These activities are designed to be carried out by children working with a parent, guardian or other appropriate adult. the adult involved is fully responsible for ensuring that the activities are carried out safely. demonstrate how our universe is expanding with just a balloon and a pen. fun and easy astronomy experiment for kids. He said that a very long time ago, the universe started as just a single point. he said the universe stretched and expanded to get as big as it is now, and that it could keep on stretching. what an idea! the universe is a very big place, and it’s been around for a very long time. thinking about how it all started is hard to imagine.
The universe. the universe is everything we can touch, feel, sense, measure or detect. it includes living things, planets, stars, galaxies, dust clouds, light, and even time. before the birth of the universe, time, space and matter did not exist. the universe contains billions of galaxies, each containing millions or billions of stars. The observable universe is around 93 billion light years across. the universe is expanding. one of the interesting things about the universe is that it is currently expanding. it's growing larger and larger all the time. not only is it growing larger, but the edge of the universe is expanding at a faster and faster rate. Time, space and matter all began with the big bang. in a fraction of a second, the universe grew from smaller than a single atom to bigger than a galaxy. and it kept on growing at a fantastic rate. it is still expanding today. as the universe expanded and cooled, energy changed into particles of matter and antimatter. The universe has no centre and is constantly expanding (getting bigger) every second – making it impossible to reach the edge. 5. the earth is about 4.5 billion years old – but that’s only a third of the age of the universe – which is 13.5 billion years old! 6.

Dark energy is a repulsive force and makes up roughly 68% of energy in the known universe. scientists believe that the existence of dark energy and the amount of repulsion it displays compared with dark matter is what's causing our universe to not only expand, but also to expand faster and faster. hubble science: dark energy, a mysterious force. Some scientists think that dark energy is a fundamental, ever present background energy in space known as vacuum energy, which could be equal to the cosmological constant, a mathematical term in the equations of einstein's theory of general relativity. originally, the constant existed to counterbalance gravity, resulting in a static universe.
