"We come to celebrate the life and achievements of Stephen Hawking in this holy place where God has been worshiped for over a thousand years and where kings and queens and the great men and women of our national history and global influence are memorialized".
Science met science fiction in London, Friday, with "Avengers" and "Star Trek" actor Benedict Cumberbatch among those paying tribute to the late physicist professor Stephen Hawking.
Per ABC News, the service also included music by Greek composer Vangelis.
It's meant to send a message of peace and hope, Hawking's family said in a statement.
The broadcast is to be beamed into the nearest black hole, 1A 0620-00, by the European Space Agency via a satellite in Spain. He said it's pretty somber and is about considering the Earth as a place people come from and need to look after.
The memorial stone placed on top of Hawking's grave included his most famous equation describing the entropy of a black hole. "Hawking is a highly influential scientist and public figure". He also calls it "a lovely, attractive symbolic gesture".
Specifically, it will be directed toward the nearest black hole.
"It's his own radiation which will actually cause it to disappear in the end", McCaughrean said.
His voice will be broadcast into space after the service honoring his life.
The service featured readings from Benedict Cumberbatch, who played the physicist in a BBC drama, and astronaut Tim Peake.
Readings were given by top figures from the science world, including astronaut Tim Peake, astronomer royal Martin Reece and Hawking's collaborator and Nobel prize victor Kip Thorn. There were 25,000 applications for 1,000 available tickets.
More than 3,000 people have been buried or commemorated at London's Westminster Abbey, one of the capital's most historic and recognized landmarks. Renowned for his works in theoretical physics, Hawking will be interred between other prominent British scientists, including Sir Isaac Newton, who formulated the law of universal gravitation and laid the foundations of modern mathematics, and Charles Darwin, whose theory of evolution was one of the most far-reaching scientific breakthroughs of all time.
