How Much Does a Shadow Weigh?

Perpetual Motion Machine

Jinx says...

>> ^Kalle:

One serious question that bothers me is.. why isnt it possible to use gravity as an energy source?
Would such a machine be a perpetual motion machine?

There is a bottom to a gravity well (apart from Black Holes? I don't know ). Say you drop an object and harvest some of its kinetic energy as it falls...what do you do once it reaches the bottom of the well? You must exert energy to pull it back out of the well, and that energy is greater than what you gained from dropping it. In a sense a pendulum makes this transaction with every swing. It does it very efficiently, only losing a fraction of its energy with each exchange but none the less it does lose energy. In a sense we never truly generate energy, we simply move it around. We break chemical bonds and withdraw a portion of the energy that was needed to make those bonds. Whenever we put an object with any mass on a high shelf we use some our energy and give it potential energy. Should it fall from the shelf this potential is converted to kinetic. The most plentiful supply of locked away energy? Probably mass. The speed of light squared is a big number, as GeesussFreek says, the future is probably fusion. If we can convert just a tiny fraction of this planets mass to energy cheaply and safely then our energy problems are more or less solved.

Anyway, I hope that somewhat answered your question. Its one of those questions that on the face of it seems simply to answer but once I tried I realised it wasn't so easy

To me this object looks like an extremely efficient pendulum. I actually love its design. The fact the ball "orbits" is actually very apt. I don't think its perpetual motion, but if it really had been going at near constant speed for that long then it is still a very impressive piece of engineering. He should patent and start making more. I'd bet people would pay a pretty sum for a scaled down version sitting on their desk. I would. Even better, put a lightbulb in the centre, surround it with 8 concentric rings for each planet and tweak the weights/magnets so the balls orbit at approximately the right speed...that would be fucking sweet.

..Coot looks like he wanted to get some extra mileage outta those modifications....

He's got the oscilloscope modified for hypothetical negative energy conversion..

That display in the center is so positioned to interface with the the invariance of the speed of light created by compensation for inference, and I'm only guessing here, that those buttons on the steering wheel/alignment cradle are some sort of Michelson-Morley interferometer.

Got a great deal onnit but he won't be able to keep a wormhole stable in an open perimeter....good try though, looks like someone helped their kid win a pre-school science fair!!

I'm Atheist for the record, I was ONCE Mormon, nearly 28 years ago! That is what shiny feels so compelled to mention.

Yes, I MAY mention it in what I write, but he ALWAYS writes this back to me and it is this that makes me SO angry, "I'm sorry, you were a Mormon, the Mormon religion is a cult, I'm sorry you belonged to a cult; you can't understand a Christian God because you belonged to a Cult, *I'll tell him an unrelated comment*, well that may have had to do with your Mormon upbringing, etc...

And it goes on and on in that type of vein and I'm sure others have had their fair share of these types of attacks to discredit them. Because, it really is to hard to go after the core facts or logic, they are so conclusive it's scary to some. So shiny has finally made me *ignore him, I will no longer hear what he has to say to me or this community as i think it's being abused. Even after what he said to me, he continued to ask ridiculous questions some of which I ALREADY ANSWERED IN MY LONG-POST! If you don't understand general and special relativity don't keep talking like you do! Read up on it and come back! There is a very good reason why changing the speed of light won't change the value of the age of the Universe... Go find out in the first place what makes the Universe the age it is, it has NOTHING to do with the speed of light, only the state of the energy of the photons we see returning to us.

If you changed the speed of light to something else like 10 ft/s/s then things of course would look awfully weird, but how a human measures "one second" is an imaginary concept, but beyond that due to relativity energy would be conserved, we would move FAR slower and we would still be literally interacting with each other at the same "framerate" we do right now. you could say that there is something special about our view of time as it is, but everything we've tested for shows time to be a imaginary concept. It all revolves around the speed of light, literally. It may be the only thing that determines how fast we are "using" time, if we were close to the speed of light stars would begin to live their lives FAR faster than normal, BUT you will always see one second as that.

