Summary:
The few thousand galaxies closest to us move in a vast 'bubble' that is 250 million light years in diameter, where the average density of matter is half as large as for the rest of the universe. This is the hypothesis put forward by a theoretical physicist to solve a conundrum that has been splitting the scientific community for a decade: at what speed is the universe expanding?

The earth, solar system, entire Milky Way and the few thousand galaxies closest to us move in a vast "bubble" that is 250 million light years in diameter, where the average density of matter is half as large as for the rest of the universe. This is the hypothesis put forward by a theoretical physicist from the University of Geneva (UNIGE) to solve a conundrum that has been splitting the scientific community for a decade: at what speed is the universe expanding? Until now, at least two independent calculation methods have arrived at two values that are different by about 10% with a deviation that is statistically irreconcilable. This new approach, which is set out in the journal Physics Letters B, erases this divergence without making use of any "new physics."

i'll just put this here.

No way this planet makes it "billions of years from now". At least not with life as we know it.

Maybe if the earth crashes into the sun, we can just become sun people.

If it takes bilions of years, evolution has time to act.

Archaea can survive extreme environments. Maybe humans will evolve closer and closer to archaea until the heat is just too much.
