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.

You are assuming that we know everything about physics. That is probably not the case.
LIES. If they did, we will NEVER KNOW about them.
I thought Jim Adler was the “Texas Hammer”
and they showed us how to get ahead by using Fossil Fuels ,LOL
I’ve been in a Denny’s in Rhode Island, and won’t be back. There is no proof I was ever there. Does that mean I don’t exist?
A civilization that develops the technology to achieve interstellar travel would also have the technology to destroy themselves.
Do the math.
Once they were able to produce nuclear weapons, they all blew themselves up.
The result of most studies: “More study needed”.
No, it just means you have good taste..................
And full of preservatives.
why we haven’t found signs of intelligent extraterrestrials in our galaxy.
Once they could leave, they did.
Perhaps that's why we don't see aliens, anymore. The planet was sticky...
IHOP..........................
Life lesson from Planet Of The Apes.
This article is not unmeaningless.
Readers of “The Hitchhikers Guide to the Galaxy” will understand right off. The rest of you will have to puzzle through the meaning of, “not unmeaningless”. Took me a while when reading “Hitchhikers”.
They need to believe in aliens and that travel between stars is possible, otherwise we’re stuck here and the whole universe is just a massive backdrop for our existence that makes no logical sense from a materialist point of view.
I made a good living using Newtonian physics throughout my job as a mechanical engineer. Probably know as much applied physics as any one.
