There are a couple of phenomena that are in principle impossible. These are:
* one thing can be in two places at the same time: [https://en.wikipedia.org/wiki/Double-slit_experiment the double slit experiment]
::very, very interesting: it is as if the electron (particle) is in two places at the same time. This ´collapses´ once the observer knows the location of the electron. Knowing something causes a collapsation??? So the wave pattern consists of uncertainty. We have never observed uncertainty before but in the double slit experiment it exists! The wave pattern only exists when we do not know what the location is of the electron. So we can say the electron exists in both slits at the same time but in both slits the electron exists with a certain uncertainty (probability), it is not certain it is in both places. Once we know for certain where the electron is, the whole phenomena disappears because probability has disappeared. How can things exist without 100% certainty? How can things be in two places at the same time? how can something collapse by our knowledge of it? Wow, this really feels as if we do not understand anything of existence itself.
::another bizar phenomenon: entangled particles. Researchers create so called entangled particles by using a crystal. When these entangled particles get separated, they are connected as if they are one. It doesn´t matter how far apart the entangled particles are separated. Distance is covered without any need for time to travel. In principle also impossible because there is always time necessary to travel any distance. Not in the case of [https://scienceexchange.caltech.edu/topics/quantum-science-explained/entanglement entangled particles]....
* time is not so universal
:: time, space and gravity are one complex thing I do not understand. Space is not straight, it bends and I think it bends stronger when there is more gravity. Time goes differently in differently places. A geostationary satelite has [https://www.sciencedirect.com/science/article/pii/S0273117721003288 a compensation] for the fact that 36.000 km above the earth, time has a different pace than here on earth.
* plants can learn. In principle impossible because plants do not have nerve cells, a spine, a brain; things we consider necessary for learning. However the [https://www.discovermagazine.com/planet-earth/a-string-of-unusual-experiments-claim-to-show-plants-can-think-few Monica Gagliano experiment] on mimosa pudica in a lift that suddenly bumps, shows that plants do learn

All things that seem very strange to us and that are for me an argument to dare to be open that things are actually different. I think and hope I will be surprised in a nice way when my body has died.
