It is hard to believe that our universe is actually expending considering how immense it already is. We still ask ourselves many questions that have remained unanswered by the famous scientists that have marked our cosmological history such as Einstein and Aristotle. For instance, how do black holes grow? Where does the universe take all of its energy to expand the way it does?
I therefore consider cosmology as a great mystery that humans have not yet discovered all about and maybe never will in the future. In a way, I feel afraid of space especially since we do not know enough about it to do what we want.
This may be beneficial for the universe since humans are unable to control it, which means that they cannot damage it unlike what they did to our planet Earth. The mistakes that were made on this planet in the past are irreversible and will forever remain a part of our eventful history. Many people today are still troubled by what has happened in their past such as the soldiers in World War II. This means that we must be careful with the universe so that we do not commit severe mistakes.
I will always remain impressed by astronauts who have devoted their lives to exploring space and testing new equipment to go into space without knowing exactly how it would react.
What humans know is that our galaxy called the Milky Way is located in stars and gas and is part of tens of thousands of galaxies. These galaxies remain unexplored by humans, which makes us question about whether there could be other life out there. Furthermore, since 1998, there is the idea that dark energy could be the source that is controlling our universe and also contributing to its growth.
I think the next big step for humans in space, even though many other achievements could be performed, is developing a way to be able to travel out of our galaxy to visit others. This idea is very interesting for me but it brings me to question whether we would ever know if our experiment worked or not. We must remember that the astronauts would be “traveling through time” because of the light years…

Recently, I watched a video by Bill Nye, the Science Guy, who was discussing his opinion about what is happening in space at the moment. He is the executive director of The Planetary Society which is a non-profit organization that promotes the exploration in space.
Their recent project is sending a spacecraft into space, no later than August 2014, which contains folded solar panels. When the craft will reach outer space, these panels (which are thin and pliable) will unfold. This is a brilliant idea since we could get energy from the sun without having to build huge solar panels that are very costly!
Also, this will allow us to maximize our space on earth because as we all know, our population is continuously growing. Consequently, we need more and more territory to live on. Therefore, getting our energy from space would be a good advantage for us.
It fascinates me how humans have the capability of progressing so fast in the scientific field. In our society, this is a very complicated branch which requires lots of thinking and analyzing.
Furthermore, I would say that space is one of the most difficult aspects of science since the amount of experiments that can be performed in space are limited. This means that scientists must rely on a minimum number of experiments to test their theories which is hard because the more data that is collected, the better a theory can be tested.
Lastly, it would be very interesting to follow up on Bill Nye’s organization in August to know whether or not this prototype will actually work or not. If it does, we can only hope to gain large amounts of energy from it.
