    The LIGO project finally has proven the existence of gravity waves and now it is time for the next step as measuring gravity waves coming from a black hole merger is one thing but showing the effects of gravity poses a different challenge.

    Do you know the phrase: No one has ever seen a black hole, and no one ever will? Well ... you are about to see one and very up close.

    I will show you a few unique images of a spinning black hole from a totally different perspective and although it technically is not yet possible to make gravity waves visible, there is a processing method which we can use to show the results of them.

    We know that photons (light) travel in straight lines (null geodesics). When photons get near a heavy mass object space-time curves and the light rays will follow a straight line in this curved space-time. Basically, light rays are bent by gravity and light rays will fall towards a gravity well slower or faster depending on the amount of gravitational force being exercised on the photons and DEUEM visualizes this effect.

    DEUEM's principle of operation utilizes the Inverse Square Law of Light Intensity and Brightness as it visualizes the effect of gravity on multiple measured light source strengths and displays the effects of strong – and weak gravitational lensing on light rays which have been observed with heavy mass objects like galaxies, neutron stars, supernova, quasar and black holes.

    Space is not empty as it is full of (gas)molecules, interstellar dust, particles, matter and dark matter. We know from scientific research that stars that come near black holes lose matter to the black hole and that an accretion disk is formed. The same thing happens with interstellar dust. The heavier the gravitational force the more dust particles are heading towards the gravity well and as regions of high gravity show higher density of particles and therefore luminous intensity, diffuse reflection and attenuation is different from the regions of lesser gravity we see an increased brightness and light intensity in high density regions.The opposite happens with shock waves from a supernova. We cannot see the waves but we can visualize the effect the waves have on interstellar matter.

    DEUEM is the math but the final processed image is a computer generated image that shows an artistic impression of the light rays and we are in fact using mathematics as a canvas to visualize light rays being affected and bent by gravitational force.

    Enjoy the show and carefully read the message in the video!
    This is a preview and in the next video we will show you more!
