thats my point though. In science, evidence is gathered by predicting what results you would expect if your theory were true.
String theory has absolutely no way to collect any such evidence because it makes no testable predictions. At best it could be called a "proto-science", but it suffers from what is called "unfalsifiability", meaning, there would be no way to prove the idea wrong.
as of now, there is as much reason to believe in string theory as there is to believe in unicorns, save the fact that it is really smart and qualified people who talk about string theory

true, that doesn't make the idea any more scientific
EDIT: that being said, I've never heard someone phrase the string theory problem in terms of tech. The problem is the strings exist in different dimensions that we have no ability to access. might tech solve this? sure, but this isn't JUST a tech problem

You've actually made a fair point; however, it might be said that the inability to look beyond the membrane of our own Universe is a technological one. The thing is M theory has some evidence to support it, but the evidence that supports it also supports the big bang... There might be ways our technology will be able to prove or disprove string in relation to the formation of the Universe via tech etc. It's probably the best bet at observation. We also need a way of observing the affects of micro dimensions on the 4 we are aware of again a tech issue.

no, totally
I'm not trying to say string theory isn't right or that we can't someday figure it out...
I guess it really is just envy of physics. Stuff that is like what some guy would write on a napkin gets books and media coverage... who even knows what an fMRI is?

I do, but then my degree 20 years ago was in Biotech.

In a certain sense there is less reason. We know what we're looking for when it comes to unicorns. If we see hoofprints in a place where unicorns are supposed to be hiding we know to follow it. String theory currently has an infinite number of solutions which have been narrowed down to "just" 10^500 solutions that match the basic rules we see in the universe but are all wildly different in what they predict. To extend the metaphor: paw prints are also count as a sign of unicorns, so human prints, bear tracks, train tracks, even nothing at all.
String "Neat Idea" doesn't have quite the same ring to it.

I lol'd for real
I tend to put a little more faith in something that the physics community takes seriously, but I hear you 🙂
String "neat idea", ha!

Yes, they absolutely were. I'm not saying String Theory should be abandoned (I'm sure there was a reason for the original supposition its based on) just that its ridiculously overblown. The idea that "the world is round" was meaningful when it was proposed. Presently the idea that "String Theory is true" is not.

if gravity acts through the warping of spacetime, and not through the transfer of energy through a sub atomic particle, this would be the end of the graviton.afaik, they are mutually exclusive theories...
If relativity says gravity is warped spacetime, and quantum mechanics says gravity can be quantized, the implication is that spacetime itself can be quantized, and I think herein lies the difficulty integrating the two theories...at least, this is how I conceive it.

It does integrate nicely lots of other ideas. I do like frameworks.

Basically, yeah, I agree.

oooooooooooooooooooooooooh
ok, thanks 🙂
what evidence is there for this quantized "quantum gravity"?

Glad to see that other people can appreciate this, most people I talk to about these subjects tend to give me odd empty glares of "wtf is he on about" 😱

😆 Its quiet clever really when you think about it, I suppose the question is will it have an effect on our lives at all knowing this sort of thing.
Originally posted by inimalistAh. In that case, if I may, I think the proper question might be: What is the equation which explains gravity on the quantum scale? In other words: there is no 'conceptual' reason why gravity -- spacetime -- can't be quantized; just WTH is the equation for it??
I guess my question was more like, "why can't warped spacetime be responsible for 'quantum gravity'?"
Numbiz, man. It's all numbiz.
