There are always people who are entangled in the problem of gravity distribution, and I have to answer it every time, and I have a headache, so I simply post a post to explain it. Pen "Fun" Pavilion www.biquge.info

One, don't use a model of a sphere with uniform density to set the randt star in this book.

Because first of all, the density distribution of planets is uneven, and in the case of the Earth, the density of the Earth's core is almost several times that of the Earth's crust.

Secondly, Rand is a saucer-shaped planet (a thicker saucer, a bit like a hamburger).

Generally speaking, a hamburger-shaped planet with an extremely dense core, the gravity of the poles is higher than the equator, and I will not list the specific formula, which is very rudimentary Newtonian mechanics.

Second, the centrifugal effect of planetary autobiography will reduce the gravitational acceleration beyond the poles, further increasing the gravitational difference.

Third, M theory, the strong force, weak force, gravitational force, electromagnetic force four forces unity.

In the high-dimensional space, the magic net can convert gravity into electromagnetic force (the magic net is a four-dimensional electromagnetic network with the equatorial ring as the base station), therefore, the gravity environment is completely different from the Beiluo cliff with a drop of 70 kilometers, which is caused by the radiation attenuation of the magic network.

Four, dozens of kilometers of straight cliffs, the Forgotten Sea blocked by Middle-earth, these landforms that obviously cannot be caused by nature, have been suggesting that this planet is not a natural product.

Some things that seem incomprehensible in a low-dimensional space are easy to do in a high-dimensional space.

For example, if we poke a paper clip into a soap bubble (assuming that the bubble will not be punctured, of course), the two-dimensional life on the bubble film will see three or four independent but rigidly connected metal patches, which obviously does not conform to the intuition of the soap bubble person.

In the prequel "Lock the Starry Sky", it has been hinted that because earthlings live in a starlock, their worldview is narrow, just like soap bubble people.

ps, a few more words about the magic web.

The magic net is an energy base station system first created by the Divine Second Magic Empire, and the energy of the magic net can be called at any time within the base station range with a quantum interpreter, but this is only the ultimate form of the magic net.

The original prototype of the magic network was two, the biological brain network (BRinternet) and the wireless power transmission network. Both have developed to an extremely high level, and then merged into one to develop into a magic net.

What is Shenhai? It is the interface where the local quantum states of the human brain are embedded in the magic web.

This interface is the port interface of the Magic Net interpreter, and it is also the stand-alone interface of the BraInternet (Brain Network).

Extraneous topic: The emergence of braInternet is the product of the extremely high level of Internet technology, quantum physics and biotechnology.

When technology develops above the Fourth Civilization stage, it takes an extremely long time for an individual to learn a single domain (as is the case in the Base series), so without a technology similar to BraInternet, it is almost impossible for a civilization to break through the self-destruction wall at the end of the Fourth Civilization.

So the magic model is the surface API of the magic web interpreter.

Regarding the quantum state of human beings, Da Liu's three-body problem and ball lightning are described, and a situation of local quantization of organs (Shenhai is the high-dimensional quantum state part of the brain) is imagined in this book. The light magic in the book is also related to this.

In the end, the Rand Star is indeed a flying machine...... It was neither the Holy Second Magic Empire nor the Magic Web that created it, it was a story related to the origins of humanity
