Could Self-Replicating Crystals in Space Be an Early Form of Inorganic Life?


Dustorb An international research team claimed a breakthrough in self-replicating plasma crystals which could be an early form of inorganic life. New studies of dust that form lifelike structures suggest that extraterrestrial life may not be carbon-based at all. Researchers at the Russian Academy of Science, the Max-Planck Institute for Extraterrestrial Physics in Germany, and the University of Sydney observed particles of inorganic dust form helical structures and go through other "lifelike" changes.

Undetectable Extraterrestrials? World-Leading Physicist Says "They Could Exist in Forms We Can't Conceive" (A Weekend Classic)


Greece-forest-fires-view-from-space-smoke-plumes-over-ocean-mediterranean-sea-satellite-image-nasa-earth-observatory-greek-greece-coastline-country-shape-ocean-photo The intriguing remark was made by Lord Martin Rees, a leading cosmologist and astrophysicist who is the president of Britain’s Royal Society and astronomer to the Queen of England. Rees, who last month hosted the National Science Academy’s first conference on the possibility of alien life, said he believes the existence of extra terrestrial life may be beyond human understanding.

“They could be staring us in the face and we just don’t recognize them. The problem is that we’re looking for something very much like us, assuming that they at least have something like the same mathematics and technology."

The Billion-Year Technology Gap: Implications for the Search for Extraterrestrial Life (A Galaxy Classic)

Minims-vatican-observatory (1)Are we the lone sentient life in the universe? So far, we have no evidence to the contrary, and yet the odds that not one single other planet has evolved intelligent life would appear, from a statistical standpoint, to be quite small. There are an estimated 250 billion (2.5 x 10¹¹ ) stars in the Milky Way alone, and over 70 sextillion (7 x 10²² ) in the visible universe, and many of them are surrounded by multiple planets.

"The Great Silence" -Stephen Hawking & Others Look At Why Life Has Yet to be Discovered Beyond Earth (Weekend Feature)

6a00d8341bf7f753ef011571f361f4970b-500wi "The idea that we are the only intelligent creatures in a cosmos of a hundred billion galaxies is so preposterous that there are very few astronomers today who would take it seriously. It is safest to assume therefore, that they are out there and to consider the manner in which this may impinge upon human society."

Arthur C. Clarke, physicist and author of 2001: A Space Odyssey

"The Great Silence" -Are Supernovas Destroyers of Life in the Universe?

6a00d8341bf7f753ef0120a7b37085970b-500wi The physicist Enrico Fermi once asked referring to visits to Earth by extraterrestrial civilizations: Where are they?The accurate answer might well be: destroyed by radiation from supernova explosions.

A massive white dwarf star in our galaxy may become a supernova several million years from now, and could possibly destroy life on Earth. 

Most astronomers today believe that one of the plausible reasons we have yet to detect intelligent life in the universe is due to the deadly effects of local supernova explosions that wipe out all life in a given region of a galaxy.

"Asteroid Impacts are the Biggest Threat to Advanced Life in the Milky Way" -Stephen Hawking (A Daily Galaxy 2009 Top Post)

D120ssc200501b2

Stephen Hawking believes that one of the major factors in the possible scarcity of intelligent life in our galaxy is the high probability of an asteroid or comet colliding with inhabited planets. We have observed, Hawking points out in Life in the Universe, the collision of a comet, Schumacher-Levi, with Jupiter (below), which produced a series of enormous fireballs, plumes many thousands of kilometers high, hot "bubbles" of gas in the atmosphere, and large dark "scars" on the atmosphere which had lifetimes on the order of weeks.

Stephen Hawking: "Why Isn't the Milky Way Crawling With Mechanical or Biological Life?" (A New Year's Weekend Classic)

Tropical_saturn

In his famous lecture on Life in the Universe, Stephen Hawking asks: "What are the chances that we will encounter some alien form of life, as we explore the galaxy?"

If the argument about the time scale for the appearance of life on Earth is correct, Hawking says "there ought to be many other stars, whose planets have life on them. Some of these stellar systems could have formed 5 billion years before the Earth. So why is the galaxy not crawling with self-designing mechanical or biological life forms?"

The Human Species' Urge for Contact - The Search for ET (VIDEO)

6a00d8341bf7f753ef0120a5f2acee970b-800wi

The search for extra-terrestrial life assumes two things: that there is some, and that it wants to talk, and while the first is obvious to anyone with even the remotest understanding of the size of the universe the second still poses a lot of questions. The fact is there's only one E.T. whose communications motives we ever understand, and all he wanted was to get off our crazy dirtball.  And we made him up.

Could an Inhabited Moon Like Pandora in James Cameron's "Avatar" Exist? Harvard-Smithsonian Astrophysics Team Says "Yes"

ArticleLarge

Imagine being roused by an attendant floating in zero gravity from a years-long sleep just before landing on a distant inhabited moon, Pandora. What you would soon discover is an exotic DNA carbon-based alien world.

The Billion-Year Technology Gap: Could One Exist? (The Weekend Feature)


Minims-vatican-observatory (1)Are we the lone sentient life in the universe? So far, we have no evidence to the contrary, and yet the odds that not one single other planet has evolved intelligent life would appear, from a statistical standpoint, to be quite small. There are an estimated 250 billion (2.5 x 10¹¹ ) stars in the Milky Way alone, and over 70 sextillion (7 x 10²² ) in the visible universe, and many of them are surrounded by multiple planets. 

Meanwhile, our 4.5 billion-year old Solar System exits in a universe that is estimated to be between 13.5 and 14 billion years old. Experts believe that there could be advanced civilizations out there that have existed for 1.8 gigayears (one gigayear = one billion years).
