This is the crux. Optimization of supply chains to eliminate inventory makes them frail. Or, to quote Wirth:

Premature optimization is the root of all evil.

The last of the US federal helium reserve - including land and equipment - was sold in 2024.

Is joke of course. Was angling for the same joke.

3He is normal helium atom with an extra neutron, hoped to be used in some forms of fusion. It's not considered radioactive. Emitted by the sun it's trapped in lunar rock possibly at concentrations of up to 50 parts per billion but more likely 5-10ppb. The utility of extracting it from the Moon is hotly debated. On Earth isolating it from normal helium involves the same sort of centrifuge used to isolate isotopes of uranium, radium, hydrogen but there is far less of it than in lunar soil.

This is not actually the case in the subject at hand. It's all normal helium. When cooled enough all other gases will precipitate out as they freeze - including Hydrogen - leaving only helium as a gas and so easily isolated. That's actually why it's valuable since it's the only gas that will boil off at temperatures so low that the conductors immersed in the fluid will superconduct supporting the currents necessary for the intense electromagnets used in imaging and such. /Explaining nerd jokes since 1983

Other similar stars were here in this galaxy for 8 billion years before the Sun even formed - twice as long as then to now. Inception of life as we know it on Earth was effectively instant upon planet formation, which was contemporaneous with solar ignition.

There are no FTL speeds. No exceptions.

The Milky Way is home to about a billion civilizations more advanced than us. We are late to the party.

Fortunately space is really big, or we would be them.

This is nonsense. They skim from the first subcontractor to maximize proceeds from the top line while maintaining deniability. The prime gets a slice and then there's a sub-sub tree leaking all the way that eventually converges at a boiler room in India where the actual work is performed for $500.

Thank goodness it doesn't run AI. Was pricing small TVs to use as an auxiliary monitor today. It's hard to imagine how they make this work financially.

Got his. That was the day to walk away.

It only takes 45 nucleotides to make self-replicating RNA.

The Universe is made of soup. Soup clouds form soup stars and planets where it rains soup from space forever.

A statistically unlikely number of times.

Going to Mars personally is no longer in his future for national security reasons.

Only a fool would want to.
