Size of the Universe

Another video that puts the size of the universe into perspective.


It's common to feel insignificant after watching videos such as these. After all, we are unimaginably small when compared to our cosmos, and seeing it on this grand of scale can be frightening. We feel centered and significant when confined to our own solar system around our sun. Yet there are still countless more stars in the universe than there are grains of sand on earth!

        So what does this mean for us as humans, as we live our lives daily. Does this mean that we are insignificant, worthless, and meaningless creatures that were an anomaly of space, time, and matter? Does it mean that we are simply pre-programmed particles, sending electrical pulses between brain neurons to control how we act and think, creating an illusion that we have conscious thought? This builds foundation for what I believe are the two most basic and essential questions of life.
       1. How did we come to exist?
       2. Why did we come to exist?

        These two questions I believe are the foundation behind the knowledge needed to fully understand the correct way to live here on Earth (if there is one). Over the next few weeks I will be introducing more videos and text to explain why these two questions are the essential questions of life, and also to demonstrate the strides that modern science has made in answering these questions, while explaining the setbacks caused by religion.

Size of Stars

Here's a cool video link displaying the size of stars in our galaxy.


The Age of the Universe

This blog is going to cover a wide range of topics. Predominantly, facts of science and the tremendous strides modern science has had in explaining our universe.

For example, I find it fascinating that the universe has been calculated to be roughly 13.7 billion years old. What's astounding is when this number is put into perspective to allow us to understand it more fully.
         Consider the facts that the universe is 13.7 billion years old, and that homo sapiens have existed for roughly 200,000 years. Now imagine that the age of the universe is scaled down to one calendar year. Every day of the year represents a time period of roughly 38 million years. What is incredible to think about, is that this would proportionately mean that the human species did not exist until the last couple minutes of the last day of the year. All of recorded history and everyone ever known to people on this earth, only existed in the last seconds of the entire calendar year. Crazy to think about!
