The average distance to the centre of the Earth is 6371 km, so
6371 km ÷ 20 km/h = 318.55 hrs
318.55 hours is approximately 320 hours, which is 13⅓ days.
Obviously this is theoretically speaking, and you cannot cycle to the centre of the Earth.
You would have to dig approximately 3,959 miles to reach the center of the Earth, but that's not realistically possible due to extreme heat and pressure beyond a certain depth.
You would have to drill about 5,100 kilometers below the surface.
No, it is not possible to reach the center of the Earth. The extreme heat and pressure at the Earth's core make it uninhabitable for humans, and our current technology is not advanced enough to withstand those conditions.
25,000 years.
Scientists cannot travel to the center of the Earth because the extreme heat and pressure would be fatal to humans. Additionally, the Earth's mantle and core are composed of molten rock and metal, making it physically impossible to physically reach the center.
In theory, at the center of the Earth you would have no weight.
We cannot go to the center of the Earth because the extreme heat and pressure would be fatal to any living being. Additionally, the Earth's core is primarily composed of solid metal, making it physically impossible for us to reach it with current technology.
It would take one hour to get to the center of the earth
The decrease in the value of 'g' when going inside the Earth is due to the reduction in the mass of the Earth below the point where you are measuring 'g'. This decrease in mass causes a weaker gravitational pull towards the center of the Earth, resulting in a lower acceleration due to gravity.

Diurnal cycle
No, it is not physically possible to drill through the center of the Earth. The extreme temperatures and pressures at the Earth's core would destroy any drill bit or equipment that attempts to reach it. Additionally, the distance to the Earth's core is far beyond the capabilities of current drilling technology.
