partially incorrect (i think, sorry if im being an ass hat). a black hole is like a gravity well, i think that earth to mercury would be pulled in. also, the sun is too small to be a black hole, it would just become very cold, and die (a neutron star).

Nope, our sun would become a White Dwarf.
And if for whatever reason our sun did somehow become a Black Hole (which it can't...), we wouldn't be sucked in, not even Mercury would get sucked in, they'd orbit the same since the Black Hole has the same mass as the star it is formed from, sometimes even less mass since it is usually only the core that forms the Black Hole.
Everything that has mass has a gravity well. YOU have a gravity well, it's just so tiny it doesn't effect pretty much anything. The Black Hole has the same gravity well as the star it formed from.

Actually, I believe what bullet_sandwich meant was that if we were to replace the sun with a real naturally formed black hole (the gravitational force of which would be much, much higher than the sun's due to the increased mass gained from being formed from a larger star) then the increased force would overtake the current orbits and suck in the closest of the planets, and possibly some of the farther ones eventually.

...and really, even if that isn't what they meant, they did apologize preemptively for their inaccuracy.

It has been cut out, but in my original statement I said that if our sun was to form a black hole (which obviously it can't, I was being hypothetical...) then we would orbit the same.

I understand that if we compacted the sun into a black hole (impossibly), the mass would be the same and therefore the orbits would be maintained. It stands to reason that a gravitational well would not increase in force just because a change in shape had occurred, assuming the shape change did not add or remove mass from the object creating the well.

This, I understand, however I did not say that the sun created the black hole (which is, as you have pointed out many times before, impossible), I suggested that a real and possible black hole replace the sun.

So, in essence, I suggested that we take the sun, replace it with Betelgeuse, and then turn that giant into a black hole.

In that situation, would the planets closest not be pulled in, considering the increased force created by a black hole that is actually physically possible and not the tiny impossible thing the sun would never create?

I have a question : seeing that the mass remains the same, you wouldn't need to make Betelgeuse into a black hole for the planets to be pulled in then, no ?

Yes, However, the whole argument was about black holes, and really I was simply suggesting that we take a real and completely plausible black hole (such as the one which will eventually, or has already, taken the place of the Betelgeuse formerly known as a red supergiant {hypergiant?}) and put it where the sun is now, and then prove a point which doesn't exist, because I forgot who I was defending and why.

As a Type 1 Diabetic, I face all sorts of people who seem to think I am 'allergic to sugar' and wonder why I am not as big as a house. People seem to believe Type 1 diabetes is gained from the overindulgence of too much sugar, Where it is actually an auto-immune disease, a fluke basically. I was just curious what kinds of misconceptions the general public have about the escapist community's lives and how you deal with it. I'm also open to answer any questions you have about me and what daily life involves.

I think this one annoys me the most

"The belief that planes couldn't bring down the twin towers because jet feul doesn't burn hot enough to melt steel"

I think someone utterly missquoted that statement if you heard it that way. Though I have no idea how hot jet fuel burns or how hot it needs to get for a plane to evaporate, the way that statement was used by the 9/11 skeptics (that I read about anyway) is that the plane that crashed into the Pentagon had almost completely evaporate. Which is supposedly impossible because jet fuel doesn't burn that hot. That was their cue to bring in the "It was a bom of some description"-theory.


OT: The misconception I encounter most personally is the one where people like my mother and her parents think because I spend a lot of time on the computer that I must always be playing a (violent) game and I'm completely addicted to it. I study Webdesign.. Is it that impossible for me to be.. ionno, working for school, designing a site? Or even just fooling around in Photoshop due to boredom? Or watching a movie, talking to people? Nope, must be I'm gaming like an addict. /rage

No it's the idea that jet fuel can't burn hot enough to melt steel so the twin towers shouldn't have collapsed because the rest of the building would still have been sturdy

That's actually true, though misleading. Jet fuel does indeed not burn hot enough to melt steel. Steel melts at about 1400 degrees Celsius, and I think jet fuel burns at about 800. However, this is misleading because steel becomes soft when it heats up. Steel can lose half its tensile strength at a mere 600 degrees, so even though jet fuel fire wouldn't have melted the supports in the WTC, it would have weakened them enough to give way and collapse.

I'm not big on fighting games, but by the looks of it, the Haduken spam is to pressure your opponent into either:
A) Defending
B) Make an aggressive advance which leaves them open to counter attack
Am I close?

More or less. What they're doing is an aspect of "zoning", a technique meant to keep your opponent from being able to reach you and counterattack, while simultaneously keeping yourself in ideal attack position. Ryu, like most projectile characters in Street Fighter IV, has excellent zoning tools- the Hadouken is the original keep-away device, after all, and his almost-unbeatable Shoryuken uppercut discourages trying to get around them with risky jumps.

