1. ## Are photons massless?

There are multiple ways you can look at it. First you can consider that the term 'universe' refers to a closed system by definition. It is defined by modern physics as "all of space and time and its contents" - nothing can enter or leave it, because an "outside" of the universe does not exist. You can also consider that time symmetry holds for the universe under Noether's theorem - the source of our conservation laws. For every (differentiable) symmetry there is a conservation law and the symmetry with respect to time results in the conservation of energy. As such, the
2. ## Are photons massless?

In simpler terms one would say that mass is weight divided by gravitational acceleration (9.81m/s2). This is because, in physics, 'weight' is defined as the force exerted on an object by a gravitational body such as the Earth. So to find the mass of an object, we find its weight (in Newtons, the unit of force) and divide it by 9.81. This is what your set of scales does - or rather is what it is calibrated around - as the result of this calculation is the mass of your object in Kilograms. So a person of mass 100kg would have a weight of 981 Newtons. Day-to-day English uses mass and
3. ## Windows alternatives?

I'd say this depends on who you define as the "Linux community" Certainly I wouldn't go browsing the likes of /r/Linux or pretty much any Linux subreddit - they are in my experience quite elitist and not noob-friendly - I'd recommend avoiding them at all costs as an experienced Linux user, let alone as a beginner... But places like the Raspberry Pi forums or even /r/Linux4noobs aren't bad at all. At the very least you don't have to deal with the constant Anti-Windows circlejerk that often emerges in other Linux forums, I believe due to most of the people there not using
4. ## Windows alternatives?

Others have suggested Ubuntu which - while I personally loathe it - is not a bad choice as a beginner. My choice is different however: Raspberry Pi OS. Buy yourself a cheap Raspberry Pi 4 (the 4GB one is the best all-around choice) and load Pi OS onto it and play. This way you don't risk not having a PC available if something goes wrong with your desktop - you can keep your Windows install for work purposes. Don't try and dual-boot - there are just so many ways that it can go wrong (and is - as a result - a common source of the errors seen in beginner-friendly places like /r/linux4
5. ## New GoPro Hero 10 Black Announcement

I think different parts of it are available to different products. The camera exchange is available for the GoPro Fusion and the Hero 5 or later, while the video upload is - I believe - for any GoPro except the Fusion due to its huge file size, as it seems to be handled through a companion mobile app. I believe you need a Hero 7 or later to livestream at all so that is probably a requirement for the livestreaming thing here as well.
6. ## New GoPro Hero 10 Black Announcement

With a GoPro subscription you can get a "no-questions-asked camera replacement" if you damage your camera (twice per year) which is pretty sweet, as well as unlimited cloud backup for photo and video taken on your GoPro. Also allows you to livestream at 1080p to anyone using a private URL generated from your account and gives you discounts when purchasing products from GoPro.com. Honestly, sounds like a great deal if you ask me. It's not a "you can't use your camera if you don't pay this" kind of subscription like the Hero 10 purchase options suggest and frankly \$50 a year for unli
7. ## Developer suing Apple for (again) for stolen keyboard on new Apple Watch

2018 release date was for the iPhone app. The Apple Watch companion app (which is what this lawsuit is about) was released in 2020.
8. ## SATA Drives Dis-Connecting. Intel Rapid Storage?

Dead chipsets definitely happen - they're not as common as they used to be but aren't unheard of. Usually they won't even post and so are very hard to diagnose vs other motherboard issues (probably won't even get a post-code), but they can also partially die in the same way that a CPU can.
9. ## SATA Drives Dis-Connecting. Intel Rapid Storage?

Definitely sounds like a flaky SATA controller... Would still try a reinstall of Windows to your M.2 to see if that solves the issue - could just be a driver issue. The fact that the drives with stuff on them are being affected but not the empty ones suggests that it may be occuring when the drives (and therefore the SATA controller) are under load - could try some large transfers to various drives to try and test this hypothesis. Have you been moving large amounts of data to/from the HDD recently?
10. ## How big of a deal is PWM on case fans?

Highly depends on the fan with non-PWM fans. They work though voltage-control but depending on the fan (and your motherboard) the amount of control you'll get can vary wildly.
11. ## SATA Drives Dis-Connecting. Intel Rapid Storage?

You said some of your SATA drives - this suggests others have not? Take a hard drive that hasn't been experiencing this issue and install WIndows. If you boot to the desktop, does the issue remain? If no: check what happens if you move your old boot drive to use the same SATA port you just booted from. If the problem returns, congratulations! you probably have a software issue. Give up on your old install of WIndows and migrate everything you care about to a new one. If it does not return then you most likely have a issue with your motherboard. You can either continue to use it fro
12. ## Z690 with mixed ram support

ATX, Mini-ATX, Mini-ITX. Some of these will be basically the same board but with the addition of WiFi, and then there's the D4 identifier at the end of the SKU name indicating DDR4 support. Some boards like the Prime Z690-V are listed twice, once for each RAM generation. Combine these and you only really need a handful of base configurations of VRM etc. Create one for each combination and the numbers rack up fast. Then there are the specialty models - the watercooled edition, the ProArt edition with a 10G LAN card etc.
13. ## Nintendo Switch is finally getting Bluetooth audio!!!!

Nope. Bluetooth audio wasn't supported until now, it was used for the controllers.
14. ## Nintendo Switch is finally getting Bluetooth audio!!!!

The implementation kinda sucks though. Latency is terrible with my Sony WH1000 XM2s, seen many reports of similar problems with other similar headsets. No AAC, no LDAC, no aptX (only uses Bluetooth 4.1) so any third-party adaptor is still a better option. According to Techradar the only options are A2DP and SBC... Ouch... Using BT audio also nerfs the number of controllers you can use at a time to two (a pair of joycons counts as two controllers) and prevents you from using any local connectivity. Also no microphone support at all but that's not a huge deal.
15. ## Are photons massless?

This is incorrect due to the fact that the Planck mass is not the lowest possible mass an object can have. It is merely the energy scale at which the quantum effects of gravity are strongest. For reference, the Planck mass is 1.22 x1019 GeV. The mass of an electron is 0.51 MeV, or 0.51 x10-3 GeV. The energy you have given your photon is actually incredibly high for a single particle, far more than is achievable in any particle accelerator on Earth, which only reach the range of 10^3 GeV (TeV scale). A photon with this level of energy (known as a gamma ray) would most de
