The current theoretical model for the composition of the universe is that it's made of 'normal matter,' 'dark energy' and 'dark matter.' A new uOttawa study challenges this. #science #physics #astronomy #astrophysics https://www.sciencedaily.com/releases/2024/03/240315160911.htm

Researchers have developed a solid electrolyte for transporting hydride ions at room temperature. This will reduce their complexity and cost, which is essential for advancing towards a practical hydrogen-based energy economy. https://www.sciencedaily.com/releases/2023/12/231222145439.htm #science #physics #greenenergy #hydrogen

Wow. That’s a shitty move.

“Say you search for ‘children’s clothing.’ Google converts it, without your knowledge, to a search for ‘NIKOLAI-brand kidswear,’ making a behind-the-scenes substitution of your actual query with a different query that just happens to generate more money for the company.”

Ka-ching!

When I was a kid in the 80s and 90s, I watched Star Trek: The Next Generation. I soaked up the vibes of a high-tech, utopian future. I internalized the trajectory we were on was good, that we had reached the End of History. There might be a few bumps on the road, but the direction was inevitable and the destination was inexorable.

It turns out that the fastest a human being has ever traveled was 39,897 kilometers per hour. That was the crew of the Apollo 10 mission returning to earth. That happened on 26 May, 1969.

Fifty-four years ago. We peaked more than half a century ago.

Research confirms fracking causes slow, small earthquakes, whose origin was previously a mystery. The tremors are produced by the same processes that could create large, damaging earthquakes. #science #fracking #environmental #earthquakes https://www.sciencedaily.com/releases/2023/08/230810110345.htm