So changing the speed of light is rather pointless, again I've made this case, to hopefully explain some of general and special relativity's little quandaries. Once again, light always travels the same speed in the same frame of reference (including its mediums). THIS has to do with CONSERVATION of energy, it is due to the law of thermodynamics, and you can take it farther than even this as well! People responding are coming off as ones that do not know much of what they are saying, maybe I've screwed up a sentence or two, I may admit (I didn't proofread and won't, I'm doing this fast). I hope that this is sufficient.

#shinyblurry I'm sorry I blew up, but you should NEVER use people's old life as a way to attempt to disarm them of their ability to argue. Atheism is to me "SOMETHING", AS MUCH as is the end of a pencil eraser: I've erased my belief in God and it is gone; I may be Atheist in wording BUT I'm not an atheist in any form or manner with BELIEFS, CONVICTION, POWER, HOLDINGS, JUDGMENT, or THOUGHT! IT'S a damned word! Nothing more.

Two as for being Mormon, sure I might agree with you in many respects about what it is and WHAT it isn't, but I might also agree yours IS nothing but the same. DO NOT think that this is because I'm an "Atheist" holding this against you. This is a MAN holding it against YOU! Religion has it's own shames to answer for in every color and theater.

And now I'm done.

light is special, it goes the same speed EVERYWHERE, EVERY-TIME, ALL THE TIME

Care to elaborate your point on this? The speed of light varies quite wildly depending on the medium it's going through, e.g. in diamonds the speed of light is c/2.42. Otherwise optics (along with other things) wouldn't work.
Granted that the speed doesn't vary within the same medium.


There is no actual evidence the speed of light is the same everywhere, or that it has never changed. That is a sacred cow in science. It is the same insofar as we have measured it locally and observed it in the near-past, although there are experiments showing it to be slower or faster. The uniformity in nature is an apriori assumption made by scientists, and one that couldn't be explained empirically even if it was true. Why should the future be like the past? Because of the past? That's circular reasoning.

You and me mean the same thing, don't jump on a bandwagon of the uninformed here (I know you're not I'm just being melodramatic). I am referring to the or within the same frame of reference, as you are. That means going through different "densities" like a fog or an ocean or even a crystal and glass.

It goes beyond evolution though, if I'm getting this right. FOR HELL'S SAKE we can use the speed of light to see things FAR, FAR, FAR, FAR, FAR^100 older than 10,000 years!!! It's a fucking joke. If you believe this you are an idiot. Period! = .
It's not just light and carbon dating, we have LOTS of ways to show this place is WAY older...

You're forgetting the Law of God Physics which clearly states God can do anything including making the universe appear much older than it actually is for the purposes of fooling his human creations so he has a way of testing their loyalty when he's not asking them to kill their first born son and saying, JUST KIDDING, at the last minute.


The funny part about this stuff is that they typically say that God "moved the photons" (atleast the semi smarter ones will) and the STILL dumb ones will say that, well light was, you see going a different speed back then so it still all adds up...YOU SEE!!!

