Controversial Everest Ascent: Xenon Gas Used in Record Climb
A group of British climbers climbed Mount Everest very quickly, using a special gas called xenon.
Normally, climbers spend weeks adjusting to the thin air, but these climbers used xenon to help their bodies adapt faster.
This has caused a big debate because some people think it's not fair or safe.
Experts disagree on whether xenon really helps and if it's safe.
Some people worry about the ethics of making climbing easier, and whether it takes away from the challenge and the time-consuming preparation.
The Nepalese government is investigating the use of the gas.
A British expedition climbed Mount Everest in record time using xenon gas to acclimatize quickly.
The expedition's speed and gas use sparked debate and an investigation by the Nepalese government.
Some experts believe xenon can help acclimatize to high altitudes, while others doubt its effectiveness and safety.
The use of xenon gas is considered by some as against climbing ethics and may reduce the role of Sherpas.
The expedition organizers plan to offer two-week excursions using xenon gas.
