Time is solid when it's what makes everything you could stub your toe on a second but matter just happens and it's unstoppable. For a rather simplified example of living in a universe constructed of time imagine a film real of every spot in the universe at every point in time all at once but you can only see the ones with in your curve of time, like how we all know there's a whole planet under us from the second we are born it's in our minds that this is the round solid curve. Time also exists on a curve but it's made of energy and acted upon by matter.
