Is Eric correct that string theory has held back progress in physics for two generations or is Brian right that it is a success no matter what?
@Donate_Please 3 місяці тому
I don't know who's correct. But String theory has done nothing for me except teach me a bunch of interesting nonsense that turned out to not be true. It did spark my interest in science for a time, so it's not all bad. But if instead of string theory, had there been a bunch of Einstein's working on GR the world would probably be much better off.

I think String Theory is like the idea that 2+2=5. Yes, it can be proven with math but in no universe does two apples added to two apples equate to five apples.

I have read all of Brian Greenes books and give him credit for my deep interest in physics. He is such a wonderful presenter. But I gotta say, my feeling is String Theory is a very contrived answer to what’s going on. But what do I know I’m an armchair theorist.😊

The basic problem is that String "Theory" is not a theory at all. It is a purely and ridiculously complex mathematical hypothesis which has absolutely nothing to do with physical reality. They should've learned something when SUSY was debunked at the LHC. And worse, it was never even a fundamental theory by its own admission. I'm sure Greene's a nice guy, but he's done a lot of damage.

As I've said elsewhere, ST simply "followed the math." People threw shade on Einstein, on Dirac saying their math was just mental onanism that couldn't really be describing anything real -- but the math did eventually prove correct in real-world observations. Sure, it can be a rough road. Who can forget Pauli's comment to Dirac: "Just because the energy goes to infinity, that doesn't mean it's zero." Bottom line: If the math works -- and problems like energies being infinity and/or zero are eventually ironed out -- ST works.
@rishavkumar8341 3 місяці тому
Dirac, Einstein and Pauli produced hypotheses that were verified. These string "theorists" have utterly failed to reconcile QM with GR on theoretical level and they haven't produced any predictions that can be verified by experiment. It is an absurd dogma and it is high time that its priests are called out.

Well, we will always defend whatever theory we invested most of our personal time in. No one wants to admit they wasted their post graduation life. Brian wasted his time on string theory, Eric on GU. Both men failed in this respect as obviously neither theory is a road to simplicity, merely complex mathematical approximations at best. Newton was the first and last great physicist as he was desperate to find the ToE in the most simple principles possible. All who came after him claimed to do the same, but in reality they looked for the truth in insanely complex mathematics. In their mastery of mathematical complexity they felt superior to all others. They couldnt be further away from the simple fundament of physics. Human vanity trumps human intelligence…still.

Math mapping a certain minds way of rationalizing the universe around us has value and benefit but not acknowledging this is the only issue I have. I dont have any issues with mass displacement of space creating the by product of gravity or that every plank length gradiant has a vertical axis of time. This falls apart on smaller & larger scales so its a bad foundation to use. It seems to be a contrast between those who really want deterministic linear direction magical woven into the fabric of reality and those who are perfectly fine following the evidence where it leads. Trying to bend reality into manifolds or changing evidence to fit some human bias seems extreme to me. We tried and funded this with the most money ever ,the most brain power ever ,using the best tech to aid it and yet nature continues to tell us the same results. Its been many different lines of evidence telling us nature don't work like humans can manipulate systems. How many different generations finding similar results does it take?

I've been really pondering something for a while now and I have been wanting to ask and hopefully it's as interesting to others as it is to me... I understand it's all relative but I want a better answer. Is there a way to come as close to absolute zero speed as possible? So like I get that if we shoot a rocket close to the speed of light and we come back everybody's going to be older but can we shoot a rocket the opposite speed of the Galaxy and come back and everybody's younger and we are the old ones? I guess we could never get to absolute zero because we would have to shoot at the opposite speed of the universe and we can't do that from within the system? But my question is still bothering me. Can't I be shot the exact opposite way at the exact speed and be considered going slower? Or is rest on earth the slowest that we can get? Or Is it only achieved through being cold?
@maxwellblackwell5045 3 місяці тому
No. That's not how time works. It's not about the direction you are headed. The faster you move, relative to another object, the slower time will be for you. If you came to a speed of zero compared to another object then your time would move faster than the time for that object or person so they would age less than you.
