A study published this week in an astronomical journal suggests our universe could be 26.7 billion years old, or about twice as old as we thought.

Galaxy colonization simulations I’ve seen suggest colonization speed is exponential, so even a billion years added to the age of the universe should dramatically change things.
I think, if I recall, there was a study done recently that suggested we shouldn’t be too surprised if we have not seen aliens yet but probably soon, in the next 1000 years. But I can’t find the study - had 3D graphic of bubbles expanding outward and meeting.
Sounds like Robin Hansons “Grabby Aliens” theory?
That’s exactly it, thx.
