Einstein’s Blunder

Professor Roberto Trotta






Roberto Trotta is Visiting Gresham Professor of Cosmology and Professor of Astrostatistics at Imperial College London, currently on leave of absence to the International School of Advanced Studies in Trieste, Italy, where he is part of the senior leadership team establishing a new Data Science Institute.

His research focuses on cosmology, machine learning and data science. An award-winning author and science communicator, he is the recipient of the Annie Maunder Medal 2020 of the Royal Astronomical Society for his public engagement work.

Roberto Trotta’s lecture series are as follows:

2021/22 The Frontiers of Knowledge

When Albert Einstein tweaked his newly invented equations of General Relativity in 1917, he had one goal in mind: to find a solution that described a closed, static, eternal universe. He therefore minted a new universal constant to make it work. After Hubble’s discovery of the expansion of the universe in 1929, Einstein reportedly declared it his “greatest blunder”. In 1998 observations of distant exploding stars brought Einstein’s “blunder” back into consideration: Einstein might have been right the first time around.
