  complex numbers are just numbers in a plane instead of a line. saying you don’t believe in i is like saying you don’t believe in “up”

  the speed of light expressed in units of distance per time, is a dimensionful quantity so it probably doesn’t mean anything to say some theory does or does not predict a value for it. The value is entirely determined by how big you choose your yardsticks and sundials to be, which is arbitrary convention.

  It is only meaningful to talk about theoretical predictions of the values of constants if they are dimensionless, like the fine structure constant.

  However relativity does suggest as a natural point of view that space and time are just orthogonal directions in a unified spacetime. In this point of view, relativity gives you the option of measuring your timelike and spacelike coordinates with the same yardstick (which you may still choose arbitrarily). And then relativity does predict its value. It’s 1. No units.

  Ok but photons don’t change direction either. Treating photon scattering as an individual particle accelerating due to an applied force, well that’s just not a correct description of how perturbative QED models photon interactions.

  The fact that light cannot change speed is one of the core axioms of relativity

• ⁨Comment⁩ on ⁨Speediest little fella.⁩ ⁨⁨1⁩ ⁨year⁩ ago⁩:

  Photons cannot accelerate

  but the encryption keys are not stored on the 1password cloud systems

• ⁨Comment⁩ on ⁨1Password discloses security incident linked to Okta breach⁩ ⁨⁨1⁩ ⁨year⁩ ago⁩:

  1password user data is encrypted, right? so even if a hack had allowed a bad actor access to user pw databases, it’s not like they would’ve just scored everyone’s passwords… right?

  Sadly true. As a nose cutter I will say that I have found the transition from Twitter to mastodon far more painless than Reddit to lemmy

  Bro it was just a chance to improve your grammar. It was offered in good faith. If you don’t want it that’s of course your prerogative. But there’s no need for rudeness and hostility.

  Of course in going that route you’ve demonstrated an aspect of lemmy that may be an answer to your question.

• ⁨Comment⁩ on ⁨What is going on with the number of active users?⁩ ⁨⁨1⁩ ⁨year⁩ ago⁩:

  I would like to invite you to increase your mastery of the English language by learning about all the tenses. With a judicious choice, (I would recommend a pluperfect progressive), you can avoid writing confusing and self-contradictory things like:

  Lemmy’s number of active users has been decreasing for the last month. […] the number has been on an upward trend for the last 6 months

• ⁨Comment⁩ on ⁨⁩ ⁨⁨1⁩ ⁨year⁩ ago⁩:

  So is there a place where we can access our lemmy.fmhy.ml accounts right now?

• ⁨Comment⁩ on ⁨⁩ ⁨⁨1⁩ ⁨year⁩ ago⁩:

  “Every right”? No. They have the power to do so but that doesn’t make it right. They sold those domains fair and square. Contracts were signed.
