Cosmologist
* Most cosmologist now agree on a theory of the creation and evolution of our solar system.
* Most cosmologists agree that the universe is evolving
  - believe that knowing which geometry is the most correct is important
* actually run computer simulations to track how matter collects into valleys.
  - loath to include a cosmological constant in their equations
* ask if the universe is 'open' or 'closed'.
* can hold almost any faith, or none.
* consider the cosmological constant the factor behind the accelerating force.
* continue to search for the missing mass, with both theory and observation.
* do it with large inflationary periods.
* generally agree that our universe is spatially finite.
* look at the universe as a whole
  - to the total amount of matter in the universe
* now have a full understanding of how galaxies form.
* often work with a given space-like slice of spacetime called the comoving coordinates.
* prefer another definition of 'universe' based on physics.
* think they've dated the moment of creation.
* usually assume that matter is spread uniformly across space.

Modern cosmologist
* continue to debate the ultimate fate of our universe.
* leave a niche in their models for an intelligent observer.

### animal | vertebrate | fish | bony fish:

Sturgeon
* also have the longest lifespan and have been known to live a century and a half.
* are a northern hemisphere fish
  - unique and valuable resource, both biologically and economically
  - also valuable for their roe which is sold as caviar
  - anadromous
  - big fish, so it takes a hefty rod and reel
  - bottom feeders, eating primarily insects and small crustaceans
  - cartilaginous, so there is No danger of choking on a bone
  - large, primative looking fish
  - much more primative than catfish
  - mysterious bottom dwellers and it is difficult to determine their numbers
  - no longer important commercially, however, because of their scarcity
  - one of the oldest living types of bony fish
  - primarily bottom feeders and eat just about any dead fish that they can find
  - prolific breeders
  - relatively slow growing fish
  - shark-like in form but are unique in having five rows of bony plates along the body
  - terminal carnivores
* are the largest fresh water fish on Earth
  - most common fish along the bottom, but there are lots of others to see
* can live as long as humans, although little is known about their life cycles
  - really get a fix on food, and if they're in that hole, they'll find the food
* deposit their large, sticky eggs on hard surfaces.
* have an elongated body and head and a sharklike upper lobe of the tail fin
  - unerring survival instinct
  - no bones or teeth
* is by far the most commercially valuable fish
  - considered an especially holy fish
  - protected under both United States law and international treaties
  - the fish of choice for premium caviar
* legendary figure in science fiction.
* like to stay in deep water.
* live only in the Northern Hemisphere.
* migrate up rivers to spawn.
* represent an important source of foreign capital for Azerbaijan.
* seem to jump mostly prior to an electrical storm.
+ Dabry's sturgeon: Ray-finned fish
  * Sturgeon are anadromous. This means they spawn in fresh water and migrate to salt water to mature.

### animal | vertebrate | fish | bony fish | sturgeon:

Atlantic sturgeon
* are an anadromous fish that can be found in ocean waters.
* continue to be a valued commercial fish, however.
* is sturgeon.
* make their way into the rivers in the late spring and up to early fall.
* mature very slowly.
