Explanation:
How did we get here?
We know that we live on a planet orbiting a star orbiting a galaxy, but how did all
of this form?
To understand details better, astrophysicists upgraded the famous
Illustris
Simulation into
IllustrisTNG --
now the most sophisticated computer model of
how galaxies evolved in our universe.
Specifically,
this featured video
tracks magnetic fields from the early universe
(redshift 5) until today
(redshift 0).
Here blue represents relatively weak
magnetic fields, while white depicts strong.
These B fields
are closely matched with
galaxies and
galaxy clusters.
As the simulation begins, a virtual camera circles the virtual
IllustrisTNG universe
showing a young region -- 30-million
light years across -- to be quite filamentary.
Gravity causes galaxies to form and merge as the universe expands and evolves.
At the end, the
simulated IllustrisTNG universe
is a
good statistical match to our present real universe,
although some interesting differences arise -- for example
a
discrepancy involving the power in
radio waves
emitted
by rapidly moving charged particles.
