Is it true that humans can travel into outer space?
Yes. Extensive empirical research, historical occupational data, and physiological studies of human spaceflight confirm that humans can travel into outer space.
Verdict: SUPPORTED · 12 sources for, 0 against · Last checked
The analysis
The claim that humans can travel into outer space is directly supported by all provided literature, which analyzes physiological and medical data from hundreds of astronauts who have flown into space (e.g., Garrett-Bakelman et al., 2019; NASA Astronaut Cohort Profile, 2026). There is no refuting evidence in the retrieved sources.
