    You could say the same about the moon, but especially with mars I wonder wtf we are going to do there?

    We're going to start the reactor and free it.

    As close as I will ever get to space travel.

    Amazing read, thank you Khanivor.
    I'd love to be in a meeting where all the mobile phones start ringing at once.

    I was in meetings like that back when we were finding the Higgs Boson. It was pretty amazing. :-)

    Spin is in charge of collecting the Higgs from the other particles (they are purple) and put them in a separate box.

    Lots of videos out there about todays big news, Veritasium explains it best as always.

    Is it me, or is the sound they recorded of the neutron stars almost identical to the effect used for Strengthometer of News in HIGNFY?

    Fair play and well done.

    I do blame you for the parallel universe you all created though.

    I love reading about these developments but I struggle with the scale. The distances involved mainly but also the density of a neutron star for example.

    There's only so many zeros my little brain can process.

    A teaspoon of a neutron star is about 1000 tonnes... the light took 130 million years to reach us.

    This stuff inspires genuine awe. Both at the scale of he universe, but also at how far we have developed technology that we can even measure this stuff. I mean, a hundred years ago we still used abacuses. The microchip has only been around since the 1950s.

    The most amazing part are the gravitational wave detectors. They measure the length of their 4km long detector-arms to within one 10000th the width of a proton.

    The fun stuff will come when they put a similar detector in space, free of all the noise we have here on earth.

    One thing I don't get after watching the Veritasium video I posted above, is that the Fermi gamma-ray detector was 1.7 seconds slower than the LIGO gravitational wave detector.
    As far as I know, gamma rays and gravitational waves both move at the speed of light.

    So after traveling 1.229x10^21 km (130 million light years), they arrive with 509646 km (1.7 seconds x 299792 km/s) separation.

    I was thinking the gamma rays were obscured for 1.7 seconds by neutron star debris, but I think gamma rays have a tendency to fly trough just about everything, especially the high energy ones.

    While it is marvellous what we can discover, it sometimes makes me sad what we'll miss. We're on the cusp of some really great things, which makes it somehow worse that we're so close yet we'll probably just miss out.

    Though maybe other people have thought the same at other big humanity milestones.

    Meh, I just microwaved a frozen meal, I got a super computer in my pocket that allows me to communicate with everyone in the world, things are alright.

    I was with you as far as the football fields. My brain gives up at the concept of 2 LetsGos though, 14 can just fuck off.

    The universe would collapse on itself, the laws of physics shattered eternally.

    Nothing can be that dense. NOTHING!

    Excluding the mass that has been radiated away as energy, this thing had a mass of 1.1+1.6=2.7 times the mass of the sun. If 1 LetsGo is 1/14th that mass, he would collapse into a black hole if we presume he is smaller than 569m.

    Yeah I know, I'm Belgian as well remember?

    I just encounter both spellings online in equal measures and in such situations I just use whichever randomly. Let the masses sort it out, someone will always end up (dis)agreeing anyhow.

    Edit: Chrome swallowed part of my sentence there, interesting.

    Sorry I only remember someone's nationality when they are from Switzerland. Like Spindizzy and ecosse.

    1 LetsGo being the size of about 60 london buses parked end to end enhances my mental image of him no end!
