| Abstract: |
Our first glimpse of the epoch of re-ionization will be the most dramatic of the predictable outcomes of the SKA, but the history of unexpected discoveries at radio wavelengths suggests that the SKA will do much more. In its short life, radio astronomy has had an unequaled record of discovery, including three Nobel prizes: big-bang radiation, neutron stars, and gravitational radiation. Radio telescopes have followed the pattern of exponential growth generally seen in flourishing areas of science and technology. There is no technical reason for this not to continue, but to do so will require a telescope of a square kilometre aperture (the SKA) and a shift in technology that will set new challenges. Being sensitive to neutral and ionized hydrogen gas, high-energy particles and magnetic fields, the SKA will complement other planned instruments in the optical, infrared and millimetre wavebands. |
