Time Machines: Talks Programme
Martin Ward - A time machine that can look back 13.5 billion years: The Telescope
To complement the exhibition, Time Machines, a series of talks and events has been scheduled. Over the course of the exhibition there will be a number of lunchtime and evening events with speakers covering a broad range of themes to complement the exhibition content. Please do keep an eye on our website for more details.
Martin Ward, Temple Chevallier Professor of Astronomy in the Department of Physics, Durham University, will present a talk entitled 'A time machine that can look back 13.5 billion years: The Telescope':
"Seeing the distant past is easy (as distinct from visiting it!). Because light travels at a finite speed, looking back in space is also looking back in time. Take as an example the
Orion Nebula, which is visible in a small telescope. If we could instantaneously transport ourselves there, and we had access to a super powerful telescope trained on the planet Earth, we might see, for example, the first Christian missionaries from Ireland arriving to evangelize England or the first printing of the holy Koran. But we would need to wait more than century to See Alfred the Great crowned king! I will describe a trip back in time some billions of years to a time when the Earth was formed, when galaxies were born and when the Universe came into existence."
This talk will be free of charge. Booking is not required for lunch time talks but seating will be allocated on a first come, first served basis. Staff at Palace Green Library will be able to provide directions to the Pemberton Building if necessary.
Enquiries regarding talks should be made to Palace Green Library on 0191 334 2976.
