its been emphasised to me by teachers that space is Empty vacuum, is it really?
Einstein indicates that space curves,but if its vacuum ,and a vaccum is empty nothing .
Than if follows that Einsteins equation is based on its curvature?
I try to be logical ,but its so confusing?
Widows n orp post below; dont feel bad we are all in the same boat. that why I ask questions ,i no know it all!
The universe is theorized to contain dark energy and dark matter. There have been some confirmation of it's existence but really just speculation at this point. The idea of dark matter had been identified by Einstein but it wasn't till the discovery that the universe is accelerating it's expansion and contains up to 70% more matter that the idea of dark matter and energy became serious areas of study. If you mean a vacuum to mean absence of air it is a vacuum but within that "vacuum" there definitely is matter.
