Always Feeding, Never Filled
Science brain teasers require understanding of the physical or biological world and the laws that govern it.
I can be born of a star, but it must be ultimately large.
This can only be so, if the fuel has been discharged.
I can be born in a merging, but my parents will be killed,
I'm always found feeding, but I can never be filled.
I'm the center of galaxies, so my nature is bestial.
I'm gravity intense, and in these clues I'm celestial.
Answer
A black hole.
A celestial object of such extremely intense gravity that it attracts everything near it and in some instances prevents everything, including light, from escaping. It's only those stars greater than three times the mass of the sun that become black holes upon collapse. There are two main processes constantly going on in massive stars. Nuclear fusion which tends to blow the star's hydrogen outward from the star's center and gravitation which tends to pull all hydrogen back in the direction it had come. These two processes balance one another until all the star's hydrogen is exhausted, allowing gravitation to take over. Once gravitation dominates, the star becomes unstable and starts to collapse. Once the star starts to collapse, it does not stop, and the star and ultimately its atoms will cave inward upon itself, resulting in the formation of a black hole. In addition, a collision of two older black holes or two neutron stars will also result in the creation a new black hole. Astronomers have also recently learned that the center of our Milky Way galaxy harbors a black hole and have found three other galaxies that also each harbor a black hole as well.

| I think the answer was a little long winded but it was a good fact i really know nothing about black holes. |

| I found the explaqnation of the answer more interesting than the riddle. But, neat thought! |

| "I'm always found feeding, but I can never be filled."
That gave it away... But it's nice to see an easy science teaser that I actually know the answer to once in a while! |
