Redshift Quantization
Back in year 2000, Halton Arp held this lecture on his career as an astronomer, and his findings related to the redshift of Quasars. Of the many things he discovered
The Significance of Dimorphos’ Tail
The short answer to why Dimorphos now has a 10,000 km long tail, some two weeks after NASA intentionally slammed a space probe into it
Dimorphos now has a 10,000 km Long Tail
Here’s an article by National Geographic that sheds more light on the DART probe and its impact on Dimorphos orbit around Didymos.
DART Probe has Changed Dimorphos’ Orbit
The NASA DART probe that hit the asteroid Dimorphos on September 27 has shortened Dimorphos’ orbit around its
DART Probe’s Impact Crater on Dimorphos
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
The Tetraneutron
The tetraneutron is a hypothetical stable cluster of four neutrons. However, such clusters are not supported by current models of nuclear forces, so recent news of its
Dipole 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 claims that satellite orbits verify Einstein’s formulas for time dilation because the exact time and position of satellites are continuously adjusted. Their article makes it
Time Dilation Due to Gravity
According to general relativity, clocks slow down in the presence of massive bodies. This is known as time dilation due to gravity. The effect of gravity is in other
