How deep is the deepest hole ever drilled?

Question

I was told that when you own land, you own it all the way to the earths core...but then someone else said that you only own land as deep as the current technology can get to. So how far down is that?

Answer 1

"The initial target depth was set at 15,000 metres (49,210 ft). On June 6, 1979, the world depth record held by the Bertha Rogers hole in Washita County, Oklahoma (9,583 metres (31,440 ft))[2] was broken. In 1983, the drill passed the 12,000 metres (39,370 ft) level and stopped drilling for about a year to celebrate the event.[3] This idle period may have contributed to a disappointing break-down on September 27, 1984: after drilling 12,066 metres (39,587 ft) down, 5,000 metres (16,400 ft) of boring pipes tore off and were left in the earth. It was decided to drill again from 7,000 metres (22,970 ft).[3] The hole reached 12,262 metres (40,230 ft) deep in 1989. In that year the hole depth was expected to reach 13,500 metres (44,290 ft) by the end of 1990 and 15,000 metres (49,210 ft) by 1993.[4] However, due to higher than expected temperatures at this depth and location, 180 °C (356 °F) instead of expected 100 °C (212 °F), drilling deeper was deemed unfeasible and the drilling was stopped in 1992.[3] With the expected further increase in temperature with increasing depth, drilling to 15,000 metres (49,210 ft) would have meant working at a projected 300 °C (570 °F), at which the drill bit would no longer work."

quoted from wikipedia,  why don't people look up these things themselves

Answer 2

The white hole or the black hole is the deepest hole .
