Topic: Space Technology.

Know-How Mechanism (Prelims):

• Rotating black holes have an area outside their event horizon known as the

• The term “ergo sphere” comes from the Greek word “ergon” meaning work.
• Scientists propose utilizing the ergo sphere to accelerate objects by sending them into it and allowing them to gain speed.

• Utilizing the ergosphere could potentially accelerate objects by sending them into it and allowing them to gain speed, resulting in the black hole losing some angular momentum.
