Rating: 4.0; Vote: 1
It's time for the end. At least the end of our first series on Physics here at Crash Course. In this episode of Crash Course Physics, Shini sits down to talk about Astrophysics and Cosmology. By using what we've learned this year, we can come to understandings about our universe. Understandings that open ideas to us to help us grasp how our universe works. Join us for this final episode of Crash Course Physics as we head into the final frontier. Crash Course Phsyics is produced in association with PBS Digital Studios.

What science can know and not know? Physics, -, earth, smart scientists, the way the world works, theorists, taboos, being careful about saying things, what we can say and what we can not, Bull$hi+! Fullstop - lying?
Fact! The physics of fluids dictate that liquids like water always find level, every time, without fail, everywhere one might test, regardless of the age or intelligence of the man woman or child to do it, without regard for the feelings of a lost baller in space. The only space that exists lies between us. Earth is Not Flat folks. That is an idiotic assertion! Words mean things. Yes, put them in a looney bin! Obviously there are many differing degrees of ground above and below the sea that is flat level! It is the - water surrounding all the land upon which we stand that is level like the sea.
No nonsense back! i am not a member of your filthy society or clubs. i don't want your insight or require your assistance. Toddlers who have - graduated from the sippy cup have demonstrated a fundamental understanding of the physics of fluids and you tell me science can't know this! Most of those toddlers, who obviously know more than the totality of the mental capability of knowledge and experience of mankind, many of those babies are still wetting the bed so i firmly assert, piss on scientist and anybody willing to suggest that we should be required to suffer them among us. They are as legions of parasites! No. i will not suffer them! Full -.

A new thought for common sense.
I think of gravity as this. Energy emitted from the sun instantly begins the rarefied process. Gravity is this process in reverse, energies negative byproduct. Through this frequency zones, if you will, are established.
By creation and use of the magnetosphere, a portion of the energy from the sun is centered at the earth's core. It is thereby emitted in the same fashion as the sun, at tolerable levels determined by earth.
If an individual were to think of this as a 1, 2, 3 rarefied process, the 1 would be the initial establishment of equilibrium at the core, providing orbital patterns. The 2, 3 would be the other portion we know as sun shine, from which wind and other earthy phenomena are explained.
From this thought, I have been able to explain the universe.

Lol it's called the big bang theory for a reason, because it's a THEORY lol, I like how everyone who is ignorant about the research into astrophysics claims the -theory- as fact, there is a higher chance of a monkey typing the dictionary word for word in one go randomly on a typewriter than the big bang occurring and ur saying that is science's #1 theory, even if you can explain the big bang which you can't even still, how did that ball of energy get there that exploded. Like I have no bias it's just sad that people run with this idea like it's Intelligent.

As a real physicist I must ask. The fact that 80% mass is missing. Doesn't anyone else wonder if there is a simple error. There appears to be a problem where Newton is OK is some places but general relativity is OK other places. Just saying.
I work in materials we have far better success --

Bird droppings were used for propellants also known as gun powder derrivative, I do not see what that has to do with them sticking an antenna in the air and discovering the -big bang-, but still great video! :-) Min 5: 54

In the history of cosmology, astrology and astrophysics there has never been 1 single viable hypothesis. It-s utter pseudoscience. No wonder the flat earthers are owning this debate.

I mean if scientists don't know anything about dark energy then why talk about it in absolute terms, as if there are things that can be predicted from its properties

Omg. my mind is BLOWN! I love astronomy and especially astrophysics! I have learnt so much from this episode alone! Keep up the great work Crash Course!

You know if we could rearrange the solar system we could rearange peoples personalitys. Is that why venus was plopped into the mix. Must be.

I'm afraid to die not because of dying but beacaus I will never see how far humanity will travel or what we will discover
