That will disappoint SETI searchers and explain the so-called Fermi Paradox—the surprise expressed by physicist Enrico Fermi over the absence of any signs for the existence of other intelligent civilizations in the Milky Way.

We cannot assess whether the Fermi paradox signifies their absence or simply their preference.

The Fermi bubbles, and now the eROSITA bubbles, suggest that the main difference may simply be the passage of time.

Then in 2010, the Fermi space telescope caught the faint gamma-ray glow of two humungous lobes, each extending roughly 20,000 light-years from the galaxy’s center.

What that can tell us is how, over time, the energy output from the Fermi bubbles has changed.

It was, we were told, Fermi's atom-splitting feat in Chicago replicated at a scale of 200 million.

But at that point the Marchesa Fermi, having discovered a small bell on the mantel-shelf, began ringing it, to obtain silence.

As a matter of fact, the way out of the difficulty had been indicated soon after Fermi's original announcement.

Near Fermi they fell in with the enemy, about three thousand.
