According to Mullings, the reason for the association between mathematics and physics is not that the mathematics is causative but rather that mathematics studies the logical structure of possibility and constraint. As a result, if the mathematics successfully captures the possibilities and constraints in the real world, it will provide a tool for further analysis of potential possibilities.
Hossenfelder: What does this all mean? Well, it means that we might be close to finding a final theory, one that describes nature at its most fundamental level and there is nothing more beyond that. That is possible, but. Remember that the arguments for the existence of a minimal length rest on extrapolating 16 orders magnitude below the distances what we have tested so far. That’s a lot. That extrapolation might just be wrong.
As Chad Orzel explains, he considers Sabine Hossenfelder’s dismissal of much current physics “a little too sweeping.” A lot happened in the dull years.
QM is all about microstates and their measurement, but not about macroscopic properties that you and I normally associate with everyday objects–smoothness, ripeness, tools like “hammer and nail” or biology like “chicken and egg”. So indeed we can entangle QM microstates, but can’t entangle chickens and eggs, and therefore using those terms creates a semantic muddle.
He argues that a recent study shows that not only can two physically separated particles influence each other, they can influence each other through time and that it identifies a Mind behind the universe.
At Space.com: But ultra high-energy neutrinos shouldn’t be able to pass through the Earth. That suggests that some other kind of particle — one that’s never been seen before…
They are not principally data-driven. “In today’s fierce job market, fledgling scientists sometimes attempt to impress their senior colleagues with lengthy derivations marked by challenging mathematical complexity.” If he thinks evidence is important, that should rule out the multiverse.
Nope. Not a chance the proposed evidence will matter. The parallel universe folk probably don’t like our universe because it shows massive evidence of fine-tuning and that implies an intelligent origin. Any alternative theory will always be popular, irrespective of evidence.
Last April Astronomers finally detected some helium hydride in a gas cloud about 2900 light years from Earth.
The image is thought to establish that black holes really do exist; they are not just astrophysicists’ imaginings.
Because quantum mechanics “lacks a physical description of the measurement process. The open-access paper seems easy to read.
New Scientist suggests that split parallel universes would avoid the problem of messing with the past so that you don’t exist.
How about?: The Standard Model is terrible—until you compare it to string theory and the multiverse
In the post-science world, people can presumably define success according to their own frames of reference, in relation to their own facts and their own truths.
Of course, neither Wolchover nor Hossenfelder would be allowed to notice that design in nature is obvious but not inevitable.
