What happens to matter and energy in the universe?
So in an expanding Universe, radiation loses energy due to its wavelength redshifting, but matter with kinetic energy loses that energy thanks to the expansion of the Universe, too!
What will happen at the end of the universe?
Trillions of years in the future, long after Earth is destroyed, the universe will drift apart until galaxy and star formation ceases. Slowly, stars will fizzle out, turning night skies black. All lingering matter will be gobbled up by black holes until there’s nothing left.
What Do scientist believe matter is made up of?
The familiar material of the universe, known as baryonic matter, is composed of protons, neutrons and electrons. Dark matter may be made of baryonic or non-baryonic matter. To hold the elements of the universe together, dark matter must make up approximately 80\% percent of the universe.
What do scientists believe the universe began as?
The Big Bang was the moment 13.8 billion years ago when the universe began as a tiny, dense, fireball that exploded. Most astronomers use the Big Bang theory to explain how the universe began.
What do scientists think is the most abundant form of matter in the universe?
But what about plasma? It’s the most abundant state of matter in the universe, but plasma can’t exist for long under normal terrestrial conditions. Out in space, exotic plasmas can occur inside white dwarfs, large planets like Jupiter, and the Sun and other large stars.
Do scientists know where the universe ends?
Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space. But nobody knows for sure.
Where did energy in the universe come from?
Initially, the universe was permeated only by energy. Some of this energy congealed into particles, which assembled into light atoms like hydrogen and helium. These atoms clumped first into galaxies, then stars, inside whose fiery furnaces all the other elements were forged.
