We've all heard that the calender ends in december of 2012. What happens after that is subjective. Last night I heard another thing that stated that at that time the earth, our sun and the center of our galaxy will be in alighnment on the big day which may cause a magnetic polar shift on earth. Is it scientifically proven that the earth, sun and galaxy will be alighed on that day? I'm sure we can accuratly predict the positions so it should be easy to acertain if this is true or not.

Studying the Universe at University is quite fascanating, you realise that the Milky Way is so huge that we take up just 8% of it and only know 13% of it! There is another 87% of the Milky Way that mankind has never seen nor' expearianced, so if Planet Earth could be in the Milky Way, could there be another planet with life, like receantly they found Eris (EARTH LIKE with Liquid Water), and heat camera's have detected millions of suns in our galaxy so could there be other planets in our Galaxy with Life?? (I personally believe there is, but what do you think?)

I found out that using the Universal Parallax, you can calculate the distances to other Universal Objects, such as Stars and Galaxies, calculation based on luminance,size and the escape velocity from an object going away from another object!
But, stars have different luminosity, the one star can be yellow brightness +10, while the other star is brightness +5. Also they are variable in colour, from yellow, red and blue, etc...
They also have different sizes, like the Sun is 1 and the i.e. Antares is +- 300!
The speed of an object such as a Star is influenced by i.e. another star. So the parallax speed varies from one to another!

So, my guess is that the Universal Parallax is not that all accurate, taking the above factors into consideration!

In the Universe there are variable speeds, various sizes and luminosities!

So, I believe we don't know the acual distances, but using the Parallax is more theoretical

I've heard there wasn't really a "discovery date" for Stonehenge because it's always been around, but wasn't there a time when scientists came across it and said, "Hmm, this requires further investigation..." right? When was that? And if I were to say the "discovery date" is in the last 250 years, would I be right?

1. A mountain is 10,000 feet high. When you hold your arm straight out, three fingers cover the mountain to your view. How far away are you from the mountain?

2. A new planet is discovered orbiting the sun. It is 30 AU (astronomical unit) away. How many years does it take to orbit the sun?

3. The Ulysses space probe was sent in orbit around the sun to study it. If it takes 0.25 years to orbit, how far away from the sun is it?

4 What maximum angle could it make to your eye at sunset?

5. A comet takes 100 years to orbit the sun (a) Calculate its average distance R from the sun. (b) The comet gets as clode as 2 AU from the sun. How far away does it get?

6. A planet is 2 AU from a star and takes 2 years to orbit it (a) Find K for this star. (b) Is this star more massive or less massive than our sun? choose one

** it would be great if you could provide work so i can understand it much better. Thanks!!!

If balck holes are infinitely dense and the big bang erupted from a mass infinitely dense could that not mean that a black whole could possible erupt in much the same way
