The laws of physics governing our universe have posed countless questions for scientists. But what if there were a simpler way to view the cosmos? An approach that accounts for the speed of light, time dilation, redshift, dark energy, and the expansion of the universe? My brother, Jon, has proposed just such a hypothesis—a theory of everything that could explain all of this and more. The biggest question is: is he right?

#Astrum #Universe #TheoryOfEverything
Alex McColgan explores a geometric model of the universe developed by John to explain phenomena such as time dilation, length contraction, and redshift. By visualizing spacetime as a four-dimensional structure, this perspective aims to resolve long-standing scientific mysteries without relying on conventional assumptions regarding dark energy or the speed of light.
