So has that changed? Or is this just theory and modeling?
Imperial College London physicists have discovered how to create matter from light - a feat thought impossible when the idea was first theorised 80 years ago.
They didn’t discover it, as they say in the same sentence this is an 80 year old theory, rather they demonstrated it in a lab rather than observing it in nature. That sentence also makes it sound like this process may have been considered impossible until they demonstrated it in the lab, and that is just not true.
Plus this stupid site clipboard hijaacks. Feh.
How is it that some physicists seem to talk about results of modeling as if they were experimental results?
Particle colliders like LHC and it's progenitors all create matter as a fundamental part of their operation, but I guess they're classifying that as "energy" to matter not "light" to matter.
2) Say that the only way to test requires "slabs of gold"
I didn't see matter being consumed anywhere, did I miss it?
Anyway, obviously that's still science fiction but this at least opens the door.
Edit: You will get very small amounts of matter from energy. Small amounts of matter will mean very low thrust. Much better use of that amounts of energy is just collecting interstellar medium and accelerating it.
it would be way more useful to have a method to turn matter into light. this would be a fantastic low power space engine.
(not really an expert, but pretty sure about this)
That's really hard though, unless you use antimatter+matter. And then you'll have to produce the antimatter first, of course. And you're back to square one.
Well, not necessarily; if you could efficiently produce and store antimatter, that'd make a hell of an energy storage mechanism, and possibly make interstellar travel feasible. That's a HUGE if, obviously.
