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.

A factor of 2 is not a big deal for the Drake equation
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.
