As for IDE, supposedly the best one is PyCharm (community is free). But most people nowadays probably use VS Code.

Sorry for a philosophical take on it, but I just wanted to remind, that you, as in human mind, are not just made of matter. There are also electrical fields propagating inside at the speed of light (but not in vacuum, if you look from a high level), interacting with matter. So when answering the...

Universe could potentially have a fractal-like structure, rather than become homogeneous at some scale.

Its kind of interesting if the scale of the universe is the only exception, and it happens, that this theory removes this exception.

I think they do claim that though, hence my question. Actually, I think, that the idea to compute considering only a single source makes some sense, as at least from what we see most of the matter is mostly affected by a single strong gravitational source with relatively rare exceptions for...

When I say freely falling, I mean lack (or negligible amount) of orbiting, or a non-gravitiation related force, that'd keep us afloat. Only in that sense. Sorry for confusion.

Re-reading it now too.

How else would you describe a cosmology with a gargantuan black-hole(s) in the center with our visible universe freely falling to it, and getting stretched?

That's a good question. And, thinking of it, it was incorrect. But I'd still see it as non-uniform. The picture, that comes to mind is an expanding thick sphere. Seems obvious, that for an observer in that sphere, stretching along directions on the surface of the sphere will be uniform, however...

I am looking at a couple of very interesting papers, published in MNRAS, that deduce, that the accelerated expansion of the Universe we observe can be attributed to gravitational waves, produced by a very distant merger of two or more universe-mass-scale black holes. The last one is on the...

You really got me worried about perspectives of deep space interstellar travel with this one. I guess that bothered my conscience, so this morning I got up with idea, that potentially we could recapture those photons at the starting point, if the whole trip is planned well.

What I meant is that you can in principle create an entangled pair of clocks, one made of matter, another of antimatter. The clocks do not necessarily have to share the same quantum state to behave identically (as clocks). P.S. I am not trying to answer OP's question. Just clarifying your...

Irrelevant to the topic's main question, but is cloning theorem really applicable here? Doesn't no-cloning theorem say, that you can't build a machine to clone arbitrary existing quantum system? That does not seem to prohibit in any way an ability to make some specific system twice. Also, for...

Correction: we do not know any other way to make it work currently. Fusion was though to be like that at some point. Also, we don't really have a good theory for small black holes.

Wait, what about the energy of gravitational collapse? If ever managed, it would be usable for actual energy generation, and not just storage (unlike antimatter), and also could produce just an order of magnitude less energy than matter-antimatter reaction (which will still be several orders of...
