with the
universe's
mass on the largest scales: as these particles careen through the
universe at near light - speed, they interact

mass of the
universe accelerated to many times the speed of light
in a fraction of a second and should have set the entire cosmos ringing

in the
universe attract each other
with a force that is proportional to the
mass of the objects and that diminishes
with their distance from each other.

in the
universe and their

«This ultraluminous quasar
with its supermassive black hole provides a unique laboratory to the study of the
mass assembly and galaxy formation around the most massive black holes

Dark matter makes up most of the
mass in the
universe but shuns contact
with ordinary matter.
But
in a high - density
universe, small fluctuations will readily form galaxies, because there is more
mass to work
with.

with dark matter but can not describe the
universe simply as the product of a tweaked Einsteinian gravity acting on the
mass we can see.

Therefore, those monsters,
with a total
mass 50 times that of the Sun, formed
in an extremely dense compact
universe — exactly as postulated by the stretching explanation, but something a big bang would not produce.
