Hawking radiation is a theoretical type of thermal electromagnetic radiation that astrophysicists predict is emitted by quantum singularities (black holes). The theory was first posited by Professor Stephen Hawking and physicist Jacob Bekenstein who theorized that whenever stellar matter enters the event horizon (the boundary of a singularity where its gravitational pull becomes so strong nothing can escape, not even light) its interaction with the singularity's quantum/gravitational field would produce a unique type of radiation. Figuring out how to detect Hawking radiation would help locate singularities far more accurately than current methods; however as of 2018 no confirmed cases of Hawking radiation have been found out in interstellar space.

Will is sitting under the "light tower", plugging things in, when John walks up to him:
John: Hey, you might want to run those in parallel. That way if one of the lamps shorts, the others won't go out as well.
Will: Like Christmas tree lights?
John: Yeah. Yeah, exactly.
1) If any light wired in parallel with others "shorts" (becomes a short circuit from one of its connections to the other), all the other lights will go out too because the over-current protector (circuit breaker or fuse) will turn off the power supply, or there will be a fire. He meant to say "if one of the lamps blows" (becomes an open circuit).
2) The type of Christmas tree lights that they are referring to are the old, cheap ones that are all wired in series on a loop of single-conductor from one terminal of the plug to the other. If one of those becomes a short circuit, it will of course not light up, but all the others will (and in fact will each be operating with a higher voltage drop and be brighter, possibly also malfunctioning). What usually happens to light bulbs, though, is that the filament breaks and it becomes an open circuit, in which case none will light up. Neither of the characters is likely to have ever encountered that type of Xmas light string in their past life, in 2049, since they haven't been popular or made that way for decades as of 2019.
