you know how people try to speculate about hypothetical biochemistries that could exist on other places in the universe?

do people do that with other stuff besides life? as in speculate about other thingts that could happen under certain circumstances and billions of years.

for example, planet clusters where a bunch of planets touch each other and don't break apart, becoming big enough to allow for small stars to orbit them

It's generally referred to as "scifi". Reddit scificoncepts and places like stackexchange often are good resources for such discussions

I think it's been proven that the laws of physics are the same everywhere in the universe, precisely because they're laws, it's mathematical. Maybe not at the very beginning of its existence.

As for biology, there are no laws of biology (or maybe we haven't discovered them yet) and the only example of life we know of is on Earth. And so far, all life has come from the same common ancestor. That's why, when we look for life elsewhere than on Earth, we can only look for the same type of life, a cell or composed of cells, but perhaps there's life elsewhere that isn't cellular. But by definition, it's impossible to imagine.

most people don't realize how rare life on this planet is.
>plate tectonics is only .2 to .002% likely
>the chance of the moon being distanced relative to the sun and us
>our orbits are relatively stable
>the sun emits the exact temperatures needed to sustain life
>the tides create the exact kinetics to help generate weather
>basically life should never have existed at the statistical level
>oort cloud
>can't find planet 9 or whatever
physicists are delusional when they say that life is likely in other places lol.

The so-called "laws" of physics are nothing more than a model that explains observations we can make.
They are not "laws", because they're not real.

They are, as you pointed out, mathematics.

Physicists are often conflating the Goldilocks zone with life possibility. They are retards because even our moon is in the Goldilocks zone

How do you think that life could exist outside the goldilocks zone? I guess radioactive decay would work but radioactive material is fairly rare in the universe

I think there's a floating ocean somewhere in space

Biology runs on the laws of chemistry, which runs on the laws of physics. All chemical machinery is required to have atoms which can arrange themselves in long chains. There are only 2 elements on the periodic table enough which have sp3 hybridization, and those are carbon and silicon. Silicon based life is impossible since a Si-Si bond is far weaker than C-C. Thus, only carbon based self-replicating molecules can exist. As a result, only carbon based life forms are possible.

Define life and being alive

It probably could not, but being in the Goldilocks zone is far from being a sufficient condition for life existence

There are many different arguments over what can be classified as alive or not. However, I think we all can agree that in order for something to be alive, it should be able to reproduce, or at the very least make copies of itself. The very first life on earth was chemical machines which could replicate itself. The only way for that to happen is with molecules containing long chains of atoms. Which goes back to my original point: that narrows down our building blocks for life to 2 options: carbon and silicon. And carbon is superior to silicon due to C-C bonds being far stronger than Si-Si bonds due to coulomb's law.

wtf is sp3 hybridization and why is that important enough to be a requirement for life in your view
