Starship Asterisk*

The 'Hubble Tuning Fork' is a classification system, it doesn't actually have anything to do with galactic evolution.

http://antwrp.gsfc.nasa.gov/apod/ap090824.html Nice picture, but ... where's the astronomy? I've defended the choice of weather and atmospheric pictures before, even on flimsy grounds like "the air is what we look through to see the stars." But in this picture we're not even looking up to...

So did plant life and animal life both evolve from the same line of cellular life, or did conditions and predecessor organisms produce two separate lines? Is there any genetic correlation between plant DNA and animal DNA? Plants, animals, and fungi are all pretty closely related, as these things go...

Was it anything like the last picture on this person's blog entry?

My assumption is that the light was being scattered through different thicknesses of atmosphere, emphasizing different wavelengths. But even if that wasn't the case, this is easily one of the most amazing things I have ever seen. I've seen what I think you're describing up here in Ontario, Canada a...

Entanglement doesn't permit the transmission of information faster than light, so it wouldn't be any different than using a normal telescope, unfortunately. Have a read of this. : Quote if this experiment is done with entangled particles the results are quite different. When two members of an entan...

I harbor serious doubts that anyone manufactures double-glazed windows with panes that are aligned in optical-quality perfect parallel...

As we see them now, they're ten million years old, but the light that we see from them now left that galaxy 15 million years ago (since the galaxy is 15 million light-years away).

Loco wrote:...then why should the CMB be echoes of an explosion?

It isn't. The Big Bang theory doesn't describe an explosion in the first place.

I guess it's just a reference to Jupiter as the largest of the planets, and also that it's named for the Roman king of the gods.

Maybe this APoD will illustrate the illusory nature of the effect a bit better.

Sounds more like Asimov's "The Last Question" to me.

Please explain how this makes sense. Two objects are approximateley the same size. The compositions of the objects is similar. The hot one is ten times the mass of the small cool one. With gravity and the ideal gas law we have a problem. Bear in mind that, ignoring gravity and assuming both of thes...

How about "straw man argument" then?

I believe they're 'closed' in the sense that, beyond the horizon, spacetime is so warped that there are no possible paths that lead back out of the horizon. So it's more like a Roach Motel™ than a closed door.

Assuming you don't count the CMB as an event, of course. A gamma-ray burst at a whopping-huge z=8.1, or more than 80 Gpc.

I think you might've neglected to consider that Earth (or even the solar system) isn't the 'place of origin' for any of the material of which the Pioneer probe is constructed. Any hydrogen in its makeup has likely been around since the beginning, and the rest of the heavier elements would've been ma...

G'day Qev Qev said You cannot alter your measurement of the passage of time in your own frame of reference, period; the idea doesn't even make sense without a comparison to another frame. Relative motion will cause you to measure the time passing in other frames of reference differently, though. Ye...

Astronomers observe infalling gas colliding with the surface of compact objects like neutron stars, which considering the depth of the gravitational well is a rather energetic sort of event. They don't see this occurring with black hole candidates, which implies that there is no surface, ie. an even...

G'day from the land of ozzzzzz Apply the black box approach. What ever happens within the Gyr box cannnot effect time outside. You cannot alter time in one area and not effect time in another. You cannot alter your measurement of the passage of time in your own frame of reference, period; the idea ...

Hawking radiation has nothing to do with polar jets.

Earth hates it when you anthropomorphize her.
