I find it amazing that we can "determine" the average temperature of a planet billions of miles away, but we still cannot predict the weather all that well.
72° F ? Sounds balmy, where do I buy the ticket? 600 light years away? No problem, I'll pack a lunch.
They visited a million years ago and found a bunch of monkeys throwing sticks and rocks at each other. They visited last week and the only difference was that the WEAPONS had evolved.
We would have to go well beyond the speed of light to get to these planets. The nearest star Proxima Centauri is 4.7 light years away. A light year equates to the distance of 6 trillion miles. With our current technoligy, it would take about 80,000 years to get the nearest star.

希望早日实现空间跳跃技术,估计这辈子是不太可能了。

20光年人类也永远无法到达。 3项发现均对人类无益。

I have an idea to overcome the distance. Just pack a vehicle with 4 men and 4 women and huge amount of food and water.After numerous generations human will be able to arrive the planet and colonize it.
