Let’s not use Mars as a backup planet

Posted by in category: alien life

Stellar astronomer and TED Senior Fellow Lucianne Walkowicz works on NASA’s Kepler mission, searching for places in the universe that could support life. So it’s worth a listen when she asks us to think carefully about Mars. In this short talk, she suggests that we stop dreaming of Mars as a place that we’ll eventually move to when we’ve messed up Earth, and to start thinking of planetary exploration and preservation of the Earth as two sides of the same goal. As she says, “The more you look for planets like Earth, the more you appreciate our own planet.”

Berserker hypothesis

Posted by in categories: alien life, existential risks

A more frightening implication of the fermi paradox.


The berserker hypothesis, also known as the deadly probes scenario, is the idea that humans have not yet detected intelligent alien life in the universe because it has been systematically destroyed by a series of lethal Von Neumann probes.[1][2] The hypothesis is named after the Berserker series of novels (1963−2005) written by Fred Saberhagen.[1]

The hypothesis has no single known proposer, and instead is thought to have emerged over time in response to the Hart–Tipler conjecture,[3] or the idea that an absence of detectable Von Neumann probes is contrapositive evidence that no intelligent life exists outside of the Sun’s Solar System. According to the berserker hypothesis, an absence of such probes is not evidence of life’s absence, since interstellar probes could “go berserk” and destroy other civilizations, before self-destructing.

In his 1983 paper “The Great Silence”, astronomer David Brin summarized the frightening implications of the berserker hypothesis: it is entirely compatible with all the facts and logic of the Fermi paradox, but would mean that there exists no intelligent life left to be discovered. In the worst-case scenario, humanity has already alerted others to its existence, and is next in line to be destroyed.[4].

Earth-sized planet found just 72 light years away

Posted by in category: alien life

The Earth-like planet is almost the same size as Earth, but it has a four-day year.

An international team of astronomers discovered a new planet that greatly resembles Earth in size.

The astronomers confirmed the existence of K2-415b, an exoplanet orbiting an M dwarf star some 72 light-years away from Earth, according to a press release.

Arrows of Time

Posted by in categories: alien life, physics

The human mind has long grappled with the elusive nature of time: what it is, how to record it, how it regulates life, and whether it exists as a fundamental building block of the universe. This timeline traces our evolving understanding of time through a history of observations in CULTURE, PHYSICS, TIMEKEEPING and BIOLOGY.

Australia’s first inhabitants, the ancestors of today’s aboriginal peoples, are believed to have embraced a timeless view of nature, in which the present and past are intimately connected. The spirits of long-dead ancestors, for example, were believed to inhabit the living. These spirits reflected a long-ago golden age sometimes known as the Dreamtime.
