How To Become An Astronaut

With the launch of the Crew Dragon, we have entered a new era of space travel, including multiple rides to space. This will grow the need for astronauts. Want to be one of them? Here’s how.

Jupiter’s Great Red Spot Is Shrinking (Also, Jupiter Is Insane)

Jupiter’s Great Red Spot has been the biggest storm in the solar system for centuries. But lately, it seems to be shrinking… and nobody’s sure why.

So this video was supposed to just be about the Great Red Spot but honestly the more I looked into Jupiter, the more I was struck by how insane the planet is. So it kinda became about that.

Could Space-Based Solar Save The World?

Solar power is on the rise, and that’s a good thing. But solar power has one major drawback – it can’t make energy at night, which is literally half the time.

But there is a place where you have constant sun, 24 hours a day, with no cloud cover, and get twice as much energy – outer space.

Could giant solar panels in space be the key to unlimited energy?

Experiments like the double slit experiment have spawned multiple interpretations of quantum physics, including the Copenhagen interpretation and Pilot Wave Theory. But the Many Worlds Hypothesis might be the most mind-blowing of all.

The most popular interpretation of quantum mechanics over the past hundred years was developed by Niels Bohr and Werner Heisenberg in Copenhagen, around 1925. This was fittingly named the Copenhagen Interpretation.

Louis de Broglie [de Broy] came up with the Pilot Wave Interpretation of Quantum Mechanics at about the same time, which I’ve also covered.

Both of these interpretations share the belief that the measured path of a particle is the only real path. The other paths are mere possibilities.

About 30 years later, a slightly drunk Princeton student disagreed. While sipping sherry, or so the story goes, Hugh Everett III started asking, what if all the paths do exist, but are just taken in different realities?

Everett’s ideas were… not well received to say the least. At the time, Niels Bohr was then alive and active in scientific circles. He had a reputation for shutting down any physicist who dared challenge the Copenhagen Interpretation.

And that was where the idea stayed, relegated to the dustbin of history, for the next 2 decades, before it got rediscovered by Bryce DeWitt.

He was the acting editor at Reviews of Modern Physics in 1973 when he ran across the paper and was stunned that nothing ever came of this idea.

Since the 1970s, the Many Worlds Interpretation has gone from being fringe science to an idea mainstream physicists can get behind.

Stephen Hawking was a fan, as was Richard Feynman…though to hear physicists tell it, Feynman was a fan of literally EVERYTHING.

One prominent proponent of Many Worlds working today is David Deutsch, who is a quantum computer pioneer whose cool factor went through the roof when he was mentioned in Avengers: Endgame.

The Black Hole Photo: Mystery Solved

Last week, the Event Horizon Telescope released their first images ever taken of a black hole, specifically the supermassive black hole at the center of galaxy M87. I thought this would be a good time to look back at how we’ve visualized Black Holes over the years and what we can learn from them.
