Starship Asterisk*

The one question I was hoping someone could answer is: Is it possible that dark matter interacts in our universe gravitationally as the electro-magnetic wave phenomena we call light? The original reason this question came to my mind was that I could conceive light as “something” that was moving thro...

Let me guess. We would have seen a lot of Russians videotaping it - forever (at the edge of its event horizon) Just kidding. How about a gamma ray burst?

electrons and protons combined to form the neutrons Does this reaction need a neutrino too? But back to “Where’s the space?” again. I wonder to where the space left over from the electron shells goes? Guess that must be why the universe is getting larger. :lol2: Heisenberg certainly thought it had ...

At this scale, it is probably better not to think in terms of "substance" or "matter" or "material", but rather in terms of fields and field carriers. Fields and field carriers do seem to be the language that defines space and allows the forces to be characterized. I’d...

But I'm not sure space can be ionized.... I was not thinking that space is ionized; just that the area outside the nucleus of an atom (even devoid of electrons) may have a unique characteristic that has not been totally defined. Also, I was hypothesizing that it could be further elucidated whether ...

Well, there goes that delusion. It obviously doesn't add the gravity to my idea. Unless there is also a version of dark matter that adds to gravity but not to overall mass. Although light is affected by gravity curiously...

I'd have to admit that's true. My understanding of the short-lived particles is that they can be created in a vacuum. But doesn't space exist even in a vacuum? I think of space as the area between points or groups of matter. That light travels through vacuum faster than other matter only fuels my de...

Space seems to be the one intangible aspect of our physical experience we have trouble understanding. Quantum theory (the little I understand) depicts it to contain short-lived particles. Since we haven’t found dark matter, as far as I know, I frequently am curious if it is part of the emptiness als...

I might be up for Chevy Chase in one more movie – “Europa Vacation”

The diagram of the complex features makes me think of the planets that may have surrounded the sun. The planets (if they existed) would have all had angular momentum on their various orbital planes. If the sun had planets such as gas giants or rocky bodies could their remnants have contributed to th...

... A sunspot so large it was visible to the naked eye ... . I wouldn't encourage people to try to see sunspots with their naked eyes. Even when the Sun is low to the horizon and the visible light is significantly attenuated, there's still a lot of dangerous infrared radiation. It would be safer to...

Lots of information at this site.

I know I should never have started this – I can’t get that tune out of my head!! Well, at least I came up with another verse. Three Blind ‘lites, Three Blind ‘lites. See how they roam, See how they roam They all sent data to those at home To tell us a little of what we don’t know Too bad they end up...

I was comparing M7 to M45 (The Pleiades Star Cluster) similar appearance. http://apod.nasa.gov/apod/ap120903.html Short-timers on the cosmic scale, it’s odd that they won’t be around for long either. Talk about fast and furious. Being from similar origins, the large number of open clusters must repr...

That calls for some more satel’lite humor… Three Blind ‘lites. Three Blind ‘lites. Set them adrift. Set them adrift. They fall according to gravity laws At a rate we adjust for relative flaws You ever foresee such a flight in you life? As Three Blind ‘lites . Well, maybe no one called for it – Too l...

Do I detect the dust tail deviating from the ion trail in this photo? Or is that a "pigment" of my imagination... It looks as though the dust trail may be curving a bit "upward" in the photo. How long after rounding the sun would it normally take to see separation between those a...

I see they are still spending good money on the ISS. Has it ever been useful? Has it ever contributed anything to science? At the least, I think of our endeavors at the ISS as an investment? Are they the best investments we could make? Time will tell. Assessing the decision not to make the investme...

I enjoy the fictionalized APODs and would like to see more of them. Especially as depicted from other planetary systems and their realms to picture different landscapes as we may one day encounter. This one reminds me of some time in the distant past. It’s a bit foggy but there was definitely math i...

Why, Ann... that's just incredible :!: :lol2: I agree with Beyond. I think what I see as a "Celestial Dolphin surfacing from a Sea of Stars" might also agree… Dolphin.jpg …but I have little chance understanding fish-talk and your knowledge of the beauty of color. It’s great to know some d...

Those skies are incredibly dark! I can even see Barnard's Loop and Sh2-264!!! :D P.S. Yay tomorrow's APOD is RCW 58 ! Don’t be so sure. Those APOD people are tricky. Lots of bubbles out there It’s liable to be a GRB - GRB.jpg Or a BBB ?? (Big Bang Bubble) - BBB.jpg Monseigneur Georges Lemaître as a...

When we send another probe to Titan I would hope it included some way to explore under the surface of the ethane/methane lakes.

Looks to me like the Man in the Moon and the Lady in the Moon should get a room.

That may lead to a bad end for the rabbit. The Rabbit in the Moon in mean. The Jade version will do fine.

Nice. Helps to find your car, too.

Especially if the other guy has his high beams on driving up the hill you're coming down
