Can you explain in layman’s terms what this might mean?

  It means they are trying to contact it using the most powerful antennas available. It hasn't phoned home yet.

  they established a lock and were sending data at 11kW to the lander.. maybe trying to do some kind of recovery...but no communication back from the lander

  It means they could hear the radio signal they were sending reflect off the probe, but the probe was like "Nah ain't talkin!

That singal strength is like barely above photonic noise

  I'm guessing it's a false positive from noise amplification instead.

I apologize for not reading ALL 500+ Comments (stopped halfway as the politics and history took over). This may have been mentioned. In some occasions when an event is being broadcast live, a 10-30-60 seconds delay is added to the signal "just in case". Is there any chance that the Probe crashed on the moon and India's gov/space agency cut the feed while YouTube, live TV, etc. was on this +60 seconds? I remember when the 3 of SpaceX rockets were doing the concurrent landing (2 at land, 1 at sea), the sea platform link had "a problem" and went down. Then miraculously once the situation was assessed another video surfaced from a nearby camera some time later and we saw that the rocket tilted and fell at sea. With that said I hope all (peace driven) space exploration efforts go well and we end up with a Star Trek TNG society in 300-400 years.

ISRO located the lander and got a thermal image from the orbiter https://timesofindia.indiatimes.com/india/chandrayaan-2-isro-gets-image-of-vikram-lander-communication-yet-to-be-established/articleshow/71033778.cms https://timesofindia.indiatimes.com/india/chandrayaan-2-isro...
