They're human like everyone else, and try to use language that is specific and descriptive. In this case the word direct observation has become to mean something very specific In the field of astrophysics. It's not out of malice or anything, just results from the difficulty of scientific writing, so you use words that already have established meaning.

Direct observation ≠ direct detection

I would argue that dark matter is much more based on indirect observation, things like rotation curves and baryonic acoustic oscillations.

Confusingly, direct observation does not mean the same thing as direct detection.

This study "directly observes" a hypothetical dark matter signal. However this is distinct from direct detection experiments, where a dark matter particle is found in a collider.

I am a physicist, studying dark matter.

Firstly, It would be nearly impossible to prove that dark matter definitely does not exist.

And secondly, there are no alternatives to dark matter that come even close to explain our universe as successfully as dark matter.

That doesn't mean it's right, but any explanation without dark matter is not favored IMO.

Alternatively, if you can't remove the modem, find and remove the antenna. And if you can't remove the antenna try and surround it with a metal, like aluminum foil.

Well I'm probably wrong then, framework said they couldn't get good performance and maintain signal integrity with upgradable memory for the Ryzen Max cpus, so this is likely discrete Cpu and GPU. Probably all soldered in the same mainboard though.

This seems to blur the lines between desktop and mobile APU's, but I would bet that's it's closer to a higher clocked mobile chip, than it is to desktop. The only reason I think this is the case is due to the similarity spec wise with the Max 385, and that it's semi-custom.

If it was just a 7600x CPU + 7600 GPU I think they would have just said so. It could be separate CPU+GPU, but I think it might be possible that it is built more like a SOC, where the GPU is just given its own dedicated VRAM.

Looking at the hardware of say a PS5, it has 16 GB of GDRR6, the same as the Steam Machine's VRAM.

If everything is soldered anyway, there is no reason to have separate chips for CPU+GPU, especially if that hardware already exists like the AMD Ryzen AI Max line.

This thing has pretty interesting hardware:

The chip almost looks like a cut down AMD Ryzen AI Max 385, but with fewer CPU cores and GPU CUs, but the GPU gets its own dedicated VRAM, rather than sharing it, like it does in something like a Framework Desktop.

It also seems like it gets a decent amount of power, so likely at higher clock speeds, performance should be pretty good for not that much money. If this is supposed to be a console then it can't be much more than a PS5 at $550 or PS5 Pro at $750.

The universe was only 3 billion years old at the time, and that time period is very anti-life for the universe.

I think i would love this phone, but unfortunately for me does not support many US phone bands
