If a Big ,Big Backhole is at the center our our Galaxy as is believed,why is Sun moving away & not sucked in?

Answer 1

I don't think that the sun is moving away. Think about the black hole as your bath tub drain. Everything in our galaxy, including our solar system, is swirling around the drain. It takes things farthest from the center of the drain (blackhole) much longer to travel once around the center. Eventually, everything will be "sucked in."

Answer 2

First, scientists believed that the universe would eventually just collapse in on it's self. In the late 1990's, astronomical observations began to suggest that the expansion of the universe is actually speeding up, meaning that eventually the gravity of the stars, planets, and everything else will keep expanding until every atom and molecule tears apart, causing space to be a dark empty void. But hey, this isn't gonna happen for about 10100000000000000000000000000 years - that's 26 zeros.

Answer 3

Well a black hole doesnt just suck everything in any more than our sun does; its nothing more than a massive gravity well. and just like how our moon has enough mass and inertia to orbit the Earth w/o crashing into us, the millions of stars and nebulas in the galaxy orbit that "black hole" because it simply doest have the gravitational power to draw all those bodies in. BUT, the sun and everything else isn't moving away; the only reason we can visibly see the black hole in a galaxy at all is because of the massive light and heat given off from all the stars that've been sucked in already.

Answer 4

The best way I've heard it put is this: If the Sun were replaced with a black hole the same size, the planets would still orbit around it as normal. Black holes don't have infinite power to suck everything in, because if they did, not just our Galaxy, but the whole universe would be sucked in.

Answer 5

A) Who says it's moving away?
B) Inertia and the influence of many millions of other stars that are much much closer.

Don't forget, the sun is 333,000 times more masive than the earth, yet the earth has circled it for 4.5 billion years now.

Answer 6

The Universe is still expanding. Outward not inward.

Answer 7

One, you probably mean a "black hole'. Two, black holes aren't large. Three, anything past the event horizon of a black hole and traveling away from it isn't influenced unduly or at all by the black hole.

Answer 8

Possibly the same reason why we exist at all.
