I have been on various forums regarding change. Climate change explanation expectation in the last paragraphs. There is evidence that humans evolve to a degree of civilization and through catastrophe collapse to primitive again. It is something to avoid. I estimate that change also affects communication because that is what drives civilized society. Look up in Wikipedia or here for Boskop Man.
I believe the Bible is a blueprint of exactly what is going to happen. We just do not know how to read it yet. After a couple of experiences I believe there is much more to the Bible story and that it has been given to the ancients as if seen by the future. So I looked for a science that might come close.
If one looks at Einstein's idea that wormholes are the predominant formation meaning a stretching and moving of space it is possible. As soon as space is stretched then time has a shape and can be seen from within and from the outside. An example of seen from the outside is the WMAP early universe survey where it has been recently discovered that the heat distribution is of the same shape as the structure of galaxies in our present universe. The early dark matter has a flow, discovered in the last few weeks. The early dark matter is stretched to one side, also discovered in the last few weeks. There is no dark energy in the early universe survey because we are looking at it from the outside.
From inside this current universe we see matter and dark matter account for a quarter of the universe. Dark energy accounts for the other three quarters. That works with a forward and reverse no touching twin line of stars connected. Try wrapping an elastic band around your fingers twice and see the tension across one strand is one quarter. We are in that one forward flow and the other three are energy.
Matter connected in time meaning the shape of time indicates a partial reverse as in magnetic fields when we turn a corner. Note time can not completely reverse because matter would back up over itself. Back to the rubber band analogy and with a bit of shaping a circle and a cross can be made. That is significant. Now the Bible does not pull punches because it clearly says a third of the people will die. For time to reverse fields one would have to calmly wait the time of reverse which would be difficult for the untrained or small children and pregnant women could sustain severe injury if a baby is distressed.
For matter to be connected in time then time would have shape. For that shape see local bubble or local fluff as the heat shape the solar system is traveling through. It is an hourglass meaning a bottleneck in time and it bends at an angle indicating a change in direction which we see before entering the bottleneck. For us it will appear straight as we go through. Also time symmetry affects the nuclear weak force. Critical mass for nuclear weapons will become smaller and less stable. That is already seen in that superpowers are 'advancing' to smaller tactical high accuracy weapons. The British have had to move the Trident missiles due to unacceptable high radiation levels. This apparent linear decline in mass size will quickly become exponential. There will be a time when only foot soldiers will march as electronics will fail because they use electricity. Nuclear isotopes are in the family home as smoke detectors, in offices and theaters as exit signs and in schools and hospitals as teaching and healing tools. By far the most nuclear material is in waste although the power generating industry contributes its fair share.
The transition will take a time and so the hour and the day observed around the world will vary according to the dateline and the longitude. It will happen. The poles currently are experiencing rebound due to the lowering of the ice weight upon them. Every percent shift in the roundness of the earth is a two hundred meter difference in ocean height. Magnetism attracts and so the shift of the field to a distant new position will cause stresses as the earth finds its new shape and ocean flow.
This is what is likely if the universe is fully connected in time from end to end and all things known. People complain they would not want life if it is deterministic as the idea suggests. Do you value being who you are each day when you wake up? Is it important to know your name, your job, your bank account? You can not access the past to change those details just as you can not access the future. Your present, your now is reality and the perception of reality is the life you live. It is not so bad. A guitar string does not move along the neck of the instrument but when strummed can produce wonderful sounds (and some shockers as well).
The future I worry about is the scorpion sting and days of pain that must be suffered. Only in the last eight years has there been the power to break symmetry which means breaking reality in a connected time universe. It takes ten or more times the power input to make the heaviest particles. One theory is that antiparticle may travel to the past and change it on us. Why does no one look ahead and ask could the missing energy from the experiments be causing radiation, burning and suffering in the future?
This is if science is wrong about what matter really is. Currently we do know that scientists can not explain what dark matter is or what dark energy is. Giving something the word dark means invisible, unseen and unknown. Scientists also do not know what matter is. That is why they experiment ... even at the risk of being wrong.
More of the observations are the super cluster Virgo galaxy M87 and a twin M77 which would be expected in a time reverse through a super structure required to bounce our Milky Way galaxy. We have an influence exerted on our galaxy by Virgo and so relative to any observation our Milky Way galaxy should not be flat. When we see the sun we see where it was eight minutes ago. Likewise any induced movement should give our Milky Way galaxy a conical shape. So the entire galaxy is being evenly pushed in a strange direction as shown by our passage in the local bubble, a bubble we are coming to the end of.
Climate change in these circumstances would require a charge discharge noticed as heat increasing quite rapidly on approach. Mosquitoes were a sign of a change in times as known in ancient Egyptian times. Global heating precedes a cooling cycle or ice age with rapid onset in times as little as a hundred years. This would indicate sacrificing heat on transition to take on the opposite charge. On the quantum scale it is hard to imagine how measurements in pico seconds and femto seconds producing cycles like the 41,000 year and 100,000 year cycles of the sun. Harder to see how the cyclical volcanic eruption of Yellowstone would occur every 600,000 years geologically and magnetic pole reversal every 700,000 by residual magnetic field found in the deep ocean rifts.
Likely there is going to be a rapid heat increase then transit followed by tidal events and then rapid cooling followed water shortages caused by loss of oceans through fractures connecting deep salt layers. Deep sea mining operations have pierced salt layers to get to oil. If that becomes a weak point then because salt formations and oil are commonly found together the relatively stable and unchanging environment we are used to may be one to survive and then do as much to preserve as is possible.
If this comes about then society will need to rebuild from basic tools. Learning to communicate again under changed conditions would also be essential and may require some sort of pictorial record as the visual center of the brain is the most rapid to adjust due to necessity while hearing is a learned skill.
I use the references as a guide on the premise that consciousness exists ahead and behind us in time. I also believe that due to current experiments that it is just as unlikely we will be around long enough to see it for ourselves. As for the death of a third of humanity it depends a lot on timescale of the transition for determining if it is a best case or worst case scenario.
