using nothing more than newton’s laws of gravitation, we astronomers can confidently predict that several billion years from now our home galaxy, the milky way, will merge with our neighbouring galaxy, andromeda. because the distances between the stars are so great compared to their sizes, few if any stars in either galaxy will actually collide.
any life on the worlds of that far off future should be safe, but they will be treated to an amazing billion-year-long lightshow.

Scale of the universe
Scroll to your hearts content from the Planck length to the diameter of the observable universe - click on any object and it will open an info box - I can’t imagine how much work must have gone into this.

Most people consider mushrooms to be the small, ugly cousins of the plant kingdom, but theirs is surprisingly beautiful and wonderful world waiting to be explored. These beautiful mushrooms, captured by enthusiastic nature photographers, are a far cry from the ones you find in the woods or your local grocery store.
Most mushrooms, as we know them, are actually just the reproductive structure of the fungus they belong to – their fungal networks expand far further underground, and some fungi don’t even sprout the sort of mushrooms that we’re used to seeing.
