String theory is misnamed. It is not a theory. It is barely a hypothesis. Maybe a speculation ?

Until it can be tested empirically, meaning it must generate a testable prediction, it is just pink unicorns.

What do you mean by that............its just a speculation? Its in the freaking dictionary: "a three dimensional hypersurface embedded in a higher dimensional bulk." As a hypersurface....shirley we can run around and play on it?

Fair enough. It's just a mathematical model like the standard model of the atom. However it was the application of "field mathematics" that lead to quantum mechanics......so......you may as well start from somewhere.... :D

Yes - just strap on your HyperbootsTM and you can play to your heart's content.

The standard model of the atom led to testable predictions.
Quantum mechanics led to testable predictions.

Those predictions were tested and could not be falsified, giving strength to both ideas.
String "theory " has not done this.

to be fair, String Theory doesn't aim to be more accurate than Relativity and Quantum Mechanics; it tries to combine the two into a unified theory and remove the cases where the tow contradict each other.

So it's more a question of whether is ST is more elegant/efficient than switching between the two theories as necessary.
Currently, it isn't.
I've come up with a set of rules that describe our reactions to technologies:
Spoiler:
1. Anything that is in the world when you’re born is normal and ordinary and is just a natural part of the way the world works.
2. Anything that's invented between when you’re fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it.
3. Anything invented after you're thirty-five is against the natural order of things.

String Theory Finally Does Something Useful
"We can use string theory to solve problems in a different area of physics," said theoretical physicist Michael Duff of Imperial College London. "In that context it's actually useful: We can make statements which you could in principle check by experiment." Duff and his colleagues describe their findings in a paper in Physical Review Letters September 2.

As Electric Monk states, String theory is a model that includes gravity. In this article, String Theory predicted something else which wasn't expected.

That is fine, Matthew. But there is saying about the proof in the pudding ......

In other words, string theory must be used to make a testable prediction, which is then tested. If that is done, and the prediction is not falsified, I will be very happy to take it more seriously.

And by the looks of it without a poodle sorry paddle. If you widen your aperture you will not have to sit there like two peas in a pod waiting to get mushy over the next theory base. You can see the reality of it instead. The source of the universe cannot be governed by the universe's that it manifests. And there are lots of them.

Ultimately there can be no single set of rules that could possibly explain all physical interactions in the observable universe because the consciousness of it is changeful and always on the move (simple logic). Your dream world hangs on a thread of consciousness (this is your string theory) :lol:

You don't know what you are doing from one day to the next, even your quantum theories predict this uncertainty. Of course you have a technical idea but you see how ignorant your science is? You are trying to test things on the smallest of scale without having the technological ability to do so. In regards to truth, life, reality, consciousness you will always be chasing your tail and getting lost up your rear end. But hey when you are ignorant of your own ignorance what do you expect? :mrgreen: 's

Those of us who study science are very, very aware of how little we know. But, the real ignoramuses are those who try to avoid science and come up with intuitive ideas to replace science. Those guys are the genuine crackpots.

You really are an idiot. The rule of the universe were established .00001 nanoseconds after the big bang, when no conscious thing was present. You simply suffer medieval religious narcissism in thinking life has anything to do with the rules of the universe, when no life was even present for billions of years. :lol:

Emergence creates new laws out of selecting only parts of the basic physical ones.
The universe wasn't created for life, but life is making a great effort at bending the universe to its will.

On the contrary. Life, consciousness, reality is independent of the mind, it is neither conscious nor unconscious. So which Big Bang are we talking about here? There is one every time consciousness explodes into being. Life as you know it was not present billions of years ago. Life as it is has always been the case. Whether there is an observer or not is irrelevant.

Yes Lance, indeed they are. And there are those of us who acknowledge the genuine crackpots and their genius. If it wasn't for these people science would not be where it is today.

Like ellard you study books lance or rather other people's findings, thinking for yourself would probably be too much of an arduous task for you. The way I see it it is not avoidance but rather seeing the obvious.

No, Confidencia.

I think for myself. But unlike the crackpots, I apply a little discipline to my thinking. This means I do not come up with clear signs of ignorance and silliness. I do not postulate stuff for which there is no empirical evidence, such as the universe having a consciousness.

Who cares? You made a really stupid religious claim that the rules of the universe are defined by consciousness, yet there were no minds, consciousness or anything other than photons, electrons and protons when the universe started and its rules were defined.

Your religious fantasy makes no sense. Go away.
