Well that's truly fucking terrifying

This makes no sense at all.

Why would only these two specific pipes get hot, so hot to glow, but not the other lines connected to it? And not the fittings around it? It's all copper, so even if the power itself doesn't heat them up, why would being connected to an extremely hot pipe heat it up. Since it's you know copper and being good at transferring heat is what it's known for.

And why would the lower resistance part be the part that get hottest? Low resistance means less loss, so those parts would in fact be the coldest of all.

Plus thin walled copper pipes can't get so hot they glow without melting or at the very least lose all structural integrity and break.

And a downed power line with a short to ground would almost immediately turn off. It's when there isn't a direct line to ground those things are dangerous. As soon as it shorts, it gets turned off at the source to prevent further damage, fire and not cause issues upstream.

Either it's Photoshop or someone has wrapped led lighting around some pipes.

Would killing the main breaker at least prevent the heating of the pipes so that the expert isn't walking into a potentially dangerous situation?

We found out a while ago that plumbing pipes aren't the best way to ground a house for a variety of reasons, and this is why ufers (grounding to foundation steel) and ground rods are now the NEC standard. Also, this is why bonding wires are important as well. If the plumbing were bonded to a proper dwelling ground system, the current would find a direct path to ground and trip the responsible breaker, instead of using the gas lines as a big ass resistor and creating the light show we see here.

I've never seen pex running into a house from the street/ground. It's always been copper up to the water meter at the very least and it's code (in NJ at least) to put grounding wire there.

Hey, there's particles, they are accelerating. You got what you paid for.

Normal person reading that: particle accelerator from TEMU

Me: oh god, there are TEMU particles??

Looks like it can run doom

Leave immediately and call 911 for an impending gas explosion. Tell them exactly what you saw, it will need to be disconnected somewhere very far away from the house. Aside from this being an obvious fake if you see a glowing pipe it’s the result of a deadly serious electrical fault that has bypassed at least 2 safety mechanisms that would otherwise prevent this catastrophic failure and at that point you really don’t even want to be touching the walls of the structure involved.

Run. That's what I would do. Then probably call the fire department, the gas company, or an exorcist. Possibly all 3.

Get the fuck out and call the fire department.

Go to the breaker box and pull the big one labeled "main". Then call the fire department.

Either turn off the gas if you can safely do it, or call your gas company so they can shut off the supply to your house.

“Build a man a fire, and he'll be warm for a day. Set a man on fire, and he'll be warm for the rest of his life.”

I'm sure the water put it out.

unless the gas pipe melted through

That looks pretty damn likely imminent to me...
