I just saw a few documentary in regards to life in other planets and space travels. My personal opinions – first Space travel exploration, possible? I say YES – Because look back at few hundreds years ago, it took human many months to a year to travel around the world, but then today, it took us hours, well maybe average 10hours to travel around earth with the faster airplane, there could be faster plane today though – So base on this fact, I say we can development light speed spaceship or faster than light speed, sometime near the future, even better we might be able to develop fold space technology or create a black hole that we can control, I’m not optimistic about it, I think we can, it’s a matter of time and resources and off course financial. In regards to life in other planets, off course, why not? – I believe Earth isn’t the only planet that support lives, there are many other planets out there have similar environment like Earth, the basic necessity for lives, water, oxygen and light – On the other hand, we defined life as such but what about Alien, how do they define life? How do we know that Alien are not living among us now? maybe life are smaller than we thought, such as organism, and ghost spirit, things that we cannot see but can feel, what if we are Alien? How do we know that we’re not? What if they’re invisible? so many questions with no answer.
