The sun orbits Sirius, and is currently close to the aphelion, the furthest the two stars get from one another (actually, roughly 2000 years has passed since the aphelion when Sirius also changed color

Light bent around objects like planets and suns, is just refraction from entering a new medium

The cosmological (CMB) red shift is caused by how as energy decreases, wavelength increases, E = h * c / λ, wavelength is inversely proportional to energy of wave.

CMB red shift is not related to the doppler effect, cosmological red shift is caused by how as energy decreases, wavelength increases, E = h * c / λ, wavelength is inversely proportional to energy of wave.

If gas giants are a natural next stage of terrestrial planets, then Mars would probably be next, and similar to the life cycle of stars, it would have contracted as it had consumed its primary fuel, from

The saying "you don't see the forest for the trees" points to that human cognition is biased to how and where it focuses its attention, what reference frame it is seeing the world through, and

The "flat earth" meme is a result of that dominant models are false, plate tectonics is a proto-science for expansion tectonics, Newtons law of universal gravity a proto-science for electricity,

Knowledge about the sun-Sirius system was lost, naturally, because Sirius stood out less as the distance to Sirius from our sun increased, and from having been quite large in the night sky close to the

Sirius, the biggest star in the night sky, used to be much closer 15,000 years ago at the perihelion of the sun-Sirius binary system, and reached the aphelion 2000 years ago, which also shifted its color

All magnets have a magnetic field, an area around a magnet where its magnetism affects other objects. Stronger magnets can generally attract magnetic materials from a farther distance than weaker magnets.

The Sirius system is a binary with our sun, and is a helical system as our sun, which means it travels through the galaxy like a spiral, with its planet spiralling (only one mapped so far, discovered in

As the sun orbits Sirius, the motion of Sirius on the night sky is not like the other stars, and in the 1800s, the unusual stellar parallax led to the idea that it could be the result of an "invisible

I could never wrap my head around the “coriolis force” then 6–7 years ago when I was learning about weather systems on Earth, and now I understand why: it is complete nonsense. The circular currents, that

As planetary magnetic fields reverse their polarity at times, the orientation of the Earths magnetic field at the time is not the way it has been oriented at all times. Mars magnetic field is currently

All magnets have a magnetic field, an area around a magnet where its magnetism affects other objects. Stronger magnets can generally attract magnetic materials from a farther distance than weaker magnets.

Gravity is a proto-science, to describe electromagnetic attraction When gravity was conceived in the 1600s, electricity had not yet lit up the world, and there was no reference frames for thinking in terms

As has been observed on at least Jupiter, Saturn and Earth, the atmosphere at the poles rotate in the opposite direction of the atmosphere, with aurora forming at the boundary of the rotating mass. This

In the outer shell of gas giants, hydrogen fuses to helium as in the core of younger planets. In the next shell in, helium fuses to carbon. Succeeding shells within fuse carbon, oxygen, neon, and silicon

I just realised why people have believed, since Newton in the 1600s, that the Earth "wobbles", as an explanation for the precession of the Zodiac. Since Jupiter is so large, it looks as it would
