By the way, isn't it possible that Hantavirus mutated to spread much more easily between humans, but its long incubation period makes that hard to detect?

This is probably true for every scientist.

One of the most beautiful things about studying cosmology is that, within a human lifetime, we will have a different model accepted as the paradigm (one very different from today's), be part of a paradigm shift, and remember that everyone in our childhood had a much different story of the universe.

I have an unpopular opinion: People over the age of 50 should be banned from politics and government. Just as we ban under 18s.

We did a perfect hike to Preikestolen as N Pact School participants. Particle physics, cosmology, and Norwegian fjords intersected in space-time.

Unusual advantage of being from ‘the Middle East’: you are more likely to be the only author publishing with your last name (as in my case)😆

The last 3 years have been the hottest in around 125,000 years.
CO2 levels are their highest in MILLIONS of years.
But most people have no idea this is happening, let alone what it means for our kids’ futures.
Our politics & media have failed our children. We should be furious.
