Re: 5 planets detected orbiting Tau Ceti

A surface implies a sudden phase transition. Saturn likely lacks one.

:lol: I assume your question was meant in jest. :P
That partly alludes to my point though: We don't know the Tau Cet planets have surfaces (because we don't know their bulk composition).

Re: 5 planets detected orbiting Tau Ceti

i spoke about rocky planets and not gas giants (like you).... a "hypothetical" rocky planet four times heavier than the Earth should have a stronger gravity. Correct. My point, given that no assumptions of the planet's composition was stated, was that the planet could be one of those low-...

Re: Cool NASA

...And the fact that even NASA is doing it is all the more infuriating. I agree with most of what you wrote, but are you sure it's NASA doing this? I doubt NASA has funded this project. I can imagine something like this being done by a few employees at NASA on their own time and money, but to sugge...

Re: 5 planets detected orbiting Tau Ceti

But i think that 4.3 times the terrestrial mass is too heavy for chemical reactions for life is done because gravity would be too high ... no ? Why? There's a ~100 Earth-mass planet in our solar system with less surface gravity than Earth. Clearly the planet's mass can't be the only deciding factor...

Re: Totally Off The Wall.

1. I heard doppler used in Astromony? How is it used? Yes. The Doppler shift of absorption or emission lines in the spectrum of a body can tell you about the body's velocity. See this link . 2. Can it be used to determine the speed of the astral body? Partially. The velocity of an object toward or ...

Re: Star Trek Add-On and Models

We've had in the past an issue with a couple forum members who are no longer with us. They flooded the forum with hundreds of images of low-quality, unimaginative Star Trek models. It was so bad that it probably qualified as spam. To pour salt in the wound, they would register multiple accounts to a...

Re: Is a black hole a perfect sphere?

If a singularity is often referred as "point", it is not extended (points have no parts); there is no geometrical place of the points equidistant from another central point to get a circle and in which its diameter can rotate about itself to produce a (perfect) sphere. Sure that makes sen...

Re: Is a black hole a perfect sphere?

Very interesting! Can you give us an idea of what the orbital radii of these orbits would be? (like in units of the event horizon radius for example).

Re: Is a black hole a perfect sphere?

Aside from the jets expelling radiation, how could a black hole NOT be a sphere? I think he's talking about the singularity itself. Neutron stars have small mm-scale topographic variations preventing them from being perfect spheres. Do black hole singularities have perfectly spherical shapes? This,...

F-type stars do indeed have more rapid rotation than G-type stars.

Re: Do you really want that??

Sure, every once in a great while one of the hundreds of images you post looks nice, but the overwhelming majority are very lacking in originality and creativity. The signal to noise is obscenely low, that's the complaint (not to mention the behaviour issues).

Yeah... it may be time to consider the possibility that our Celestia community is moribund and the recent infection is a symptom of rigor mortis.
