Organisers of Prof Stephen Hawking's memorial service have seemingly left the door open for time travellers to attend.
Those wishing to honor the theoretical physicist, who died in March aged 76, can apply via a public ballot.
Applicants need to give their birth date, which can be any day up to 31 December 2038. Prof Hawking's foundation said the possibility of time travel had not been disproven and could not be excluded.
