In this article, we will discuss the Best 25 Frequently Asked Questions About Space and Black Holes that people ask.
1. What is space in short answer?
- Space is the vast, seemingly infinite expanse that exists beyond Earth's atmosphere. It's where celestial objects like stars, planets, and galaxies are found.
2.What are 5 facts about space?
- Space is completely silent because it's a vacuum with no air to carry sound.
- The Sun is a star at the center of our solar system.
- Space is incredibly cold, with temperatures reaching hundreds of degrees below freezing.
- The Hubble Space Telescope has provided stunning images of distant galaxies.
- Space travel is challenging due to the absence of air and extreme conditions.
3. Who created space?
- Space is not created by any individual or entity; it's a fundamental part of the universe that has existed since the Big Bang, the theorized origin of the cosmos.
4. Who started space in India?
- Vikram Sarabhai is often regarded as the "father of the Indian space program." He played a crucial role in establishing the Indian Space Research Organisation (ISRO) in 1969.
5. Why is space silent?
- Space is silent because it's a vacuum devoid of air molecules. Sound requires a medium, like air or water, to travel through, and in space, there's no medium to transmit sound waves.
6. What is space called?
- Space is often referred to as the "cosmos," "the universe," or simply "outer space."

9. How old is space today?
- Space, as we understand it in the context of the universe, is approximately 13.8 billion years old. This age is estimated based on the age of the universe itself, which was determined through cosmological observations.
10. How many days live in space?
- The length of time a person can live in space varies. Astronauts typically spend several months on the International Space Station (ISS), but longer missions, like those to the Moon or Mars, would last significantly longer.
11. Who is the father of space in India?
- Dr. Vikram Sarabhai is often referred to as the "father of the Indian space program" for his pivotal role in establishing and nurturing India's space agency, ISRO.
12. What are the 3 types of universe?
- There are three main cosmological models for the universe:
- Closed Universe: Finite and curved, where space eventually curves back on itself.
- Open Universe: Infinite and negatively curved, with space expanding forever.
- Flat Universe: Infinite and flat, with a balanced expansion rate.
