Ep. 598: How You Could Overturn Cosmology

You’ve probably heard of dark matter and dark energy, but maybe you don’t fully understand what they are. Or maybe the idea itself just rubs you the wrong way and you’d like to know why scientists think they can just make stuff up like this. So you’d like to overturn cosmology? Here’s all you need to do.

Ep. 592: Gamma-Ray Bursts (Updated)

Some of the most powerful explosions in the Universe are gamma ray bursts, capable of blasting a beam of death halfway across the galaxy. In just the last few years, astronomers have discovered a tremendous amount about these blasts, and what’s actually causing them. The answer, of course, is that it’s more complicated than we thought.

Ep. 591: Space Junk

Remember the good old days, where there were only a few thousand living and dead satellites? Those days are long over. We’re now entering an era where there will be tens of thousands of satellites, not to mention the spent rocket boosters and other space junk. What kind of a risk do we face and what can be done about it?

Ep. 590: Lunar Hazards: Dust, Radiation, and More

2024 can’t come soon enough. You know, that’s the year when humans will set foot on the Moon again. Don’t you roll your eyes. That’s the plan. Well, unless the plan changes. But my point is, explorers going to the Moon will need to be concerned about all kinds of hazards, like dust, radiation and gigantic moon worms.
