How long would it take to travel through the Earth?

So far it has been thought that a journey from one to the other side of the planet would take about 42 minutes. Canadian physicist Alexander Klotz has managed to calculate the exact time it would take us to get through the center of the Earth, that is, through an imaginary tunnel to the other side of our planet.
For years scientists have been intrigued by the duration of journey through the "gravity tunnel," and there has been a theory that that travel would take 42 minutes and 12 seconds.
But in his new research published in the American Journal of Physics, Klotz saved us few minutes. Taking into consideration the density of the Earth's layers, Klotz calculated that a passenger through the center of the Earth would travel at a speed of eight kilometers per second, 23 times the speed of sound.
Therefore, it would take you exactly 38 minutes to get to the other side of the planet through its center. Given the position of countries, this means that we would travel much faster between Great Britain and New Zealand than Great Britain and Morrocco, for example.
