...Scientists have believed dark energy was a "cosmological constant," but it is actually changing over time in unexpected ways...current data shows that, at the beginning of the universe, dark energy was very strong. But it has weakened with time and will continue to do so...The new research builds on data released from DESI in April 2024 that found signs that dark energy was changing. DESI has been surveying the universe for four years and an analysis of five years' worth of data is next for its research

Who knows?

Our edge might be trillions of years from the closest edge and entropy will make us "nothing" before we collide.

Tomorrow the overlap could happen, an entire different reality with maybe complete different physics and life could just suddenly overlap with our boundaey. If it was "new" it would fly thru ours, almost instantly. If it was "old" it could take billions of years to notice. It might start off a chain reaction where we annihilate each other, we might merge, or even just pass thru each other with zero effect on either.

Like, this is just one of a literal dumbfounding amount of things that we just have zero idea about.

We want to never know the answers, but some day we might just find out with zero warning.
