When it comes to telescopes, bigger is better. Or is it? If we want to study galaxies in the furthest corners of the cosmos, one option is to go large – the first 40 metre diameter telescopes are now under construction. But there is another possibility, linking up multiple smaller instruments across the world. Andrew Pontzen talks to cosmologists Amelie Saintonge, Laura Wolz and Martin Rees (who is joining the event digitally) about emerging technology and the discoveries it will enable.
