The Newtonian constant of gravitation, a constant too difficult to measure?

Theo Murphy international scientific meeting organised by Dr Terry Quinn CBE FRS, Professor Clive Speake and Professor Jun Luo

Events details

The Newtonian constant of gravitation, G, is the only fundamental constant of physics for which the uncertainty given in successive CODATA evaluations has increased. Measurements made since 2000, using a variety of methods, now show a spread of values more than ten times their estimated uncertainties. This meeting explored possible reasons for this and generated some proposals for new measurements that might resolve the present impasse.
