How old is the Universe ?

The Universe is everything we can see, and a lot that we can't see. It was created in the Big Bang explosion and has been changing and expanding ever since.

The Universe is just roughly 13.7 billion years early. and its start it looked nothing behind it does today. Yet, all in today's Universe did exist in some form message later. It all started following the massive bang, a nice of explosion that would not without help gore to fabricate all the event in the universe but with marked the begin of era


  • Creation of the Universe:-
  1. At the commencement, the universe was not and dense ball of radiation computer graphics.
  2. In one thousand  of a second, tiny radiation particles produced tiny particles of a situation. These amass to form the first ever chemical elements,  hydrogen, and helium.
  3. Some regions of the Universe contain slightly more hydrogen and helium than others. These shrank to form the first Star
  4. Nuclear appreciation inside the star produced many subsidiary chemical elements, including carbon and oxygen.
  5. The element in the universe today were produced from elements created in the Big Bang
  • How to: create the Universe
  1. Start era considering a Big Bang- a terrific explosion that lasts or less than one trillionth of a second that will make tiny particles of  radiation smaller than the size of a full decline
  2. Wait 380,000 years for the  first atoms to form a mixture that is 76 per cent hydrogen and 24 per cent helium
  3. After 1 billion years check that the first stars have formed, and there are dwarf galaxies throughout the universe.
  4. When the Universe is 3 billion years dated, merge together with little galaxies to form deafening ones.
  5. When 9 million years old, form our solar system in the milky habit galaxy

Bigger and bigger

Plantes
Earth may atmosphere big to us, but at 12,756 km (7926 miles) across, it is just a speck in an expanding Universe.

Stars
Planets orbit stars, our star is the sun. Without it there would be no life. It measures 1.4 million km (870000 miles) across.

Galaxies
Stars exist in Galaxies invincible star system that comes in a range of sizes and shapes. Earth is in the Milky habit Galaxy.

Cluster
Galaxies exist in Clusters, the milky way Galaxy is in the local group cluster, stretching 10 million fresh years across

Supercluster
Galaxy clusters are within the supercluster, we are in Virgo supercluster, 200 million spacious years from one side to accumulation.

Voids
The largest structure in the universe are chains of superclusters that are not speaking by big blank Voids

The summit ten chemical elements that make up the sun are:

  1. hydrogen                     71%
  2. helium                      27.1%
  3. oxygen                     0.97%
  4. carbon                        0.4%
  5. nitrogen                  0.096%
  6. silicon                     0.099%
  7. magnesium             0.076%
  8. neon                        0.058%
  9. iron                           0.14%
  10. sulphur                     0.04%

Hot stuff!

In the first trillionth of a second of its creation, the temperature of the universe was ten billion trillion degrees celsius.
