Stephen Hawking's voice will be beamed 3,500 light years into space
(CNN) -- Renowned physicist Stephen Hawking spent his life teaching the world about space, so it is only fitting that part of him will end up among the stars.
As Hawking's ashes are being interred between the graves of Charles Darwin and Sir Isaac Newton at a memorial service on Friday at Westminster Abbey, an antenna in Spain will beam his voice out into space, toward a black hole.
Hawking, a committed atheist who spent much of his life researching black holes, died in March at age 76 after battling a motor neurone disease for 55 years.
His voice will be set to original music
Greek composer Vangelis -- yes, the "Chariots of Fire" guy -- set the physicist's voice to an original piece of music for the occasion. It's meant to send a message of peace and hope, Hawking's family said in a statement.
Mark McCaughrean, senior adviser for science and exploration at the European Space Agency, told CNN the musical piece is about six-and-a-half minutes, with a voice-over by Hawking in the middle. He said it's pretty somber and is about considering the Earth as a place people come from and need to look after.
Scientists will use the Cebreros antenna in central Spain to send the recording toward 1A 0620-00, the nearest known black hole -- some 3,500 light years from Earth. It's one of the most famous black holes in the universe, McCaughrean said.
It will take about 35 minutes to send the music into space. After the ceremony, the music will be played at a reception for people in attendance. Every person at the ceremony will receive a CD with the piece of music, which will be released to the public at a later date.
"It's a nice story overall, and we're very honored to have been asked to do this," McCaughrean said. "Hawking is a highly influential scientist and public figure. This is a lovely, beautiful symbolic gesture."
The recording will become locked just outside the black hole -- but black holes don't last forever, McCaughrean said. They evaporate over billions and billions of years by emitting Hawking radiation -- named for the late physicist, of course.
"It's his own radiation which will actually cause it to disappear in the end," McCaughrean said.
Hawking's family loves the idea
Hawking's family is thankful for the memorial service -- and that his voice will travel to space.
"We are so grateful to Westminster Abbey for offering us the privilege of a Service of Thanksgiving for the extraordinary life of our father and for giving him such a distinguished final resting place," Hawking's children said in a statement.
"This is a beautiful and symbolic gesture that creates a link between our father's presence on this planet, his wish to go into space and his explorations of the universe in his mind," Stephen Hawking's daughter, Lucy Hawking, said.
Actor Benedict Cumberbatch, who played the scientist in a 2004 BBC biopic, will be among those giving readings at the ceremony, according to the Stephen Hawking Foundation.
Astronaut Tim Peake and two of Hawking's oldest professional friends, cosmologist Martin Rees and Kip Thorne, an American physicist and Nobel Prize winner, will also be in attendance.
A public lottery decided which 1,000 members of the public will join the Hawking family and their guests at the service. Around 25,000 people applied for tickets.
"We believe it to be vital that science and religion work together to seek to answer the great questions of the mystery of life and of the universe," said the Dean of Westminster, the Very Rev. Dr. John Hall, when the location for the internment was announced.
Isaac Newton was buried at Westminster Abbey following his death in 1727, as was naturalist Charles Darwin a century and a half later in 1882.
Many considered Hawking to be the greatest scientist of his generation, overcoming a debilitating disease to gain a worldwide following for his brilliant work in theoretical physics.
He was born in Oxford, England, in 1942 on the 300th anniversary of the death of astronomer and physicist Galileo Galilei.
Along with fellow physicist Roger Penrose, Hawking merged Einstein's theory of relativity with quantum theory to suggest that space and time began with the Big Bang and would end in black holes.
He also published hugely popular books that allowed readers to join him in probing the mysteries of the universe. His landmark "A Brief History of Time" sold more than 10 million copies.
In 1963, shorty before his 21st birthday, Hawking was diagnosed with amyotrophic lateral sclerosis, a neuro-degenerative disease, and although he required a wheelchair and a speech synthesizer, Hawking lived for many years beyond the prognosis.
