Ignoring the fact that Belgium is one of the worst affected countries, I'm not even sure what you're arguing? Belgium is the prototype for what would happen elsewhere if you're just a bit less successful at getting a handle

I'm always surspised that we're still arguing about this. Look at the excess mortality in Belgium: https://ourworldindata.org/grapher/excess-mortality-raw-deat... Supposedly, that's with the percentage o

There's a difference between what observers see, and what happens. In the abstract, in a 2d spacetime diagram (ie ignoring angular degrees of freedom), the event horizon is just a line, and an infalling timelike worldline will cross it

Why do the two waves add up? Because the electric field only has a single value at any point in space. The equations that describe this are linear (ignoring quantum stuff irerelevant at these scales), so the waves combine by simple additi

We never discussed this in our SR lectures - instead, I stumbled upon it in a creationist paper where someone tried to finagle a young earth out of it. For example, you can use a convention where the speed of light is infinite for infalling

Being German, I don't consider these countries part of Northern Europe. While the UN might put the UK there (but not Belgium), the way I got taught the terminology, the UK would belong to Nordwesteuropa as a sub-region of Westeuropa

How many times have there been rewrites from C++ to Java that ended up being faster ? A couple of times as far as language implementations go (eg JRuby vs CRuby, even before the whole Graal/Truffle thing). However, that's a nich

That's where the analogy breaks down. If you take Einstein relativity at face value, there's no priviledged spatial slicing (contrasting with, say, Lorentz ether theory), and the balloon is not really a thing. The most obvious int

I agree that it's fair to describe cosmologists as a species of theoretical physicist, given the long standing connection between the observation of heavily bodies and the birth of the modern physical sciences. Still the relation is r

No, we haven't. See above. No we have. See above: While redshift goes all the way up to infinity, in terms of cosmological time, there's still only 0.4 billion years between z=11 and z=∞, or about 3% of the age of the universe.

Which is no different in other branches of physics: Have you ever seen a quark? If you have a model that makes testable predictions, it's science. Cosmology is not only science, but physics, making your original comment contrasting the

Note that the most distant astronomical object we've observed has a redshift of 11, corresponding to a light travel distance of 13.4Gly. This means that if our models are correct and the universe is indeed about 13.8 billion years old,

There's conformal gravity, which replaces the Einstein field equations with ones derived from a conformally invariant action. Like MOND, this allows you to fit rotation curves nicely without invoking dark matter, see eg [1][2]. [1] ht

It depends on the way you look at things: Noether's second theorem works fine in General Relativity (in fact, this was the historic context of her paper). So for any given time-like vector field, you'll get an energy conservation
