The Unsettling Explanation Of The Dark Forest Hypothesis: Why Aliens Haven’t Made Contact

You have probably heard of the Fermi Paradox, but if you haven’t, here it is in a nutshell: Given the high probability that alien life exists out there in the universe (bearing in mind the vastness of space and that we keep finding planets within habitable zones) why has nobody got in touch yet? If there are so many other civilizations out there, possibly at far more advanced stages than we are because of how long the universe has dragged on, surely at least one would send out messages or probes, or do what we are doing: Desperately searching for signs of life?

Answers to the paradox range from the optimistic to the downright frightening. It could be that we simply haven’t been looking long enough, nor emitting our own traceable signatures for aliens to find us yet. Or it could be that no aliens will ever make it to the point where they are able to make contact with other species, destroying themselves long before they get to the kind of tech required to do so.

New Evolution Theory Explains Why Animals Shrink Over Time

New research reveals key factors behind the changing sizes of certain animals over time, challenging traditional evolutionary theories with its findings on species ’ size variations.

The mystery behind why Alaskan horses, cryptodiran turtles, and island lizards shrunk over time may have been solved in a new study.

The new theoretical research proposes that animal size over time depends on two key ecological factors: the intensity of direct competition for resources between species, and the risk of extinction from the environment.

North Korea Claims Successful Hydrogen Bomb Test

Year 2017

North Korea claims it has again tested a hydrogen bomb underground and that it “successfully” loaded it onto the tip of an intercontinental ballistic missile, a claim that if true, crosses a “red line” drawn by South Korea’s president last month.

In a state media announcement, North Korea confirmed the afternoon tremors in its northeast were indeed caused by the test of a nuclear device, and that leader Kim Jong Un personally signed off on the test.

“North Korea has conducted a major Nuclear Test. Their words and actions continue to be very hostile and dangerous to the United States,” President Trump tweeted Sunday morning in response. “North Korea is a rogue nation which has become a great threat and embarrassment to China, which is trying to help but with little success.”
