Minecraft: Indestructible Blocks?

What you hit sir, is called Bedrock. Bedrock serves as a barrier to keep you from falling from the world. This block is indestructible in Survival Mode but vulnerable in Creative Mode. If broken through the bottom bedrock in Creative, you fall into the End Of The World and die. Try to mine around bedrock, you get good stuff. (also, there is a block called obsidian that is formed by combining lava with water, it is pitch black and is only minable with diamond pickaxe, and even so, it takes a while to break. Just saying that in case you ever come across it because if you don't know what Bedrock is, it is assumable that you are a noobie.

It is called bedrock. It is to stop you falling down into nothingness.

They're called bedrock, they're indeed there to prevent you from dropping into an empty void.
