What is the universe made of?
Astronomers face an embarrassing conundrum: they don’t know what 95% of the universe is made of. Atoms, which form everything we see around us, only account for a measly 5%. Over the past 80 years it has become clear that the substantial remainder is comprised of two shadowy entities – dark matter and dark energy. The former, first discovered in 1933, acts as an invisible glue, binding galaxies and galaxy clusters together. Unveiled in 1998, the latter is pushing the universe’s expansion to ever greater speeds. Astronomers are closing in on the true identities of these unseen interlopers.

✏️Universe Made Of

\red{⊱─━━━━━━━━⊱༻●༺⊰━━━━━━━━─⊰} \:⊱─━━━━━━━━⊱༻●༺⊰━━━━━━━━─⊰

The Universe is thought to consist of three types of substance: normal matter, ‘dark matter’ and ‘dark energy’. Normal matter consists of the atoms that make up stars, planets, human beings and every other visible object in the Universe.

As humbling as it sounds, normal matter almost certainly accounts for the smallest proportion of the Universe, somewhere between \sf \red{1} \%1% and \sf \red{10} \%10% .

In the currently popular model of the Universe, \sf \red{70} \%70% is thought to be dark energy, \sf \red{25} \%25% dark matter and \sf \red{5} \%5% normal matter. But ESA’s X-ray observatory, XMM-Newton, has returned new data about this content. XMM-Newton has found puzzling differences between today’s clusters of galaxies and those in the Universe around seven thousand million years ago.

Some scientists interpret this to mean that the ‘dark energy’ which most astronomers now believe dominates the Universe simply does not exist.

Clusters of galaxies emit lots of X-rays because they contain a large quantity of high-temperature gas. By measuring the quantity of X-rays from a cluster, astronomers can work out both the temperature of the cluster gas and also the mass of the cluster.

Scientists believe that universe came from a big explosion and they called this Big Bang. Big Bang begins 13.8 billion years ago when the universe begins a tiny, dense, fire ball that exploded. In this treory explained where the universe begins of.
