Luminal used in a sentence

Luminal in a sentence as a noun

And the energy transferred by an impact with a piece of dust at luminal speeds

But if it could be useful as an efficient sub-luminal drive, that would be cool and worth pursuing.

My first thought was that I wonder if this might be a simple case of super-luminal group velocities or something similar.

Coatings won't help this problem unless you can somehow change the shape of the crystal to fit through the slit OR get it to cross into the renal luminal space via transcytosis or excreted more efficiently in the biliary tree. All difficult propositions.

> A non-local value is any value which can impact things at super-luminal speed Ah. Those are ruled out by relativity. If you can send information faster than light, then you can send information backwards in time and violate causality.

It's just that when the wave goes from sub-luminal to super-luminal it creates some signal, and when it goes from super-luminal to sub-luminal it creates another signal, that looks like the other signal running backwards. It looks impressive, but it is another linkbait.

Traveling to this destination at sub-luminal speeds would become practical for the onboard travellers. Ultimately, from the ship's frame, it would be possible to reach anywhere in the visible universe, before the ship has time to accelerate to light speed.

That also sounds like a recipe for maintaining causality as in the faster you are trying to go to more you’ll expand space time maintaining the luminal speed limit from the point of view of an observer.

All you need is interstellar travel at sub-luminal speeds, and a life span that makes it reasonable to undertake the journey from your home-world to the Earth. Say, a species with a lifespan of ten thousand years living in a planet 10 light years away, that can travel at half the speed of light- it would take them 20 years to travel here and 20 to go back.

When experimentalists announced they had discovered super-luminal neutrinos, everybody reacted exactly like all the amateurs here are saying we should: Explore potential theoretical ramifications while being aware that it's most likely measurement error and encourage further study until we're sure. Not so for the EMDrive.

The areas attracted artistic types, ravers, communes and the sense of existing, living in luminal states where structures of power, churches, local government, economic development were strangely absent from the population of oddballs and irregular who could rent a 4,000 square foot loft in a former printing plant for $1,000 a month. No social services, grocery stores, schools or other symbolic anchors of traditional communities were present.

I also don't understand how exactly such treaty would be negotiated given the distance and luminal or subluminal communication speeds in a relativistic universe. I'm still of the opinion that the best answer to "where's everyone" is that while life isn't rate, intelligent life is, and technological intelligence is even rare at least at any given moment, and it's quite likely that there are sufficient great filters ahead of any civilization that evolves to make any coexistence of technological civilizations within a given galaxy a rarity.

That is, when you observe one half of the entangled pair there is not a super-luminal speed transfer of information because the information was already available to the other half of the pair at the time that they were entangled; it will become the necessary state upon observation of its pair because that is what is necessary in the future.
