Is the Universe 13.8 or 26.7 billion years old?
Our universe is actually 27 billion years old, almost double the current age estimate
According to the “Standard Model” of cosmology, the Universe is 68% dark energy, 27% dark matter, 5% normal matter, and is 13.8 billion years old: as measured since the hot Big Bang.
Recent observations from the James Webb Space Telescope (JWST), however, have found numerous galaxies that appear early, but look surprisingly grown-up. A new theory claims to solve this “early, grown-up galaxies” problem by changing the age of the Universe to 26.7 billion years old.
I guess finding a galaxy that is older than 13.8 billion years would lend credence to the hypothesis.
But yeah, there’s definitely something wrong with cosmology.
Here’s a good video about the topic from an astrophysicist. https://youtu.be/aBYgck1zAgQ
Dr. Becky is the best!
She’s always at the top of my science-videos playlist when she has a new video out.
Same. I jump on her vids right away unless, maybe, an acollierastro video was also released.
I seem to recall hearing recently about results that seemed to indicate that a certain galaxy is older than we’d expect.
Well they found a galaxy at 390 million years after the big bang, that according to current understanding should be billions of years old. That should do, I think?
Great YouTube channel thanks for sharing!