BUT THEN!...If you understand relativity correctly like me you understand that you can change the speed of light all the time you want. In fact make it go 1 ft/second! It doesn't MAKE A DAMNED difference in how we will STILL measure the time gone/go/will go by! People never get this at all and it really is the sort of thing were someone mumbles under their breath when they finally understand what I'm saying/going to say: "Is that not amazing!!!". You see mass and energy are the same thing and light is special, it goes the same speed EVERYWHERE, EVERY-TIME, ALL THE TIME--and this thing called "light" are these little tiny particles/waves called photons that as I said before, but not quite as directly, they literally ARE mass and energy, so the relationship between us and light is so fundamental it SHOULD blow your mind. But, so many people went through school and listen to their preachers and have no idea how vitally important that "little" discovery that Einstein made was!!! So, even we at 1 ft/s light speed STILL notice everything moving and everyone we know moving at that same "time" measurement of one second (funny isn't it; but, light is traveling at one second as well, how can this make any sense..!?!?! Well here it comes, it is called relativity and the fact that light is a constant and the other very important fact that our measurement of one second really measures...what?) as we are literally stuck in a cage (this "cage" is called The Universe) that cannot be tampered with. This is all due to that little fact that our perception of time IS relative and our view of one second can be EXTREMELY messed with, but to us it will always seem to be one second--even if 1 Billion years went by. The age of the Universe comes from the SHIFT of energy in the photons present that we can see coming from other places in any direction around us; so God would need to put THAT hologram there nothing else, BUT there is a giant problem in doing this (because due to our friends that want God to actively fuck us over for some reason--the hologram only extends technically 10,000 years out and "hides" the rest--if God put everything the way we see it and it isn't even an illusion--what can I say at that point if God was real I would join the Devil in less than a heart beat to overthrow his LYING, SADIST, and moreover EVIL ass!) If the hologram WAS there then: the hologram, it would need to be different in EVERY single direction you look; every time you move one Planck length (I might be wrong, maybe just the length of a photon) further out into space God would need to fix the energy distribution to make his illusion look correct... YOU HAVE no idea how absurd to the absurd degree this sounds, even GOD would spend his entire existence doing this because the job would require this long to do it: forever (until the UNIVERSE STOPS!). I'm not kidding it would be utterly ridiculous (from Earth his "image" would look right, on Mt. Everest, it would look wrong,; in space it would look wrong--in fact if you have sensitive enough equipment every square foot you took would somehow end up looking incorrect--we're talking about the cosmic background radiation, the little thing that lets us know how old our Universe is and that everything around us is moving away from us...

So that comes to the "putting the photons into place syndrome". For the most part I'm starting to think that these people like to abuse their brain in secret rooms with paint, huffing it until they collapse in a heap. in the morning they slowly scrub the white vinyl paint off their nose and mouth and go start with the blue. The problem with this is God had to of atleast put photons 13.5 Billion years out for this to even work--so in the end it falls so flat on it's face it makes no sense. If he was using a hologram, where is the border? Why do we detect gravitational anomalies when those have been proven to be real locally? It just goes on, and on, and on, and on.

I'd love to hear them explain why space may be full of Dark Matter or better yet why is "nothing" full of something called "The Quantum Foam"--you may have heard of "Vacuum Energy", same thing more or less--look it up it's fascinating and may even be the source OF "The Big Bang". Why can we pull photons (from "nothing") out of the Quantum Foam? According to lots of religious folks you can't create something from nothing, but WHAM, there it is! Sometimes, it just might be a bad idea to hold onto your old per-conceived precepts if they do not allow for change. BTW, the photon coming out of thin air was in a very well-known (now) experiment and is HIGHLY worth looking up; you can find details about it in my Videosift Blog (which is entirely about it).

You could disprove their crap all day. The truth is is that they did bad in their science classes, they just didn't get it and for some archaic left over juvenile resentment, they must have their righteous rite of "The Comeback Minister (or Preacher/Prophet/Father/etc...). So in revenge they are taking the easy way out and saying, "Hah, see I didn't need to learn that stuff from Mr. Scrampton in 12th grade! I'm a Minister now and I can just TELL you what is right, because I know it's right in my gut; especially after five cases of Budweiser!". Now they never tell you the truth. They lie, they tell you it "came" to them, like their a prophet now or something. ...Well if they can be prophets, why can't we? Oh wait, scientists do in fact fill this role and they do a good job at it. they constantly warn us of dangers and things the government should do. But, there are far too many damage control freaks with their own agenda running around and they seem to cling to religion as it satisfies very easily their questions, making it so they don't have to work to find the actual hard ones that exist and that we DO need.

