Please note that this website is currently a work in progress! Lots of interesting data and statistics to come.
Sabine Hossenfelder is one of my favourite scientists.
She has a charming accent, and explains interesting (to me) subjects from her field of work with just the right amount of detail for someone of average lucidity (like me) to understand.
I’m going to go out on a limb here with a crazy pov. The past does not exist. It would be too complex to maintain the info. Travel into the future also is impossible unless it’s in another dimension. Time “travel” violates the laws of thermodynamics. Matter and energy can only exist in the present. If you went into the past or future it would require a whole universe of mass and energy to create the experience. Also when you see sci-fi where humans “shrink” (Ant Man, Fantastic Voyage) it violates the law of conservation of mass. Mass volume is constant unless it is converted to energy. The volume can’t get any smaller because of how atoms interact with each other.
