Why is Christian Science in our name? Our name is about honesty. The Monitor is owned by The First Church of Christ, Scientist, and we’ve always been transparent about that. The church publishes the ...

Weight is the force acting on an object due to gravity - it has the unit newtons (N) and acts towards the centre of a gravitational field. So weight is a gravitational force on an object that has mass ...

Scientists have calculated the ancient signals that emerged just after the Big Bang. These signals come from a long-lost cosmological phenomena known as ‘oscillons,’ the gravitational wave sources ...
