Note sull'episodio
What do three feeding black holes packed into one ancient galaxy, an alien-signal search that covered millions of stars but almost none of the radio dial, a humpback whale song that changes with the dive, and a brain tumor treatment that works through the neck have in common?

And those mergers may explain why the earliest black holes grew so impossibly fast. A PhD researcher at the University of Manchester searched ALMA telescope data at radio frequencies almost no one has tried for ...
