This reminds me of the almost tech, Brussard's ramjet. Cast a magnetic net forward to concentrate interstellar hydrogen for fuel and spew it from the back. Similar to ion propulsion. This and lightsail can be combined to ferry cargo to the next star, if we really had a reason and could stand the relativistic waiting.

Just a side note ... It is funny how the faster the jet the less complicated the design is. The largest factor is being able to compress the incoming air. at low speeds like regular jets you need to manually compress it. ram jets divert the high flow to create compression. scram just basically lets it flow through.


Jet gas-turbine


Ramjet<< mach 3-6


Scramjet <<< Mach-12-24

Right, then it would be a magnetic SCRAM. I think this author Larry Niven's idea.

IAC, space compression. Rather than paper, how about the idea of perm-press silk instead? No compression can last free from the forces that compressed it. What I really like about the compression idea, is that we can have model where compression doesn't propagate but merely relaxes. And we don't have to propose that we are in anything but the relaxed state. It is perhaps such that Entropy is to un-compress space and there is a smooth gradation in time from the totally compressed, Big Bang, till the smooth state we live in.

We still have to wonder the usual stuff. Why do we seem to be so maddeningly in the center so that we can't detect the edge?

OK, so, what if we are thinking inside out? Smooth space is the giant vast center, but by detecting the microwave background 360/360 we are seeing the shell of super dense space that is decompressing and smoothing itself. Indeed Red Shifted from the vast distance and acceleration.

It might be moving so fast that we are lucky to see the glow before it outruns the speed of light. So, whatever temp we surmise for the BB so long ago could be the actual temp of the wall of decompressing space, right NOW. Just barely detectable, and maybe not for much longer.

My counter argument to "No compression can last free from the forces that compressed it." If you tie a not dose it not stay even though you stop applying forces.? It dose because it can now pull on its self. If space can be distorted by huge forces why could this not happen as well. Remember compression is also a relative idea. It is potential energy with respect to a certain datum

So photon energy lvls would just be how many electrons are stacked behind it.? The light spectrum is just how dense the photon is since they all travel at the same speed yet some have more energy. makes sense i guess

OK, say a knot in the silk is a black hole? Some knots also remain from the early 1D epoch, as the 11D construct we mathematically visualize today.

A vast quantity of knots of space are the quantum strings. And at a certain view, ours, the knot we call 3D Reality has been unrolled, as it were, from the hot dense shell of space that is yet unraveling at the edges of the universe. We are iinside it. Very difficult to un-do these knots. Un-imaginable. But, compress the space membrane? I think so.

In the smooth space, center of the Universe, quite cool and nice, 4D space, (the silk or paper or membrane) is compressible. All matter and Gravity Waves, act to shoulder aside space, the energy transfer gives matter apparent gravity and can bend the course of photons. Make virtual mass, compresses space, release space like a rubber band behind for propulsion.

I like it.

So, any ideas on the math of space compression? To me it is a more plausible explanation for Dark Energy. What we are detecting is possibly a space density gradient?? I still feel very cobwebby about the structure of the universe. The common explanation is we are in the skin of an expanding balloon of 4D called space-time, but where is the center? As I've mused in other posts, the current thinking does not define an existent center, but that is central to BBtheory.

If, however, we are inside the expanding dense shell of solid space, the part that has become relatively cool and empty, that makes more sense to me. There is a center, because here we are. It exists. We are inside and everywhere we look is cobwebby space condensation. Matter, fairly uniform on that level. As we look farther we see space becoming more solid and only quasar and pulsars are beginning to splatter out, "farther" still only the microwave background.

Now we need the math. I read that the Earth is moving at 18.5 miles per second in orbit. One could postulate there is a density gradient fore and aft of the orbit path.

Is Time a Dimension?

Many are familiar with the Flatlander thought puzzle. And there are math models for the next level 4 dimensions....the hypercube, for example.

But, thinking about it, dimensions have certain properties, start w/1D. You can have: 1 position, 2 vectors and variety of velocity. Same with the other, higher dimensions, 2D, 3D. Not so Entropy.(time) We can only have 1 position, 1 vector, 1 velocity. Probably not a dimension, right? No freedom of velocity, even.

But, there is a 4th dimension that satisfies the requirements. It's the dimension this 3D universe sits in. Sometimes called the Bulk.

Maybe 5D is the Heisenberg. Non-locality of energy particles. Can't have position, vector and velocity all at once. 2 out of 3.

Maybe 6D is 1 out of 3.

7D is the other of 3,

8D another just one of 3.

9D - the locality pairs

10D - causality pairs

11D - to help us....to find.....GOD...(Moody Blues) Or as I call IT. Super-Consciousness!

Here is a mathematical model for Space as the basis of Matter.
