Prior to watching a:c i was thinking that david caused the detour to Planet 4.
Even though it seems a stretch that David caused the Neutrino burst i think it is possible in some way.
I will start by saying that when Prometheus embarked, the Covenant mission may of been in the final planning stages, which gave David knowledge of its existence.
So if David knew there was a planned mission which would be flying close to Planet 4. (it took 2 weeks to get to P4 from where the Covenant was when the Neutrino burst hit.)
So David wants hosts and the Covenant is his target.
Whether David was in touch with WY or not i believe either way he knew about Covenant.
Im not a scientist this is a loose theory:
So David may of caused an event which would trigger a Neutrino Burst or whatever it was. He may of planned it, his superior brain may of predicted exactly where Covenant would be in space, then triggered an event which may of been something else but it did the same as a Neutrino burst would. So MUTHUR was fooled or on David / WY secret mission and so MUTHUR reported it as something it may not of been, but what would cause the damage it did.
This triggers the Crew revival which leads to the signal.
Perhaps the plan needed to be super intricate to fool the senior crew members into landing.
David knew the event would cost lives so the crew wouldnt be keen on going back in the pods, this would later, lean the crew towards a closer world. Where as normally this would be ignored.
The signal: Wasnt picked up because of communications buffers, so David knew this and aimed the signal precisely where Tennessee would recieve it.
You never know, David may of had Plan B,C,D etc.. If Tennessee doesnt recieve the signal, then Davids plan always had another piece, eventually he would succeed.
So I think it was an elaborate plan, whether the Burst was that and it is an event you cant predict, either way i dont believe they got to Planet 4 by chance.
David somehow done it.
Also when David arrives and they get talking, his remarks could be seen as though he knew without saying.
2000 colonists on board
David: "Really, so many good souls"
