Starship Asterisk*

Using the world's largest camera (570 megapixels) developed by scientists at the Fermi Lab, the Dark Energy Survey beginning next year (http://en.mercopress.com/2011/08/25/world-s-largest-camera-to-survey-300-galaxies-from-an-observatory-in-north-chile) will look back in time (6 to 7 billions years ...

In reply to Is "space" uniform across the universe? Chris Peterson wrote I'm not sure what exactly you mean by that. Certainly, there is no indication that any regions of space have different properties than others, or that physical laws are different in different places. Scientists have d...

Thank you all for very enlightening replies. Kind of make sense (for now) , specially with this view of the "observed" universe within 1 billion light years from earth. http://www.atlasoftheuniverse.com/superc.html Our Milky Way is in the Virgo cluster. I wonder how the view would appear o...

Then I am back to the original question, where is the center of gravity of the visible universe?

Chris Peterson wrote Both theory and observation suggest that the Universe is unbounded and isotropic on a large scale. Therefore, there is no center of gravity. Regions causally connected to others interact via gravity or other mechanisms, of course. But those should be seen as local interactions (...

Clumps of matter (visible and dark) in space, from the earth and moon to all the super galaxy clusters (at least two super super clusters), are observed(?) to be bound by forces (known and unknown) orbiting one another in their common center of the push and pull of these forces (dark energy and grav...

Mass is a basic property of all matters (baryonic and non-baryonic). Gravity is also an observed property of all matters. Taken together, they make all matters in the universe to attract and form structures from the atomic to the galactic levels. Between all matters, from the atomic to clusters of g...

I don't follow your suggestion that the change in ratios of the components of the total energy budget carries an implication that dark matter influences itself. It has been suggested that all organic matter decays and have a half-life. http://www.nature.com/nature/journal/v194/n4827/abs/194464a0.ht...

WMAP Measurements The Wilkinson Microwave Anisotropy Probe (WMAP) was designed to achieve more precise measurements of the anisotropy in CMB. Within the framework of the "Lambda-CDM Model" of the universe, the WMAP data indicate that the age of the universe is 12.73 ± 0.12 billion years ol...

Whether a merged black hole will have jets, however, depends on the medium around it. If there isn't enough material to support an accretion disc, there won't be any jets. Even if one or both had accretion discs before the merger, the collision itself could disrupt or even absorb that material, whi...

What happens when a black hole gets close to another black hole? Is there such a phenomenon as multiple black holes system? If black holes eventually eat each other, then one can imagine a single super massive black hole with two opposite super long and expansive jet streams. Is it inconceivable to ...

You are assuming that the ejection occurred in one big explosion similar to an exploding firework. What if there were multiple explosions at different cosmic time intervals. Would the star positions relative to its axis of rotation and its orbit when these explosions occurred have contribute to the ...

Clumps of matter (visible and dark) in space, from the earth and moon to all the super galaxy clusters (at least two super super clusters), are proven to be bound by forces (known and unknown) and are orbiting one another in their common center of mass. The observed red shifting of visible matter in...

Engineers design banks on winding roads and race tracks to prevent vehicles travelling within "safe" speed from flying off the road. Similar results can be achieved if upon speeding through the winding portion of the road, vehicles are tethered to an imaginary rope. In the universe, the pu...

How does one get to the saved draft version to read, edit or post?

As planets and comets revolves around the Sun in their respective orbits, do they respectively travel at a constant speed? As they pass in proximity to each other, does gravity have any sling shot effect?
By extension, do stars and galaxies (and clusters) behave the same way?

“The implication is that we did not form out of the same solar nebula materials that created the Sun – just how and why remains to be discovered.” ----------------------------------------- By extension, the Sun and the planets may not have been created at the same time, the Sun was first and then th...
