SCOTTISH legend has it that Robert the Bruce once took shelter in a cave, where he noticed a spider repeatedly trying, and failing, to build a web. The struggle against online piracy is beginning to feel the same way.

We don't have any trouble coping with three dimensions – or four at a pinch.
The universe is commonly defined as the totality of everything that exists , [ 1 ] including all matter and energy , the planets , stars , galaxies , and the contents of intergalactic space . [ 2 ] [ 3 ] Definitions and usage vary and similar terms include the cosmos , the world and nature .
Universe
A black hole is a region of spacetime from which nothing, not even light , can escape. [ 1 ] The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole. Around a black hole there is a mathematically defined surface called an event horizon that marks the point of no return.

Observable Universe
Visualization of the 93 billion light year – or 28 billion parsec – three-dimensional observable universe.
Galaxy
A galaxy is a massive, gravitationally bound system that consists of stars and stellar remnants , an interstellar medium of gas and dust , and an important but poorly understood component tentatively dubbed dark matter . [ 1 ] [ 2 ] The word galaxy is derived from the Greek galaxias ( γαλαξίας ), literally "milky", a reference to the Milky Way galaxy.
Nebula
The Triangulum Emission Garren Nebula NGC 604 A nebula (from Latin : "cloud"; [ 1 ] pl. nebulae or nebulæ , with ligature or nebulas ) is an interstellar cloud of dust , hydrogen , helium and other ionized gases . Originally, nebula was a general name for any extended astronomical object , including galaxies beyond the Milky Way (some examples of the older usage survive; for example, the Andromeda Galaxy was referred to as the Andromeda Nebula before galaxies were discovered by Edwin Hubble ).
An example of a spiral galaxy, the Pinwheel Galaxy (also known as Messier 101 or NGC 5457) A spiral galaxy is a certain kind of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae [ 1 ] and, as such, forms part of the Hubble sequence .

Virgo
The Virgo Supercluster ( Virgo SC ) or Local Supercluster ( LSC or LS ) is the irregular supercluster that contains the Virgo Cluster in addition to the Local Group , which in turn contains the Milky Way and Andromeda galaxies.
A supernova (abbreviated SN, plural SNe after supernovae) is a stellar explosion that is more energetic than a nova .

Imagine that you have a big box of sand in which you bury a tiny model of a footstool. A few seconds later, you reach into the box and pull out a full-size footstool: The sand has assembled itself into a large-scale ...
