Interesting way to look at it, but I still dont see where the force is acting on the object going through the portal. The object is not in motion and will stay in that state unless something acts upon it, so where is the energy coming from to act on the object?

The portal is a hole. The hole is moving. The conservation of momentum is the hole moving as it continues to move along the track. If the people start moving, where does that momentum come from?

Imagine a tennis racket with no strings. Two portals are stretched across the space the strings would normally be, back to back, one orange one blue. If you threw a ball in the air as if you were going to serve and swung the racket, the ball would pass straight through the portals as if they weren’t there and would fall straight down due to gravity. The ball maintains its conservation of momentum, and the tennis racket holding the portals also maintains its conservation of momentum as it swings through the air. There is no force applied by a hole.

Its just a hole though. If you have a tennis racket with no strings and swing it over something stationary the object doesnt move

Absolutely not. A company gets to choose who it hires and fires though, and if you act in a way contrary to their rationale then they have no obligation to keep you around.

There’s nothing wrong with getting an explicit photorealistic tattoo of a vulva on your forehead either, but your boss at the childcare centre might not like it and you’ll probably lose your job.

They obviously knew her twitter prior to offering the job and were actively monitoring it. The NASA guy doesnt just go around telling people to watch their language in tweets. They were keeping an eye on them, and they fucked up.

Best practice in 2023 is a simple, sufficiently long but memorable passphrase. Excessive requirements mean users just create weak passwords with patterns.
[Capital letter]basic word(number){special character}

Enforcing password changes doesnt help either. It just creates further patterns. The vast majority of compromised credentials are used immediately or within a short time frame anyway. Changing the password 2 months later isnt going to help and passwords like July2023!, which are common, are weak to begin with.

A non expiring, long, easily remembered passphase like
forgetting-spaghetti-toad-box
Is much more secure than a short password with enforced complexity requirements.

Are we really starting this shit here?

Everything on the internet is a repost. Calling it out adds nothing worthwhile to the conversation and just derails any conversation.
