Do parallel universes exist?

The adventures of the “old” and “new” Flash, characters of the emblematic Flash of Two Worlds! comic book, published in 1961, surprised its readers over 50 years ago with the possibility of travelling in space and time through multiverses. There have been recent discoveries, such as the Higgs boson (2012), and experiments with particle entanglement at the Canary Islands Institute of Astrophysics on the Canary Islands of Tenerife and La Palma. Other studies hint at the possibility of the existence of parallel universes.

The infinite number of compositions made with string in the works of Sue Fuller evokes questions such as these.
