2. _______ 1.) A matter that has gravity but does
not emit light.
_______ 2.) It is born out of clouds of gas and
dust in galaxies—the building block of galaxies.
_______ 3.) Where is the solar system located?
_______ 4.) A source of anti-gravity.
3. _______ 5.) This theory states that galaxies are
moving away from each other.
_______ 6-8.) The three (3) pieces of evidence
that withstood the tests for the expansion of the
universe.
_______ 9.) It is a residual radiation, or a faint
‘glow’, from the big bang 13.8 billion years ago.
4. _______ 10.) This theory postulates that 13.8
billion years ago, the universe expanded from a tiny,
dense, and hot mass to its present size and much
cooler state.
_______ 11.) This theory states that the universe
was expanding but still retained the core idea that
the universe always looks the same, and is therefore
unchanging in practice, and has no beginning or
end.
5. _______ 12.) What are the three (3) most
abundant elements in the universe?
_______ 13-15.) The three (3) scientists who
reformulated the Steady State Theory.
_______ 16.) This hypothesis about the origin of the
solar system says there is a rotating gaseous cloud
that cools and contracts in the middle to form the sun,
and the rest forms a disc that becomes the planets.
6. _______ 17.) His accretion theory proposed that
the sun passed through a dense interstellar cloud
and emerged with a dusty, gaseous envelope that
eventually became the planets.
_______ 18.) Who proposed sun-comet encounter
that sent matter to form planets?
7. _______ 19.) Who proposed sun-star encounter
that would have drawn from the sun matter that
would condense to planets?
_______ 20.) His capture theory is a variation of
James Jeans’ near-collision hypothesis. In this
scenario, the sun drags from a near protostar a
filament of material that becomes the planets.
