What Was the Big Bang and Other Space Questions Answered! | SciShow Kids

The video explores the fascination with space, starting with how math is used in astronomy to measure distances of stars and planets. It explains the concept of parallax and how Earth's movement helps in these calculations. The video then delves into the Big Bang theory, describing the universe's expansion from a singular point. Finally, it discusses Venus's atmosphere, highlighting its differences from Earth's and the challenges it poses for exploration.

How do astronomers use math to determine the distance of stars from Earth?

• By measuring the brightness of the stars

• By observing the color of the stars

• By calculating the apparent jump of stars at different times of the year

• By counting the number of stars in a constellation

What role does Earth's movement play in measuring star distances?

• It helps in observing stars from different angles

• It changes the color of the stars

• It has no effect on star measurement

• It makes stars appear brighter

What is the Big Bang theory?

• A theory that explains the creation of galaxies

• A theory about the formation of black holes

• A theory that describes the universe's expansion from a tiny point

• A theory that suggests the universe is shrinking

Why do scientists believe the universe is expanding?

• Because galaxies are moving closer to us

• Because planets are changing colors

• Because galaxies are moving away from us

• Because stars are getting brighter

What is the main component of Venus's atmosphere?

• Oxygen

• Nitrogen

• Carbon dioxide

• Helium

Why is Venus's atmosphere considered dangerous for humans?

• It is very hot and heavy

• It is too thin

• It is filled with oxygen

• It is too cold

What happens to spacecraft sent to Venus?

• They last for a long time

• They get smushed due to the heavy atmosphere

• They float in the atmosphere

• They return to Earth safely
