Fuck it, let's assume we can build jump gates.
Let's say they're just big enough to send a tiny unmanned drone through.
I hop into my space ship and accelerate with a conventional engine to 86% of light speed.
No violation of physics needed, just shitloads of energy.
I fly to another star, which takes 10 years from earth's point of view.
Due to time dilation at 86% light speed, time in my space ship passes half as fast as on earth.
If someone on earth had a strong enough telescope, they could look at a clock on my ship and see that it ticks half as fast as the clocks on earth.
But in my frame of reference, earth moves away from me at 86% light speed.
So if I look at earth through a telescope, I see that the clocks on earth tick half as fast as mine.
There isn't a universal time. Time is always relative to speed and this is no problem when the reference frames are separated.

I arrive at the star, look through my telescope and see that 5 years have passed on earth.
I activate a jump gate and send the drone through with a message. It arrives on earth instantly, 5 years after I left.
But from their reference frame, they could see my clock ticking only half as fast as theirs.
After earth's 5 years, only 2.5 years have passed for the space ship they see.
They activate their jump gate and send the drone back with a reply.
It arrives instantly at the star, 7.5 years before my space ship gets there.

This is why FTL travel isn't and will never be possible. Even with tricks like jump gates or wormholes, it creates time paradoxes.

We could maybe eventually load up multiple asteroids with building materials, frozen embryos, a self-healing nanobot factory, blueprints for building artificial breeding chambers and humanoid robots, controlled by an AGI to serve as educators, and send them off to nearby stars.
Upon arrival on suitable planets, the systems wake up and jump-start colonies.
After several hundred or thousand years of development, those colonies could build their own seeder asteroids, kicking off an exponential progress.
If every colony in turn colonizes 4 new systems within 10,000 years, we could theoretically colonize every suitable star system in the Galaxy after 200,000 years. At a very reasonable ~0.1% of light speed.

But we would have zero control over the colonies, no shared culture, no trade, hardly any meaningful communication. So there would be very little benefit to it, and knowing human nature, a war of total annihilation would be likely as soon as suitable planets get scarce.

Intergalactic travel will never be possible for humans.
The nearest galaxy is 2.537.000 light years away. By the time we get there, we wouldn't be humans anymore.

Pretty sure both of them are LLM-generated

If Africa was the same continent as Asia, it should be easy to walk across.
But you literally can't. The only connections are a freeway bridge (currently closed), a railway bridge, a road tunnel and ferries. And geologically, an ocean is in the process of opening up in between.

As for Europe, it doesn't even have its own continental plate.
It's less of a continent than India.

Behold the perfect map:

  • equal area projection
  • rectangular map shape
  • rectangular coordinates
  • zero distortion along equator
  • centered on date line, not some irrelevant Bri'ish town
  • aspect ratio (width/height) is π
  • developed by a mathematician

Show map

(Bonus: England is cut in half)

The dueling minigame goes into muscle memory, as well.
And it uses the same timing, mechanics and keys as the dancing minigame.

Microsoft Word defaults to saving in its own file format .docx, instead of the ISO standard for word processing (.odt)
To allow others to collaborate, Microsoft publishes documentation on how Word builds and opens .docx files.
So LibreOffice would have no trouble opening .docx files with all formatting perfectly intact.
If Microsoft actually followed their own documentation when building Word. Which they don't.

The other issue is that people use Word files to share documents with extensive formatting and embedded images in the first place, instead of converting them to PDF or using typesetting software.

Wurde gemacht.
Aber es gibt im B2B keinen Käuferschutz und kein gesetzliches Rückgaberecht, weil der Gesetzgeber davon ausgeht, dass beide Vertragsparteien gleich stark sind und keine schützenswerten persönlichen Grundrechte betroffen sind. Also gilt Vertragsfreiheit.
Wenn du als Unternehmen bei der Einrichtung des Volume Licensing Centers zustimmst, dass Käufe über das Portal bindend sind, kommst du da nicht raus.

Bei meinem letzten Arbeitgeber (IT-Systemhaus) hat ein Kollege im Microsoft Volume License Center mit einem einzigen falschen Mausklick Lizenzen für 16000€ auf den falschen Kunden gebucht.
Er hat es dann innerhalb der nächsten Woche tatsächlich geschafft, sich bei Microsoft solange durchzutelefonieren, bis er den Chef-Entwickler des Licensing Centers am Apparat hatte. Der hat ihm dann bestätigt, dass es keine Möglichkeit gibt, das zu stornieren, umzubuchen, oder die Lizenzen auf einen anderen Tenant zu übertragen.
Die Funktion war geplant, aber noch nicht implementiert.
Und wenn die Firma nicht zahlt, behält Microsoft sich vor, den Account zu sperren, was ca. 200 Kunden arbeitsunfähig gemacht hätte.

(Der Chef hat dann angefangen, Alternativen zu Microsoft zu recherchieren, die er Kunden anbieten kann. Aber es gab nichts was die Kombination von Outlook, Exchange und AD zufriedenstellend abbilden konnte.)

If the cops actually had anything real on him, they could get the warrant over the phone while stalling you at the door, or even storm your place and get it later.
And even if they don't get it, no cop can get in trouble for the raid if they "suspect" you might destroy evidence, and anything they find can still be used in court.

It completely invalidates your 4th amendment rights, but congress felt this was needed to protect you against "terrorists" 25 years ago.

I just don't get it.

According to the theory of special relativity, nothing can ever move faster than light speed.
But due to the expansion of the universe, sufficiently distant stars move away from us faster than the speed of light.
And the explanation is...that this universal speed limit doesn't apply to things that are really far away?
Please make it make sense!
