It happens instantaneously, at whatever distance. Ie it appears to enable information to travel from one place to another with no duration in between, apparently quicker than the speed of light.

yeah entanglement has been measured around 10,000 times quicker than the speed of light but i think its important to note that you still can't use it to actually transmit any information faster than the speed of light

still silly... technically he's right until the point where he jumps to the conclusion that "consciousness is infinite"

it might be true if you could reduce the idea of consciousness to just the electrons that are transmitting the electrical impulses of your brain, but imo it's really more a phenomenon that emerges from the structure of complex enough brains. without that, the electrons cease to have anything to do with consciousness

In biology structure is related to function. Even though the electrons in you brain never "die" they still can't form, on their own, the necessary structures that carry out complex functions (such as brain activity).

Ah, his name must've been Harold Armstrong. My mistake. Here you can see the tapestry of him getting ready to wank out of the spaceship with the help of his assistant Michael Collins who had to stay inside the rocket to film it for You've Been Framed and try and claim back some of the expenses

Yea true, I suppose it would be more accurate to say the essence of consciousness is infinite, without a way to maintain some form of organization of the energy in question as it is in your brain it wouldn't remain as "you" when it leaves your body.

What's the essence of consciousness and why is it infinite?

Also, how has there not been any discussion on Gravitational Waves famalam?

Physics has passed the singularity, there is more being discovered/developed than can be observed.

Yeah, that doesn't impede us from engaging in discussion of current affairs lol
I think what they found last month is a good indicator for them, well, perhaps it's more correct to say that I think it's a matter of time until they are.

from what i know about the field, as far as we currently know, the only mechanism to create the observed findings from the cmb polarization is through gravitational waves

the only other one im personally aware of is roger penrose trying to explain it through twistor geometry and a form of quantum gravity derived from it but ive never actually seen any technical writing about it, and it seems like its pretty much just him trying to promote his struggling 50 year old theory

anyways anywhere in the next 5-15 years i imagine we'll have sensitive enough detectors to directly observe them

I just didn't think that there was much worth discussing from the point of view of gravity waves. In fact, while the observation of the polarisation was effectively a fingerprint left behind by gravity waves (and therefore probably proof that gravity waves do exist), the more important point of the whole thing was that it was the first real evidence that inflation did in fact occur.

yeah i really think it's almost a higgs level discovery in terms of significance, the results will have a big impact on the constraints of inflationary and cosmological models and will help advance the field. it's probably even better than the higgs, since the higgs finding didnt really leave us with much information other than what we had mostly already predicted

Daily Mail reporting world poverty could disappear if we stop giving Saturn moon benefits... scrounging fat fuck of a planet.

On the topic of saturn I've been watching documentaries about planets recently and one was about looking for other earth-like planets that could have life on and they were saying that it'd require a saturn like planet to stop the onslaught of meteors.. another was claiming that saturns gravity actually flings meteors at us that were on course to completely miss us.

So does it do both? Protect us from loads but also fling some that weren't going towards us at us.. I assume it protects us more if both cases are true?

It's not impossible for both things to occur.
Not sure why they'd report it so haphazardly tough tbh.

This may not make a great deal of sense, but I'll try to explain myself :lol:

How do we know that gravity isn't a macroscopic manifestation of typically quantum phenomena?
I've got a simple idea of the sum of charges, for instance, of celestial bodies affecting the pulling or, better yet, curvature we see between them. I kind of don't want to get into the mathematical details, well I don't really know where to start with it, but is it possible, so to speak? Does this idea translate to lesser phenomena?
I'm currently reconsidering this post. I forgot about objects closer to earth, like paper falling to the ground.
Then again, that could be some kind of charge density thing.

Some thoughts.

Where has this been discussed? Anyone know of any research and/or theoretical work on it?
