Have they proved the Higgs field exists or is it a concept that just makes a bunch of theories and math work out correctly but cannot currently be proven?

There's a good amount of experimental data for the existence of the Higgs field. It's not set in stone, but it seems like it exists and behaves (boringly) more or less like we expect it to.

Seriously. You guys should have taken quantum mechanics as an elective. The math wasn't bad (basic linear algebra and calc) and it was fucking awesome. I'm also pretty drunk right now, but to clarify quarks and leptons (like the electron) are very different and interact in very different ways. The quark example was just to illustrate how much energy there is in these systems compared to matter. We fucking measure the mass fundamental particles in electronvolts, which is both a unit of energy and mass cuz shit be crazy in quantum land.

Great episode. I knew they were able to determine the elements of distant objects from light but didn't understand how. Can't wait to see what else they cover. 8 episodes left and this shit better get picked up for more. Next episode is titled "Deeper, Deeper, Deeper Still", so we may get into more of the quantum physics mindfucks.

I like the shot of him standing next to the flowers right after he explained the spectrum. Looking at the image, in my mind I was piecing together why things are the colors they are and sure enough he started explaining exactly that. Nice job of spurring curiosity and immediately fulfilling it.

That is somewhat misleading if the course you are talking about is the same one at my university. Yes, the math required isn't any more complicated than linear algebra and calc 2, but you won't be able to simply take it as a student in CS or even as a math major without taking multiple other physics classes to get the notation straight if nothing else. You would struggle even as a heavy math major in those classes, let alone trying to "splash" into it as just some random science major.

Now an intro to quantum mechanics class that was aimed towards non-physics majors would be pretty badass. Did your university offer something like that?

Can we pass a bill to change our vocabulary to Amerigebra or Freedomahol? Not sure as a southerner I can be comfortable with all the evolution talk and now this shocker!

Was seriously a cool episode. Earlier this year NDT came to a university just north of us and the tickets for the main auditorium and the spill over remote view room sold out almost instantly, was sad... Never did check to see if the school put it online.

Sunday's episode was probably the most boring yet. It really didnt cover much of anything that was unknown to me. Hell, after the episode, my friend's 14 year old kid even commented how all of that was covered in science class when she was younger. Pretty fundamental basics.

Loved the previous episode with spectrum light observation to detect composition of distant bodies. Very cool stuff!

Historical stuff was new to me, the rest was old hat as well (again, unlike the previous episode that was largely new to me, and the other half was a deeper explanation of stuff I knew a LITTLE bit but didn't know why they operated [my father's photostability work involved TONS of spectroscopy so I used to read a bunch of his periodicals on spectroscopy when I was in high school] - understood the results and reading them not so much about WHY it worked that way) - but it was nice to refresh the memory on some stuff I'd known but had gotten rusty on like the neutron stuff - been so long I forgot their nature to pair up evenly with electrons - although I did know it previously.

Yeah, I barely remember any of this shit after not thinking about it for 20+ years (and let's be honest... not really having any interest in learning it then to begin with).

I had my mind blown at least 4 times watching this week's episode. Not some buzzfeed "this will BLOW YOUR MIND" hyperbolic shit; I'm talking legit mind blown

Of course I was also high as fuck, so that may be the reason

You have to read between the lines. What he said i took it as, we really don't know what happens inside a black hole. Our laws of physics completely break down inside the singularity, and scientifically there is nothing we can say that will hold true inside a black hole. Hence even wacky theories as "we are already inside a black hole", are as possible as anything. He had made the point over and over of, a good scientist first and foremost knows and admits what he doesn't know, and is hot afraid by it.

Science fact, We don't know what the f is inside a black hole, there might be giants for all we know.

I thought the universe inside a black hole theory was pretty cool for a minute and then I realized a glaring problem with it. For all their mystery, Black Holes are finite, they have a boundary. This would imply that the universe has a boundary.

Good episode, they touched on a lot of interesting stuff. Finally understood WHY there has to be a weak nuclear force to explain observed reactions of particles.

I forgot where I read it, but one idea has to do with the concept of universe "reproduction". The show briefly mused that our universe may be inside a blackhole, but the hypothesis/idea goes further in stating that our universe can reproduce by having physical laws which allow the formation of black holes, and inside those blackholes are created new universes, and so on and so forth. Only the universes that can foster the creation of blackholes can "pass on their DNA", as it were. Kind of a "mind blown" type of idea.

The laws of physics as best as we can tell them have no correlation from our universe to that which is inside of a black hole. Meaning it is theoretically possible to have a "bag of holding" black hole.

To make things even more complicated if our universe is just one existence inside of a black hole ofanotheruniverse it may be that the physics of our universe as we know them have no meaning whatsoever outside of our universe.

Doesn't change the fact that it creates a finite edge to our universe if it's encapsulated within a black hole.

I thought Sunday's episode on the atoms was the weakest so far. I was hoping for more space talk. Although I didn't know it took 10m years for protons to get from the center of the sun to the Earth. And on the cosmic scale that is only an afternoon.
