didn’t it fail the criteria for clearing its neighborhood or something like that though?
either way who cares? its all semantics. make it a planet again, and throw eris in too
Some people are way too attached to Pluto’s planethood.
so for some interesting news. There might be a planet sized amount of water trapped in the earth’s mantle in the form of hydroxide. If so, that’s some interesting news. The hydroxide seeps through cracks upward into the crust via techtonic shifts.
This could imply that water didn’t come from space, but most of it came from within the planet. Pretty mind boggling.
John Oliver’s hilarious interview with Stephen Hawking
Big bang BICEP2 team admit they may have gotten it wrong
Cosmic inflation: Confidence lowered for Big Bang signal
This is what I love about science.
People are willing to swallow their egos and admit they’re wrong.
Even if it means years of work will go down the drain.
Same thing happened with the “faster than light neutrinos” in 2011.
Always love Hawkings appearances on comedy shows, good find :tup:
The Unbelievers with Richard Dawkins and Lawrence Krauss is available on Youtube, iTunes and Amazon.
It’s pretty good. Not as many cameos of stars as I thought it would have.
It was more about the debates and discussions that Krauss and Dawkins have had with theologians and each other, and behind the scenes stuff, etc.
Could have been longer, but still satisfying.
Dedicated to Christopher Hitchens.
Bored scientists are now sticking random things into the Hadron Collider to see what happens :lol:

I’m pretty sure I’m going to get some hate for these videos, but oh well.
Matter is only solid when observed by the Observer. When it is not observed, it collapses into wave form. Matter abides by the expectations of the Observer/You/Me/Everyone. Matter has a dualistic nature; it either there or not there. Reality is nothing and something in the same time. We are all part of The Hologram, if you are part of The Hologram, that must mean you are The Hologram itself, therefore you are all of Reality or God. Reality is God.
no that’s not true.
Matter is matter, and doesn’t chage structure because somebody is observing it.
Take a 222 inch block of say brushed aluminum. Now imagine being in a bright room, and then gradually dim the lights, until it’s very dim, but not dark.
If I take what you say as truth, then the block changes color and texture, not because the lights where dimmed, but rather, because I somehow subconciuosly changed the physical properties of the block. It just happens to coincide when I dim the lights only.
Which isn’t true. The block of aluminum is simply behaving according to it’s physical properties that are set. Since there’s less light to diffuse and reflect, it’s going to change apperance, but it’s not going to change physically. I just happen to be able to notice the diffrence in apperance, it does not mean I changed it though. I’m simply the observer locked to a particular perspective. Changing my perspective however will not have the effect you speak of though.
The block is still going to have the same atomic structure, and other physical properties unique to aluminum, with or without me.
You are taking Schrodinger’s Cat and trying to combine it with a bunch of other ideas to conclude what you said. That’s not to say that you the observer cannot have an impact the physical properties of a material. You can and there’s several sciences dedicated to this. But you the observer cannot collapse matter into a wave form by prescence alone. You just see and feel the diffrent waves of radiation emited by an object as it interacts with other objects that are visible and invisible.
The main issue is that the certainty of an object increases with the more mass it accrues. This makes any direct observation of quantum superposition on a macro scale indecipherable, because even the wavelength of visible light is larger than an atom.
Doppler effect, too if the mass was a result of near ‘c’ speeds. Relativistic velocity/time travel in reality = things around start glowing from irradiation after a certain threshold.

When quantum mechanics describes things in wave form, that just means we use a certain mathematical function to “contain” the properties of a particle; that certain function has to be a solution to the wave equation, that is, the function can be used to model a wave.
The most popular interpretation of the wave that your function represents is that it determines the probability that a particle’s properties fall within a certain range. It turns out we can’t really measure some properties to an arbitrarily great precision, properties like position, momentum, energy, and time. We can measure a range of values that we know our properties lie in, though. This is handled mathematically by adding multiple waves of different wavelengths and amplitudes, since one wave corresponds to one position, momentum, etc so you get a wavefunction (the total set of waves that you added together) that corresponds to a range of multiple values. The quantum interpretation of this addition of waves or “superposition” is that all the different properties of these different waves are true at the same time.
When the particle is “observed”, the wavefunction collapses to a single state. It may sound pretty mystical, but all it’s saying is that when the particle interacts with something (for example, bumps into another particle), the particle acts as though it only has ONE position, ONE momentum, etc instead of ALL of the positions within the precision range at the same time, etc. It’s essentially like common sense: you can know that a particle is somewhere between 5-6 meters in front of you, and since it’s probabilistic, you have to take into account every possibility (that the particle exists at 5 meters, 5.1 meters, 5.2 meters, and so on), but you’re sure that the particle is just in one place.
So no, matter doesn’t “abide by the expectation of the Observer”. It just takes on a single set of properties when it interacts with something. (Interaction with something is actually a pretty good informal definition for “observation” in quantum mechanics; there doesn’t have to be a sentient thing literally watching the particle)
Also, this doesn’t mean that matter is nothing and something at the same time. That’s contradictory. It is necessarily SOMETHING, ALL the time. A pretty important characteristic of the quantum wavefunction is actually that its total probability over all of space is exactly 100%. That’s because you know that the particle definitely exists somewhere, and definitely has a momentum, and definitely has an energy, etc.
Everything you said about The Hologram and after, I can’t really get. I’m not saying it’s not true, but I just wanted to make some corrections regarding the “wave form” and the “dualistic nature” that you brought up, which seem to refer to quantum mechanics.
Richard Feynman said "I think I can safely say that nobody understands quantum mechanics."
That was in 1965. I don’t think that’s true anymore. I think physicists have got a pretty good grasp on QM nowadays.
Has anyone else besides me seen this? I dunno if this has been brought up, but mecha within the next 5 years for sure(I will see to that myself, powered armor/mini-mecha in progress!)

The first part of this video is a good explanation of the physical interpretation of QM (didn’t watch to end, lol). There’s a good demonstration of how particles act as if they have multiple different sets of properties all at the same time, but when it is observed you just find that it has one set of properties (the wavefunction collapses).
It reminded me of this video from MinutePhysics, which is a bit relevant to the topic (sorry if this has been posted before lol, I’m kinda new to this thread, didn’t read much of the previous pages):
Basically, physicists want to know how to study particle interactions without observing them, so that the particles keep their wave form while interacting.
Also, I suggest watching the other MinutePhysics videos if you haven’t done so already. They’re mostly conceptual; they helped me understand some things in modern physics before actually rigorously learning the math behind them in my physics courses.
this is useless for mecha applications until we develop power plants that are energy efficient and produce more power than convential sourcces.
