10. Besides black holes, another strange object that can be found in the cosmos is a wormhole.

However, its existence is yet to be proven. Wormholes, as described by physicists, are ‘shortcuts’ for faster traveling between galaxies, universes, or even timelines. It has no Event Horizon which means the gravitational pull here is not strong as black hole’s. But, it is also fatal. High Radiation levels and the exotic matter inside might get you.
