¿Está la Tierra expandiéndose junto con el Universo?

¿Está la Tierra expandiéndose junto con el Universo?

La Tierra por sí sola no se está expandiendo al igual que los otros planetas del Sistema Solar, tampoco las estrellas de la Vía Láctea se alejan unas de otras.

Estos objetos que fueron formados bajo la influencia de la gravedad han cesado su movimiento expansivo.

La gravedad también mantiene juntas a las galaxias en grupos o clusters. Principalmente son estos grupos los que se alejan en el Universo unos de otros.

En otras palabras, cuando decimos que las galaxias se alejan unas de otras nos referimos a cúmulos de galaxias distintos, no a galaxias individuales dentro del mismo cúmulo.

Por ejemplo, en nuestro grupo local de aproximadamente 50 galaxias, todas ellas se mantienen unidas mediante la gravedad, incluso la galaxia de Andrómeda se acerca a la vía láctea. Es el grupo local en su conjunto el que se aleja de otros grupos de galaxias.
