TL;DR: generation of high power microwaves from organic mechanisms is very, very hard and evolutionarily unlikely. Microwaves are also a terrible way of tunnelling through ice. Note that polar bears and leopard seals don't bother in the real world; who are you to argue with those highly effective apex predators? As another answer already touches on the ...

While it's imaginable that an organ could evolve to emit low-powered microwaves, this is not a practical way of tunnelling through ice. Melting ice - changing it from solid to liquid without substantially altering its temperature - takes a lot of energy. According to Wikipedia, enough energy to raise the temperature of an equal mass of water by 80°C. You ...

Hydrogen peroxide is used as rocket fuel, so this planet would definitely be unstable. It is very good at causing reactions and is very bad for life. If it was less than 5% Peroxide, maybe, but UV also causes it to break down into water and hydrogen, so unless your creatures were actively putting it back into the water, it would most likely disappear in a ...

My first answer on this site, here goes... I used to dabble in microbiology, and at first I dismissed your question as simply impossible. However it kept me thinking, and I came up with a chain of events. Viruses 101 We have to remember that viruses are tiny and very very simple. They each have their tiny bit of genetic code, a capsule of some type and a ...

Plants make glass Stinging nettle, ocean sponges and other plants produce glass. Nettles make their needles from it and sponges make their skeleton. These glasses made by plants are called "phytoliths", from the Greek "phytos", a "plant", and "lith", a "stone". See Plants make glass If silicon is already being used in lifeforms, the carbon and hydrogen is ...

Intelligence and Knowledge are Weapons. Silicon carbide is a ceramic often used in vehicle and body armor, but could a living creature produce and use it the same way? Yes. They're called "hu-mans". They may not be very attractive, but they're smart. What they lack in beautifully colored fur or feathers, they make up for by wearing sacks and painting ...

This Nature article reports on electrochemcially producing silicon carbide in molten salt at 900°C. That's still pretty hot for the typical biological life form. Still, if the life form had an internal crucible made of silicon carbide, it is vaguely conceivable it could support a solution at 900°C. This article from the U.S. Department of Energy Office of ...

Our consciousness is dependent on the communications between our neurons. Reasoning from that, you need your viruses to communicate. Since there isn't a fast channel available in reality, maybe you can invent one. It's very far fetched to imagine an artificial neuron network (ANN) or natural neuron network (NNN) forming in that higher dimension space, ...

There's an issue with the question. You assume consciousness is a biology defined term. It's not. It is a philosophy term. Thinking of it biologically is what's giving you the trouble. Let's talk biology first Viruses infecting brains is not common, but it's certainly not rare. Viruses mutating quickly is what they're known for. Viruses hopping species ...

Viruses cannot achieve consciousness as we know it because they do not communicate among themselves. In the briefest terms, a virus is a piece of dna inside a microscopic capsule. The capsule has protheins that allow the viral DNA to enter cells and hijack their prothein producing mechanisms, but that's it. Therefore a virus can only be as intelligent as ...

Probably breathable but almost certainly dangerous: The recommended 8 hour Ozone exposure is at most 0.1ppm, that's a thousandth of your atmospheric concentration. Given that studies have shown that tiny increases of just 0.001ppm cause notable increases in fatalities this is almost certainly a sizeable problem in a continuous exposure scenario. The other ...

As for the breathability of the atmosphere. I encountered this list in a video by worldbuilding YouTuber Artifexian and have added to it since. I did check several values and found them to be correct. Going down the list it became increasingly difficult to verify the values, so take everything without a link with a grain of salt. N2 < 3 atm 1.25 atm, o....

I have not done the maths, but using common sense and some research I have got you an answer. At 5% oxygen concentration on earth, with one bar of pressure, you start to die, although with 1.5 bars of pressure you would definitely survive. It seems (at least with my understanding) that with a 5.5% percent concentration of oxygen would act like 8.5% ...

What matters for breathability is the partial pressure of the gas. According to Dalton law $Partial\ Pressure = Total \ Pressure \cdot volume \ fraction$ For Earth $P_{O_2}=1 [bar]\cdot 0.21=0.21 \ bar$ On your planet $P_{O_2}=1.5 [bar] \cdot 0.055=0.08 \ bar$ That's a tad more than the partial pressure in the Death Zone on Mount Everest at the ...

Depending on how these portals work, you could make some portals under sea level so water would spew over the desert ground. If the volume of water was great enough to beat the rate of evaporation and soil drainage or if you had built some rocky substrate to prevent some drainage, you'd get a neat saltwater river, lake or, better yet, cannal system. Around ...

Bring soil. In the real world, fertilizer / soil amendments are nice because you do not need to transport as much mass from where it starts to wherever your farm is. If your people have portals, transportation becomes much less problematic. Just bring soil from a place that has nice fertile soil, like a steppe or prairie or river valley. Put that on top ...

Yes, peat, water and nitrogen fertilizer will go a very long way to making nearly any kind of desert land bloom even without the rest. As a comment noted, it's a lot easier if you start with an arid area having some sort of soil rather than nothing but sand, but its doable in either case. The first thing to remember is that organic matter is not needed -- ...

Strictly science based - what you need is advanced genetic and embryonic engineering capabilities. Your average human isn't going to develop the way you want, so you're going to have to modify the template. Of course, you can start with a human template as close as possible, which will probably not be as strong or as dumb as seems to be required. So, ...

Your "cold Haber process" already exists--it's what nitrogen-fixing bacteria do on Earth! The ammonia generated by that process is then further transformed into nitrites and nitrates, with all three forms of bound nitrogen being used in various ways in terrestrial biology to build more complex molecules. This is an energy-intensive process for Earthlings, ...
