An alternate Universe that behaves the same, but with easier to understand physics

Technobabble is Technobabble No, this model of the universe as a cellular automaton cannot be reconciled with the basic behavior of our real-life universe. Let's take a simple example, exploring a ...

Glass Trees - how feasible is it?

There are already creatures using silicates for their scaffolding, like the siliceous sponges The siliceous sponges form a major group of the phylum Porifera, consisting of classes Demospongiae and ...

An alternate Universe that behaves the same, but with easier to understand physics

Fundamentally no. Our model of physics is the simplest one we can pull off that explains as many of our our observations and experiments as we can. If a simpler model that would predict the results of ...

Glass Trees - how feasible is it?

There have been several silicon biochemistry questions this month. Why has it suddenly become more interesting? Whatever the reason, I'll skip stuff growing in the sea for now (L.Dutch already covered ...

An alternate Universe that behaves the same, but with easier to understand physics

You are trying to solve an unsolvable problem Any system of physics that fits a universe as complicated as ours cannot possibly be "easy to understand". Your system proves that point. (I got ...

Glass Trees - how feasible is it?

Many plants lay down silicon to augment their "skeletons". Horsetails have the most. No plants I know of need to build their bodies out of silicon lke the glass sponges do. But lots of ...

An alternate Universe that behaves the same, but with easier to understand physics

Frame challenge: Make late-19th century physics accurate Toward the end of the 19th century, there were several prominent physicists who thought we had figured out pretty much everything fundamental ...

Alt. Biochemistry - Which of these is a suitable alternative/mirror to DNA?

p-RNA So, caveating that I'm more of an evolutionary biologist than biochemist, and these days more of a programmer than either. One of the issues here is not making the things - I'd strongly believe ...

Need counters for a near perfect Anti Thermal and Kinetic armor system in a near future setting

Glue-ball guns. They should be a bit like regular paint-guns, lots of little balls as ammo, but when they hit, they foam-up and become sticky and rubbery. One wouldn't be much of an issue, just messy ...

Rassling Your superarmored soldiers are tough! Stuff that blows up ordinary soldiers will not blow them up. Bullets that perforate normal soldiers wont perforate them! I am not sure if their ...

Glass Trees - how feasible is it?

"I’m wondering if this or something similar can be done with a proper multicellular organism" Yes. If the question is limited to only silicates, then the issue is more challenging, although ...

Need counters for a near perfect Anti Thermal and Kinetic armor system in a near future setting

Kevlar stops bullets really well, but it's pretty useless at stopping a knife, because a knife doesn't twist and get fouled up by the Kevlar fibers. Likewise, your hard armor is great against energy ...

Need counters for a near perfect Anti Thermal and Kinetic armor system in a near future setting

Smart artillery/rocket sub-munitions. 2 (or more) part charges. The first charge is a large calibre (greater diameter and mass than a .50 bmg) slug, the sole purpose is to overwhelm the first layer of ...

Alt. Biochemistry - Which of these is a suitable alternative/mirror to DNA?

TL;DR: I suggest either GNA or PNA First, a couple comments on the alternatives: Regarding FANA: Very few fluorine compounds occur in nature and, as far as I know, almost all are produced by plants or ...

What would be the different climates of an island six time the size of Madagascar in longitude and latitude near the west of the Drake passage?

LATITUDE: The most obvious and simple influence on climate is latitude. At the 60th parallel south, you could expect freezing temperatures every day May-Sept, and some days almost every month. Here is ...

What would be the different climates of an island six time the size of Madagascar in longitude and latitude near the west of the Drake passage?

A land mass six times the latitude span and six times the longitude span as Madagascar would cover 21,340,800 square kilometers -- larger than Greenland, larger than Australia, larger than Europe, and ...

Alt. Biochemistry - Which of these is a suitable alternative/mirror to DNA?

DNA and RNA with additional letters dont need proteins at all. Protein folding acts as a catalyst and structural material. with additional letters rna can do this job. https://www.quantamagazine.org/...
