Is there an upper limit to black hole masses ?
We make a case for the existence for ultra-massive black holes (UMBHs) in the Universe, but argue that there exists a likely upper limit to black hole masses of the order of M ∼ 1010M⊙. We show that there are three strong lines of argument that predicate the existence of UMBHs: (i) expected as a natural extension of the observed black hole mass bulge luminosity relation, when extrapolated to th...
متن کاملIs There an Upper Limit to Cardiopulmonary Bypass Times?
Background: There are no safe operations in cardiac surgery. Every operation can possibly go wrong. We therefore retrospectively evaluated all cardiac operations lasting more than 300 minutes of bypass time at our institution to evaluate outcome and factors relevant for perioperative mortality and morbidity. Methods: We retrospectively included patients receiving cardiac operations or operation...
متن کاملThere Is an Upper Limit of Chromosome Size for Normal Development of an Organism
A clearly definable upper tolerance limit for chromosome arm length has been found. As a rule we postulate that, for normal development of an organism, the longest chromosome arm must not exceed half of the average length of the spindle axis at telophase. Above this length, fertility and viability of the carrier individuals become severely impaired due to increasingly incomplete separation of t...
متن کاملIs there a speed limit for thermalization ?
The purpose of this note is to describe how a model [1] of interacting spins is related to recent ideas in quantum gravity and the foundations of quantum statistical mechanics. These surprising connections underscore how ideas in seemingly disparate areas of physics can influence and inform one another. Our intention is not to motivate the spin model through the experimentally-accessible system...
