A giant thruster could be used to shift the Earth’s orbit as changes to the sun’s energy output increases

The video discusses a study predicting a drop in Earth's oxygen levels, threatening complex life. Astrophysicist Ethan Siegel proposes attaching a massive thruster to the South Pole to move Earth's orbit, countering the Sun's increasing energy output due to core changes. This would require immense energy, potentially from solar panels, and involve complex mechanics to propel Earth safely. The new orbit could alter Earth's path relative to space objects.

What is the proposed solution to prevent oxygen levels on Earth from dropping to unsustainable levels?

How much additional distance does Earth need to move away from the Sun to maintain current energy levels?

What energy source does Siegel suggest could power the thruster needed to move Earth?

Describe the mechanics of how the proposed thruster would work to propel Earth.

What are the potential consequences of moving Earth into the paths of other space objects?
