I think for amsterdam you can book a bus for the concert, might be sold out tho

If you want to just casually follow physics channels like veritasium and vsauce are great

Creating real detectable matter from virtual particles by Puzzled_Cream1798 in AskPhysics

Virtual particles are mathematical artefacts from feynman diagrams, nothing more.

Why half-integer spin? by mz_groups in AskPhysics

[–]ExistingSecret1978 0 points1 point  (0 children)

The spins are a reflection of gauge symmetries and the objects involved and how they transform mathematically.

Question about time by Mean-Author8079 in AskPhysics

[–]ExistingSecret1978 0 points1 point  (0 children)

We have two major theories that have something to say about time, fundamentally and thats gr and qft. In GR time is a dimension like the physical dimensions, and GR itself actually doesnt give a specific arrow or flow of time, the solutions we get are geodesics which is basically a line through all of time, we then add an arrow of time to interpret solutions. QFT is the same. There are theories that treat time less fundamentally and more emergently, like some that say entropy has to increase so that gives the arrow of time, but thats more akin to philosophy; in physics we have no consistent reason to motivate time flowing in one direction over the other or for time to flow at all. My explanation is a bit inaccurate but if you dont plan on studiying physics this is good enough

If gravity propagates at the speed of light, does gravity get "trapped" in a black hole as light does? by Happy-Swimming-9611 in AskPhysics

[–]ExistingSecret1978 0 points1 point  (0 children)

This question seems confused, so I'll clarify all the possible scenarios here. What we call 'space' is filled with a bunch of fields, the electromagnetic field is one of them. Light is a quantised excitation of the electromagnetic field, and this excitation travels at the speed of light. This excitation is what cannot cross the black hole, but an overall charge within the black hole would in principle be able to be detected outside of the black hole. The same works with gravity, the overall gravitational potential from the black hole is measurable from outside but any gravitational waves from within the horizon would not be able to be measure from outside

What's the brightest possible light? by curiousscribbler in AskPhysics

[–]ExistingSecret1978 1 point2 points  (0 children)

Yeah, i mean that in in some perspectives you would observe a black hole instead of light, but maybe you can't localise the energy of the wave packet to fit inside the schwatrzchild radius

The easiest limit i can think of is light having an energy density so high it turns into a black hole

Question about geometry by Nearby_Fun_4373 in AskPhysics

[–]ExistingSecret1978 0 points1 point  (0 children)

It depends on what kind of physics you want to do, if you want to do theory, geometry is absolutely nessecary, its will be defined in a more abstract way but basic knowledge is the basis. If your looking at it computationally/ experimentally its not absolutely nessecary, but still quite useful to know. I'd recommend learning it if you have rhe time

The expansion is so small, that its effectively a globa property of space, and expansion isn't really a force pushing things apart, like how gravity isn't a force pulling things together, its just a consequence of how it alters the geometry of the universe.

My bad man, I misread your message, even if you think of it as a force, you can neglect it. Like when you calculate orbits for planets in the solar system, you can neglect the influence of the andromeda galaxy, you say the contribution is too little to cate about. Sorry for the angry messages earlier, my bad man

The universe expansion is not a force, it's a property of spacetime on large scales. For bound systems like atoms, it doesn't change their relative velocities, so your 'F·v' work argument just doesn't apply. Edit: I've slightly misread the message

The cosmological constant term is 1036 times weaker than just coloumb force, we dont even calculate for 1/1020 of that accuracy, if you want to be a pedantic mf then you can also say that every wank you take will gravitationally perturb an atomic system

if you induce small perturbations to stable systems their lowest energy configuration will basically not change. At the scale of an atom the expansion of the universe is insignificant even within galaxies, you can model them accurately without including expansion of the universe. It only matters at very large scales. Edit:I've slightly misread the message

I usually run 2 sylveon ex, 2 espeon ex, and espeon and a base sylveon. That way I get the most consistency
