They Grow Quickly


Wondrous Kea first reported this photo of a dust disk surrounding star Beta Pictoris. The picture was made by the European Southern Observatory's Very large Telescope (VLT). The star, barely 12 million years old, is already forming planets. Present science can not explain how planets form so quickly.

This may indicate the hidden influence of a Black Hole. The Big Bang probably created billions of tiny holes. If some of them were caught in a protoplanetary disk, their influence would cause planets to form quickly from dust as observed. Black Holes have the ability to seed formation of stars, gas giants, and even smaller objects.

From Space.com: A new study using data from both telescopes at our Keck Observatory looked at 15 young stars and their protoplanetary disks. The planets of these baby solar systems also appear to form very quickly. Someday Black Holes could be seen as ubiquitous. The planets and solar systems that support life may not have formed without their influence. Without Black Holes, dust could not accumulate into planets or stars.

After stars are born they usually retain clouds of leftover material around them that condense into rings called protoplanetary disks. Over time, the gas and dust in these disks clump together under the pull of gravity to build planets (Clara Moskowitz).

So, gravity itself is the reason for accumulation? Why we need black holes? How they are formed in the planet formation process?

Do you mean that a black hole (or holes) are located inside Earth (and our Sun as well)?

If there are black holes inside stars (and galaxies), how it is possible that the expansion of universe is accelerating?

Thanks for the kind words. Such a beautiful picture! It still boggles my mind that we can see things like this.

Old science can not explain how dust particles can accumulate into planetesimals. If particles collide at orbital velocities, they will ricochet rather than stick together. To start the process, you need a little Black Hole.

"If there are black holes inside stars (and galaxies), how it is possible that the expansion of universe is accelerating?"

Look at previous post Weak Evidence, and don't believe everything you read in press releases.

Kea's sense of wonder about the Universe is to be admired!

I read about a theory that the sun doesn't shine because of nuclear reactions, but because of magnetic fields generating the warmth. That would be a little black hole?

Lately I have tried to understand the zero point. Also that could be seen as a very, very tiny black/white hole, or a wormhole. It is the magnetic field change that is important, or how the force come forth.

So these black holes can be very common, but usually shortlived.

As above, so below :)

Hidden dimensions, branes and warped passages are fascinating mysteries of the universe:

So are warmholes

and the tiny black holes as well, if they really exist in connection of the above theoretical reasoning, and in the formation ( quick accumulation) exoplanets from gas and dust.

What about mini-black holes:

”Some physicists have made an even more startling prediction about the LHC: that it is energetic enough to create mini-black holes. Mini-black holes are being created around us anyway.”

Black bodies (dark matter) have been observed, but what about dark energy (antigravitation)?

Picture of Today (July 3):

http://antwrp.gsfc.nasa.gov/apod/astropix.html

Infrared observations from European Southern Observatory telescopes subsequently detected a source in the clear zone, now confirmed as a giant planet orbiting Beta Pic. The confirmation comes as the planet is detected at two different positions in its orbit. Designated Beta Pictoris b, the giant planet MUST HAVE FORMED RAPIDLY as Beta Pic itself is only 8 to 20 million years old.
