This is the text (if you need help).
Time travelers have been invited to Stephen Hawking's memorial service. The legendary cosmologist and author died on March 14. Thousands of well-wishers lined the streets in England for his funeral. His family has arranged a special ceremony for people to remember and celebrate his life. They have invited time travelers. Hawking famously wrote that: "If time travel is possible, where are the tourists from the future?" Now they have the chance to travel back in time. People with birth dates up to December 31, 2038 can apply to attend the service.
The concept of time travel intrigued Professor Hawking for decades. In 2009, he held a party for time travelers at Cambridge University. There was champagne and a banner saying: "Welcome time travelers". However, no one from the future went. The Stephen Hawking Foundation is organizing the memorial service. It is yet to receive any replies from a time traveler. The deadline to reserve a place at the June 15 event is today. The Foundation said it was still possible. It said: "We cannot exclude the possibility of time travel as it has not been disproven to our satisfaction."
Back to the time travel lesson.
