QUESTION. “Does the initial outflow of negative energy from the white hole continue for the entire lifetime of the white hole, increasing the mass of the white hole up to the original mass of the black hole when the bouncing shell of matter that formed the black hole emerges and the white hole disappears?” https://lnkd.in/dUKnus8 View in LinkedIn

GEOMETRIC CONTORTIONS. “It is not surprising that energy flow does not follow such a geodesic through the transition from the black hole to the white hole, where the geometry is changing rapidly from collapse to expansion.” https://lnkd.in/dUKnus8 View in LinkedIn

“PHYSICS is full of opposites. For every action, there’s a reaction; every positive charge has a negative; every magnetic north pole has a south pole. Matter’s opposite number is antimatter. And for black holes, meet white holes. Black holes are notorious objects that suck in everything around them. Famously, not even light can escape their awesome gravity. White holes, in contrast, blow out a constant stream of matter and light – so much so that nothing can enter them.” https://lnkd.in/djSRsBX View in LinkedIn

These seemingly fragile gems withstand storms, dirt, predators and pollution, and are tough enough to migrate long distances. View in LinkedIn

LIKE GENETICS VS EMBRYOLOGY. “Synthetic biology presents a challenge to traditional accounts of biology: Whereas traditional biology emphasizes the evolvability, variability, and heterogeneity of living organisms, synthetic biology envisions a future of homogeneous, humanly engineered biological systems that may be combined in modular fashion.” https://lnkd.in/dhkrmJx View in LinkedIn

SO ENDS this first of two weekends on the cunning strategy of the bacteria Wolbachia which has enabled it to colonize half of the insect species in the world. The ability of symbionts and parasites to enact sophisticated strategies on their hosts makes one suspect that more than chance is at play, but when nature gambles at such high rates over geological time, even slim probabilities can become realities. It is a game of sheer numbers against the odds of chance. View in LinkedIn

ENTROPY LAW. “The discovery of Hawking radiation showed that a black hole radiates like a black body and has a thermodynamic (Bekenstein-Hawking) entropy proportional to the area of the black hole horizon.” https://lnkd.in/dUKnus8 View in LinkedIn

“ENTROPY has played a central role in discussions of the evolution of black holes since before the discovery of Hawking radiation.” We took a very big dive into this topic. https://lnkd.in/dUKnus8 View in LinkedIn

DIMINUTIVE COUSIN. ‘The physical lifetime of the white hole…(is) much shorter than the lifetime…of a large black hole.” https://lnkd.in/dUKnus8 View in LinkedIn

QED. “The evolution of the white hole in Paper I is very simple. Its mass increases steadily as a function of retarded time due to negative energy flowing out across the white hole horizon, in a time-reverse of the evolution of the black hole. The white hole disappears when the rebounding matter shell emerges, leaving nothing behind. There is no significant flow of energy along the white hole hole horizon.” https://lnkd.in/dUKnus8 View in LinkedIn
