Black Hole Size Comparison

A black hole is a region of spacetime exhibiting gravitational acceleration so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of the region from which no escape is possible is called the event horizon. Although the event horizon has an enormous effect on the fate and circumstances of an object crossing it, no locally detectable features appear to be observed. In many ways, a black hole acts like an ideal black body, as it reflects no light. Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe.



So this is your time! Use it wisely my friend! Give yourself that chance of honest communication and the intimacy and deepening connection which can come out of it. Sun in Sagittarius. With the transition of the Sun into the next sign of Sagittarius we will move into a more extroverted and expanding flow of energy with many ideas and inspirations. The team discovered that the Methone's density would be about 300 kilograms per cubic centimeter. That amounts to less than a third of the density of water, making Methone less dense than any other known moon or asteroid in our Solar System!
