    That is why it is called the space time continuum. We cant see magnetic fields, but we can see the effects of magnetic fields. We can measure the forces of electric fields and magnetic fields. We can measure time.

    If you want to call the space time continuum something else , fine, but if no one else understands what you ate talking about, you ate unable to communicate and are isolated in your own subjective universe confused, scared, frustrated, angry and eventually powerless.

    Spacetime is not a "substance" in the scientific sense.

    It is only used that way in astronomy or physics as a figure of speech.

    And space is no more (and no less) a "substance" than time is.

    Even though Ether is an actual substance

    Space isn't a substance either. It is a... space.

    maybe not so tangible, but its evident time is a factor of space and they are inherently related ...

      No, it really isn't.

      I mean quite literally, the key conceptual paradigm change introduced by Relativity is precisely that.  Time is not "absolute."  It is "relative."

      This is a fact that is regularly confirmed through observation.
