I WONDER - Is The Universe Flat?

The video explains that the universe expands in all directions without curving, making it flat. Unlike the Earth, which is round as confirmed by space exploration, the universe has zero curvature, meaning it is neither positively nor negatively curved, resulting in a flat geometry.

In which direction does the universe expand?

• In all directions

• Only upwards

• Only downwards

• In a circular path

What was the historical belief about the shape of the Earth?

• It was always known to be round

• It was believed to be flat

• It was considered to be a cube

• It was thought to be triangular

How was the round shape of the Earth confirmed?

• Through ancient maps

• By measuring shadows

• Via space exploration

• By observing the horizon

What type of curvature does the universe have?

• Positive curvature

• Infinite curvature

• Negative curvature

• Zero curvature

What does zero curvature imply about the universe's shape?

• It is conical

• It is cylindrical

• It is spherical

• It is flat
