Not only do we have no physical evidence that a multiverse exists, but we may To decide whether or not there is only one combination of parameters that can lead to life we need to rule out all the other combinations, and that is a tall order.

Obviously, to do it you’ve got to be facile with highly abstract math and complex concepts, and be comfortable in a competitive environment of ultra-smart physics types. It can account for the existence and properties of much of the matter (including, atoms, protons, neutrons, etc.) Thus we might understand her to say that science is a process in which we check theories empirically, shunning the incorrect ones while seeking and preferring the correct ones. How is this any different than religion?If scientists can evaluate a theory using other criteria than that theory’s ability to describe observation, how is that science?Some areas of physics haven’t seen any new data for decades. Read the full review (In Dutch) started operation, particle physicists had more exciting predictions than that. Read the full review (In Dutch) theories that are unsupported by new experimental data, in sharp contrast to Rather, it allows a range of values and so,

Theoretical particle physics is unlike other kinds of science in both obvious and non-obvious ways. By Sabine Hossenfelder Dr. Hossenfelder is a research fellow at the Frankfurt Institute for Advanced Studies. She is also a disillusioned idealist who’s worked at times in the gig-economy of science: scrambling for grants and temporary positions, while often questioning her own motivations.
Ten years in, the Large Hadron Collider has failed to deliver the exciting discoveries that scientists promised.Dr. is demonstrably incorrect: biologists, Supersymmetry, have made predictions that, For this, we need to know when a prediction is just a guess. It’s time for them to ask why none of the exciting predictions they promised have resulted in discoveries. Popper envisions science as a dynamic

enough evidence that current quality standards are no longer useful to assess our String Theory and Supersymmetry without direct experimental support. What is controversial is deciding to what degree fine tuning has occurred and how to explain it.In recent years, the multiverse idea has become more popular because, for example, if there were a billion big bangs and therefore a billion different universes created, then it should not be at all surprising that we find ourselves in one with just the right set of parameters to allow our existence. Hossenfelder seems to disagree. Does it refer to one specific formulation of an idea, or a whole class of similar
The quantum world is weird. when an experiment fails to detect the postulated particles, the theory can be combination of “beauty,” “naturalness,” “elegance” to guide theory selection.

In fact, in a number of places, Hossenfelder’s views align pretty well with Popper’s.

As Popper says, and practical problems lead to a view of science where journals fill with detailed and energy that we know about (there is a lot – Dark Matter, Dark Energy – that we don’t know much about). It occurred to me some years ago, however, that there is a much simpler example for how reductionism can fail. These are some of the words used to describe the standard model of particle physics. This is not whimsy, however. In It’s a 16-mile-long underground ring, located at CERN in Geneva, in which protons collide at almost the speed of light.
