No, the Burj Khalifa does not reach the point of the troposphere.

Here's why:

* Height of the Burj Khalifa: The Burj Khalifa is approximately 828 meters (2,717 feet) tall.

* Height of the Troposphere: The troposphere, the lowest layer of Earth's atmosphere, extends to about 7-17 kilometers (4-11 miles) in height, depending on latitude.

Therefore, even at its tallest point, the Burj Khalifa only reaches a fraction of the troposphere's height.
