Elon Musk denies blocking Starlink over Crimea due to fear of nuclear war

Posted by in categories: Elon Musk, existential risks, internet, satellites

“All bets are off if the nukes start flying,” Musk recently tweeted.

Elon Musk reportedly rejected a request from within Ukraine to extend SpaceX’s Starlink satellite internet coverage to Crimea, according to a newsletter from political analyst Ian Bremmer.

However, Musk has taken to Twitter after those reports were published and has cast doubt on their veracity by claiming that “nobody should trust Bremmer”.

Ancient Martian life may have created the conditions for its own extinction

Posted by in categories: biological, existential risks


The study was published in Nature Astronomy, and it details how simple microbes that fed on hydrogen and excreted methane were likely abundant on Mars roughly 3.7 billion years ago. This was at approximately the same time that the earliest life was forming in Earth’s oceans.

How likely is it that we live in a simulation? Are virtual worlds real?

In this first episode of the 2nd Series we delve into the fascinating topic of virtual reality simulations and the extraordinary possibility that our universe is itself a simulation. For thousands of years some mystical traditions have maintained that the physical world and our separated ‘selves’ are an illusion, and now, only with the development of our own computer simulations and virtual worlds have scientists and philosophers begun to assess the statistical probabilities that our shared reality could in fact be some kind of representation rather than a physical place.
As we become more open to these possibilities, other difficult questions start to come into focus. How can we create a common language to talk about matter and energy, that bridges the simulated and simulating worlds. Who could have created such a simulation? Could it be an artificial intelligence rather than a biological or conscious being? Do we have ethical obligations to the virtual beings we interact with in our virtual worlds and to what extent are those beings and worlds ‘real’? The list is long and mind bending.

Scientists just issued a shockingly bleak ‘warning to humanity’

Posted by in categories: economics, existential risks, food

Scientists say that Earth’s trees are facing an unprecedented level of extinction and humanity should be worried. The state of our world’s trees has been an ongoing issue for decades now. But, that issue seems to be getting worse, and now we’re facing a massive extinction level issue that could threaten entire ecosystems.

Trees play an important role in the various ecosystems that cover our planet. Last year, a team of researchers released a paper titled State of the World’s Trees, which looked at how the loss of some tree species has affected entire ecosystems. Now, that same team of researchers has issued a warning as the ongoing issue with Earth’s trees has become even direr.

The research is backed by 45 additional scientists from over 20 different countries and outlines the many impacts that losing any of these tree species could have on the world. It isn’t just the local ecosystems that would be affected by these losses, either. The researchers say these losses will affect our livelihoods, economies, and food.

A Physicist Claims He’s Figured Out Why We Haven’t Met Aliens Yet, And It’s Pretty Worrying

Posted by in categories: alien life, existential risks

There must be some intelligent life out there or else it’s a terrible waste of real-estate.

The question “where is everyone?” is the crux of the Fermi Paradox. If life on Earth is not particularly special and unique, where are all the alien civilizations? Many explanations have been proposed to explain why we seem to be alone in the vast universe. None have been 100 percent convincing, and people continue to puzzle over a solution.

Russian physicist Alexander Berezin, from the National Research University of Electronic Technology (MIET), has another idea. He calls it the “First in, last out” solution of the Fermi Paradox. He suggests that once a civilization reaches the capabilities of spreading across the stars, it will inevitably wipe out all other civilizations.
