Hungry Black Holes
Nearby galaxy clusters CL 0542-4100 and CL 0848.6+4453 imaged by the Chandra X-ray Observatory. Low energy X-rays are in red, intermediate energy in green, and high energy in blue. A study in the July 20 issue of Astrophysical Journal Letters indicates that Black Holes in older clusters are 20 times more active than those in younger clusters. The early Universe was dominated by energetic quasars and Active Galactic Nuclei (AGN). As they matured and their fuel was used up, these objects evolved into galaxies like our Milky Way.
The Big Bang created billions upon billion of Black Holes. Because the speed of light was higher, primordial Black Holes formed in a variety of sizes. The big ones formed the seeds of clusters and galaxies. Our galaxy formed around a Black Hole like the whirlpool around a drain. Supermassive Black Holes don't die, they just fade away.
Tiny Black Holes could exist within planets, even Earth. This one is too tiny to suck us up, but the tiny amount it does eat keeps Earth's core warm. This heat causes earthquakes, volcanoes and the formation of islands. The Black Hole also powers the magnetic field that protects us from the radiation of space. Our planet and life would not exist if not for a Black Hole.
Speaking of hunger, the Monterey Bay region has been invaded by 2-meter jumbo squid that munch on the local fish population. Previously jumbo squid were only found in warmer Pacific waters. Their appearance near the Central California coast may be a result of Earth's changing climate. Earlier this month in Tasmania, a rare giant squid measuring 8 metres washed ashore near the town of Strahan. When Earth's climate changes the species adapt, a squid pro quo.

just found this, love your style. Has planetary formation been simulated by computer ie. Gravitational attraction of random matter/gas vs with a
baby blackhole seed? possible big time difference in age to adulthood?
Thanks dc, I was in Washington just last week. Planetary formation has been simulated, but unless gas particles have the mass of mountains they simply will not stick together. Simulations also can not explain why Earth and Venus have circular orbits, which is an additional mystery. Tiny Black Holes explain all this and the quick formation of planets too.
tiny black holes! gm=tc^3, cosmology is simply inspiring... (even in MN:)
So Venus, which has much less of a magnetic field doesn't have a black hole at it's center. So one can say that Earth sized planets can certainly form without any small black hole aid.
Or is this a mischaracterization?
Ten years ago, i didn't believe in anti-gravity. Now: dark energy is replusive. Yet it will take a bit more evidence to swallow tiny black holes inside planets. Or do i mean tiny planets swallowing black holes?
Actually Venus probably has a Black Hole, which explains why it has vulcanism. There is little magnetic field because the Black Hole does not rotate. That helps explain they mystery of Venus' angular momentum, why it appears to spin backwards.
Stephen, you may have been right all along about anti-gravity. I recommend that you not buy stock in "dark energy." Even if DE existed, it would be too diffuse in Space to have any conceivable use.
I have often wondered how space dust gathering together could produce enough mass to have an effect upon fast moving particles via gravity to ever form anything more than a cosmic dust bunny. A small singularity makes more sense.
With more now 'thinking of a prince'... if we have a "personal" blackhole, what's going on near it? how frequently? whats detectable? It apparently is 'manageable', and even somewhat friendly!
Black Holes are friends. A typical mini-hole has mass of 10^11 kg. If you were standing one meter from it the gravitational pull would be only 2/3 what you feel at Earth's surface. Detecting them would be difficult unless you were extremely near. Many could be orbiting within our solar system right now
This was fascinating to read. As for me space secrets are the most captivating and exciting mysteries ever in the world. I can't get enough of them Thank you so much for your post!
