This thread is so fun!
I love how we, humans, with our tiny minds try to explain and understand what really is beyond us. At least, we try.... |

QM does not include gravity, so it doesn't explain "all the great mysteries." String theory was developed largely to merge gravity with the other forces all into one framework. To do so requires adding a bunch of extra dimensions. Some argue that these extra dimensions are "rolled up" so tightly that we don't notice them. Imagine a person walking on a tightrope. To her, the rope seems one dimensional; she can go only forward and backward. But, to an ant walking on that tightrope it is two dimensional. Like the person, the ant can go forward and backward, but it can also go around the rope at any point along its length. This is an example of a tightly rolled dimension. It's only noticeable on a scale much smaller than we can perceive. If you don't believe in a multiverse, then I guess maybe you ascribe to the Copenhagen Convention, which many of the earlier theoreticians came up with about 100 years ago (Schroedinger was one of them). Their opinion was that a QM experiment can be in multiple states UNTIL a human being measures it, like the cat. That then collapses Schroedinger's wave function to yield just one result. I personally find that to be a bit strange and think the idea of a "Quantum Multiverse" to be a little less bizarre. That's the one (I've read about nine different kinds of multiverses) that says whenever a quantum event or experiment happens, ALL the possible results happen, but each different result creates a different universe. Copies of the experimenter end up in each one to read a different result. Experiments have shown that QM accurately predicts the results of virtually every experiment happening in the incredible tiny quantum domain to a very high resolution. It is very well tested. QM predicted the Higg's Boson decades before they built the LHC to look for and find it. Such a thing gives physicists lot of warm fuzzies. That's why it is considered a full-fledged theory instead of a hypotheses, which is an untested speculation or a what if. So, if you can't believe in action at a distance, then you are refusing to believe a well-tested theory. Back in the day, it was inconceivable that one could talk to another person who was on the other side of the world in real time. That's because they knew nothing about electricity or radio. Arthur C. Clarke's Third Law states that "Any sufficiently advanced technology is indistinguishable from magic." It does seem rather magical, doesn't it? |

What makes you so certain it is beyond us?

Remember the day when the Reagan (I think) was pushing the 55 mph speed limit? They had a saying: "55 MPH--it's not just a good idea--it's the law." I saw bumper sticker then that said "186,000 miles per second. It's not just a good idea, it's the law!" :-) |

Gravity is not a major part of QM, but is often included in the discussion. After all, many believe (as I do) that you cannot discuss some of the laws that govern the universe to the total exclusion of others. And as far as the Copenhagen Convention is concerned, it ascribes to much of what I said in my original post that I do not believe in. It's not just the multiverse, but also nonlocality and determinism that I have a problem with. You should read the book I referenced earlier (see below) which details how many well-respected scientists do not accept as fact what many other scientists do with respect to QM. We have harnessed a lot of knowledge of QM to advance our technology. But we are far from having a proven understanding of all things quantum. So as far as "refusing to believe a well-tested theory"...that is very true to a degree. I will accept it as fact when it proven, not just well tested. That has not yet happened and is not likely any time soon. The book describes this in great detail...

Someone said that "the fact" that we do not know what gravity is was just my opinion. So therefore he must know what gravity is or knows someone that does. Fantastic. Tell me.
The issue of will our brains ever be able to understand the universe can be illustrated by the impossibility of explaining how something "ALWAYS WAS". I can kinda understand how the universe can last forever but I sure can't fathom "ALWAYS WAS". |

Gene Rodenberry was amazing. Not totally sure which planet he came from really who cares, I enjoyed The Twilight Zone. Hi Gene where ever you are . My guess traveling . |

Gravity is a warping of space/time caused by the presence of mass. Basic General Relativity.

So you believe in Time Travel, I mean warping of space/time...……….just slingshot by a Blackhole, right. |

It’s all just theory. Some with more scientific backing and data. But still just theory. So if you want to just discard theories out-of-hand with no discussion, we’re left with nothing to talk about. So, to just toss a subject out there... Is light made up of particles? Waves? Both? Neither? Theories welcome. |
