Field lines aren’t physically real, they are a convenient way of describing the value of the field, like elevation contour lines on a map. Interaction with field lines is just a way of looking at an equation the depends on E or B, or on a derivative, which is sometimes referred to as “cutting” a flux line. It’s conceptual only.

I think this is moot; this isn’t a lecture, it’s a discussion forum. I think it’s an unreasonable expectation. I don’t see where you’ve typed in all that many equations in these discussions. I wonder, if you had done so, if your typing skill would stand up to the same scrutiny and criticism you have offered up.

Much the same way you “fix” a pet

But if they have positive energy, when they annihilate you have energy where you had none before, which means energy is not conserved. It’s not what I require, it’s what the description of Hawking radiation requires. Not sure where this comes from We’re talking about the virtual pair, though, without other constraints. IIRC the magnitude of the gravitational PE is less than the mass energy in this situation, so one particle escaping has to result in a loss of energy from the BH. The coordinate system isn’t going to matter (it can’t; you can’t have something that happens in one frame be impossible in another) It’s not a weird, fake theory. This is a common description of Hawking radiation. https://www.sciencealert.com/hawking-radiation# http://www.physics.hmc.edu/student_projects/astro62/hawking_radiation/radiation.html

Do you have a model and/or evidence for this?

You learned that virtual particles have positive energy? What happens when the pair annihilates?

I took that as differentiating between the particle and the antiparticle. matter vs antimatter.

You don’t quote (including enough for proper context) or link to this claim. That’s what I mean by not bringing the receipts. The mention that I saw was here, in the context of Hawking radiation, and the particle that reduces the mass of the BH is indeed associated with a negative energy, because it’s a virtual particle/antiparticle pair. That’s why the mass decreases, and how you get real particles emitted as radiation.

At least two of the objections above are likely typos; = instead of + and n instead of N are issues of not hitting the “shift” key at the right time. If you can’t be charitable about typos, you might not have the right temperament for online discussion. I can’t fathom how one gets from that to “pseudoscience” And as I’ve suggested before, complaining without bringing the receipts? No. It’s just whining.

What’s the made-up part? What is your support for the claim? And what is your definition of pseudoscience? It must differ from mine.

As I said, we use the earth because that’s where we are. That makes it best purely from a practical standpoint, much like choosing a particular frame of reference makes it easier to solve a problem. You won’t get a different answer by using another frame, as Mordred notes above.

I agree that this isn’t going to affect anything. Points of fact can be discussed in their own threads. I don’t know what axe there is to grind here, but that’s what this feels like. “Is this word salad?” smacks of argument by personal incredulity. If it was, one should be able to point out why. If you don’t know, it means you don’t have sufficient knowledge to tell. Labeling it as pseudoscience is similar - you should be able to show that it is, and nothing close to that has happened

How does time running slower in the past mean that it is expanding? Doesn’t that imply a longer duration? i.e. slowing down?

Doesn't matter; the expansion is not from a single point. We use the earth because that's where we are.

Thread bumping is something we discourage. Other people probably feel similarly about some of their own threads, and if they all get bumped, nothing changes - a thread on page 4 is still on page 4.

it’s not offered as a definition; as I said, you assume certain knowledge on the part of the thread originator. The context of the statement was in response to a claim about reference frames - “A worldline cannot be associated with two different reference frames” The issue is whether the statement is correct or not. An answer to a post is not expected to be a tutorial on the topic. It certainly does not rise to the level of pseudoscience

And yet there are manufactured controversies.

No? Manufacturing controversy isn’t a failure of integrity?

If they are reporting things accurately, then they aren’t in the large swaths that aren’t. Large number, perhaps, but limited reach. Indeed. Almost like integrity has taken a back seat to profit. Maybe because Trump winning means more money for the bosses (tax cuts and all)

When someone posts a thread on a topic, it’s OK to assume they have the requisite background knowledge to discuss the topic. No need to reinvent the wheel. “ALice has one reference frame Bob has his own reference frame” is inconsistent? Inconsistent with what? Um, no. Events do have their own reference frame. That’s not claimed, nor are dimensions given I don’t see where “spacetime interval” is mentioned at all One post can’t establish a pattern, and you haven’t shown what you’re claiming. Sounds like you asked for clarification, but are complaining that it didn’t tie back some earlier point, but there’s no reason that that needs to happen.

Why would it?
