We know that a trip to the center of the Milky Way is impossible with the science we know today. The galaxy that inhabits our Solar System it is wide and extensive, and we are in a remote region of its revolving disc.
However, since the idea is to know the calculations and not to plan a trip or reserve a hostel, let us know scientifically how long it would take us to reach the center of the Milky Way and appreciate our black hole up close, without being trapped and consumed.
First of all, let’s know how big our galaxy is. The Milky Way, in general lines with its changes and movements, has a diameter that goes between 100 thousand and 120 thousand light years. In other words, crossing it from end to end at the speed of light would take us that entire period.
But beware that we are not at the extreme, nor are we going to the other edge. The trip is towards the center of the galaxy. This region of the Milky Way is located at an approximate distance of about 25,000 light years from Earth.
So, having the speed of light resolved, with everything and application, it would take us 25 thousand light years to reach the center.
That is impossible with current science. Einstein’s theory of relativity says that no object with mass can travel at or above the speed of light in a vacuum (which is approximately 299,792,458 meters per second). This means that moving at that speed would be impossible according to our current understanding of physics.
The most we could achieve would be a significantly smaller fraction of the speed of light. For example, if we could travel at 10% of the speed of light (0.1 times the speed of light). So when doing the calculations, we would get a time of approximately more than 83 million Earth years to reach the center of the Milky Way.
