hello lads, so I am interested in this point. Would weed help stop cancer just as good as chemotherapy. Also if you had cancer would you take chemotherapy or not? Finally, does weed actually help prevent/stop cancer?

ty in advance, btw non pic related, idek what this pic is doing on my pc anyways

no, chemotherapy wrecks the shit out of cells, there's nothing in weed that does that.
>Also if you had cancer would you take chemotherapy or not?
depends, it's probably a good idea
>Finally, does weed actually help prevent/stop cancer?
I'm gonna go with most likely not, smoking it definitely no, it'll probably make you get cancer faster.

Imaginary time allows you to make sense of time "before" the big bang, time within black holes, quantum wave-particle duality, and many other things.
Why have people not adopted the use of i time in physics?

I'm pretty sure it doesn't.

No. In that case you'd be viewing a different plane of the third dimension as it intersects the fourth.

https://www.nasa.gov/feature/promising-worlds-found-around-nearby-ultra-cool-dwarf-star/

I only heard about this on the news recently and they were all "best place to look for life" but then

>Although they orbit very close to their host dwarf star, the inner two planets only receive four times and twice, respectively, the amount of radiation received by the Earth, because their star is much fainter than the Sun. That puts them closer to the star than the so-called habitable zone for this system, defined as having surface temperatures where liquid water can exist, although it is still possible that they possess potentially habitable regions on their surfaces. The third, outer, planet’s orbit is not yet well known, but it probably receives less radiation than the Earth does, but maybe still enough to lie within the habitable zone.

Which doesn't sound anywhere near as promising. Am I right in assuming this system is important because the planets are earth-sized and within roughly the right area and therefore other systems might be similar, or is there really any chance for life to develop on them?

>>8049312
>for life to develop
No, it's way too hot for that.

But it's nice because it's a dwarf star. That'll be very useful to us in a couple billion years because dwarf stars burn extremely slowly. If we can find any way to inhabit it at all, we'll have a home for a very, very long time.

Personally I favor gravitational nudging into the habitable zone. We have billions of years to get it right, so there's virtually no way to fail.

>>8049312
being habitable is just the beginning, they need loads of water and carbon and all that other shit that only Earth has

How do I read faster without sacrificing comprehension? I can feel myself subvocalizing when I read, and my eye sometimes gets stuck on a word for a fraction of a second, which is annoying. I read faster than most folks, but I'd like to improve.

Put finger on page, trace the words you are reading.
Speed up the tracing until you can't keep up.

What also works is reading everything extremely quickly and multiple times

Please excuse my shameful ignorance, but this is something I've always wondered:

The set of all real numbers is infinite.
The set of all prime numbers is also infinite.
Yet the set of all prime numbers is a subset of the set of all real numbers.

But how can there be more real numbers than prime numbers if there are an infinite number of both of them?

>more
There aren't more. More implies a quantity. We're not dealing with quantities, we're dealing with set cardinality. The basic premise is the one grows an infinite ratio faster than the other.

What are mathematicians trying to accomplish using stuff like using Calabi-Yau manifolds, let alone discovering them?

It seems to me you are just making things /extremely/ and needlessly complicated.

I'm beginning to think all this is just a competition to prove how much you "know" (regardless if that knowledge is just a complication) and a way to give yourself an excuse to find problems which have really no bearing on reality.

You cannot honestly tell me that these "manifolds" do or mean anything. Please don't tell me this "in some universe maybe beyond this one." No. You are just making everything complicated.

Assume the axiom of infinite. You now have a valid system for saying two infinite sets have different cardinality.

You can also assume the logical opposite and the logic will still work.

>>8048804
So, in theory, one could assume that literally every conceivable thing exists, due to the nature of infinity?
