Big Bang Theory

What does Hubble's Law state?

• The universe is always moving

• Galaxies are attracted to each other

• Galaxies are always moving away from each other

• The universe expands to one point

Answer explanation

galaxies are constantly moving away from each other. The farther a galaxy is from us, the faster it is moving away.

What do scientists use to further our knowledge of space?

• Hubble Space Telescope

• Spitzer Space Telescope

• Chandra

• Hershel Space Observatory

Answer explanation

The Hubble Space Telescope allows us to develop more of our knowledge about space.

Why can't we use regular telescopes?

• The stars are too far away

• The moon's glare distorts the image

• The atmosphere distorts the image

• The sun blocks the stars

Answer explanation

Because of the thickness of the atmosphere, it distorts the image so we can not use them to study space

How did the big bang start?

• There was an explosion

• Light beams formed stars

• In a single area in a single moment

• The sun created solar glares which caused stars to form

Answer explanation

The big bang started in a single zone and took place over a single moment

What do we call the answer to the previous answer?

• Continuity

• Evolution

• Duality

• Singularity

Answer explanation

The name of the area taking place over a single moment is called singularity.

What formed the universes structures

• Gravity

• Momentum

• Acceleration

• Oscillation

Answer explanation

Although we know it in a different way, gravity is the force that pulls particles together. For us, it's the force that keeps us on the ground. In this case, it's what formed the universes structures.

Which of these is NOT a misconception

• The Big Bang was an explosion

• The universe is infinitely expanding

• There is a centre of the big bang

• The whole universe was formed in a single point

Answer explanation

The big bang was not caused by an explosion; there was not a centre of the big bang, only the singularity; the singularity was too hot to have particles exist so the universe was formed later on. The universe is indeed expanding infinitely

Who was the main scientist to discover the big bang?

• Albert Einstein

• Edwin Hubble

• Stephen Hawking

• Isaac Newton

Answer explanation

Edwin Hubble discovered this in 1929, and his discovery was the start to us getting closer to understanding the universe.
