When will electrons fall into the nucleus?
Realitycheck replied to questionposter's topic in Quantum Theory
The size of an electron's orbit is about 20-150 thousand times greater than the diameter of the nucleus. Once you get to atomic numbers greater than 100, you start running into problems with the atoms being unstable and falling apart rather quickly. -
That would be pretty difficult to plant the charges ahead of time in the exact same floors where the planes hit.

Stephen Hawking retracted his paradoxical view
Realitycheck replied to G Anthony's topic in Astronomy and Cosmology
What do you mean "matter is crashing down to the center of gravity for all eternity"? It is plastered to other neutrons and electrons collapsed in an ultimately superdense heap. No disrespect intended. I mean, obviously, you seem fairly well on top of the subject, but it almost sounds like you're pushing 300 year old pushing gravity. -
The photons are absorbed by the retina, light-sensing nervous tissue, at the rear of your eyeball.

1/(1/0) is the same as 1*(0/1).

Unusual surface feature on dwarf planet Pluto

Meade 14" telescope with 60 second exposure. Looks like the remnant of a relatively recent meteor that remained embedded. Very interesting. -
Actually, tops was about 800 tons. Temple of Jupiter at Baalbeck, Lebanon. Raised onto a 30 foot platform with an earthen ramp, most likely, though they gave up on the thousand ton block and left it sticking halfway out of the quarry.

What is your justification for believing in a God?
Realitycheck replied to Realitycheck's topic in Religion
Here we go: According to Gallup poll, between 1987 to 2000, 20% of Americans reported to stop going to church, but 60% reported having a mystical experience. From a bit different perspective, in 2002, 80 million people reported having a "life-changing experience which changed their life around". With the economy in the dumps, I can see how that could contribute, though 9/11 was probably the biggest factor in that. To sum up what I was saying about miracles, the first report is quoted from a critique on a supposedly best-selling book called "A Course in Miracles", a modern spiritual self-help book. I wonder just how far out on the branch it takes you. My guess is that since its best selling, its probably pretty conservative. -

http://en.wikipedia.org/wiki/Pontifical_Academy_of_Sciences What can you say when they keep them all cooped up together, vowed to celibacy, but living amidst the dogma that everyone sins and everyone is forgiven? -

From what I've seen, Catholicism has made rather substantial efforts to bend into as much agreement with science as possible to keep up with the times, within reason conservatively, Pontifical Sciences and all. I'll find a link. -
Malwarebytes.com, though there are possibly a few other free ones that might be better. I'm seeing Mcafee as the most popular these days for a price.

Without knowing the exact specifications of inflation, a very questionable theory in itself, it is impossible to know.
-
I have to admit, sometimes forums aren't the best source of information, but I'm not complaining. I meant it when I said this should go into speculation. Obviously, lots of work has been put into a model that rationalizes hyper-ftl expansion of matter in a relatively small area, infinite density, and making unprovable conclusions with no evidence whatsoever, with just math, and no reason. I would suggest that the establishment would have been able to adjust the model accordingly to more reasonable specifications, but that perhaps they are infatuated with their own larger-than-life mythology, for who knows what reason. I remember someone named Martin who had a big issue with inflation himself. Why doesn't the establishment change? It's all just conservative, rational speculation, but why depict it as larger than life and drive people away in disbelief when you can be more realistic and still get the numbers to add up? I just don't buy it either, but I'm sure there is a good reason, maybe, possibly.

That does bring up a good point somebody made. Since the future goes forward indefinitely, why should it only go back 14 billion years? Unanswerable questions ... Considering the enormity of it, it doesn't make much sense that all of the matter would be congregated in one huge point, but if that's what everything points to then that's that. Expanding space can be explained just from matter disassociating. Space doesn't have to grow like bread dough, but the analogy works to an extent. If the space of the universe somehow grew ahead of the matter spreading ahead of it, I can see how this would give it more vacuum to pull with, to an extent, but has this actually been established, that space itself is growing or matter is just disassociating?

How does it diverge from BB theory? It incorporates it. Oh yeah, well yeah, I definitely should have put it in Speculations, since BB theory doesn't extend back that far. All day, every day, I read the latest theory, along with plenty of fact.
-
Recently, mooey depicted the BB as not being an explosion, per se, which draws to mind combustion or nuclear fission or fusion. With the creation of quark gluon plasma in colliders, one is drawn to a belief that the BB was more of a release from pressure, though I suppose an explosive process is still possible. Since it is postulated that the intense vacuum from the vast, empty space enabled matter to spread at ftl speeds (which is still fairly hard to believe since we're talking about the speed of light) this would mean that space already existed. Do you think it's possible that all of this matter existed in the form of one supermassive "superstar" in a massive, empty universe prior to the BB? This would still allow for the runaway expansion of matter once matter became sufficiently dispersed and gravity loosened its reins. I guess that wouldn't really be a star, per se, but a completely different animal, a "unicore".

Caffein did have a beneficial effect on a substantial percentage of people with Parkinsons disease, recently made famous by Michael J. Fox's young experience with the disease. However, I also found that it heightened the effect of people with panic disorder, which makes sense. In addition, it has a tendency to cause palpatations, indigestion, tremors, headaches, and insomnia, and just a cup a day caused women to be 50% less likely to become pregnant.

You want to fill up on something real dense, like a four pound steak. Make it five, to cover the difference lost in cooking, etc. You probably won't be able to eat it all in one sitting, but it will stay in you for a while.
-
It would seem that Inflation was devised in order to plug a somewhat unresolved difference into the equation in order to make ends meet. However, without being able to see that far for verification, not to mention the mythical nature of it, it always seems like that is the first place to look for errors.

Then why is pushing gravity on the Moon not the same as pushing gravity on the Earth?
-
If pushing gravity exerts pressure to keep us pressed against the planet from space, why isn't it affecting us differently indoors? Traditional gravity is a "force", but pushing gravity is just air pressure, which doesn't really add up to that much.

How do you know something is a reliable resource?
Realitycheck replied to Leader Bee's topic in Science Education
While physorg and sciencedaily are edited by highly esteemed, credible professionals, it is just a higher echelon news service. I believe caution needs to be exercised on theoretical positions. Anybody can always drill down with Google. -
So the average density of the sun is supposed to be about 1,400 kilograms per cubic meter, 160,000 kg per cubic meter at the core. I've been thinking about just what a such dense plasma would be like upon close inspection. Aside from the intense heat involved, would it resemble a malleable solid if it were contained in something like a bag? I guess there would be too much matter involved to simply squeeze it around. Does the density involved cause it to change its state into a liquid or solid?

Graphene is a form of carbon that is a sheet of atoms one layer thick which is being used in current research for applications involving microchips that are that small. So technology is already doing it. I've seen an application or two involving nanomachines.

It definitely needs to be specified if they are spatial or not.
