But wormholes. These are tunnels in spacetime. Einstein (a famous scientist) said that our three dimensions, length, width and depth, can be combined with the fourth dimesion, which is time. He also said that an easy way to imagine it is to think of it as a grid, the y-axis is space and the x-axis is time. He also said that you could bend this spacetime around, like a rubber sheet. Wormholes are tunnels from one part of the sheet to another, so they are passages from one part of spacetime to another. They are very unstable (and theoretical!) so if anyone enters one and survives to come out the other side, you would not be able to get back the same way.
Hope you understood that!
