Hubble Finds Double Einstein Ring

Einstein Duble brings us news that astronomers using the Hubble Telescope have discovered an extremely rare double Einstein Ring. Occasionally, galaxies or other bright objects are located in such a way that they are behind another galaxy when viewed from Earth. When light from the further galaxy passes a sufficiently massive closer galaxy, the path of the light is bent inward from all sides, creating a "ring" effect. In this case, not one, but two galaxies are directly behind the foreground galaxy, so the gravitational lens produces two distinct rings. Quoting Presscue: "The distribution of dark matter in the foreground galaxies that is warping space to create the gravitational lens can be precisely mapped. In addition, the geometry of the two Einstein rings allowed the team to measure the mass of the middle galaxy precisely to be a value of 1 billion solar masses. The team reports that this is the first measurement of the mass of a dwarf galaxy at cosmological distance (redshift of z=0.6)."

    Any slit experiment is fine with me!

    Wow, you really pissed off some idiot who knows how to hold a grudge. Believe me, it happens. A post of mine once got modded overrated about two days before the story got archived.

    In the same way that every Republican/Democrat/ is exactly the same and agree 100% on everything? Not to mention there's a difference between a libertarian and Libertarian.

    Mod this whole subthread as offtopic.

    Some Libertarians might be against funding things like Hubble. I personally am more concerned with personal freedom, and a balanced budget

    So how exactly are you a Libertarian, then?

    2 poles. Light,positive,creation --> dark,negative,destruction.
    Every force field is the recording of the flow between poles.
    "Energy" is a convention to describe a waveform's peak. "Dark energy" is the sink. Time is the frequency of the signal.
    Every 0-dimensional spot can alternate between +/- as demanded from their adjacent fields. Reality's sum is always zero.
    Matter is energy in low vibration. We are the waveguides. Forces and fields are recordings of that flow.
    Sun is full positive, we are slightly positive, the gas giants even more positive and the ice giants negative.
    Our solar system is in equilibrium with that structure. Maybe we're a hydrogen isotope.
    We'll soon experience a "collision" with a galaxy "swarm".
    Outer fields will compress the orbits on our solar system. Fusion.
    My bet is that gas gients will collide and our solar system will be binary again. The creation-destruction spiral never ends it goes in and out of our level/plane of existence to infinity. Think .
    Let's accept it and move on. Shrinking fields to contain fusion reactions and cancer tumors could work. Let's swarm.

    Hi AC, thanks for the lovely reply. It made my day all bright and happy like a shiny farthing found under a night-soil cart.

    Everything's peachy keen now and lovely-jubbly. Or something like that. Apparently I'm upper-crust English or some-such, and must use their inane rhyming rhubarb to talk like some babbling idiot out far too long in the midday sun (well, it's just mad dogs and us Englishmen, eh?). Well... toodle-oo and all that, eh what? Chocs away and I'm off for scones and high tea with the Queen!
