How Big is the Universe?

The video explores the concept of the universe, emphasizing that it has no edge and is ever-expanding. It distinguishes between the observable universe and the entire universe, explaining that the observable universe is centered around the observer. The video clarifies misconceptions about the universe's expansion, stating that it is not expanding into something but rather stretching. The Big Bang is described not as an explosion but as a cosmological event where everything was evenly spaced. The possibility of an infinite universe is also discussed, with current data suggesting it might be infinite and expanding.

What is the observable universe compared to in the video?

• A sphere centered on the observer

• A pyramid with a peak

• A flat plane with edges

• A cube with corners

How is the universe described in terms of its density and expansion?

• Unevenly dense and shrinking

• Evenly dense and ever-expanding

• Dense at the center and expanding outward

• Sparse and contracting

What common misconception about the universe's expansion is addressed?

• That it is shrinking

• That it has a fixed size

• That it is stationary

• That it is expanding into something

How does the video describe the Big Bang?

• As a traditional explosion

• As a gradual process

• As a non-explosive event

• As a collapse

What does the video suggest about the universe's size?

• It is infinite and expanding

• It is infinite and contracting

• It is finite and shrinking

• It is finite and stationary
