...is enough to give one a headache. I actually think I find the concepts easier to grasp than most, but they still make my brain go "Wait a minute."
This week, two experiments are enough to make us question reality:
1. Russian physicists teamed up with Swiss and American teams to, uh. Reverse time. Actually, they wrote a quantum algorithm that had that effect for a pair of qubits in a quantum computer. The point is to make quantum computing more accurate. It doesn't really reverse time, but rather cause a system to devolve (yes, that's right) from chaos back to order.
2. Heriot-Watt University had two scientists independently observe the same quantum state. As we know, when you observe the cat it becomes alive or dead. Except...one of the scientists saw a live cat and the other a dead one, or more accurately, they each saw the particle in a different state. This means objective reality doesn't actually exist at the quantum level.
Maybe that second one means that what we call reality is the consensus of all of our observations overlapping each other? Who knows.
Quantum stuff is just freaky.
