Black holes the size of an atom that contain the mass of an asteroid may fly through the inner solar system about once a decade, scientists say.

Theoretically created just after the big bang, these examples of so-called primordial black holes could explain the missing dark matter thought to dominate our universe.

And if they sneak by the moon or Mars, scientists should be able to detect them, a new study shows.

Such black holes could have easily arisen right after the universe was born, when space is thought to have expanded hugely in a fraction of a second.

During this expansion, tiny quantum fluctuations in the density of space would have grown larger,
and some spots may have become so dense that they collapsed into black holes scattered throughout the cosmos.

If dark matter is fully explained by such black holes, their most likely mass, according to some theories, would range from 10 to the 17, or up to 10 to the 23 grams
—about that of a large asteroid.

If primordial black holes are responsible for dark matter,
they probably zip through the solar system about every 10 years,
a new study found.

If one of these black holes comes near a planet or large moon, it should push the body off course enough to be measurable by current instruments.

“As it passes by, the planet starts to wobble,” says Sarah R. Geller, a theoretical physicist now at the University of California, Santa Cruz, and co-author of the study, which was published on September 17 in Physical Review D.*

“The wobble will grow over a few years but eventually it will damp out and go back to zero.”

I read that the official Mastodon instance of the Swiss government will be closing down.

They say there are few active users, low engagement, and minimal interaction, which seems quite plausible. Additionally, they claim that "on platforms like X or Instagram, the Federal Council and the Federal Administration have many more followers." I believe that too, of course.

However, I do not agree with their decision. I think a government shouldn’t be overly concerned about follower counts and interactions, but rather about providing free, autonomous communication that is independent of third-party companies. In my view, a government shouldn’t operate like a business focused on "numbers."

Still, I appreciate their experiment - many governments, like the Italian one, haven’t even tried.

Regarding costs and management effort: an instance with 5 users and 3,500 followers (numbers provided by them) can run on a VPS for €3 a month and doesn't require heavy moderation. The cost for them is nearly zero. Yet, the freedom of information and discussion, especially for a Neutral Country, should always be a priority.

I believe that maintaining control over one’s information channels is crucial, especially in today's world. But, I fear that decision-makers only consider the numbers, which often favor the flashiest - but worse - solutions.

Encouraging citizens to use closed platforms is, in my opinion, a wrong choice.

Thanks to the Swiss government for at least giving it a shot.
