Space Thoughts

It's said that 95% of space is still unexplored. So apparently we have explored 5% of space already. I feel it's far less than that. So in the vastness of space, is it really empty? Well, there is something called dark matter in space and it bends the way we see light so the actual objects shape is distorted. Dark matter is something that cannot be detected by normal means. There can be many things we just simply cannot see yet. Air is invisible to us, but it's still there.

We're using the Hubble space telescope that has been launched into outer space and that has brought us images but can we purely rely on those images? And in order to see an object it needs to have light reflecting off it. So if there are objects out there very far away from the sun then could we see it?

Also string theory tells us that what we think of as 'reality' is made up of 11 dimensions. They say the 11th dimension holds the key to faster-than-light travel. So if you believe in there being 11 dimensions, then we still haven't really explored what those 11 dimensions are and if they hold the key to answer other questions, possibly even time travel?

We may have limitations in our understanding now, but just thinking of the technology we have naturally and man-made astonishes me sometimes. I feel sometimes we may discount the discovery of being able look inside of a mothers womb to see what the growing baby looks like? Or how a dolphin uses the amazing ability of echolocation to navigate the oceans and can "see sound".

As for moving forwards in space travel, it brings me to a movie which I recently watched called, The Martian. In the movie, the astronaut played by Matt Damon was able to use his knowledge as botanist to grow food. In reality, NASA is planning a trip to Mars down the line but they are still figuring out if something like sustaining crops on the planet could ever play out for real. I feel that even if we can't physically be there for extended periods of time to test out these different ideas that we could use the technology of a robot and train it to be able to do certain actions on the planet to see if it could "live" in the way we'd need to.

I still go to bed with more questions than answers but without mystery, life sure would be boring.
