Physical world has its own limitation compared to a spiritual world which is eternal.
Could the two (physical and spiritual) meet and fuse?
I would say yes based on my faith , knowledge and experience.
A human being for example has a physical and spiritual being, a body and a spirit (soul).
Based on my faith, knowledge and experience, God created man from the dust then breathed the man for existence.
So the man is composed of physical (dust) and spiritual (breath).
Then the LORD God formed the man from the dust of the ground. He breathed the breath of life into the man's nostrils, and the man became a living person.
Genesis 2:7
