Respuesta :
The  big bang theory or great expansion explains the formation of the universe from a point with very high density where matter and space were created, it can be observed in an experiment
The Big Bang theory that can be adapted with some home experiments, specifically the expansion can be measured using an experiment with inflating balloons.
Materials
deflated balloons
marker
thread
measuring tape
Description of the experiment
The stars or galaxies are marked repeatedly with an initial separation and this distance is measured by a thread the length and the thread with a meter, this is used as measured by the fact that the surface is curved.
The balloon is inflated and measurements of the separation are made, observing that as the volume of the balloon increases (time increase) the separation of the galaxies increases
The increase in distance is explained by the Big Bang theory or great expansion.
There is also astronomical evidence:
* The redshift of the hydrogen spectral lines that is explained by the Dopler effect, which is a move away from objects
* Background radiation in the microwave range that comes from everywhere and would be the residue of a large initial explosion.
