Maybe I’m misinformed about this. But I was always told matter cannot be destroyed or created. But I have been told space is constantly expanding. Is this expansion of space not made up of “matter”? Where does it come from?

It s expanding in size, not in mass.

At the big Bang all matter was confined in one point.

After that it started yo expand , not necesarily increasing mass but volume.
