I don't think my head hurt this bad since I read "The number of the beast" by RAH. Only, the main characters had a device that let them travel in 6-dimentional space.

Great stuff Nuclearman. Got a few problems with it.

3. The timeless universe is actually on a extremely small scale compared to ours. Such that light years can be traveled by going meters.

If it is in small scale, what keeps ships from colliding, or jumps at the exact same time causing your exit target being off from the predicted if the shield protects you.

Personally, as implied above, I like the idea of 1 megajoule of jump energy (239 grams of TNT) allows for a light year of travel in our universe.

Would be nice if that was the case, but a current nuclear power plants rated at 1 GW, which means that if you just need to dump power that a standard nuclear power plant could product in a second into a jump field, you could travel 1000 light years. I'm pretty sure that antimatter reactors could product even more power. That being said, I think you are off by a few decimal places on the power joules need to jump a light year.

Would be nice if the fans could build the math of the Jump drive mechanics and add it to the site 🙂

@Apoc: That does seem to be the issue. The only solution I can think of is that the ship is also scaled down. However, somehow the energy isn't. I have to do some hand waving to explain how that works.

As for the energy, I suppose I didn't care to go into the details with how long the post already was. The reason can be summed up with inefficiency.

It's not 1 megajoule per light year, it's 1 megajoule for the first light year. I used that as the shuttles tend to make small jumps like that, so I'm really talking about jump shuttles there. The energy requirement goes by the square of the energy. So 5 light years is 25 megajoules and 1000 light years is 1 terajoules. As for why the energy requirements are millions of times less than they should be, it's because the drive is that inefficient. It's mostly because if you plug in 1 gigajoule (not too unreasonable) it requires megatons of TNT worth of energy for jumping 1000 light years and that seems high for what could be absorbed from the blast. So the value for the first light year is actually somewhere between 1 megajoule and 1000 megajoules. Thus in order for the superjump to be that far and it would have kept going for Ryk only knows how only, then whatever mechanism caused the superjump is also much more efficient than the current method. In this case, between 1,000 and 1,000,000 times, the transition effect absorbs that much of the energy and what little remains can be used for movement. So most of the energy pored into the fields from the ship is wasted. However, that's not the case if the energy comes from outside. A laser beam hitting the field at the moment of transition might then have a similar effect as the super jump. You can see similar reduction effects in layers of radiation shielding. It only takes 6 tenth-thicknesses of radiation shielding to reduce the amount of radiation by a million times. I imagine the other universe would have the same effect on the jump energy during transition.

Another possibility is that the more energy the more efficient the jump as it's easier to punch through to the timeless universe. This needed to explain the relatively high cost of short distance jumps. I suppose that could make the energy-distance equations lower order as well.

Ok you guys have got the "theory" of this beyond me. But I was thinking...

If you had the energy somehow. (Insert magic energy source say tap into a star or something)

Time does pass in the other universe inside the field correct? Just not outside it.

Could you not have a base that was located there inside a field. Talk about safe haven.

Probably not Frank.

While time may still exist within the field, that isn't the case outside of it. The way I see it, in the timeless universe, "time" passes instantly. Therefore, you can either only stay in the timeless universe for a instant or forever there should be no in-between. It would be best to avoid a the latter situation. This does apply for my theory and likely applies to Ryk's (assuming there's any major differences). It may be possible to keep shifting back into the timeless universe without movement before the star's effects become an issue, but that only works if the star's effects don't exist in the timeless universe, but they probably would.

Thats cool. Just thinking of a pocket universe type of thing.

Alright, after rereading your thoughts to it I can imagine now the the transition into the timeless Universe at small scale and a timeless move from A to B at some degree.

Would have two things to add.

1.) Towards the Energy consumption discussion.
In addition to the distance you probably would also have to consider/deduct your kinetic energy (mass (m) and velocity (v)) some how. Time ceases to exist and not mass (established due to attraction to Black holes). Additionally, even though one travels instantly from A to B, the current speed might also have an impact. Just Imagine you travel at the speed of light and want to jump forward exactly one light year from your current position. Hence you are already moving with high velocity to the desired distance towards the destination wouldn't less energy required to keep the shields for the transition from A to B?

If on the other side only the vector is of importance, then the best battle speed would be 0 in order to quickly change the direction of the jump by micro vector changes into any direction.

Therefore the question: E = D^2-(1/2m*v^2) ?

2.) The Path from A to B
There still is the problem of dust particles and micro asteroids, hence a clear Jump path is required.
Would you imagine the ship to plough them aside or go right through them and the shields therefore disassemble the matter into their basic building blocks and dash the leftover aside as radiation? In any case, it would both be a give away that some one just jumped past a certain line, if suddenly space behaves oddly (for instance a pressure or radiation wave along a straight line). Or anyone ... another Idea ?

---

Regarding the Base (Trapped in the 3rd Dimension without movement).
Leaving the energy requirements outside - as soon as it makes the transition without return to the 4th dimension, I would as well imagine it to be trapped in the past and stay there at this particular point in time and space forever, with the only way to accessing it by time travelling to the inside of its Bubble. Better park it in a void between the Stars. With the vastness of the universe and the distance between the Stars there would be hardly any chance of some one finding it. (Which might turn out to be a problem with finding the Battle platforms as well afterwards)

True enough, the kinetic energy is equivalent to electrical energy in terms of units. It's not clear though if the jump drive allows for changing the kinetic energy. For example, when the falcon jumps to just above the surface of a planet. Does it's velocity relative to the planet change?

It's pretty iffy as to if it could be done, but it might be possible to do some interesting energy conversions in the timeless universe. Kinetic energy could be used to increase distance traveled at a cost of arriving with a slower velocity. It may also be possible to use electrical energy to increase velocity on arrival. Although issues with the wasted energy from transition mean it would be much more efficient to reduce velocity than it would be to increase it. Under ideal conditions, the change in velocity would be roughly equal to the change in velocity that would result if the energy was used to increase/decease the ships velocity. Thus hours worth of acceleration could be done in an instant simply by storing the energy required to accelerate for hours. It seems difficult to make it work mathematically, but it might be possible to do the kinetic-electrical energy conversions without actually traveling any distance in the timeless universe. Allowing for a ship to appear to have increased/decreased it's velocity instantly. This could be rather useful in a number of tactical situations where there is a need to either greatly increase or greatly reduce velocity. It could also be useful for dodging missiles or projectiles.

As for the path from A to B. The only easy explanation is to remember that as Ryk stated in his explanation, that the field does maintain some contact to our universe. That contact likely prevents the ship from being stuck forever in the timeless universe. It seems like the field largely goes around matter at least until the density of matter is high enough for it to cause the field to collapse. I would imagine that the field is weakened as matter passes through the field although since that part of the field is not in the timeless universe, it likely does not affect how far the ship travels beyond what happens if the field fails completely. However, that also means that the field may collapse at any point from when the field first touches the object until the object is through the field. So the field might collapse just before the object, causing the ship to slam into it. It might collapse as the ship is passing through the object, and result in the object and the ship taking up the same place with bad results. If the ship is lucky, the field will collapse after the ship has passed through the object resulting in leaving the timeless universe early, but with a perhaps otherwise fine ship.

As for the base, your logic seems fine in that case. It would never leave the timeless universe, but time in our universe would also never pass for it. It would be forever lost in the instant that it jumped. That seems like fair logic for what would happen if the link to our universe is severed. With that link, it will always return to our universe, without it, it never will.

Very interesting dimension videos.
