Day 1 Big Bang Theory Exit Ticket

What was most likely to form after the Big Bang?

• planet

• comet

• star

• moon

Answer explanation

The universe began 14 billion years ago with the big bang. The big bang produced hydrogen and helium, but most of the heavier elements are created only by the thermonuclear fusion reactions in stars, so they would not have been present before the first stars had formed. Therefore, stars had to be made first.

Cosmic Microwave Background (CMB) provided evidence the universe was once hot and dense. How did this contribute to the big bang theory?

• it was the magnetic field that created and lead to the universe

• it shows reflected and thermal energy in the universe

• It shows energy trails that can be traced back to the creation of the universe.

• confirmed how matter expanded during the big bang

Answer explanation

The CMB shows cooling and the CMB shows the leftover heat from the big bang.

According to the big bang, which element formed first?

• oxygen

• helium

• nitrogen

• hydrogen

Answer explanation

Hydrogen and Helium make starts. Without stars forming first, we would not have other elements.

The Big Bang Theory suggests that our universe formed as the result of a huge explosion that sent all existing matter flying outward from a single point. The Big Bang Theory is supported by which of these observations?

• All matter in the universe is composed of the same atoms.

• All galaxies appear to be moving away from all other galaxies.

• All stars in the universe are approximately the same age.

• The universe is relatively the same temperature in all locations.

• The universe is staying the same.

• The universe is getting cooler and bigger.

What does it mean if a galaxy gives off light which has been shifted toward the red end of the electromagnetic spectrum?

• The galaxy is much older than Earth.

• The galaxy is moving away from Earth.

• The galaxy is very hot and has not cooled down yet.

• The remnants of an explosion are between the galaxy and Earth.

As part of The Big Bang Theory of the formation of the Universe, scientists believe that over time, the universe is continually changing in what characteristic?

• From more dense to less dense.

• From rotating to stationary.

• From cooler to hotter.

• From very large to very small.

Cosmic Microwave Background Radiation (CMBR) is the term used to describe the residual microwave radiation observed everywhere in the universe that seems to have no single source. The observation of CMBR is used as evidence of The Big Bang Theory because it is believed to be -

• The result of collisions between neighboring galaxies.

• Particles of dust that have absorbed radioactivity.

• Radiation left over from the rapid expansion of matter.

• Light energy emitted from the source of The Big Bang.
