about 13.8 billion years ago
According to astronomical research, the birth of the universe is estimated to have occurred about 13.8 billion years ago due to the Big Bang. By studying various evidence that indicates the universe’s early expansion—such as the cosmic background radiation and the light from distant galaxies—this timescale has been determined.

What happens if you release water inside a spaceship?
- flowing in a straight line
- to disperse in a mist-like form
- become spherical
See the answer
become spherical
In a spacecraft, a microgravity environment occurs, so water is not pulled down by gravity and becomes spherical due to surface tension. These spheres float, and as long as that condition is maintained, they retain their shape.
What is the phenomenon called that occurs when the universe contracts to a single point?
- Big Bang
- Big Crunch
- Big Freeze
See the answer
Big Crunch
The phenomenon in which the universe collapses back into a single point is called the “Big Crunch.” This theory holds that gravity will eventually reverse the expansion of the universe, causing everything to return to a single point. It is a phenomenon that would occur if the effect of gravity becomes stronger than dark energy, bringing the accelerated expansion to an end.
How many layers make up the insulation of a spacesuit?
- 8-layer
- 14 layers
- 20 layers
See the answer
14 layers
The insulation used in spacesuits is composed of as many as fourteen different layers of materials. These layers block heat and play a crucial role in protecting astronauts from the harsh conditions of space. Each layer has a specific function, and together they enable the spacesuit to perform at its best.
What month and day is Space Day established by JAXA?
- June 3
- September 12
- December 24
See the answer
September 12
It was established in 1992 by the National Space Development Agency of Japan (NASDA), now known as JAXA. By designating this day as “Space Day,” the goal is to deepen understanding of space and to increase interest and engagement in space development. September 12 is the day when Mamoru Mohri, the first Japanese astronaut, first went into space.
