Einstein Rings

If Einstein defined this phenomenon, it must be an important one. I doubt the divine spirit would have prompted him to define it unless this was important for our understanding. That being said, why would this be important to humanity?

Not sure if Einstein knew the Holy Spirit, but how does any scientific observation of celestial objects benefit mankind, other than help us understand our own world? Or help us to keep exploring further out?

Depends on the subject. But not this one. Actually, if we're studying the cosmos in order to explore further with manned missions, we should perhaps create a moon base for refueling on long voyages. But, oh, wait, we "destroyed" the data and technology to send manned missions to the moon! Doh!🤦
