  • When black holes merge, the world shakes.
    Such quakes in space-time are now detectable and indeed the detection of such gravitational waves from cosmic coalescences comprises an entirely new type of astronomy that is completely independent of light itself.
    A lecture by Katherine Blundell OBE
    The transcript and downloadable versions of the lecture are available from the Gresham College website:

    One detail omitted that really shouldn't have been, it doesn't add that much complexity, is that the laser beams are reflected back and forth over the 4 Km path about 300 times before being sent to the detector, making the actual distance traveled closer to 2400 Km, a 1200Km-arm interferometer. This takes nothing away from the still unbelievable sensitivity of these things!

    The idea of spacetime having stiffness is mind bending.

    Why is there a pair of gravity peaks close to the gravity wells just before merging occurs? What does it mean for the level to be *above* the background level like this?

      Because gravitational waves become stronger and confined to smaller and smaller an area just before they coalesce.

    It seems like an unfeasibly small deflection. Kudos to those who initially had the belief it could be measured.

      If not, just search for the color of the series..
      Each new series has a color 😎👍
