and not intelligent enough to warrant communication. Maybe in a couple of million years?
Monkeys may have flown out of my butt.
They left...Pelosi
Monkeys may have flown out of my butt.
Maybe the ‘Aliens’ have a Prime Directive:
Do not contact stupid civilizations...................
