Space is an immense and mysterious realm. Even with the incredible advances in technology that have allowed us to explore the outer reaches of our universe, the mysteries of space remain largely unsolved.
The true false quiz can help you to understand some of the most fascinating facts about space and its mysteries. The following five facts are just a sampling of what you can learn by taking this quiz.
In this article, we’ll take a look at 5 of the most intriguing things you didn’t know about space.
The Universe is Expanding
One of the most extraordinary facts about space is that it is expanding. This means that the distance between galaxies is increasing over time. This is due to a phenomenon known as the Hubble expansion, which is named after the famed astronomer Edwin Hubble who first discovered it in 1929.

The expansion of the universe is thought to be the result of a mysterious force known as dark energy, which is believed to be pushing galaxies apart. This has been confirmed by the latest observations of the cosmic microwave background, which is evidence of a period of rapid expansion in the early universe.
The Dark Side of the Moon
Another interesting fact about space is that the moon has a “dark side”. While half of the moon is illuminated by the Sun at any given time, the other half is in darkness. This means that the “dark side” of the moon is constantly in shadow and is never visible from the Earth.
This has led to speculation about what might be hidden on the dark side of the moon. Some theories suggest that the dark side is home to a variety of strange and mysterious phenomena, such as alien civilizations or secret military bases. Unfortunately, these theories remain unconfirmed and the dark side of the moon remains an enigma.
Asteroids Are Everywhere
Asteroids are small, rocky objects that orbit the Sun. They can range in size from a few meters to hundreds of kilometers in diameter. While most asteroids are located in the asteroid belt between Mars and Jupiter, there are actually millions of them scattered throughout the solar system.
The closest asteroid to Earth is a small, rocky body known as 1620 Geographic. This asteroid passes by Earth every year and is visible to the naked eye. There are also several other asteroids that have been observed to pass close to our planet, though none of them poses a threat to us.
Gravity is Everywhere
One of the most fascinating facts about space is that gravity exists everywhere. Even in the depths of intergalactic space, where there is seemingly nothing, gravity is still present. This is due to the fact that gravity is a force that is exerted by all objects with mass, regardless of how small or large they may be.
This means that even the smallest particles of matter, such as electrons and protons, exert a gravitational force on each other. As such, gravity is a ubiquitous force in the universe and is responsible for the movement of stars, planets and galaxies.
The Milky Way is Home to Billions of Stars
The Milky Way is the name given to the galaxy in which our Solar System is located. It is an immense collection of stars, gas and dust, and is estimated to contain up to 400 billion stars.
The Milky Way is thought to be about 13.6 billion years old and is believed to have formed shortly after the Big Bang. It is also home to our Solar System, which is made up of 8 planets, numerous dwarf planets and millions of asteroids, comets and other objects.
The universe is an infinite and mysterious realm, and we are only just beginning to scratch the surface of its secrets. The 5 facts mentioned in this article are only the tip of the iceberg when it comes to the wonders of space. As we continue to explore and observe the cosmos, no doubt more incredible discoveries will be made.
