Anyone legit into AstroPhysics?

I'm not legit into it but - learned the basics of space-time in school, in actual physics class, and now peruse occasional youtube vids at my leisure.

Crazy - some of the shit.
The main channel (which is fucking massive, with millions of hits), is, I think PBS space time.

These dudes explain how, leading physicists, via mathematics, can actually calculate historical and future solar/cosmic patterns - including the onset of the fucking ice age.
They then confirm their calculations via a variety of means, depending on the specific subject but - relative to the ice age - by taking "cores" out of the arctic landscape, and sediment cores, out the ocean.

According to their mathematics and proven science - over the course of tens to hundreds of thousands of years - the earth exists more so in a glacial (covered with fucking ice) state, to a much higher frequency than it is now.

So - the only reason humanity has managed to flourish to the extent it currently has - is cause of some huge outlier in the typical rotation of earth around sun, but also, Jupiter around the sun - which has allowed the temperature to basically remain habitable for us - and thus the time for technology to flourish.

Via our technology - CO2 emissions have risen - and this is highly likely to impact the the degree to which the next glacial phase may effectively - freeze us the fuck over.
In other words - our higher CO2 emissions, are kind of, stopping us from become human popsicles - or should do, over the next 10,000 years.


Does anyone legit follow this shit??

I'm not educated in the field of AS but love reading about it and wonder what the next advancement will be. We could possibly get enough of an understanding of Gravity / Space / Time to manipulate Gravity / Space / Time in ways that people have imagined for years. Seeing practical research and new scientific findings that broaden my understanding of this Universe fascinates me.
 
I've wondered if maybe mother nature(or Aliens?) made us this smart and gave us the ability to work with fire specifically for the purpose of warming the planet up from perpetual ice ages. Is there a theory like that somewhere? It is weird that we are the only species on this planet that can make fire right? And our monkey instincts led to us putting all this carbon monoxide into the atmosphere, maybe it was all part of some grand design?

But I think astrophysics has less to do with stuff like that and more to do with stars, they break their light up into a spectrum and get temperature measurements from each of the colors emitted from that spectrum and somehow with that they can calculate their age/distance from Earth? Isn't that what Astrophysics is? I don't know.
No because warming is what brings on an ice age.

I quite enjoy it, not as excited as I used to be about it as nothing really astounds or surprises me anymore. I have several books on the subject, hell I had a poster with various major star sizes right next to my bed as a kid (which made the "Your mom" jokes with the relative sizes of celestial bodies all the funnier to me). I'm more interested in the fundamental structure of the universe or multiverse or whatnot and new discoveries that change the way we view the cosmos.
 
My degree is actually in astronomy but I've forgotten almost all of it. :(
 
I may or may not spend multiple hours at a time contemplating the nature of reality. Even though I am not traditionally educated in the field.
 
Since I was a little boy. I love all kinds of nerdy shit, but that's my main thing. More into theoretical physics though.
 
It's interesting, but it's also kind of depressing.

Kind of an interesting idea, but if they have the technology to make us smart, wouldn't it be easier for them to warm the planet up than give us fire as cavemen and hope we warm it up after a half million years or so?
 
PBS Spacetime is a great channel, I love that shit. Have learned a lot from it.

No, that's not what astrophysics is.
 
I have no shame in admitting that shit is way over my head
 
i am a huge fan of pbs space time and cosmos but the nitty gritty of it all I have never actually gotten into
 
If you're referring to basic mathematical principles or the derivation of E=mc2 as being "made up metaphysics" and having "no bearing on reality" - then you need to get some Cialis, pronto.

And I AM an actual engineer.
No you aren't lol.
