Freedom of Speech.
It only applies to government-related situations. The government, is not allowed to silence you over criticisms and open opinions against it, try as it might.
It does not apply to online communities which is where a lot of people seem to believe so. As much as it sucks for it to happen, moderators can and will delete posts of yours that they find uncivil. You do not have immunity whatsoever, to express any opinions that break rules and interrupt civility. You don’t have the right to openly call someone “you’re a fucking moron” then turn around claiming that’s free speech. That’s not how it works.
The government doesn’t own or fund places like Lemmy, Reddit, Facebook .etc They may have done dealings with those platforms, but they don’t really own them and it still does not count towards the 1st Amendment. That’s why you get banned, that’s why you get warned and that’s why it may seem to you, that you’re “silenced”. Your 1st amendment rights aren’t being violated, it’s you violating the rules and civil code of conducts that got you penalized. There’s a difference.
You’re also not immune out in person either. Like getting up in people’s faces in places like Wal-Mart about how you feel about someone or whatever.
Freedom of Speech also covers the fact that you can have open opinions and expressions towards any political figure as well.
The speed of light from point A to B.
Seriously.
For complicated reasons every measurement of the speed of light is bouncing off something back to the source. It might be very different each way, and we can only average them.At the same time, though, every time the speed of light has been measured, it has always been the exact same, unless something was being done to it to cause it to slow down.
So we are highly confident that the speed of light in vacuum is a exactly equal to 299,792,458 meters a second.
Right. But it could be faster in one direction than the other, and we don’t have a way of knowing. It’s probably not… But maybe 🤷♂️
Light doesn’t really have a direction.
It only appears to have a direction over time, from the viewpoint of an external observer.
From the point of view of the photon, it exists as an atomic emission, immediately hits its target, and is reabsorbed.
So there is no back for it to come from.
From the perspective of light, time itself doesn’t exist, so speed and distance don’t exist. But we know they do.
