Every galaxy has a

supermassive

black hole

anchoring its center

Mbh = millions to

billions of Suns

Gravity wins!

  • Galaxy continues to

  • make new stars.

  • Time scales are

  • lengthened by:

  • Recycling

  • Infall onto disk

  • Reduced SF rate


Cosmic genesis physical laws drive the formation of structure in the universe

Star formation continues

until the galaxy runs out of gas

(trillions of years from now)

The smallest, longest lived stars

last for tens of trillions of years

Our universe is young:

Only one tenth of one percent

of the Stelliferous Era has

taken place so far!
