I don't understand why you asked... Why not just post reasonable question's and dialogue; I don't care who you were... 😉

@studiot do you know that you can "call" somebody by entering (at) @ character, and start typing person nickname, and the all suggestions will appear in drop-down list, where you can pick up the right one easily from the list? In your case, I just needed to enter "studi", to filter everything and limit list so "studiot" appeared. I his case, it just needs "saiy" @Saiyan300Warrior It has yet another advantage over entering plain name that referenced person will be notified about mentioning him or her in some thread.

Just be aware that sometimes Li-ion batteries fail by recharging very quickly. Unfortunately that 'full charge' discharges just as quickly as the battery is only taking a false 'surface' charge. This usually happens with cell phone batteries. ( 3.6 volt Li-ion rechargeable cells, Sensei )

Sure, they can measure different coordinate times. Those times can be a component of the invariant spacetime interval, without being invariant themselves. Different observers have different components that combine to the same interval. It's the proper time that is the invariant length of a spacetime interval. Everyone agrees on the time that a clock measures on its world line between two events. But to different observers, the clock's path with have different coordinate times, and different coordinate lengths. Consider an infinitesimal line element of such a world line. For some observers, the clock can be stationary over that line element, with spacial components of 0 and an infinitesimal time component. For other observers the clock is moving, and the line element contains infinitesimal spacial component. They disagree on the components, but agree on its invariant length that results each set of those components.

I really don't care...
