Could you travel center of the Earth?

No, it is not possible to travel to the center of the Earth. The Earth's core is extremely hot and dense, with temperatures reaching over 5,000 degrees Celsius (9,000 degrees Fahrenheit) and pressures reaching over 3.6 million atmospheres. These conditions would quickly destroy any known material or technology. Additionally, the extreme gravity at the Earth's center would make it impossible for any object to escape.
