    A version of this video (and all my other educational ones) without background music is available on my DailyMotion: www.dailymotion.com/video/x891x9x
    If this video garners enough interest, I will try to convince a former colleague of mine to do a Q&A all about the things I’ve talked about in this video. Please respond to this comment with your questions related to: gamma-ray bursts, high energy astrophysics, x-ray astronomy, lobster eye optics, and the heliosphere.

      the gravity waves travelled at the speed of light as it was picked up exactly the same time as the light from the gamma Ray burst?
      what can this say about both gravity and light?
      is there anything new to come from that result?
      merci

    • @ImprobableMatter
      @ImprobableMatter  2 года назад +2

      To answer your question in short: gravitational waves traveling at light speed rules out many possible advanced theories of gravity and quantum gravity. Therefore, we are more confident about the remaining theories and their parameters being correct. I will cover this in more detail if I am able to do a Q&A video.

      @@ImprobableMatter great, look forward to it. I had never thought of it though I can see how the speed of both being identical solidifies a fact for theorising different ideas moving forward. I wonder what else travels at that speed?

    • @ImprobableMatter
      @ImprobableMatter  2 года назад

      @@forloop7713 The angular resolution is determined by imaging a point source of x-rays (usually at the end of a meters-long beamline) and calculating the angular size on the detector. Then a similar criterion can be applied to this as visible telescopes. I can certainly discuss this at greater length in a future video.

    Great presentation, as usual!
    I was aware of grazing incidence astronomical Xray optics back in the late 80's. The company I worked at did some work diamond turning segments for some telescope project, I can't remember what one as I didn't work directly on it.
    It's kind of funny how aspects of nature's creatures can inspire technology. I don't know if that is the case here, but the principle is the same. In material science there is effort to exploit the tremendous boost in material properties gained by the proper arrangement of low strength constitutes, as in the case of abalone shell.

    • @ImprobableMatter
      @ImprobableMatter  2 года назад +4

      Existing x-ray telescopes such as the Chandra have been used to study quasars already. Since these are point sources in a known location, the lobster eye telescope's advantage in field of view would not help, but they could certainly be used in principle.

      @ericeaton2386 2 года назад +3

      @@ImprobableMatter Ah I see. So then the lobster eye telescopes advantage is more about locating new, faint sources, right?

    • @ImprobableMatter
      @ImprobableMatter  2 года назад +5

      Yes. The two upcoming missions showcase the advantages of the lobster eye: scan a relatively large portion of sky in a short amount of time, and with a small size you can pack it with a bunch of other instruments on a small satellite.

      Yes, in that case make a large array of square channels of polished metal and taper them so that they get smaller at one end. Maybe try a football/soccer ball type of arrangement of channels that get narrower inwards.
