while browsing youtube, i've found http://www.youtube.com/watch?v=ZrTJLh1d2PU, which is basically a little over 3K blocks of TNT blowing up without lag or a server crash. he did this by upping the memory allowed to 9 GB of ram. i later found a clip where he detonated 10K blocks of TNT in a city. yet, i'm wondering...
CAN WE GO BIGGER?
is it possible with a strong enough PC to blow up a 10K (so M²) cube of TNT without the server crashing or having lag? (godmode enabled of course) and if it is, what kind of server would we need? and would we require a specially modified version of minecraft for this? and would we run into issues with bedrock and sky roof limit?
