Universe is 13.8 billion years old, scientists confirm
2020-07-16
“The science is settled... until it’s unsettled again.”
[USATODAY] The universe is about 13.8 billion years old, according to new research recently published by an international team of astrophysicists.While this estimate of the age of the universe had been known before, in recent years, other scientific measurements had suggested instead that the universe may be hundreds of millions of years younger than this.

The scientists studied an image of the oldest light in the universe to confirm its age of 13.8 billion years.

This light, the "afterglow" of the Big Bang, is known as the cosmic microwave background and marks a time 380,000 years after the universe’s birth when protons and electrons joined to form the first atoms.

#7  Not .7?

Mother Earth is sensitive about such things.

#6  Nonsense. Pelosi & RBG are both at least twice that old.

Can someone explain the geometry to me? That 'light' left the point of origin 13.8 billion years ago at the speed of light. All the matter that makes up the universe, that has includes us, hasn't been traveling at the speed of light from the same location. Now we look 'back' and see this afterglow. Somehow the speed, angles, and present location don't add up. Asking for a friend.

...Took 'em long enough.
