I can't tell if you aren't smart enough to understand Sabine and Weinstein, simply don't understand the information available, or have been watching idiots like Sean Carrol
I can, however, tell you that you don't understand what science is, or how it functions.
String Theory is what has been debunked
It has not. In fact, the criticism against string theory is *precisely that it is pretty much impossible to debunk* because you've got so may parameters to mess with that you can make just about anything work with string theory. It's a bit like overfitting: if you want to find an equation that perfectly fits your 10,000 data points, you can certainly give a polynomial of order 9,999. Is that going to accurately model the mechanism that caused the data points you gathered, or be a good predictor for additional sampling? Not necessarily. You've overfitted the crap out of your model, it behaves weirdly between the points, it treats random noise or outliers as deterministic and valid, etc.
Is this what's going on with string theory? Maybe. It could also be that it's right. It's *really hard* to come up with an experiment that could falsify it with the technology we currently have. Does that by itself mean it's wrong and we should give up on it? No. Does that mean we should also be looking at other avenues? Yes. And we are, there are plenty of physicists who work with alternative theories and are vocal critics of string theory.
and it is a well known fact that scientists have not been doing very much real science for decades
There is no person that holds that belief that isn't a moron. You included, thank you for outing yourself. I won't respond to any more of your responses, because I do know that debating idiots like you is like playing chess with a pigeon: You knock the pieces down, shit on the board, and strut around like you've won. I'll continue answering your post for anyone else who cares to read so they can understand WHY you're an idiot, but I don't really care about your opinion.
- 1. Anything that is rigorous is real science. It's not defined as useful to you right now. Anything we discover, whether the path we're going down ends up being correct or not, is valuable.
- 2. I'll let Angela Collier, who, btw, *also* does not like String Theory and happens to agree with you that it was a waste of time, tell you about many of the exciting discoveries made in physics over the past 70 years. I'm not even going to address the point you said "scientists" in general, as in, making the claim that ALL science has apparently been a standstill for decades, where the world I live in today is barely fucking recognizable compared to the world I lived in 20 years ago. I don't mean just in technology, I mean in terms of what we know. My god, we have NEVER been in a time that is more prolific than the time we live in right now, whatever you're learning in school will be outdated by the time you leave college, will be outdated by the time you get a graduate degree. If you're not learning while you work, you're a dinosaur and your job is at risk. The world of science today moves FAST.
String theory is just maths masturbation
Maths masturbation is *great* and we need more of it. This is one of the problems with Sabine: she likes to go, "it's just math." Buddy, If it's not rigorous math, it's not worth anything, if it is rigorous math, and it doesn't match reality, the paper it was written on is still worth its weight in gold. Do you like the world you live in with online baking and secure encryption? Thank all the mathematicians of old doing number theory for the sake of it, finding properties of prime numbers and elliptical curves. Einstein didn't like Minkowski's use of a four-dimensional spacetime to frame his special theory of relativity and then he learned it turned out to be super useful, and embraced geometry when developing his general theory of relativity, and embraced something else that essentially had no use outside of pure mathematics at that time: tensors.
If (and I do mean if, because like I said, it hasn't been 'debunked' as you claim) String Theory turns out to be COMPLETELY wrong, all the work done in it will be useful to advance what we discover is right.
You and Weinstein need to engage in a little bit more of "Maths Masturbation". Especially considering his "geometric unity" theory doesn't have enough math in it to be a rigors theory. He should get on that.
If you don't believe me ask Roger Penrose
Roger Penrose is a brilliant man whom I highly respect, who happens to disagree with String Theory and actually most of the direction that any quantum theory of gravity tends to go towards. Most physicists want to quantize gravity, he thinks they should instead be trying to explain quantum physics in relativistic terms. Now, he's in the minority with that claim, but he could be right, and I appreciate that someone is making strides toward that. Although he often uses strong language to disagree with, I *seriously* doubt he would say the people working with it have "wasted their time" or aren't doing "real science."
I also want to point out Sabine is pretty critical of CCC, Penrose's theory he hopes will replace the inflationary model. Because Sabine, isn't trying to propose alternatives. She pretty much goes, "I think string theory has go nowhere, oh well. Let's just not study it or any alternatives anymore, lest we do any math masturbation." That's not science. Creating hypothesis, making the theory rigorous, and testing predictions is the job.
