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.
You nailed a thing I think many miss. Our signals will be static soon, and I don’t care what kind of magical tech aliens have. Static is static, truly random noise.
And as a civilization progresses, less and less need for EMF broadcast. Think fiber vs. AM radio. Maybe we’ll hit a tech point where, for whatever reason, we broadcast more EMF, dunno.
