This nova episode was a game changer for me. I always thought the Hadean era was devoid of life because of all the asteroid impacts. This episode indicates that the asteroids may have been essential to the creation of life. Comments?

For centuries the world, galaxy and universe are bigger than we believed possible. Now the observable universe is 92 BLY in diameter. Based on the lack of curvature, the total universe must be at least 400 TLY in diameter. So what we see is at most 1.13 e-9 vol % of the total. Mind blown.

Two local newspapers (Press Democrat and Argus Currier) have been bought by this hedge fund and will be dismantled. Darkness is coming to you too.

Interesting comment about the origin of the Epstein ring. Epstein has many emails and meetings with Russian handlers. The Russians provided many girls. Gathering compromising info on key people has been used by Russia for years. This would be a gold mine.

Catalyst researchers: Has anybody seen methanol decompose over silicon carbon diluent in a reactor. Temperatures were about 450°C and the balance of the gas was hydrogen and CO. I can’t find any reference to a reaction like this.

I had to take my dog to the vet and missed the rally. I watched FB rallies around the world but was dismayed by MAGA laughs and snide comments. We were busy at the rally but can now love the rallies. If you love a few FB will show others.

Neil deGrasse Tyson has a FB page but there is another hosted by Interstellar Inc. That is a Digital Content Creator’s site consistent with people who post. Most posts are benign and left leaning. Others are factually false. Anyone know if NDT approves this site?

A suggestion has been made that advanced AI should have a system that cares about humans - sort a maternal instinct. But I don’t trust a super intelligent agent to make decisions about what is in my best interest. Do you? Asimov wrote about this.
