Physicists prove time travel is ‘mathematically possible’

time travel

Scientists in Australia claim to have proved that time travel is theoretically possible after solving a logical paradox.

Physicists from the University of Queensland used mathematical modelling to reconcile Einstein’s theory of general relativity with classical dynamics. The clash between these two systems is behind a famous flaw with time travel, known as the grandfather paradox.

Einstein’s theory allows for the possibility of a person using a time loop to travel back in time in order to kill their grandfather. However, classical dynamics dictates that the sequence of events following the grandfather’s death would culminate in the time traveller not existing in the first place. 

“As physicists, we want to understand the universe’s most basic, underlying laws and for years I’ve puzzled on how the science of dynamics can square with Einstein’s predictions,” said Germain Tobar, who led the research. “Is time travel mathematically possible?”

Astrophysicist Claims Time Travel is Possible

‘If time travel is possible, where are the tourists from the future?’ Stephen Hawking asked in A Brief History Of Time.

Hawking also famously staged a party for time travellers, complete with champagne and a banner saying, ‘Welcome time travellers’.

None showed up – but time travel itself might actually be possible, according to one astrophysicist (although it won’t be easy, and it involves alarming forces like supermassive black holes).
