Helio replied to the thread Sub-Earth' exoplanet discovered around the closest solo star to us.Curious that it took this long to find it given it's a close neighbor. But it has a solar equivalent distance of 0.41, so it gets a...

Helio reacted to AboveAndBeyond's post in the thread We are close:' SETI astrobiologist Nathalie Cabrol on the search for life with Like.
I don't understand how you get "close". Either you've got an ironclad SETI detection or you don't.

Helio replied to the thread How dark energy could relieve 'Hubble tension' and galaxy headaches.Agreed. Besides, what's special at about 2k years after t=0? Almost any extra DE imagined could be assumed prior to Recombination...
