Are the laws of physics always appearing the same? When I was a kid, instructors told us matter could never reach the speed of light, because an energy source would use up all the mass in our universe to accelerate anything with mass to that speed. He said photons do this by having no mass when travelling as light, and gaining something that gave them mass when coalesced as solid energy, aka matter.
It just occurred to me that nothing really acts in isolation, so what off something exiting a black hole is travelling against the local current of space contracting? Would it not appear to be travelling as fast, or maybe even faster than light, to someone observing from far away enough to not perceive the local shrinkage of space? No rules need be broken in the vicinity of the black hole, yet to a distant observer, the speed of light by this ejected matter might be reached or even exceeded.

I think Mr. Einstein built all his semi-classical stuff like Special Relativity (constant velocity) and General Relativity (acceleration and gravity) on the Principle of Equivalence. The laws of Physics are the same for all observers.
Doesn't mean you all get the same answers on measured things like velocity, and length. Or even whether things are simultaneous. I always understood it as saying the distance (s) between singular events in spacetime is the same for all observers.
s^2 = x^2 + y^2 + z^2 - (c^2 x t^2)
His other famous equation is:
E^2 = (p^2 x c^2) + (m^2 x c^4)
p is momentum. E is energy.
Which is the relativistic and more general form of E = m x c^2.
The Atom bomb equation. m is rest mass. c is the speed of light.
Neither is a quantum mechanical equation, so really a large scale (semi-classical) generalization.
The photon throws a spanner in the works because it has zero rest mass. But has Energy and linear and angular (or Spin) momentum. Both equations are wrong when Quantum Mechanics get involved IMO. 😕

It's the second track on that album where you can hear me say something, provided there's a good enough s/n ratio and sufficient dynamics.
How long is a rope? How big is a hole? How deep is that same hole?
At least until the next tide.
A very important instrument indeed, it utilizes those long-ish bits in the belly called intestine as an antenna. Sometimes indigestion or flatulence may call a slight disturbance in "the force". 😀my BS meter is a finely honed instrument.
The I'll try to refrain responding physics stuff beyond classical mechanics to you rather than being suspected of spouting BS nonsense. 😉
We are all doing the best we can under the current (terrible) circumstances. 😱
I have enjoyed the lockdown to a certain scholastic extent. But my mental and physical health has been tested. 😱
Highlight of my day is Jo Whiley on Radio 2. BBC Radio 2 - Schedules
She works hard to keep us cheerful.

First time heard that, I thought "What the Heck is THIS?". Turns out it is sampled 300-y-o Malawian music.

Back on Physics. Clearly something has gone wrong lately. Time to throw old ideas out of the window. Because it's not working. I think the Metric has to go. Just my opinion. 😀

There is an element of truth there.
The significance of the Higgs field to theoretical physicists is that it keeps the laws and equations of physics simple and symmetric, albeit while operating within a complex environment - the Higgs field.
So, in a way, the discovery of the Higgs field strengthens the existing laws of physics, keeping them elegant and uncomplicated, at least to a boffin! 😉
I feel an analogy coming on! 😀
Fish would consider the laws governing their motion to be complicated if they did not appreciate that they are swimming in an ocean which resists their movement.
However, once they accept they are swimming in a complex environment - the ocean - they would realise that the laws governing their motion are actually very simple.
For 'fish' read 'physicists' and for 'ocean' read 'Higgs field'!

But because such intensive experimentation/repetitive process goes into it's confirmation it could easily be an invention, an anomaly in the instrumentation itself.
When you find the anomaly in the following review of the measurements made during the discovery of the Higgs boson, please let me know.
I can't make head nor tail of it all! 😱

Not many people know this, but my Internet Avatar is not me. It is Robert Heron.
We have a vague resemblance. My eyes are rubbish, so I wear glasses too.
Robert Heron grew up in kinder times. He used to hang round with Patrick Norton. Who subsequently hung round with Victoria Belmont.
Victoria was more fun than a box of frogs:

Galu, I am relying on you to get an image of this. We need more female Physicists.

I've just found a gif' on Imgur of 'Veronica Belmont and her t-shirt' that will allow you to watch the salient moment ad infinitum!
I don't dare copy it here, so I've attached a still image. 🙂
I'm not sure that she's a physicist though! about.me presents: Veronica Belmont - YouTube

When you have to do 40 million repetitions per day 24/7 just to get the anomaly you're looking for( because that's actually what is necessary with current instrumentation) the competence of the equipment can't help but come into question. Also, are there neutral overseers? Who's checking the crew? The honor system? How are they/results taken to task? Can they be? How much money(and who's) was spent building the LHC??
If one thinks about it, how could the LHC have possibly found time to do 40 million repetitions per day 24/7 when it was busy causing earthquakes by sending plasma from Switzerland to Italy at high speeds, opening portals into hell or other dimensions, and shifting the world into an alternate timeline! 😱
For the Higgs, two separate teams were formed at CERN. They were not allowed to communicate or share data. They ran the experiments and each had to achieve 5 sigma agreement with the experimental hypothesis before announcing they had a result (or not as the case may have been). When both teams agreed, they could say ‘I think we have it!’ in true scientific understatement.
Yes, “five sigma” (5σ) significance is traditionally required by particle physicists to claim a discovery of a new particle or some other new effect.
This was the threshold passed by the Higgs boson on 4 July 2012. It corresponds to about a one-in-2 million chance that your result is just 'noise'.

About 5 sigma....
Interesting reminder.
So the Higgs boson gives mass to itself. A pretty weird concept.
What is the particle that gives charge to electrons ?
Who knows the electricity bill for this discovery ? Running the accelerator, the detectors, the computers.

Ugly though it is, I think we have to accept the Higgs Boson.
My friends, I think I have just proved Einstein and De Broglie's Uncertainty Principle!
Not only is the future uncertain, we can't even rely on the past. 😕
How could I forget that Victoria's real name was Veronica?
Perhaps not a physicist, but certainly a Tech person.

At 4.30m, a little kid threw the number 6084 at the maths guy to solve. Allegedly a cube of 26. Made no sense, of course. What had he done? Further investigation revealed he had multiplied 26 x 26 x 9. 😱
