can anyone tell me what space is, I know matter is energy and time is changes in the state of energy, so is space a static form of energy. I'd like someone to explain using simple terms if possible please.
Space refers to the vast, three-dimensional expanse that contains all matter and energy in the universe. It is often described as the absence of everything, but it actually contains various forms of radiation and particles.
Space is immeasurably vast and continuously expanding. The observable universe, which includes all the galaxies and matter we can detect, is estimated to be about 93 billion light-years in diameter.
In space, gravity still exists and is responsible for holding objects like planets, stars, and galaxies together. However, it is much weaker in space due to the large distances between objects.
Humans can survive in space with the help of specialized equipment and technology, such as spacesuits and spacecrafts. However, the lack of gravity and exposure to radiation can have negative effects on the human body.
Objects in space move according to Newton's laws of motion, which state that an object will remain in motion or at rest unless acted upon by an external force. In the vacuum of space, there is no air resistance, so objects can continue moving in a straight line unless acted upon by gravity or other forces.
