Which term is generally used to designate theories opposed to the big bang theory?
a) singularity
b) little bang
c) steady-state
d) micro-origin

My teacher has used D)mirco-origin to opposed the Big Bang Theory but also singularity is what i heard, i hope this can help:)

Explanation:

C) Steady state

Explanation:

steady state opposed the Big Bang theory. It maintained that there is continuous creation of matter to form new stars and galaxies throughout the universe at the same rate that old ones become unnoticed. This is attributed to increasing distance and velocity of recession. Also, the expansion of the universe has been created at a constant rate throughout an infinite time and is still being created at the same rate today.

gravity causes stares to cluster i think so

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
