okey, I think the problem with the next part is us lol
"one of my friends always lies" right?
Then:
"I visited a rocky planet at latitude 34 near binary pulsars" - then we went "well, there are no binary pulsars, so he must be lying about that part, so lets look for a rocky planet..."
No. The first person said ALWAYS lies. There is no rocky/icy planet near lat/long 34/xx near anywhere. The whole thing is a lie. We can't just pick and choose bits from his sentence. the whole thing is a lie
unless they were telling the truth, and the other person is lying.
well if hes the liar why not think of whatever he is telling us is the opposite?
