we-are-star-stuff:

Dark nebulae composed of gas and dust provide the raw material for the star formation process. After becoming free of their birth shroud, the most massive stars, blue and hot, emit radiation causing the red glow of the hydrogen gas.

I’d like to share my classroom, where I’ll be teaching a summer camp called "Cosmic Curiosity" for the next two months.  It’s going to be awesome!
The universe is the mirror in which we can contemplate only what we have learned to know in ourselves.
I live on Earth at present, and I don’t know what I am. I know that I am not a category. I am not a thing – a noun. I seem to be a verb, an evolutionary process – an integral function of the universe.

urvogel asked: so with the cartesian space picture, is it implying that, because the cone of past and future light only become 'focused' (pointed) on the "present" moment, that past and future light becomes more dispersed? or am i overthinking it? i understand the concept that time as a dimension becomes relative to the viewer- and it goes without saying that light, the farther it goes out (or "farther into the future") becomes more dispersed across space and time. love your tumblr btw :)
The 3-dimensional shadow of a rotating 4-dimensional hypercube or “Tesseract”.
Because we are 3-dimensional beings, we cannot directly imagine 4-dimensional objects.  To perceive them, we must image their 3-dimensional ‘shadows’ by removing one dimension of space.  As a mental exercise, try to imagine the shape of a planetary orbit or a dividing cell in this Cartesian space.
ordinarywiseguy asked: that last image is wrong, you know?

I assume you’re speaking of this image, which shows the trailing orbits of the planets behind the sun.  The part which is incorrect is where it says we are “spiraling”.  A popular youtube video describes this as a “vortex”, which is also incorrect.  The animation has been thoughtfully debunked by Phil Plait of bad astronomy.  A more correct term would be ‘traveling in a helical path’.

I am disappointed that neither the original animation or the debunking describe what I consider to be a very important point; the orbit of any moon, planet, or star forms a helix, when you consider that the direction it is traveling is in a time dimension.
