1) Message boards : Science (non-SETI) : Question about our solar system's rotational axis (Message 1616788)
Posted 56 seconds ago by Profile Bob DeWoody
My question was related to this thought. If most star/planet systems are oriented in generally the same plane as the spin of the galaxy then we should be able to see/detect a lot of planets as they circle their star(s). That is assuming any given star is observed long enough for the effect of a planet crossing it's star to repeat itself. Someone would have to watch our sun for a long time, almost 12 years, to detect Jupiter completing an orbit. That, for us, is a long time to watch just one star.

So far the planet hunters have been finding stars with planets that complete an orbit in a few days to a few weeks which in my mind makes them unlikely candidates for finding life or being suitable for colonization. So how will they detect stars with planets that have orbital periods similar to ours.

My biggest question. Where did the 1st officer end up when the little girl zapped him and the guy from the outside?

I would like to see a compilation of the discoveries that were made and science that was achieved during it's tenure at Venus. Most all of the stuff that is available at the ESA website is just little news bytes released over the last eight years.

It will be a real bummer if they don't do some follow up episodes. Too many unresolved issues if this was it.

Bob -- This is a fast, and incomplete reply. The Earth's axis is skewed,
and it wobbles. This is nothing new, to you. As for the solar system's
axis, w/respect to the plane of the Milky Way -- I don't know. Will try
Googling it.

There is a good book on a planet's axis, and more, on a planet without a
sufficiently-large moon to provide relative stability, "What if the Earth
Had Two Moons?", by Nicholas Carr.

I knew the earth was tilted and wobbles but uncertain about the entire solar system.

One of our more brilliant members should know the answer to this. Is our solar system's rotational axis aligned with that of the whole galaxy? Or is it skewed at some angle or does it wobble?

it seems to me that a sphere would always appear as a disc and that crossing it at any angle would be discernible. They also use the wobble effect of a planet on it's star to imply a planet's existence.

An object orbiting a sphere when viewed from somewhere outside the system will only cross in front of the sphere when the orbital plane is nearly edge on to the observer. When viewed from the perpendicular the object will remain nearly the same distance from the center depending on how circular the orbit is.

The wobble method can determine whether a star has companions but not much else.

It could easily be compressed into a single 3 hr movie without loss of meaningful content. But that is true of most serial movies.

Maybe the next three episodes won't leave us so much in the dark.

There are no more episodes.

According to IMDB there are three more episodes in the can.

After it's initial encounter with Venus news regarding any discoveries it made have not made the headlines. I think I will read up on what it discovered.

As I understand the method, only planets that transit across the face of a star can be detected. Meaning their orbital plane must be near to edge on relative to earth. Unless there is some bias toward this orientation we may be missing thousands of planetary systems whose orbital plane is canted at angles greater than a few degrees up to 90 degrees

We are small and insignificant even if all there is is the Milky Way galaxy. In the bigger scheme of things we are infinitesimal. I really wonder how much of the big picture we are missing or are completely wrong about.

Well, as I suspected the story is a long way from it's conclusion. Series to follow as long as the ratings were high enough. It is a very engrossing plot line, one of the best in a long time from the SyFy channel.

With no outside force applied, over time, a system or object will decay due to entropy. Therefore the argument that our (uni)verse will expand and decay until the last particle pops out of existence, in a few trillion years.

So, just how do you deal with organizations whose goal is anarchy, or in other words the total breakdown of law and order? or at least non muslim non religious law and order.

If the torture of just one terrorist prevented just one event like what just happened from occurring was it justified? Does the means justify the end when the stakes are so high and failure opens the way for the slaughter of innocent women and children?

They are airing all three episodes tonight. Depending on the outcome I wouldn't be surprised if it turned into a weekly series. And Tricia Helfer is just as hot in this one as she was in Battlestar Galactica.

After watching the second episode I'll be back tomorrow to watch the finish. It's good to see they were very adult about needing adult diversions. One thing has surprised me so far and that is the lack of a recreational drug sub culture on board. So far there's been no mention of how the "down below" work force was recruited. There is a lot of back story that is vague or missing but maybe that is something left for future installments.

Part 1 is only an hour and 6 minutes without ads.

That is why I referred to it as a movie in parts vs. a mini series.

Confirms my belief that the terrorists at guantanamo were too well treated.

Only if the life being mentioned is intelligent. If we are just talking about microbes this is the right place.
