#Zoomposium with Manfred #Rumpl: “In the footsteps of #Schrödinger - Or how much #philosophy does #physics contain?”
In this interview from our series “Physics and its limits”, we talk to the Austrian writer, educator and philosopher Manfred Rumpl about his book “Travelers in #Relativity”, which traces the life of the Austrian physicist and philosopher of science Erwin #Schrödinger.

Einstein’s Relativity Predicted a Twisted Illusion – Now Scientists Have Finally Seen It…
When things move really, really fast, close to the speed of light, our everyday ideas about #space and #time start to break down. This is the heart of Einstein’s special theory of #relativity. Objects actually shrink in length as they speed up, and time flows differently for them than it does for someone watching from the outside... #physics #science

* universe has filament structure (mass along filaments; empty "bubble" spaces)
* differential relativity (time) dense/empty spaces
1/2 So we know #Youtube channels that will post and title with excessive or blatantly false claims wrt to some open question in #Physics but then follow that up with an interview with a principle researcher explaining entirely valid work they are doing.
Let:s say someone is thinking #Gravity might have a scaling factor that breaks #Relativity over huge distances. They could take several approaches to this , flattening the tensor, fixing certain properties to show where the deviations are…
I got physics on the brain at the moment so here's a tidbit..
We all know time gets weird when you approach the speed of light.
The tidbit is time doesn't change for the person who is moving. Local time is always one second per second.
That doesn't mean when you get out of your spaceship it doesn't get weird it means your time doesn't change.
...so naturally there's more. Reading off bits via incommensurate scales breaks some important symmetries. Since our first pass notions on #Causality are time dependent we have our first suspect source of the
" flaky" bits on the time axis in the #Tiimespace of #Relativity. We don't need extremal conditions to require time corrections in practical applications as satellites in near Earth orbit need relativistic corrections for GPS to work at all. Relativity is odd but it works extremely well
2/3…there is very often a group of people talented enough to be grappling with core technical principles but more comfortable as “spokespersons” due to not having physics or other degrees.
Well, we can and should help these people. Many of them understand at a basic level for instance -the issue of the incommensurate status between #QuantumMechanics and #Relativity. We have these typically known equivalences between matter and energy…but then the notion of #Information that requires neither…
@fesshole
No you don't. All motion is relative.

…about the physics. What’s left are hard problems. We’ve picked off all the low hanging fruit. The #StandardModel still wins #Survivor in terms of fitting (most) observations, experimental or otherwise. #Protons have not suddenly started decaying. #QuantumMechanics still helps us find ways to beat alleged limits on circuit building in spite of #Relativity getting the kids on the weekend
TIL: Conservation of energy is a simplification. On a cosmological scale, energy is _not_ conserved.
Unifying general relativity and the electromagnetic force? (I presume this also includes the weak nuclear force at sufficiently high energies, but this summary doesn't say)

I'm pretty much at the limit of my understanding of field theories and such just in this summary article, I don't think I'll even try their full journal article.
@cenobyte - Does Professor Skye or her research assistant have any comment on the matter?

What Is Hidden In The Core Of A Neutron Star?
On this day, six years ago, on 12 April 2019, both @LIGO instruments and the Virgo detector observed the gravitational-wave signal GW190412.
It was a signal like none before, because GW190412 was the first to come from two merging black holes with very different masses. Never-before-heard overtones in the frequencies of the gravitational-wave were observed. These also allowed a more precise determination of the properties of the two black holes.

About a year later (on 20 April 2020), the paper with all the details of the discovery was published.
