Could “Rogue Planets” Hold the Key to Extraterrestrial Life?

A new paper asks us to think about the possibilities of planets that have been kicked out of a predictable orbit.

A new paper asks us to think about the possibilities of planets that have been kicked out of a predictable orbit: In a new paper, Alberto Fairén from the Center of Astrobiology in Madrid, Spain, and I look into the possibility that planets wandering through interstellar space could also host life. These “rogue” planets may have been ejected out of their original solar system during the early, chaotic phase of planetary formation. There are two general types of rogue planets: gas giants like Saturn and Neptune, and rocky Earthlike planets. While the chances for life on gas giants is extremely remote, rocky migrating planets could in principle host microbial life. To do that, they would need internal heat from the…

Cornell: Earth Could Be Seen by ET Far More Easily Than Thought

Using analytic software, researchers can determine whether Earth would be visible from a given star system

According to Cornell and American Museum of Natural History researchers, “Scientists have identified 2,034 nearby star-systems — within the small cosmic distance of 326 light-years — that could find Earth merely by watching our pale blue dot cross our sun”: Scientists at Cornell University and the American Museum of Natural History have identified 2,034 nearby star-systems — within the small cosmic distance of 326 light-years — that could find Earth merely by watching our pale blue dot cross our sun. That’s 1,715 star-systems that could have spotted Earth since human civilization blossomed about 5,000 years ago, and 319 more star-systems that will be added over the next 5,000 years. Exoplanets around these nearby stars have a cosmic front-row seat to…

What If We Don’t See Aliens Because They Have Not Evolved Yet?

If so, not only did we emerge during a favorable time in the universe’s history but we could end up suppressing them

Readers will recall that we have been looking at science writer Matt Williams’s analysis of the various reasons offered as to why we do not see extraterrestrials except at the movies. Last week, we looked at the Brief Window hypothesis (there is only a comparatively short period of time during which a civilization could make such contact). But there is another, darker possibility: We are ahead of them. And if we are not careful, we could end up suppressing them. That’s the Firstborn hypothesis: The universe has only begun to be hospitable to intelligent life and humans are among the first to benefit from that fact. The current model of the universe shows it radiating from the Big Bang over…

The Rare Earth hypothesis offers science-based reasons that life in the universe is rare

Recently, science and science fiction writer Matt Williams has been writing a series at Universe Today on why extraterrestrial intelligences never make contact with us. Last week, we looked at the hypothesis that, to avoid the heat destruction of their advanced technology, the aliens have put themselves into a digital slumber until the universe cools down. This week, let’s look at a quite different approach, which Williams outlines in “Beyond “Fermi’s Paradox” IV: What is the Rare Earth Hypothesis?” (July 29, 2020): That is “the possibility that life-bearing planets like Earth are just very rare.” We don’t see aliens because they are very uncommon: This is what is popularly known as the “Rare Earth Hypothesis,” which argues that the emergence…

Believers in God Detect Patterns More Easily

Psychologists found that both devout Christians and Muslims unconsciously detected patterns in a test more quickly

Researchers at Georgetown University Medical Center wanted to know “why and how brains come to believe in gods.” They explored that question using a concept in psychology called implicit pattern learning. Explicit learning is conscious but implicit learning is unconscious. For example, explicit learning is mastering the times tables in arithmetic class. Implicit learning is absorbing, without consciously thinking about it, the way the teacher treats others. The researchers’ hypothesis was: “people whose brains are good at subconsciously discerning patterns in their environment may ascribe those patterns to the hand of a higher power” To test that, they studied people who believe in God in the United States and in Afghanistan, using a conventional test for unconscious pattern learning: For…

Seven Reasons (So Far) Why the Aliens Never Show Up

Some experts think they became AI and some that they were killed by their AI but others say they never existed. Who's most likely right?

Science fiction author Matt Williams is writing a series at Universe Today that offers the leading explanations for why They never write, They never phone… It’s based on an incident in 1950 when Italian physicist Enrico Fermi (1901–1954) asked colleagues at the Los Alamos National Laboratory a question: If space aliens are a sure thing, “Where is everybody?” As Seth Shostak puts it at Search for Extraterrestrial Intelligence (SETI), The remark came while Fermi was discussing with his mealtime mates the possibility that many sophisticated societies populate the Galaxy. They thought it reasonable to assume that we have a lot of cosmic company. But somewhere between one sentence and the next, Fermi’s supple brain realized that if this was true,…

Is Intelligence Common or Rare in the Universe?

A recent analysis says that life is common but intelligence not so much. Let’s explore the reasoning

We really don't know anything about life elsewhere in the universe so even university-trained scientists often try to WISH it into existence.
