From Penny Sarchet at New Scientist:
Rather than springing into existence just once in some chemically blessed primordial pond, life may have had many origins. It could have got going over and over again in many different forms for hundreds of thousands of years, only becoming what we see today when everything else was wiped out it in Earth’s first ever mass extinction. In its earliest days on the planet, life as we know it might not have been alone. More.
And it is not happening all around us now because …
Oh wait! That is a Boltzmann brain floating above the inkjet printer…
Is the Boltzmann brain a protected species? I better find out.
Note: One could subscribe to read the whole thing. One wishes NS (and many other publications) would charge (reasonably) to read the individual articles instead of assuming that one wishes to hear from them for the rest of one’s life about hundreds of topics.
