What choo talking bout Matt Rain?

You can't be in the same position just with respect to the sun. If there was nothing but the earth and sun, positioning is not possible. It has to be relative to something else, in this case the zodiac which is a band in the sky (18 degrees wide as I recall) with a group of constellations as background. All the objects in our solar system "live" within the zodiac from our visual perspective and that's how we measure spacial relativity. So the same constellations would be at zenith/nadir today as the day mcb was born.

Are you sure you want to argue with the former astrophysics student, son? We don't take kindly. :bat:

I will argue with the former astrophysics student. My point is that the Earth and Sun are infinitely closer in regards to their relative positions some 30 years later, than the Earth is with any other celestial body that is outside the solar system. Spinning galaxies and galaxy clusters, universe expansion and all that. While you can still point your telescope at the same tiny spot in the sky and see the same star 30 years later, it is a lot farther out today, in terms of absolute distance, using human-scale standards of omg-that's-pretty-fucking-far.

Nitpicking is all. It's Matty Rain's birthday, let's have some cake.

And if you're about to point out that stars that are visible to the naked eyed are all well within the boundaries of our own galaxy, which makes the influence of macro-spinning-and-expanding-phenomenons pretty damn negligible on those, well, you'd be right obviously. I was born and raised in the city, where there is no such thing as a star that is visible to the naked eye. :grin:

Hmmm, cake.