Now, Daigo and Alex have both been playing Street Fighter professionally for something close to twenty years. They're easily the best Ryu players in Japan and America, respectively. They are masters of their craft.... So naturally, watching them attempt to zone each other out is going to be explosive.

What they're doing looks simplistic, but it's actually a constant battle for the high ground, and as the match demonstrates, one false move can very easily lead to disaster.

i dont know why, but i love to be proven wrong. well, thank you, i guess you do learn something new every day!

I'm Canadian and I've seriously been asked if I live in an igloo. The sad part being I was asked this by someone who lives less than 300 km from the Canadian/American border, it's like they thought there was a magical line at the border where the temperature just drops 30 degrees.

The fact that im british i immediatley like tea.

The fact that i do and i make a fine brew is neither here nor there

When i become the supreme ruler of the world, i will decide if someone should be put to death by their tea making skills.

one thing that really bugs me is that because I went to university and got a degree, some people seem to assume I know EVERYTHING

Finally a way to deal with the weak milky tea makers of the world. You have my vote.

I have PTSD. People think I'm an asshole when I'm really having an anxiety attack. When I explain I'm having said anxiety attack, they feel they have to defend themselves. It never ends well, especially when I have to stash the corpses.

There's also a general misconception towards stereotypes. Look, just because I wear darker clothes, a hat and shades at all times, and I slouch when I walk doesn't mean I'm a drug addict. I'm just at a higher level than they are.

I was in accounting too, and there were a lot of people who I would have considered not having souls..

But the bigger accounting 'misconception' that I've come across is that if you study accounting, it means that you would be absolutely ecstatic to do the taxes of every person you've ever spent 5 minutes with.

Also a lot of people seem to think accountants are all geniuses in math, while most of the math we use is quite basic.

totally forgot about that one. I always say 'I don't use higher than mayyyybe grade 7 math. Accountants pay people to come up with computer programs if we need something more complicated'

Anything involving black holes. Sci-Fi have made them out as planet munching monsters that go around the universe eating stuff up. Also that they're some sort of rip in space-time.
If our sun was to turn into a black hole (It wouldn't, but follow me on this...) we would orbit in the same way we do now. We'd all die from the cold of space, but we'd still orbit it. It wouldn't suck in the solar system because IT HAS THE SAME MASS AS THE SUN. Gravity is caused by mass, and you can't create mass, so a black hole is only as heavy and powerful in terms of gravity as the star (Or core of the star...) it came from! And they aren't rips in space or whatever badly written TV shows have you believe. The event horizon, the black part you see (Or don't see, whatever way you look at it...) is just the radius at which the gravity is so strong light can't escape. It isn't a surface, but it definitely isn't some sort of inter-dimensional rift.
Also, that they 'eat up' time. No, time (Like energy and matter...) can't be destroyed or cast into some sort of void, it's just that according to the laws of general relativity the singularity at the center of the black hole has a gravity so strong that time essentially stops at that point. If you were somehow magically unaffected by gravity and you were somehow magically inside a singularity, if you somehow magically managed to GET OUT of the singularity, you'd be an infinite number of years into the future. Considering the universe itself is finite, you can understand the impossibility of exiting a singularity or even the radius at which light can't get out of a black hole.

partially incorrect (i think, sorry if im being an ass hat). a black hole is like a gravity well, i think that earth to mercury would be pulled in. also, the sun is too small to be a black hole, it would just become very cold, and die (a neutron star).

No, no it wouldn't. The black hole would have precisely the same mass as the Sun does now, so it would have precisely the same gravitational pull. A 'gravity well' is simply the area around an object in which that object's gravity is supreme. Everything in the solar system is in the Sun's gravitational well, much like we are in Earth's.
And yes, the sun is too small to become a black hole, but that wasn't the point he was making.

Just because my family lives in the "rich" part of town, doesn't mean I'm rich. We bought that house from my uncle. He gave us a great deal. Quit assuming that I get everything I want. Yes, I do get more then the average teen, but guess what? Everything I got, I've worked for it. Going to a tropical place? My grades MUST be about 85%, or they won't take me. Want an new console? I have to PAY FOR IT! Want a phone? I had to pay for half of it and guess what? I HAVE TO PAY FOR THE BILL!

It really pisses me off when people are all "Oh? Isn't your dad just going to buy it for you?" or "Please, you probably got it as a gift." No. It may be for some "rich" families, but not mine. Everything I have, is because I worked for it. I paid for it.

Woo, sorry. Lately a lot of my fellow classmates have been getting on my case about my family's income.

No, because Betelgeuse is larger than the "inner-circle" of our solar system. It's hypothetical black hole form would be large enough to reach past Jupiter outright. Our whole solar system would probably easily get sucked in. But your point is still correct, of course. Just slightly wrong in context
