GIZMOS STUDENT EXPLORATION BIG BANG
THEORY HUBBLE’S LAW COMPREHENSIVE TEST
PAPER 2026 COMPLETE QUESTIONS AND
ANSWERS EXPERT VERIFIED GRADED A+
◉ Red Shift. Answer: A shift toward longer wavelengths of the
spectrum. The shift is caused by the object, which is emitting the
waves, moving away from the earth. All stars and galaxies are
moving away from earth--Evidence of The Big Bang Theory
(Hubble's Law)
◉ Cosmic Background Radiation. Answer: Evidence of the Big Bang
Theory. Left over heat energy from the Big Bang is observable at all
points in space. The energy started as light but has shifted to
microwaves and radio waves due to the continual expansion of the
universe.
◉ Age of Universe. Answer: ~13.7 billion years old
◉ First two elements created. Answer: Evidence of the Big Bang
Theory. Hydrogen and Helium because they are the simplest, lightest
elements with the least number of protons, neutrons, electrons.
, ◉ Big Bang. Answer: All matter and space were created from a single
point of pure energy in an instant.
◉ Composition of Early Universe. Answer: 75% Hydrogen and 25%
Helium
Evidence for the Big Bang because current measurements match
with the predicted composition of the universe.
◉ How did atoms form?. Answer: Universe had to cool, electrons
could then slow down and join nuclei (protons and neutrons) to
form a complete atom/element. First elements were hydrogen and
helium (simplest).
◉ Galaxy. Answer: Groups of billions of stars and the planets that
orbit them (the stars)
◉ Universe. Answer: All existing matter, energy, and space
◉ Dark Matter. Answer: Unseen and unidentified matter that is
evident by its gravitational pull on stars in the galaxies.
◉ Dark Energy. Answer: A mysterious force that appears to be
causing the expansion of the universe to accelerate
