The Fate of the Universe: Cosmic Endgame Scenarios

What long-term event will happen to the Sun according to the video?

• It will turn into a black hole

• It will expand and swallow Earth

• It will remain unchanged

• It will explode as a supernova

What role does Einstein's general relativity play in cosmological theories?

• It has been central to developing theories about the universe's fate

• It describes the quantum mechanics of particles

• It is fundamental in understanding time dilation

• It predicts the behavior of black holes

Which factor is NOT considered when theorizing about the end of the universe?

• The color of galaxies

• The motion of galaxies

• The structure of the universe

• The amount of dark matter and energy

What is the significance of dark matter and dark energy in understanding the universe's fate?

• They suggest the universe will shrink

• They play a crucial role in theoretical models of the universe's end

• They are irrelevant to the universe's expansion

• They indicate the universe will stop expanding

Which theory of the universe's end involves it expanding and cooling to a dead state?

• Big Slow

• Big Freeze

• Big Crunch

• Big Rip

What does the Big Freeze scenario imply about future cosmic activity?

• Increased star formation

• Ceasing of all interesting phenomena

• Galaxies will start moving closer

• Black holes will grow larger

What does the Big Rip scenario predict?

• The universe contracts

• Galaxies will stop moving

• The universe stops expanding

• Everything gets torn apart due to expansion

How does the Big Rip scenario affect galaxies?

• It stops the movement of galaxies

• It makes galaxies invisible

• It pulls galaxies apart

• It causes galaxies to merge

According to the Big Crunch theory, what triggers the universe to begin contraction?

• A decrease in the Higgs boson activity

• A stabilization of the Higgs field

• An increase in the universe's average density

• A decrease in dark energy

What does the Big Bounce theory suggest?

• The universe cycles between expansion and contraction

• The universe will expand indefinitely

• The universe will stop expanding and stay static

• The universe will eventually freeze completely
