Is our galaxy filled with dead civilizations ?

Has most intelligent alien life wiped itself out ? Image Credit: CC BY-SA 3.0 Luciano Mendez
A new study has suggested that most alien civilizations may have already destroyed themselves.
Finding evidence that we are not alone in the universe has been a life-long pursuit for many astronomers, despite the task being akin to searching for a needle in a haystack.

Now though, a new study written by three physicists from the California Institute of Technology ( as well as one school pupil ) has put forward the rather unfortunate conclusion that most of the intelligent alien civilizations in the Milky Way galaxy will have most likely destroyed themselves long ago.

The research involved a combination of modern astronomy and statistical modelling to calculate the emergence and destruction of intelligent civilizations over time.

The study has effectively produced what could be considered to be an updated version of the famous Drake equation - a formula created by astronomer Frank Drake and popularized by astronomer Carl Sagan which attempted to determine the number of intelligent extraterrestrial civilizations in our galaxy based on multiple factors such as the number of planets that form and how many of those develop life.
"Since Carl Sagan's time, there's been lots of research," said study co-author Jonathan H. Jiang.

"Especially since the Hubble Space Telescope and Kepler Space Telescope, we have lots of knowledge about the densities [of gas and stars] in the Milky Way galaxy and star formation rates and exoplanet formation ... and the occurrence rate of supernova explosions."

The study authors ultimately determined that any civilizations that do exist today in the Milky Way will be relatively young, with most of the older ones having already wiped themselves out.

They will also be situated mainly along a band of sun-like stars approximately 13,000 light-years from the galactic core.

Given that we have no idea how long it might take any given civilization to destroy itself, however, it would be fair to say that there is still a significant margin for error with these findings.

sorry my friend.. With all the deepest respect in the world= you ARE wrong! The vast VAST majority of humans are kind, caring, empathetic individuals who just want to live in peace with their family & friends. For every awful injustice/ horrendous act you hear in the media, there are millions of kind, caring acts happening every day. You just don't get to hear of them! I think us humans are bloody brilliant with regards to what we've achieved so far.... It's only a few that fek it up.. Peace, Sakari. dej...

Being facetious on that last one. I tend to use humor a lot. You can say I am wrong all you want. Your opinion is not law. No one can tell anyone their opinion is wrong. Although, kind of proves my point, doesn't it? You have not, and do not see what I see, and have, and do not see what you see. Not sure what your age is either, on life experience.My Mom had the same outlook as you a year ago. She now says the same thing I do. She says she does not think the majority of people care for anyone but themselves anymore. She is a born again Christian. She is pretty convinced the end is near. I trav... [More]

The people I know who feel this way are the ones doing the most damage to society and our planet. They've already determined that both are going to die no matter what they do so why bother saving them?

Its all a lie aliens are here they are here they been here. The universe is teaming with life. They try'n hide alot from us but if you really want to know you can find out. But trust me i suggest that you keep your minds to the ground because if you seek the truth on that topic you will find it. And you will be afraid beyond the grave cause you dont understand anything everything we know means nothing until you know the truth. Those of them that knows the truth keeps it away from us because we are a species of human ..... Please dont become afraid .... That needs to be controlled all we think ... [More]