It's not in the Bible that any of these idiots would tell us anything meaningful, nor the Koran, or any other holy book. So I find it strange that so many line up and then sit down and listen to these idiots blather on about the world and how to cure it and what it's ills are. They also as I said do a great deal of "re-education" in THEIR vision satisfying that old juvenile, washed up nothing who couldn't get over the fact that he wasn't good at science off the bat or maybe even when he tried too. This is the bane on America (and I would assume many other places, but America has a lot of this). They are teaching and re-teaching our people ridiculous notions and since they require very little work to understand, just community, people believe it--especially because it's being believed in numbers and that is the important part.

Now this was a longer post than what I wanted it to be and it also went past the scope of my original intentions. BUT, the reason why those statistics exist is due to the nature, the epidemic of how people are being re-taught forcibly (you think like us or you are no longer with us--it can have shocking community affects, especially when it becomes a inter-family problem...I know this EXTREMELY well due to my Mormon upbringing; when I became an atheist I was shunned and cut-off from the community, at first. they slowly let me back in when they realized I was an extremely good person, usually a better person than many of the people in the Church and so my neighbors finally no longer cared--cared what the churches stance was either--who or what I was, they took me for what I was--IT TOOK 20 years to happen!). So many people are started and taught young this is a HUGE problem, I know it's a major one with the Mormon church. You are baptized into the church at eight. You should hear the things they ask you to accept and agree to--they are things that only and adult with experience could properly answer (more like someone that is 25) yet an eight year old surrounded by their family and peers of course can give only ONE answer.

After that, you being to be taught all the incorrect things you could possibly think of. If you are even semi-devout like me (and this goes for many other religions as well) going to public school in Utah, the church has LITERALLY built seminary schools next to every High School and Junior High (and this is true outside of Utah too, as I'm SURE Idaho, Arizona, Colorado, Wyoming, and Nevada--maybe more too, I'm sure they have them locally to attend--I'm sure many of these states have these institutions built right next door or somewhere for kids to attend) you will attend seminary due to the wishes of your parents (my parental situation was beginning to change--and for the better).

Still I attended seminary through grades 7-12 and could have continued in College, but I was agnostic by then...if not basically atheist, just not strong enough to say it. Seminary had it's wonderful parts, but the mis-information was a joke. luckily I was smart, very smart. So I was able to separate the information apart from each other and it allowed me to ask STRONG questions about my one time faith. These questions and their mis-information EASILY killed that religion for eternity, for me--for A LOT of reasons. Many of which, many of you know...easily. It came to ME slow. SO when i talk about helping other people you need to realize what we are up against. facts that do come to us easily usually don't to them and it typically has to do with their past. but, it is HARD to get them to talk about their past openly. For one thing there is no possibility of them being wrong or in danger of it. Somehow we MUST change this.

Ron Garret -- What Popularizers of QM Don't Want You to Know

jonny says...

"QM is no more difficult to understand than relativity"

I've always found some of the "weirdness" of quantum theory to be a little easier to wrap my peabrain around than some of the weirdness of relativity.

Honestly - consider the Doppler effect. With sound waves (and every other wave except for light/EM, so far as I know), the frequency of the wave changes depending on the relative velocity of the observer to the wave. But with light, we can observe the Doppler effect while the relative velocity is constant (speed of light remains constant regardless of the observer's frame of reference). WTF?

Best of Actual Detention Slips -- farting and jesus

wormwood says...

When I was in 5th grate, the teacher was telling us that the speed of light was the same as the speed of sound. Even the 10-year-old me knew this was false so I raised my had to say so, pointing out the obvious delay one sees when watching another person dribble a basketball some distance away. He still didn't believe me, but he was up for a wager and allowed me to run off to the library for an encyclopedia. I returned with the facts and won the bet, all of which he took very gracefully, unlike the teacher in the video here. In fact, what I won was less detention because the bet was for plus or minus one "demerit", which was his way of tracking small classroom infractions (e.g. missing homework, coming late, acting up) that could add up to a punishment assignment if you got three of them in a week.

Massive Solar Eruption

MonkeySpank says...

When you consider the radius of the sun and time it took to leave its surface, the matter jetting out of the sun is probably at or near the speed of light. Fascinating!
