The motion of superluminal particles in the gravitational field of a non-rotating black hole is analyzed. The relativistic Hamilton-Jacobi equation is solved for particles with imaginary rest mass. It is shown that there are no stable circular orbits and generally no finite motions for tachyons in the Schwarzschild metric and that all unstable circular tachyon orbits lie in a region extending from the gravitational radius to 1.5 times that radius. The particles with speeds exceeding the speed of light are noticed to be able to escape from the space limited by the gravitational radius. The results also indicate that low-energy tachyons near a black hole may acquire higher energies and that this in turn may lead to observable effects. https://arxiv.org/abs/1301.5428
^All very well as a theoretical exploration but it's not generally believed that tachyons can exist in our universe. The success of the standard model appears to indicate that this is the case. In the Standard Model, the Higgs field is actually an example of a tachyonic field but excitations of such fields do not give rise to tachyons. https://en.m.wikipedia.org/wiki/Tachyonic_field https://en.m.wikipedia.org/wiki/Tachyon_condensation
https://www.mnn.com/earth-matters/s...s-to-other-universes-according-to-new-quantum Researchers Jorge Pullin from Lousiana State University, and Rodolfo Gambini from the University of the Republic in Montevideo, Uruguay, crunched the numbers to see what would happen inside a black hole under the parameters of LQG. What they found was far different from what happens according to general relativity alone: there was no singularity. Instead, just as the black hole began to squeeze tight, it suddenly loosened its grip again, as if a door was being opened. The Pullin Gambini theory does fit into the function box of Lambda Calculus. A star collapses, a wide area covered representing the upper part of the hour glass. When the star collapses into a black hole the area that is squeezed tight but opens up would be the neck of the hour glass that would then allow some matter, in the form of the fields of space containing elements that are necessary to spark a Big Bang, to flow into other unknown regions of space. Once the fields of space from the the black hole come into contact with fields of space that cause a Big Bang too take place then a Big Bang might occur that would complete the transfer of space time from the upper bell into the lower bell. Your experience would be much different traveling into a black hole according to LQG, however. At first you might not notice the difference: gravity would increase rapidly. But just as you were nearing what ought to be the black hole's core — just as you're expecting to be squashed into the singularity — gravity would instead begin to decrease. It would be as if you were swallowed, only to be spit out on the other side. In other words, LQG black holes are less like holes and more like tunnels, or passageways. But passageways to where? According to the researchers, they could be shortcuts to other parts of our universe. Or they could be portals to other universes entirely. Based on humanities past of living in caves, which has been proven and not in trees, and then coming out of the cave into the light is also another philosophical similarity. Humans sought shelter from the night, space, inside of the cave that the back of the cave got smaller and smaller until only a trickle of water could pass through into another larger cavern elsewhere. Two different groups of humans connected to each other through a small trickle of life between the two. The cave being the black hole, the blockage being the rock between the other cave and the trickle of water being the matter that makes it through to the other cave. It's all relative.
LQG = loop quantum gravity https://en.m.wikipedia.org/wiki/Loop_quantum_gravity Whether the mathematics of LQG is a good description of the extremal conditions of our universe is just as open to question as for the case of superstring theory. It does appear that LQG might be more amenable to making falsifiable predictions.
https://www.physicsforums.com/threads/difference-between-a-particle-and-its-field.620374/ Particles therefore must have existed prior to the Big Bang traveling faster than the speed of light in space that when when excitation of two different particle fields interacted with each other the result was an increase in mass resulting in energy lowering to levels slower than the speed of light.

https://blogs.scientificamerican.co...-interview-with-physicist-gabriele-veneziano/ Another interesting article. Particles still had to have existed to generate heat. We have known for quite a while that the universe had to be hot at some time, because without that hot moment, we would not have been able to have big-bang nucleosynthesis and all sorts of processes that needed this high temperature. That hot moment, according to the modern view, is what must have happened after inflation. https://en.wikipedia.org/wiki/Nucleosynthesis Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons, primarily protons and neutrons. The first nuclei were formed about three minutes after the Big Bang, through the process called Big Bang nucleosynthesis. Seventeen minutes later the universe had cooled to a point at which these processes ended, so only the fastest and simplest reactions occurred, leaving our universe containing about 75% hydrogen, 24% helium, and traces of other elements such as lithium and the hydrogen isotopedeuterium. Pre-existing nucleons would not have been present prior to the Big Bang. If there had been pre-existing nucleons prior to the Big Bang that formed new atomic nuclei then those pre-existing nuclei could have come from a black hole. In order to have pre-existing nucleons that created the Big Bang the nucleons would had to have come from somewhere.
Yeah, the commonly accepted theory is that nucleons (protons and neutrons) were formed from up and down quarks and gluons during the Big Bang. You do know that heat is a measure of kinetic energy, don't you?
First Black Hole discovered. https://www.cnn.com/videos/world/2019/04/10/black-hole-first-ever-pictures-sd-orig.cnn
No, that article is not about the first black hole discovered. Do you ever actually read these things or is this thread just a clearinghouse for -stuff-
Like the Heaven's gave it to Hera Adorned in Master's Loving Arms She Lies..... Drought Plan #1 Hybrid Hydrogen Fuel Cell Electrical Power Plants. The power plants only by-product is water. In a large enough capacity the power plant could create a small lake, where additional electrical power would come from the water that has been dammed up. The power plant would create water for the dam while turning the generators of the dam during times of emergency or when the water might be low as well as creating its own electrical power turning generators. Generators like the one above when built along the border will create new towns, create jobs in Mexico and America Guarding all her gates......
Whats in a black hole. 600,000 light years across, still hardly registers in the size of the Universe. First black hole ever discovered.
As said before by others, no that is not the first black hole ever discovered, it is the first black hole of which they were able to take a direct image.
