Lec 6 | MIT 8.224 Exploring Black Holes

Strange remarks on this video once more.

[SarahStarmer]

A lot of this lecture series wasn't as entertaining as television science programs but

they kept doing something unique and different and worth while they kept saying "We don't know the answer." or "There are a number of conflicting opinions".

and that's what science really is an exercise in applied doubt.

What happens when our universe has expanded enough to reach the lowest possible temperature? Must it stop expanding, or does temperature just bottom out and stay that way?

[delysid111]

Really.. I think we can get a glimpse of eternity. As all in nature scales of fractals up and down. The tornado in a bathtub is very alike the huge whirlwinds, and also the conception of a black hole. The dimensions are all related. The origin of the universe is impossible to concieve without knowing the forces that create the particle. To me these things seems the same. The Background Radiation might as well be the ending signal, of a continous flow of particles disposed in the outer reaches.

Too bad they don't allow video responses, I would post the video called "god m-theory genesis matrix". BTW he says there's a fashion dynamic to theory acceptance. The weakness of the gravitation models should stop the critics of the electric universe proponents. What we call the universe is a cavitation in the infinite dimensional. The retreat horizon is leaving behind our 4 dimensions and is probably causing expansion. It's not possible to find origins within our limited dimensions.

@seanmPWH I can dig it.

There is no beginning or end, there is no time. These aberrations are merely a result of biological interference of non biological phenomenon. So what we're left with is a series of parallel associated events which we define through matter, space-time, electrodynamics. Due to our biology we are prone to define, or think about the universe through the lens of our own consciousness. 

[BigMTBrain]

@pishdad - "There is no beginning or end, there is no time." Nice words, nice philosophy, but where's your evidence? That's quite similar to declaring that there is no mind, only brain. I would argue that just like the mind, while not a physical entity, is a real phenomenon that is emergent from physical interactions of the brain. Likewise, there is more evidence for time being emergent from physical processes than not... regardless of whether minds are present to observe or not.

[pishdad]

@BigMTBrain Wow! Ha, ha, ha, ha, Look at you. I'm sorry you're so deluded- "Big Brain." God, I shouldn't even dignify someone w/ your hubris by responding but I can't resist slapping bitches like you around some.You need a big slice of humble pie "Big Brain," which is of course the opposite of what you are. Digit brain propeller heads who pick names like that ALWAYS are the opposite of the pompous idiotic names created to psychologically over compensate for what they aren't.

[pishdad]

@BigMTBrain God!! Your paragraph is so full of holes I'm not even going to dignify it w/ an address. It would even make Swiss cheese laugh at you!! I'm just going to let you stew in total ignorance for the rest of your life. That's my punishment to the likes of fools like you. I'm sentencing you to eternal ignorant damnation. OMFG! If people didn't have such f'ing hubris I'd bother to help them.

[BigMTBrain]

@pishdad - :D And, no... I'm not laughing with you, but... Ha ha... the only holes are the holes in your arrogant "I make absolute declarations with absolutely no proof" mind. U B FUNNY!! :D

BTW, Big EMPTY Brain: I'm specifically belittling myself by saying that, no matter how much I fill my mind with real (non-PISSdaddy) information, it's always hungry for more, unlike yours which is obviously full of crap. Open that thing up dude, and let it air out! Whew! It's so foul in there. Yeeesh! :P

[BigMTBrain]

@pishdad - (part 2) - "These aberrations are merely a result of biological interference of non biological phenomenon. So what we're left with is a series of parallel associated events which we define through matter, space-time, electrodynamics"

Ha ha. That's some wicked funny religion ya got goin' on there. Stop trying to spread your new-age crap. Throwing out words that you don't even know the meaning of does not make you look smart; it simply let's everyone know that you're DUMB! :D

[pishdad]

@BigMTBrain Well you certainly got the "empty" part right! You certainly are empty in the head. I'll prove it. I'm going to do something you'll never be able to do w/ me mostly because you don't have the intellect. First lets examine your statement, " "...That's quite similar to declaring that there is no mind, only brain. I would argue that just like the mind, while not a physical entity, is a real phenomenon that is emergent from physical interactions of the brain..." Can't get more stupid.!

First where's your proof of the existence of 'mind,' moron?! None! So mind doesn't exist- only brain

[BigMTBrain]

@pishdad - You've proven yourself superior. I'll never study "emergence" or "complex systems" ever again. I'll now embark on an endless campaign to have the corresponding Wikipedia pages and all books on these topics burned. I'll send letters to all world-renowned scientists and technologists whose insights and inventions hinge on these phenomenon that we THOUGHT described how the mind manifests from the complex collective workings of much simpler parts, and I'll tell them PISSdaddy knows best.

Why do we need the BigBang? Before matter took form. If it banged from a point, why is it uniform. The bigbang predicts a dougnut shape, with a hole in the middle. The BB theory more resembles a supernova initiating our galaxy. How can you measure the age of a hydrogen cloud? Atom components are continously being released from LowFreq M-Branes. Can it not be that inflation is related to dark matter. Dark energy is the power output, product or resonance of DM, also known vacuum energy. HiggsField

[robespierreyt]

why does he speak of a dawn of time, or a beginning of universe? Even if we believe that there was at some point a big-bang, there must have been something before that big-bang...what was that?

[TheJawsusNSexmanShow]

some theories say a big crunch. so the universe is constantly expanding and contracting like a wave.

[robespierreyt]

big-bang and big-crunch sound like synonims, don´t they?

why is there the need for an initial event, call it bang, crunch or whatever you like? what if that exists today is the same as what has always existed, just it has transformed, i.e. there is no beginning or end; everything has always existed and will always exist. 'Matter is neither created nor destroyed, it is only transformed'

[ogirv101]

The Big Crunch is only a hypothesis, and the idea of a contracting or oscillatory Universe was proven wrong by Hawkins, Ellis, and Penrose in the 1970's. I wouldn't put too much money into that idea.

[fingerboy18]

That's why it's a theory, not a theorem.

[pishdad]

@robespierreyt Perhaps a bigger bang?

Question. There is a "dipole" shift we see in the CMB due to the earth's velocity relative to the CMB. Does this shift match up with redshifts from other galaxies to give a consistant direction and magnitude for the earth/solar system velocity? Also, looking from the direction of the dipole, this solar system velocity is not entirely within the plane of the milky way. Does the entire milkyway share this velocity vector component?
