DENVER—The US Air Force's new Sentinel intercontinental ballistic missile is on track for its first test flight next year, military officials reaffirmed this week.

But no one is ready to say when hundreds of new missile silos, dug from the windswept Great Plains, will be finished, how much they cost, or, for that matter, how many nuclear warheads each Sentinel missile could actually carry.

The LGM-35A Sentinel will replace the Air Force's Minuteman III fleet, in service since 1970, with the first of the new missiles due to become operational in the early 2030s. But it will take longer than that to build and activate the full complement of Sentinel missiles and the 450 hardened underground silos to house them.

Netflix has dropped out of the bidding war for Warner Bros. Discovery (WBD), making Paramount Skydance the expected owner of WBD. A Paramount-WBD merger remains subject to regulatory approval, but it’s likely that we will see a Paramount-Skydance-Warner-Bros.-Discovery media giant.

Such a conglomerate would unite two legacy media companies that have struggled with profitability for years and have strongly invested in streaming and cable.

With Paramount inching closer to WBD ownership, let’s look at what the union implies for streaming and cable.

Despite the headline, this isn't really a story about superconductivity—at least not the superconductivity that people care about, the stuff that doesn't require exotic refrigeration to work. Instead, it's a story about how superconductivity can be used as a test of some of the weirder consequences of quantum mechanics, one that involves non-existent particles of light that still act like they exist.

Researchers have found a way to get these virtual photons to influence the behavior of a superconductor, ultimately making it worse. That may in the end tell us something useful about superconductivity, but it'll probably take a little while.

Virtual reality

The story starts with quantum field theory, which is incredibly complex, but the simplified version is that even empty space is filled with fields that could govern the interactions of any quantum objects in or near that space. You can think of different particles as energetic excitements of these fields—so a photon is simply an energetic state of the quantum field.
