We must address a key obstacle to our new age of space exploration

Advances in rocket technology are exciting, but we need to investigate how non-terrestrial gravity affects astronauts' psychology and cognition, says neuroscientist Elisa Raffaella Ferrè

Comment

Quantum superposition or quantum entanglement concept illustration. Superposition is the ability of a quantum system to be in multiple states at the same time until it is measured. Quantum entanglement is a physical phenomenon that occurs when pairs or groups of particles are generated or interact in ways such that the quantum state of each particle cannot be described independently.
