The Universe May Not Be Accelerating After All-And It Could Mean Dark Energy Never Existed
New research suggests that the universe may be anisotropic, challenging the long-held assumption that it is expanding uniformly in all directions. This finding could potentially invalidate the existence of dark energy, which has been used to explain the universe's acceleration.
Why it matters
If confirmed, this discovery would force a fundamental rewrite of modern cosmological models and our understanding of the universe's origins.

Cosmologists have long assumed that our expanding universe is isotropic, meaning it looks the same when viewed from any angle.
Researchers found that there were errors in some of these previous theories when they examined observations of Type Ia supernovae.
Because of these errors, the researchers determined that the universe is probably anisotropic, meaning that everything does not accelerate at the same rate from every direction.
