Astronomers Still Look to Hubble Space Telescope

[CONCERTMANchicago]

Your dialog included Metric measurements during an English lesson which confused this American.

People learning English can teach us the Metric system. Unfortunately they must learn the outgoing standard of Imperial measurements first in order to communicate fully. It's ironic the world bases monitory standards on the American Dollar(and soon the yen, but after Euro failing, can a world standard for money ever work as good as Gold?)
