The Sun Is Weirder Than You Think
8 oktober 2026 · 18 min
If you dove into the sun, the first layer you’d hit is hot enough to make diamonds BOIL. Right now we’re in a golden age of new solar science. For the first time, we’re getting close-up pictures of the Sun like we’ve never seen. Sending probes into its atmosphere. And revealing secrets about our star we never thought possible… Trust me, after this video, you’ll never look up at the sun the same way. So let me take you on a journey… INTO THE SUN. Lees meer

This phenomenon only happens in Hawaii . . . and Cuba & Nigeria & Indonesia & Peru & Sudan & Laos &…
22 september 2026 · 4 min
There are only certain parts of the year and certain times of day when you can experience the subsolar point or Lahaina noon. There appears to be no shadow because the sun is directly overhead. This phenomenon happens twice a year for latitudes between the tropic of cancer and the tropic of capricorn at solar noon, when the sun is highest in the sky. But you have to be in the right place at the right time with no clouds! The photos and clips in this video were taken by my mom, Cathy, and friend Noel Liddell in Wailua, Po’ipu and Lawai, HI on July 11th (one day before exact Lahaina noon) and July 12th. Lees meer

Gravitational Waves Discovered for the First Time!
18 september 2026 · 5 min
In the press conference heard round the world, they showed the tell-tale waveforms indicating that huge event in which two black holes merged 1.3 billion lightyears away, had created waves that passed by the LIGO detectors and were finally heard. Einstein predicted the existence of these waves in his 1915 theory of general relativity. But it took a long time for us to come up with the technology to detect them. For one, we had to invent lasers! This video discusses why this discovery is important, what it means for astronomy, and what’s next. If you can’t tell, I’m very excited. Lees meer

How science explains monster waves
18 september 2026 · 6 min
Rogue waves - enormous, spontaneous surface waves in the open ocean - were once the tall tales of sailors. They are waves that reach 2-3x taller than the largest average waves in the area, reaching heights of 75 – 100ft. With the help of a ESA satellite survey, the scientific community now accepts they happen frequently. What causes rogue waves? Lees meer
