Vexen has been suspended for a combination of soapboxing and spamming. Far too many threads opened up with no further participation (and when participation is there, it is often of the category "tell me more"), and includes threads that are topics easily Googled. This is a discussion forum.

Why is there something rather than nothing?
! Moderator Note You need to do better than a link to an audiobook.

I can imagine a perpetual motion machine, entropy spontaneously decreasing in an isolated system, and instantaneous transport over an arbitrarily long distance.

The Lagrangian equation...
It's a month later. I don't recall which reference.

What is your favorite tv series at the moment?
The situation is complicated, so the action builds slowly. If felt the same about The Sopranos. Watched the first episode, thought it was boring, wasn't hooked, never went back. But The Wire hooked me, way back when, even though it had a bit of a slow build.

What is your favorite tv series at the moment?
I don’t know if it’s 4K. I watched it on my iPad.

The Expanse (though it is now an Amazon show and not technically a TV show)

The Operator has been banned for violations of our rule against slurs, and even more posts that hinted at such tendencies. We are just not interested in entertaining those conversations.

The Lagrangian equation...
If you're trying to check and see if you're correct, you should check this against your references. You cited a wikipedia reference that has discussion and also a list of references. I would check there.

The Lagrangian equation...
This just appears to be the Lagrangians of different interactions. As such, it would likely not be "derived" in any more detail. In classical (nonrelativistic) mechanics, the Lagrangian is simply L = KE - PE https://en.wikipedia.org/wiki/Lagrangian_mechanics It's a way of solving problems using energy rather than forces. Which lends itself to QM problems, since you don't really talk about forces and kinematics at the quantum level.

Are glass batteries a hoax?
! Moderator Note I have snipped the last post owing to copyright violation concerns. You can't just copy a web site and post it here. The details are at the linked site

"L'appel du vide" moments
Yes. While I can believe it’s fairly common, suggesting that it’s nearly universal is a stretch.

Snoopy has shot down Theredbarron, who will not be returning to our skies until after the weekend. Repeated soapboxing and an inappropriate response to moderator action.

What is Space made of?
! Moderator Note Let's stick to the topic of the OP The discussion on "time is energy" has been split https://www.scienceforums.net/topic/117599-time-is-energy-split-from-what-is-space-made-of/

The Quick and Easy Experiments thread.
It’s everywhere. https://en.m.wikipedia.org/wiki/Electrolysis_of_water http://www1.lsbu.ac.uk/water/electrolysis.html Feel free to update the wikipedia page

The Quick and Easy Experiments thread.
Probably not. The reaction requires a minimum of 1.23 V, and you need more than that from your battery, because the potential drops throughout the circuit. AA gives a max of 1.5 V, and it’s lower for rechargeables and alkaline batteries thst have been used. Two in series, though, should work. >5V would be even better
