Study challenges cosmological principle with evidence of large-scale galactic filaments
By

Summary
A new study published in Nature challenges the cosmological principle — the assumption that the universe is smooth and uniform on large scales — by presenting evidence that galaxies align in enormous filamentary structures even at scales where the cosmos should appear homogeneous. If confirmed, this "stringy" structure could undermine the standard model of cosmology (Lambda-CDM), which relies on the principle of cosmic sameness. The controversial claim has significant implications for our understanding of the universe's large-scale structure.

· 3 pulledLike a vast bowl of spaghetti, the universe may be stringy on length scales far larger than cosmologists have long assumed.
In a study published today in Nature, two researchers argue galaxies align in enormous filaments even on scales where the cosmos should appear smooth and uniform.
If correct, the controversial claim challenges the principle of cosmological sameness on which the prevailing theory rests.
