Show SPACE. I With the airplane developing mar- i velous speed, and Marconi trying to I pick up a wireless message from Mars, your imagination suggests that some day flying men will travel out among the stars, exploring all nooks and crannies of the great space in which our universe floats like an escaped es-caped toy balloon. That day will never come, though men may travel to the moon, planets and nearest stars outside our bolar system. To travel from one end of the uni verse to the other an airplane would have to fly 186,300 miles a second for 1,000,000 years, according to latest guesses by astronomers. No one can picture an "end" to the universe. If there is an end, what lies beyond? Einstein says space (the uni verse) is curved, globular like a base ball. What's outside the circular ' limit? |
