put a machine that releases poison only when the particle is in the a state in a box and that we also put a cat in it until observed the machine would simultaneously release the poison and not release the poison this means that until observed the cat would be both alive and dead this would obviously work only if we don't consider the cat or the machine as observers twin paradox according to Einstein the faster you move through space the slower you move through time if your identical twin became an astronaut and went on a spaceship that

traveled at the speed of light you'd be some years older than him when he returned friendship Paradox on average your friends tend to have more friends than you do this happens because people who are social and have more friends are more likely to be your friends friends Raven Paradox if you wanted to confirm that all Ravens are black finding a black raven supports your claim but the Paradox suggests that also finding something that is not a raven and not black such as a green apple supports your claim temperature Paradox if the temperature is 90 and
