Cuales son los descubrimientos mas relevante acerca de la estructura y evolución del universo

One of the most relevant discoveries is the Big Bang

Explanation:

The Big Bang can be defined as the moment when all matter resurfaces from nothing, that is, the origin of the Universe. According to this theory, matter was a very small point and it had a high density that exploded and expanded in all directions, generating the entire Universe. This happened about 13.8 billion years ago. After the explosion, the Universe began to cool and electrons, positrons, mesons, and the entire set of particles that are currently known were formed. Atoms were later created. Due to gravity, matter piled up to create clouds of the primordial elements. Some of these clouds began to rise stars and then galaxies formed.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
