Which statement accurately describes the universe?
the universe consists of all the energy made by the sun and stars.
the universe consists of all physical objects on earth and in space.
the universe consists of all matter and energy.
the universe consists of solar systems which contain galaxies.

Out of all the photos scissors for the given question on Universe the third one is true.

Explanation:

The universe is completely made up of matter and Energy. Since this statement is true; hence these are the only two. Elements that remain correct in case of conservation.

Any matter that is present in nature would transform into lower to higher masses with absorption on release of energy that is even matter is made up of energy.

And energy present in the complete universe everything from stars to planets to asteroids are made up of mass and energy which only transforms its faces and never gets destroyed.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
