- In cosmology, galaxy filaments are the largest known structures in the universe, consisting of ‘walls’ of gravitationally bound galactic superclusters. These massive, thread-like formations can reach 80 megaparsecs h−1 (or of the order of 160 to 260 million light-years) and form the boundaries between voids. Galaxy filaments form the cosmic web and define the overall structure of the observable universe.
I am not a comic, I have never told a joke. The comedian’s promise is that he will go out there and make you laugh with him. My only promise is that I will try to entertain you as best I can.
