So if there are other continents beyond the ice wall according to memes then why can't we still not explore and prove it?

i heard access to civilians to Antarctica is permitted in one tourist trap site, just book a ticket and done.

so i was wondering why not just book a ticket, get to antarctica, the at night sneak out and keep walking in a straight life with a compass till you reach the "ice wall". Then photograph it for evidence for the whole world or even better climb it and cross over to other continents that aren't on any maps known to this world.
Anyone up for it?
What do you think you'd find in other continents?
