It's not just mass that warps spacetime. It's any contribution to the stress-energy tensor, which means even the energy of massless photons contributes. If you somehow manage to pack enough photons together into a small enough volume, you can generate a black hole. That's called a Kugelblitz.

Yes, though that is separate from rest mass. It has (as far as we know) a rest mass of zero. Its energy is still equivalent to mass and contributes to the stress-energy tensor (and thus a photon does exert gravity, just incredibly weakly).

Photons have no rest mass. But they do carry energy, which contributes to the stress-energy tensor, so they do exert a (very tiny) gravitational effect. They also travel through spacetime and are thus of course affected by gravitational distortion of spacetime.

Try Half Life Alyx, then it'll technically be VR sickness rather than motion sickness.

As long as they can add PCIe 5.0 later, when it's needed, this all sounds good to me.

There hasn't been any significant change in how AIOs work or are manufactured in the last 5 years. You were probably unlucky back then and more likely to get a better one if you buy now, but that's purely by chance.

It depends on the resolution and even more so on what games you run, but generally a GTX 1060 is a bit less than you'd want for a high refresh rate monitor.

I don't believe those limits are accurate. In any case, a motherboard can be configured differently or have a secondary controller that effectively (sort of) adds more lanes.

Just depends how the manufacturer allocated the chipset resources, and whether they used any secondary controller chips to provide more connectivity.

They're using a more expensive motherboard and CPU, though you're right that the CPUs are pretty comparable in performance. You also haven't included a CPU cooler and Windows key. So maybe the prebuilt tax is more like $500 Canadian in this case. Still shows you why prebuilts are not normally recommended. There may still be better prebuilt deals around, but this certainly isn't the worst you could pick.

At 3600 MHz those are really good timings.

Not that realistic as it's dried. I'm thinking of a proper goopy thermal paste between the pins. That's gonna be really annoying to get out, just flooding the place with solvent isn't a good solution to that either.

I don't see any reason you couldn't have a better latching system with PGA, just AMD has picked a pretty flimsy one for some reason. Also, I completely disagree that it's easy to clean an LGA socket if you get thermal paste into it.

Yeah most likely. Lots of small files could slow it down but your HDD should be able to transfer faster than 20 Mbps (2.5 MB/s) on average.

Just depends whether it can be reinstalled in the new location. Steam and some other stores can do that.
