Salvatore Capozziello came to Lisbon to say that time machines will emerge, and he just doesn’t know if they will take “two or 100 years” to create

Salvatore Capozziello, cosmologist and professor at the University of Naples, arrived in Lisbon to give a lecture this Tuesday at the Faculty of Sciences of the University of Lisbon (FCUL) traveling in the classic way, but has not yet given up hope that, one day, engineering creates machines that can transport particles or even objects and humans to the past or future.
