Dark matter has mass, but cannot be detected with electromagnetic waves like x-rays. It’s believed to be made up of subatomic particles we don’t know about yet
A bit from wikipedia:
Because dark matter has not yet been observed directly, if it exists, it must barely interact with ordinary baryonic matter and radiation, except through gravity. The primary candidate for dark matter is some new kind of elementary particle that has not yet been discovered, in particular, weakly-interacting massive particles (WIMPs).
There's also the theory that space itself can have an energy state, known as the cosmological constant.
It got a lot of flack, even Einstein disliked it. But it's actually recently started to pick up some speed as a possible option. (And it's totally not my personal pick of the two, totally.)
Someone remind me to look into that quantum teleportation thing tomorrow when I have more than 3 brain cells awake. It's always fun to have my hopes dashed that that's becoming a reality. Informative though.
Right so I did some reading, and after getting through the sci-fi nonsense regarding what it can be used for (one of the articles equated it to Star Trek "beam me up, Scotty!" tech, seriously), I think I have a fairly good understanding of what it means this time. Also I got to learn what a "qutrit" is, even if I still don't know how to pronounce it!
Basically, as with every other advancement in quantum entanglement, we still haven't perfected the transmission of information, with data being "sent" with roughly 75% accuracy. The big part of this development is the first time we have transmitted anything other than a qubit (quantum particle that can be in both a 0 or 1 state simultaneously). The qutrit is a similar particle that can be in a 0, 1, or 2 state at the same time.
The implications of this are
A) a better understanding of how quantum teleportation works with varied particles.
B) potentially greater quantum computing power as larger volumes of information could be sent at on
ce via the 3 states.
C) a redistributable "complete toolbox for teleporting a quantum particle intact" according to one of the researches.
D) a potentially upgradable system to allow the use of ququarts, a 4 state particle.
so comparable to most other advancements, this one is relatively large in terms of broadening our knowledge of both quantum computing and entanglement, and "will pave the way for quantum technology applications in high dimensions, since teleportation plays a central role in quantum repeaters and quantum networks."
Pretty neat stuff.
Saucies
because i'm a layman pleb.
