'photons detected' The linked paper explains this in detail.

To answer this directly - sure. If you don't have to worry about fuel. You could even walk out of a gravity well at a snails' pace, if you had a really long ladder. Escape velocity is for when you have to give your rocket one good push at some point in your launch - typically at the start - and...

What would even be a standard for credible detection here? 3 events? 10? When would they start calling Stockholm?

I remain nonplussed about these devices. The automation of the observation process is so extensive that I don't quite get the difference between this, and going outside with a planetarium app on your smartphone, to look at pictures uploaded from the HST. Other than the missing 1k in your...

More or less. In this context it's specifically an idealised 'Fermi gas', so non-interacting. You can read more about this on Wikipedia, along with maybe an article on 'degenerate matter'. But I'd much rather recommend you study that book I indicated earlier, as it should - as far as I remember...

Can you please always cite the source you're referring to? As you say, there are no atoms as such in the core, just ionised nuclei and electron gas. The source might be talking about the degenerate electron gas becoming relativistic as the electrons are forced into higher energy levels, which...

As was suggested above, these requirements are somewhat contradictory. But I'll suggest something nonetheless. Go to Open Library, and search for Dina Prialnik's 'An introduction to the theory of stellar structure and evolution'. You can borrow it for free from there. It's an undergraduate...

How can an opinion be wrong?

Japanese is not particularly difficult, though. And in any case, hardly a claim to fame.

I like to imagine that in the bleak future of runaway climate catastrophe the desperate Greta Thunberg, in her later years, will have turned to dark science, combining occult and relativity to travel back in time in order to change the flow of history. She will arrive in early 2020s, appearing...

Are the fruit slices significantly below ambient temperature?

What can I say. That 'somewhat' may be doing a bit of heavy lifting there, but certain... dark desires have started to stir in me already. Most notably, the desire to sit by my window and tell those whippersnappers to get off my lawn. It's only downhill from there.

I am myself getting somewhat longer in the tooth, yet I've never written a cheque in my life, nor know anyone who has. I barely even used cash in the past decade or so. I grew up with analogue clocks everywhere, but would not be affected in any way if they all suddenly disappeared of the walls...
