The hydrogen ions travel at 99.999,999,1 per cent of the speed of light. Their time slows down by a factor of 27,777,778. One second for one of these protons is about 11 months for us.
Signal was produced by two black holes colliding 1.4 billion light years away.
LISA Pathfinder mission sets record for truest free fall ever achieved with a humanmade object, and paves the way for the LISA space-based, gravitational wave observatory.
Produce and detect gravitational fields at will using magnetic fields, control them for studying them, work with them to produce new technologies -- it sounds daring, but one physicist has proposed just that in a new article. If followed, this proposal could transform physics and shake up Einstein
