Ask Ethan: Could dark matter be "normal stuff" we can't see?The Universe is made up of 5% normal matter and 95% dark matter and dark energy, which remain largely undetected.
Does dark matter interact non-gravitationally at all?Dark matter and dark energy are essential components to explain discrepancies between observations and traditional cosmic models.
Our Universe has more galaxies than Carl Sagan ever imaginedThe Universe may contain between 6 trillion to 20 trillion galaxies, vastly exceeding previous estimates.
Ask Ethan: Why doesn't dark matter collapse due to gravity?Dark matter constitutes 27% of the universe's mass but doesn't collapse like normal matter due to basic principles of gravitational interactions.
Dark matter search: Are scientists looking in the wrong direction?Scientists have only indirect evidence for dark matter, despite its expected prevalence in the Universe.

Do We Live in a Special Part of the Universe?The universe's structure is homogeneous, emphasizing humanity's lack of cosmic significance.
The CMB: the most important discovery in cosmic historyThe cosmic microwave background (CMB) is a crucial discovery that shaped our understanding of the early Universe and validated the Big Bang theory.
Something Is Wrong with Dark Energy, Physicists SayNew research suggests dark energy has weakened over time, challenging previous assumptions of its constancy and prompting new insights into cosmic evolution.
This Ancient "Rebel" Galaxy Closely Mirroring the Milky Way Has Astronomers Freaked OutThe discovery of REBELS-25 challenges existing theories on galaxy formation and evolution, suggesting early galaxies were more similar to the Milky Way than previously believed.
Why Is the Night Sky Dark? You Can Thank the Big BangThe darkness of the night sky reveals profound insights about the universe and challenges conventional beliefs about its structure.
We've all been there! Black hole takes a 'nap' after overeatingA newly discovered black hole, 400 million times the Sun's mass, shows periods of hyperactivity followed by long dormancy, challenging black hole growth models.
