Ask Ethan: Does the CMB really "prove" the Big Bang?

The CMB is considered strong evidence for the Big Bang theory, despite contrarian views that challenge its cosmological origin.

Arno Penzias obituary

Arno Penzias discovered cosmic microwave background, revolutionizing cosmology and challenging prevailing theories.

The Steady-State Universe: A viable alternative to the Big Bang?

The Big Bang theory remains uncontested due to its successful predictive power compared to alternative theories that fail to align with observational data.

Why you have always said your age incorrectly, according to astrophysicists

Our bodies are composed of atoms, with hydrogen being the most abundant and oldest element.
Hydrogen atoms in our bodies have been around since shortly after the Big Bang, making them older than our planet.

Ask Ethan: Why is the Big Bang shown as a tube?

The Big Bang represents a fundamental expansion of the Universe, distancing itself from misconceptions like explosions or singular points of origin.

What the "background noise of the universe" tells us about spacetime's origins

The Big Bang is not a specific moment but a period of time, as explained by scientists discussing the cosmic microwave background.

Arno Penzias, co-discoverer of the Big Bang's afterglow, dies at age 90

Arno Penzias, co-discoverer of the cosmic microwave background radiation, has died at age 90.
Penzias and Wilson's discovery of the cosmic microwave background radiation provided crucial evidence for the Big Bang theory.
