Bedrock is the bottom-most layer of blocks in the Minecraft world, which acts as an impenetrable barrier between the Overworld and the Nether. It is the strongest block in the game and cannot be broken through normal means. However, there are a few methods that can be used to break bedrock in Minecraft, albeit they require the use of glitches or external tools.
Breaking bedrock can be useful for a variety of reasons. It can allow players to access the Nether without having to find a portal, or it can be used to create hidden bases or secret rooms. However, it is important to note that breaking bedrock can also cause instability in the game world, so it is important to use caution when doing so.
