If time is effected by proximity to mass, are the planets at the center of a galaxies core progressing faster than we are out here on a spiral arm? And if yes, does it all equal out upon travel and contact? If no, how far are we behind?

Oh all right then. Time passes slower at a point observed from somewhere higher in a gravitational field. Thus time will pass a little slower on a planet of the same size much nearer the galactic centre as seen from Earth. Not I imagine very much though. |

Thanks Michael Roberts! I thought time went faster near higher mass/gravitation? The speculations about time time differentials from earth time and a manned space craft sent to alpha centauri and back was pretty great. Was your comment about the differential being small relative to a big picture? Thanks again.

Thanks Michael Roberts! If I have it right, the clocks will run slower in the high mass area than in the low mass area. Just as they run slower on a very high speed spacecraft. BOINC WIKI |

Thanks John McLeod VII, Can anyone else confirm? "Be who you are and say what you feel, because those who mind don't matter and those who matter don't mind." - Dr. Seuss |

In Sagan's "Cosmos," there was a scene where a young man goes for a moped ride around his sleepy Italian town. He goes near the speed of light. When he returns, he finds the younger brother he left to wait for him in the center of town is now 70-80 years old. Of course, part of my letter to Sagan when I was an 8th grader was to ask why ... when the moped rider passes a woman hanging laundry on the outskirts of town ... the woman whips her head around to watch him whizzing by ... I asked why was she not instead coming out each day thinking: "When is that slow kid ever going to pass my house?" (See, I had this idea that the woman and the younger brother of the moped rider would be in the same temporal frame and stuff.) Capitalize on this good fortune, one word can bring you round ... changes. |

For her to see him pass at TSOL she'd have to be moving with him, or near to his speed to see him. Your right. No way she could have seen him pass. Probably a little comedy relief from the director... "Be who you are and say what you feel, because those who mind don't matter and those who matter don't mind." - Dr. Seuss |

Isn’t the concentration of normal (baryonic) matter at the center of the galaxy somewhat misleading? If I understand it properly, the galaxy is mostly evenly diffused dark matter, which reacts gravitationally with the galaxy like normal matter does but is otherwise invisible - that’s why stars on the outer regions of the galaxy circle the core at approximately the same velocities as further in. So wouldn’t local conditions (say, solar system scale) have a much larger effect that larger (galactic core) scales? On the other hand, if one were in a tight orbit just outside of the event horizon around the monster black hole that probably lies at the galaxy’s center, time dilation would come into strong effect. (Though, I suspect that consulting your clocks would be the least of your concerns at that point!) I'm just thinking out loud here...Darn, why is there never a theoretical physicist around when ya want one! Pure mathematics is, in its way, the poetry of logical ideas. Albert Einstein |

Interesting! I'll email a few Theoretical Physicists about it and see what they have to say. Dark matter is an interesting deal! Hawking overturned his old black hole theory. I'll have to have a look at his site about the progress of the new theory.

Interesting! Good grief, dude, never make the mistake of thinking that I have any idea what I'm talking about because I don't. All I know is the pap I read in pop-science books... Pure mathematics is, in its way, the poetry of logical ideas. Albert Einstein |

Interesting! I don't believe that. Interesting article: http://metaresearch.org/msgboard/topic.asp?TOPIC_ID=979 "Be who you are and say what you feel, because those who mind don't matter and those who matter don't mind." - Dr. Seuss |

<=== tutoring Kenzie ;) Good luck, my friend, but I am truly hopeless when it comes to math. I remember trying to study the calculus in high school. Mostly I remember vaguely appreciating that it was a beautiful thing, and I remember profoundly not understanding it. Pure mathematics is, in its way, the poetry of logical ideas. Albert Einstein |

Wow, We got bumped to the science forum. Anybody look in these forums any more? :) "Be who you are and say what you feel, because those who mind don't matter and those who matter don't mind." - Dr. Seuss |
