3001 The Final Odyssey- Prologue

Posted by in categories: alien life, evolution

Call them the Firstborn. Though they were not remotely human, they were flesh and blood, and when they looked out across the deeps of space, they felt awe, and wonder— and loneliness. As soon as they possessed the power, they began to seek for fellowship among the stars.

In their explorations, they encountered life in many forms, and watched the workings of evolution on a thousand worlds. They saw how often the first faint sparks of intelligence flickered and died in the cosmic night.

The Search for Life Off Earth Points to Mars

Posted by in categories: alien life, chemistry

The word “intriguing” is being used to describe Perseverance results coming from sedimentary rocks on Mars that are of the same type known for preserving fossils and evidence of life here on Earth.

When NASA landed the Perseverance rover on Mars complete with an instrument package capable of identifying organic molecules, the Agency chose the Jezero Crater, the site of an ancient water-formed delta dating back 3.5 billion Earth years. The goal was to look for signs of ancient Martians, not the Martians of H.G. Wells’ “War of the Worlds,” but rather microorganisms like the ones that killed off the Martians after they arrived.

Onboard Perseverance is an instrumentation package that goes by the acronym SHERLOC which stands for Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals. Using SHERLOC, Perseverance has been sampling sedimentary rocks laid down by the water that flowed on the Martian surface earlier in its history.

Our Universe Resides In the Center of a Black Hole, New Theory reveals

Posted by in categories: alien life, quantum physics

What’s our position in the universe? Some astronomers believe that the relative emptiness in our location in space may be why we haven’t found other intelligent life yet. It may even go beyond that. One theory states that our universe is actually trapped inside a giant black hole, which itself is part of a much larger cosmos.

It all centers on a very different theory of what exactly a black hole is. The usual general understanding is nothing can escape a black hole’s intense gravity, not even light. Called the black hole information paradox, it’s thought that even the information about an object that gets sucked in vanishes into oblivion. But therein lies a problem.

This understanding violates a certain rule in quantum mechanics known as “unitarity,” which states that information can never be completely lost. Some trace of it will always remain. So how can scientists get over the hump?

Strange Hexagonal Diamonds Found on Earth Came From Another World

Posted by in categories: alien life, particle physics

Four meteorites in northwest Africa were found to contain mysterious hexagonal diamonds that don’t naturally occur on Earth. Essentially, scientists exploring the contents of the space rocks discovered extraterrestrial materials, if you will, alien diamonds. According to Alan Salek, a member of the team that discovered the materials, “some people in the field doubted the existence of this material.” As with regular diamonds, hexagonal diamonds are made of carbon, but their atoms are arranged hexagonally rather than cubically.

The first hexagonal diamonds were recorded in meteorites in the United States and India in the 1960s and were dubbed lonsdaleite. The previously discovered crystals, however, were so small – only nanometres wide – that their hexagonality could not be confirmed. A powerful electron microscope was used by Salek and his colleagues to examine 18 meteorite samples in search of larger crystals. One of them was from Australia, and the other three were from northwestern Africa. It was found that four of the African meteorites contained hexagonal diamonds, some measuring up to a micrometer – about 1,000 times larger than anything previously discovered.

In this way, the team was able to confirm the hexagonal structure’s unusual characteristics. Salek says that now that they have larger crystals, they can get a better understanding of how they form and maybe replicate that process. Scientists are interested in Lonsdaleite since it might have even more industrial potential as a result of its theoretical hardness being stronger than a regular diamond. High-end saw blades, for instance, already contain regular diamonds.

Does Cosmic Fine-Tuning Demand Explanation? | Episode 1208 | Closer To Truth

Posted by in categories: alien life, physics

The universe works for us because of deep physical laws. But if the values of these laws change much, then all we see and know could not exist. If small changes to the laws of physics would make life impossible, does fine-tuning require an explanation? Featuring interviews with Bernard Carr, David Deutsch, Richard Swinburne, Rodney Holder, and Christopher Isham.

Season 12, Episode 8 — #CloserToTruth.

Potentially habitable “super-Earth” discovered 100 light-years away

Posted by in categories: alien life, physics

An international team of scientists announced on Wednesday that they have discovered two new “super-Earth” planets just 100 light-years away. Both of them are significantly larger than our own planet — and one of them may even be suitable for life.

Super-Earths are a unique class of exoplanet in the solar system that are more massive than our planet but lighter than the ice giants, according to NASA. They are made by some combination of gas and rock and can get up to 10 times the size of Earth’s mass.

The findings, discovered with NASA’s Transiting Exoplanet Survey Satellite and the University of Liège’s Search for Habitable Planets Eclipsing Ultra-Cool Stars (SPECULOOS), will be published in the journal Astronomy and Astrophysics.

We can spot life outside the solar system in the next 25 years, says astrophysicist

Posted by in categories: alien life, futurism

Work is afoot to build the necessary instruments to do so.

ETH Zurich, the Swiss federal institute, recently opened its new Center for the Origin and Prevalence of Life, an interdisciplinary institute to analyze the current and future observations of the Earth and the universe. During the opening ceremony, astrophysicist Sasha Quanz said that we might be able to detect the presence of life outside our solar system in the next 25 years,

Is the universe a graveyard? This theory suggests humanity may be alone

Posted by in category: alien life

Ever since we’ve had the technology, we’ve looked to the stars in search of alien life. It’s assumed that we’re looking because we want to find other life in the universe, but what if we’re looking to make sure there isn’t any?

61 years ago, the founding father of SETI fundamentally altered the search for aliens

Posted by in categories: alien life, information science, physics

This places Drake in the company of towering physicists with equations named after them, including James Clerk Maxwell and Erwin Schrödinger. Unlike those, Drake’s equation does not encapsulate a law of nature. Instead, it combines some poorly known probabilities into an informed estimate.

Whatever reasonable values you feed into the equation (see image below), it is hard to avoid the conclusion that we shouldn’t be alone in the galaxy. Drake remained a proponent and a supporter of the search for extraterrestrial life throughout his days, but has his equation taught us anything?
