'What are the biases a ship sets to submerge into dark matter?' Has been asked.
For explanation:- Once the biases have been set they counter force all gravity in an envelope surrounding the ship. Without any gravity, at all, the ship is no longer a part of physics of the observable universe and has become dark matter. Dark matter itself contains no horizons, therefore, in dark matter you are anywhere and everywhere simultaneously !
Why Dark Matter Transit
Well to put it frankly, we know nothing about dark matter at all, but we know from Einstein that time travel, warp drive, hyperdrive could not work. The other alternative for space travel offered is worm holes but even if they did exist would they be stable enough to journey safely from one point in space to another and then back to the original departure point ?
So lets examine them one by one, starting with:[
Time travel, as Einstein has pointed out, nothing can move faster than light, and what would be the propulsion method. Light travels at over six hundred and seventy, million miles per hour. Obviously the human frame would never, permit one to accelerate from zero to that speed in seconds or even days. Maybe after a steady fuel burn for a couple of years you could possibly approach the speed of light. Albeit, one would imagine you would need a moon sized fuel tank along with you. Moreover, even light speed it pretty slow in terms of the universe. So that all seems a bit of a non-starter to me.
Warp-drive and Hype-rdrive, what are they and what do they burn for fuel ? What Sci-Fi hardly ever tells you is that if you set out on just such a voyage you would be aiming at a point of space where the picture you see, today, represents as it was, a few thousand years ago. Worse still,, you would have no forward sensors and you would be flying blind. Space itself contains debris which would often be so small that it could not be seen - except in close up. Regrettably If you were to hit something even the size of a pebble at those sort of speeds, it would probably vaporise your entire space ship.. Also, at full speed: to have time and distance to take avoiding action you would need to be aware of those orphaned pieces of rock up to about 100,000,000 miles ahead of you . You couldn't use radar !
Worm holes !Tthe universe is anything but stable, in fact everything in it is moving, thus the focus point of a worm hole will move, too, one minute pointing at one part of the universe and in another hour it could be pointing at an entirely different area of space. That could be a billion years in the future, or maybe never, again aligned exactly in the same. direction . In consequence, if they exist at all, one may be able to use one to arrive at their intended destination, but it would sheer luck if you could use it to come back !
This brings us to dark matter, for the purpose of these books, and not disproven any anywhere, dark matter is the fundamental universe. It is the only constant across all universes, it is in everything and between everything. As it is universal in limitless space, it has no measurements. Travel in Dark Matter takes you outside of the physical universe so that space hazards do not exist, indeed, you may even pass through blaziing stars but be unaware of them in your journey for which you will have previously keyed in your planned destination, at which you will arrive in less than one second.DMYas it is out-with the constraints of our known physics they do not apply.
See you out there !
How is a local universe created. In my opinion a dying universe is, over a period of billions of years, sucked in by gravity into a black hole. Eventually when the black hole has consumed a whole galaxy, or more (including any other minor black holes in its territory) it reaches critical compression and explodes and a new local universe is born. The physics of that new local universe are created at the moment of the explosion and are not necessarily the same physics which we could recognise
The human mind has a problem, it cannot imagine limitless. There has to be a barrier or a horizon or an event. Even learned professors discussing space seem to be uncomfortable with that and they speak of the universe as if it were finite . But is that true ? Limitless means it will never end regardless of which direction you take. The same with physics, we know the physics applicable to near space. It does not follow when you use the term 'limitless' that the physics we know will be the same everywhere, but here again the human mind will not permit us to speculate . To us everything has length, breadth, and width, or we can touch it, hear it, or see it. If it fails to fall into any of those categories it cannot exist ….or can it ?
