# phys: the strange world of quantum mechanics

<< In the normal world, an object such as a baseball can only be in one place at one time. But in the quantum world, a particle such as an electron can occupy an infinite number of places at the same time, existing in what physicists call a superposition of multiple states. >>

<< in the quantum world, two individual particles, such as photons can be entangled, such that the mere act of sensing one photon with a detector instantaneously forces the other photon, no matter how far away, to assume a particular state. >>

<< evidence is mounting from the world of plant physiology that some biological processes that rely on quantum superposition occur at normal temperatures, raising the possibility that unimaginably strange world of quantum mechanics may indeed intrude into the every day workings of other biological systems, such as our nervous systems. >>

<< Evolution, in its relentless quest to engineer the most energy-efficient life forms, appears to have ignored physicists’ belief that useful quantum effects can’t happen in the warm, wet environments of biology. >>

davanti a una immagine di "enzima allosterico" qualsiasi bravo scientist sa immediatamente con cosa avra' a che fare: avra' a che fare con il caos, vale a dire con oggetti che possono generare dinamiche senz'altro confinate purtuttavia bizzarre, jazz, funky, fuzzy; invece davanti a concetti quali i due citati sopra (superposition, entanglement), e gli ipotetici effetti immaginabili all'interno di strutture biologiche, neurobiologiche, informatiche, ho idea che chiunque potrebbe sentirsi vagamente disorientato (qui si sottolinea "vagamente") ...

# gst: apropos of singularities of space-time intent on sucking up all the matter around them, a reiteration by Fiona

<< For our Sun, that means it would need to be crushed down to the size of a small town in order to become a black hole. And Earth would have to be squashed to roughly the size of a peanut. >>

<< Check out the video   https://youtu.be/QgNDao7m41M   to see just how big and massive black holes can really get. Even if you think you know, you don't. Trust us. >>

<<  A version of this article was originally published in November 2016. >>

# gst: images of hypothetical realities; expansion of bubbles in extra dimensions (of tiny, vibrating "string- like" entities)

<< According to string theory, all matter consists of tiny, vibrating "string-like" entities. >>

AA << proposes a new structural concept, including dark energy, for a universe that rides on an expanding bubble in an additional dimension. >>

<< The researchers also show that expanding bubbles of this kind can come into existence within the framework of string theory. It is conceivable that there are more bubbles than ours, corresponding to other universes. >>
