The Solar System Might Be Moving Faster Than Expected – Or There’s Something Off With The Universe
According to the standard model of cosmology, the universe should be the same everywhere and look the same in every direction. A little caveat on this last part is that it’s the same in every direction if the observer is not moving,
How fast and in which direction is our solar system moving through the universe? This seemingly simple question is one of the key tests of our cosmological understanding. A research team led by astrophysicist Lukas Böhme at Bielefeld University has now found new answers,

Solar storms can trigger auroras on Earth. This star’s explosion could destroy a planet’s atmosphere
Astronomers say they spotted signs of a giant explosion releasing from a star beyond our solar system, one powerful enough to destroy a planet’s atmosphere.

A "Very Old, Undisturbed Structure" May Have Been Discovered Beyond The Orbit Of Neptune, 43 AU From The Sun
"Similar to the asteroid belt, the Kuiper Belt is a region of leftovers from the solar system's early history. Like the asteroid belt, it has also been shaped by a giant planet, although it's more of a thick disk (like a donut) than a thin belt."
In 1949, famed mathematician and physicist John von Neumann delivered a series of addresses at the University of Illinois, where he introduced the concept of the "universal constructor." The theory was further detailed in the 1966 book,
Simulations reveal that Jupiter’s rapid growth disrupted the early solar system, creating rings where new planetesimals formed much later than expected. These late-forming bodies match the ages and chemistry of chondrite meteorites found on Earth.
New research suggests that Theia, the object whose collision with Earth is theorized to have caused the formation of the moon, came from closer to the sun.
Study from Bielefeld finds major departure from the standard model. How fast and in what direction is our solar system moving through space? This question, though simple in appearance, plays a central role in testing modern cosmological theories.
