Vladimir Putin’s Health Called Into Question After Russian Leader Looks ‘Critically Ill’ During Chilling Nuclear War Warning To Ukraine

Posted by in categories: existential risks, health, nuclear energy

Earth has been hit by an intense, unusual blast of light that could change our understanding of the universe, scientists have said.

Late last year, scientists spotted a 50-second-long blast of energy coming towards Earth, known as a gamma-ray burst or GRB, which are the most powerful explosions in the universe. Immediately, researchers started looking for the afterglow that such blasts leave behind, with that visible light being useful to find where the blast has come from.

The Fermi paradox: Are we alone in the universe?

Posted by in category: existential risks

Two possibilities exist: Either we are alone in the universe or we are not. Both are equally terrifying. ~Carl Sagan.

Looking up at a starry night sky makes one wonder if we are really alone. If you have never asked yourself this question, here’s some perspective on the vastness of our universe.

And this is just one galaxy.

Megatsunami on Mars linked to an asteroid strike 3.4 billion years ago

Posted by in categories: asteroid/comet impacts, existential risks, mapping

The event is likened to the Chicxulub collision on Earth.

A study has found that the megatsunami that swept Mars around 3.4 billion years ago was caused by an asteroid strike on one of its oceans. The event is compared to the likes of the Chicxulub collision—which is believed to have wiped out dinosaurs from the face of the earth about 66 million years ago.

Researchers, led by Alexis Rodriguez of the Planetary Science Institute in Arizona, have also suggested that NASA’s Viking 1 Lander, which was deployed on a mission to find evidence of life on Mars in 1976, could have landed near the crater of this megatsunami.

Cause of Cambrian Explosion — Terrestrial or Cosmic?

Posted by in categories: asteroid/comet impacts, biotech/medical, evolution, existential risks, genetics

We review the salient evidence consistent with or predicted by the Hoyle-Wickramasinghe (H-W) thesis of Cometary (Cosmic) Biology. Much of this physical and biological evidence is multifactorial. One particular focus are the recent studies which date the emergence of the complex retroviruses of vertebrate lines at or just before the Cambrian Explosion of ∼500 Ma. Such viruses are known to be plausibly associated with major evolutionary genomic processes. We believe this coincidence is not fortuitous but is consistent with a key prediction of H-W theory whereby major extinction-diversification evolutionary boundaries coincide with virus-bearing cometary-bolide bombardment events. A second focus is the remarkable evolution of intelligent complexity (Cephalopods) culminating in the emergence of the Octopus. A third focus concerns the micro-organism fossil evidence contained within meteorites as well as the detection in the upper atmosphere of apparent incoming life-bearing particles from space. In our view the totality of the multifactorial data and critical analyses assembled by Fred Hoyle, Chandra Wickramasinghe and their many colleagues since the 1960s leads to a very plausible conclusion – life may have been seeded here on Earth by life-bearing comets as soon as conditions on Earth allowed it to flourish (about or just before 4.1 Billion years ago); and living organisms such as space-resistant and space-hardy bacteria, viruses, more complex eukaryotic cells, fertilised ova and seeds have been continuously delivered ever since to Earth so being one important driver of further terrestrial evolution which has resulted in considerable genetic diversity and which has led to the emergence of mankind.

Russia says its ‘doomsday plane’ can now communicate with its deep sea nuclear submarines

Posted by in categories: existential risks, military

The test strengthens Russia’s nuclear command and control systems amid rising tensions with the West.

Russian defense officials are claiming a successful test of the Ilyushin Il-80 deep-sea communication system, allowing the Russian ‘Doomsday’ plane to communicate with deep-sea nuclear submarines in the event of a nuclear war.

According to the Russian state-owned news agency RIA Novosti, the Il-80 ‘Flying Kremlin’ successfully communicated with Russian nuclear submarines located deep underwater using ultra-long wave signals, enabling the Russian President to communicate and coordinate Russian military activity in the event of nuclear conflict.

Russia, U.S. to hold first talks under nuclear treaty since Ukraine war —State Dept

Posted by in categories: cybercrime/malcode, existential risks, geopolitics, military, nuclear energy, space travel, treaties

WASHINGTON, Nov 8 (Reuters) — The United States and Russia are expected to meet soon and discuss resuming inspections under the New START nuclear arms reduction treaty that have been paused since before Russia’s invasion of Ukraine, U.S. State Department spokesperson Ned Price said on Tuesday.

Speaking at a daily press briefing, Price said the bilateral consultative commission (BCC), the mechanism for implementation of the last remaining arms control agreement between the world’s two largest nuclear powers, will meet “in the near future.”

Russia in August suspended cooperation with inspections under the treaty, blaming travel restrictions imposed by Washington and its allies over Moscow’s February invasion of Ukraine, but said it was still committed to complying with the provisions of the treaty.
