      Sounds like the climax of a story. Someone running away from some situation and eventually, atop a mountain and under the darkest night sky, a burst of galaxies colkiding. Maybe metaphor for the collisions in the story.

    There's the problem of, if the universe has no edge, then it must loop back on itself at some point or something, unless there simply is an infinite amount of space & stuff in the universe. My gut tells me that we will find some paradox like with measuring information around black holes, and we'll discover that we can never find out and measure around [or at least not travel to and find out] where any possible looping back point of the universe might be, because perhaps we'll have to transit extra dimensions in order to do it, and perhaps accessing those hidden dimensions would require going back in time toward the beginning of the big bang

    This whole discussion of the genetic variation of the spots and the comic relief of Black Panther, is actually a lived experience of being able to know how another said group is going to react to a situation, based on their “spots”. It is not pre-judging, it is self-knowing what my own “spots” are telling me and it’s generalized action across time and space.

    On the nature of "black holes"
    A "black hole" is an astrophysical object at the level of which the equations of general relativity give infinite values; he constitutes a gravitational singularity in the space-time.
    So, why have some astrophysicists tried to study what is beyond the event horizon of "black holes" using unrealistic models of gravitationnal quantum physics, when the quantum physics study matter at the subatomic level, while a "black hole" is an astophysical object that belong to the univers which is a macroscopic physical system that is subject to the entropy and the arrow of time?
    And why is an astronaut or an object that falls into a "black hole" always represented falling there vertically without passing through the accretion disk, when it should describe a spiral trajectory around the "black hole" and therefore necessarily pass by its accretion disk, like what happens to a comet before it is disintegrated by the Sun?
    Indeed, as Albert Einstein postulated in 1905 that the speed of light in the vacuum is a fundamental constant of physics and that it is a limiting speed independent of the speed of the source that emits the light and that no massive body can reach the speed light ; so, I postulate that, all the shadow of a "black hole", whatever its mass, is a gravitational singularity and no massive body can reach the event horizon of a "black hole", and I assert that beyond the event horizon from each "black hole" there is a very large closed iron door which sits at the base of a tower of an enormous fort built using an extremely strong and compact material. This fort is more than 120,000 light years high, and it surrounds the entire First Heaven, while the solid ground of the First Heaven is the roof of the universe. And in the First Heaven there is the House of Glory , Hell, and great white palaces.

    If some astronomers and astrophysicists tell us: "With our observations, we can go back to 10^(-43) second after the big bang and we are very close to the beginning of the universe.", I then ask them next question: If an extraterrestrial craft in the shape of a tesseract hypercube lands on Earth and unfolds into a tesseract hypercube's net with a written message challenging you to return the tesseract hypercube's net to its original dimension 4 hypercube form, will you then be able to take up the challenge?

      @@mac2654 Complement of relativity
      Relativity was introduced in physics by the Galilean principle of relativity in the early 17th century, and Albert Einstein formulated the postulates of special relativity in 1905 ; and he developed special relativity using Lorentz transformations. Then Einstein formulated the equivance principle and developed general relativity using Riemannian geometry in 1915. After that, Karl Schwarzschild in 1916 and Roy Kerr in 1963 solved Einstein's equation of general relativity ; but their solutions proved the existence of gravitational singularities in the universe, and on these gravitational singularities, some terms of the Schwarzchild and Kerr metrics become infinite.
      But, in recent decades, some astrophysicists have tried to circumvent the Schwarzschild and Kerr singularities by using Eddington-Finkelstein coordinates to allow massive particles to cross the event horizon of a "black hole." . If they were right, they should also have abandoned the Lorentz transformations in special relativity and looked for other transformations that would allow massive particles to exceed the speed of light in the vacuum while maintaining the invariance of the physics' laws in all inertial frames of reference.
      Thus I complete Albert Einstein's general relativity by formulating the following postulate 《All the shadow of a "black hole", whatever its mass, is a gravitational singularity, and no massive body, which is not a "black hole", can reach the event horizon of a "black hole". And beyond the event horizon of each "black hole" there is a large closed iron door, which is one of the gates of the First Heaven, which is the first of the Seven Heavens.》.

      Morever, the cosmic microwave background does not validate the big bang theory because in 1965, the German physicist Hans Bethe misinterpreted this background noise of the universe and some evolutionary and Darwinist physicists and astrophysicists who have the power to decision in the scientific community immediately considered that this false interpretation of Hans Bethe is an absolute truth.
      Indeed, the cosmic microwave background has been caused by the cracking of the Heaven.
      So, Heaven is cracking because the Seven Heavens are filled with angels who pray God and who are ready to carry out his orders - to recover the souls of human beings, jinn and animals who are in agony; make the Earth shake in certain places; throwing shooting stars at the devils sent by seers or sorcerers to listen to the information from Heaven transmitted by the angels who descend to Earth; make the rain fall... - until the Last Judgment Day.

    At the time of the creation of the universe on six days (Sunday to Friday inclusive) 4.5 billion years ago and beyond the event horizon of "black holes", science meets the Saints Scriptures (the Torah, the Gospel and the Qur'an).
    So, when Galileo said to the cardinals during his trial: "Let us tell you how heaven is and tell us how to get to Heaven.", he was a little wrong; because after having definitively proven the existence of "black holes" by photographing the shadows of the "black holes" M87* and SgrA* and their accretion disks, astronomers and astrophysicists have shown us where are located the doors of the First Heaven who is the First of the Seven Heavens.
