Daffy Duck Wit The fact that smaller objects entering a large objects
gravity field start taking a curved path helps the capture theory. A closed curve and its in orbit. Over time the orbit gets rounder,and rounder. This has been shown to us. When we hit that large comet the explosion had nothing going into orbit,only fine dust going 100s of miles into space. That has to tell even a duck head something Bert |

(honest question) The matter in black hole accretion disks lose orbital energy via frictional heating. Objects passing by at moderate distances will not be captured unless they happen to encounter other objects along the way and have their trajectories altered to intersect the hole or its accretion disk. Near misses can tear apart objects due to tidal stresses. Of course, the great gravity of supermassive black holes causes everything in its vicinity to orbit at relatively high speeds, so that the encounter and collision rates are higher, too. |

What that man said ^ ;-) You can also factor in the increasing deviation from Newtonian mechanics with SMBH as well. There's a greater dwell time near periastron as well for any object coming in close due to the extra term in the gravitational potential - the term Mercury proved so well.... ;-) -- Got mail? I did ;-) Three and counting. Got proof? Not yet, still waiting. |

Future life to Orbit White Dwarfs
Double-A My critics are just jumping on a medium stars lifecycle when
it balloons out to be a "red giant" I'm going with the spacetime when the sun looses this outer layer to space and what is left is a white dwarf. that is destined to give of photons for another 100 billion years. White dwarf stars are part of binaries. Have a picture of a white dwarf that is only the length of are solar system away from its companion. There is that famous "Algol system" I have always had the idea that a white dwarf creates this condition.(does the eclipse) Double-A fact is a white dwarf can last 10 times longer than my age for the universe. Like old soldiers they just fad away. Life needs heat,and white dwarfs take their time to cool. Bert |
