Starship Asterisk*

The weirdest thing to me, is I can't put my finger quite on what is so stunning about it. Sure the technical challenge is awesome, but no more so than many of the other pictures we've seen. There's just something about it that caused me to stop and say "whoa" the instant the picture loade...

Agreed!

That photo is quite stunning, invigorating as well.
It makes me want to go discover something.

If you were traveling to a star system at the speed of light in the same direction that the universe is moving and returned at the same speed; would the trip there be longer than the return trip, or would the travel time remain the same? Why? :? Orin If your travel velocities are equal (relative to...

Ok, I'd like to start over if I may. I asked if the alternative theory has been considered . That questio has not been answered. I can't say, on a factual basis, how much that alternate theory has been considered by scientists. I wasn't able to find any published scientific papers on the matter. I c...

Confused, I don't think Astro was attaching you in any way, or even being very critical. You asked, he answered. Please don't take it personally or try to be so protective, it takes away from the intended manner of this forum. Has anyone suggested the possibility that galaxies are developed from bla...

Your math is correct, and although the idea and thought process is simple, I think the error lies in resolution. First off, I thought NGC 5005 was 5.8' x 2.8'. This arc angle is probably measured by a much more finer detail image, therefore making the one we see not as accurate. I.e, blur/glow can b...

I would imagine that first, because they cast a shadow it would be comparatively as dark as an eclipse. The rings may be quite thin when seen edge on but they cover an expanse that is nearly as deep (Inner most ring to outer most ring) as the diameter of Saturn Yes, also the sun only looks one tent...

I was thinking along the same path while looking at that picture.. It would be a full eclipse, but there would definitely be an erie view of the sun poking through.. If you were 'standing' in the right spot you could almost remain eclipsed from morning till night.. That would make for some interesti...

interesting...

Only if we could 'dissect' a photon. They must have mass.
Or at the very least, invoke a gravity arc.

It is layered sand of various colors and textures deposited from sand storms of different magnitude and direction then eroding back to reveal the geological differences in the sand carried from storm to storm. He says so matter of factly.. I think that is a quite possible theory, but one would expe...

http://antwrp.gsfc.nasa.gov/apod/ap061004.html This comet is hyperbolic. Once it leaves the solar system it will never return as it will go into interstellar space. I'm thinking it is not an Oort cloud comet; and not from our solar system. Probably a vagabond drifting through space? :roll: Orin It ...

The reflected light can also be blue shifted, dependent on the direction of the reflective object. The change in the wavelength = the + or - speed of the object Hmm, A light booster eh. So if a photon hits say a mirror traveling .5C towards the photon, the photon would end up with a velocity 1.5C i...

Did the site go down? Or was it clean up time...

I couldn't get on for a good day +

Is time independant to an event and can it influence the time of another event? Is anything independent? It seems motion/energy is the cause of time. But does this imply time is an actual "container" for events to pass thru? Perhaps time is a required reaction of motion/energy. Such as a ...

Hi Doum Yes the photon does lose energy, it is essentially redshifted so its wavelength increases. I did a little bit of research into solar sails in my undergrad days, the important thing is that for maximum propulsion the sail has to be reflective. Naively you would assume it is better for the sa...

Here ya go

Welcome Nereid! Link away, sounds interesting.

Where did you get them?

Thanks for the links and explanation Astro. So, if Harry's aformentioned H2 (redshift) theory were correct, we would expect to see similarly evolved galaxies at every redshift, or at the very least, a uniform distribution of evolution at every redshift. This is obviously not what is observed. Ok, th...

Ellipse with exactly .01 eccentricity.

Note: My image hosting site might have skewed it.

Not to reinforce possibly derogatory comments but.. HAHAHAHAA that made me crack up.

Read this and let us know what you think.

I imagine that it would be the brighter of the two dots. 1) Because it's relative brightness is comparative to that of Saturn's from an earth orbit. 2) It's location with reference to where the sun must be if Cassini is in Saturn's shadow. 3) I think the author would have noted otherwise if Earth wa...

Ha! didn't even think of that.. Maybe he's Duke the 3rd.


Welcome.

I skimmed this and it seems to make sense to me. Only, why would so many researchers overlook something like this?
There is most certainly more to the story, and I'm interested in hearing what others have to say on the topic..
