There is a well-known cliche in astronomy about neutron stars, which says that a teaspoons worth of neutron star weighs some incredible amount. But there is diagreement about how much. A quick Google search for “teaspoon neutron star” produced several conflicting answers. NASA claims 1 billion tonnes, while Cornell University claims 10 million. Somewhere called Lake Forest College, Illinois claims 100 million tonnes.Finally the University of Southhampton assert that it weighs as much as 20,000 elephants. But not knowing the weight of an standard astronomical elephant, this is not very helpful.
However, one daring scientist has realised that the problem may not be with the neutron star, but with the teaspoon. So he has done diligent research to find the actual volume of a teaspoon, which he reports here.
