101 Things You Need To Know

My sister borrowed this from her sch library and I found it very interesting! It coincidently covers the topics that I talked with my schoolmates today, like time travel, alien, light year, Pyramids, Bermuda Triangle...For those who are "science idiot" and lack of common sense, like me, it's really a nice book! Highly recommend!

- When we look at the stars from Earth we see it 4.3 years in the past.

- If aliens are out there, they must be further away than the 40,000 light years that have been examined by the SEFI(Search for Extra Terrestrial Intelligence) so far.

-A light year is a measurement of distance, not time.

...Go and flipflop it!
