#explain the joke: batel brov is a halachic principle which means nullified in the majority

ship of theseus is so easy. Yeah it’s the same ship. Each piece that’s replaced is batel b’rov of the rest of the ship and becomes the same ship as the rest of it. The only problem would be if you replaced the ikkar of the ship in one go. Now of course there’s a machloket about what the ikkar is- some say the mast, while others say it’s a continuous rov of the hull, while still others say that it’s just enough of the hull that the ship couldn’t stay afloat regardless of whether it’s contiguous- but the principle is simple.
