Traveling through outer space and seeing every galaxy in the observable universe would be an extraordinary feat due to the vastness of the universe and the limitations imposed by the speed of light.
The observable universe is estimated to have a diameter of about 93 billion light-years, which means the light from the most distant objects we can observe has taken approximately 93 billion years to reach us. However, it's important to note that the universe has been expanding during this time, so the current size of the observable universe is larger than the distance light has traveled since the Big Bang.
Now, let's consider the speed of light, which is about 299,792 kilometers per second (or approximately 186,282 miles per second). This is the fastest speed at which information can travel in the universe.
Given these factors, even if we were able to travel at the speed of light, it would still take an immense amount of time to visit every galaxy in the observable universe. Moreover, the expansion of the universe would cause galaxies to move farther away from us, making it even more challenging to reach them.
Additionally, there are other practical limitations to consider, such as the finite lifespan of humans and the technological capabilities required for such vast intergalactic travel.
In summary, due to the immense size of the observable universe, the limitations imposed by the speed of light, and the challenges of intergalactic travel, it is currently not feasible for us to travel through outer space and see every galaxy in the observable universe within a reasonable timeframe.
