NASA’s article on the successful crashing of a space probe into the asteroid Dimorphos mentions a follow up mission that will inspect
NASA’s DART Probe Hits Asteroid
The NASA DART probe that I wrote about a year ago has reached its destination. It has crashed into an asteroid in order to alter its orbit
Directional Gravity
Newton assumes in his work that gravity is a monopole acting with equal force in all directions, regardless of intervening matter. These assumptions are central to his shell theorem which
Satellite Orbits
Wikipedia's article on time dilation makes it sound like Einstein's equations are used to pre-calculate satellite orbits. However, there are too many unpredictable factors related to satellite orbits for this to be true. Unpredictable factors To mention but a few…
Two Bizarre Blobs Detected Deep Inside Earth
Studies of seismic data have revealed that Earth contains two large structures. One is located under the west coast of Africa. The other is located under the Pacific, at the opposite side from the African blob. Standard explanations There are two…
Thinking About Gravity
The theory of physics presented here came about as a result of some intriguing problems related to gravity. Puzzles and problems For one, the enormous size of many dinosaurs indicate that gravity was less strong in their time. On the…
Sahara Dust Storms
The weather forecast was for sunny weather and temperatures reaching 20C, but instead we got three days with clouds and max temperatures of 17C. This hadn’t
The Problem with the Growing Earth Model
Onar Åm is a Norwegian physicist with a sufficiently open mind to consider Earth expansion a valid alternative to conventional fixed size Earth plate tectonics. He was the one who first suggested this possibility to me, and therefore the person…
A Month in the Life of an Active Volcano
The La Palma volcano is in a constant state of flux. At the start of November it looked like this: La Palma Volcano on November 1, 2021 Its two main fissures were facing towards the camera. On November 30, those…
Volcanic Plumes and Ash Clouds
The La Palma volcano hasn’t changed much since I last wrote about it. It continues to belch out lava and volcanic ash. From up close it looks no different from a week ago
