Chapter 651

Question.

How long does it take for a beam of light to travel from Nepal to Niuyuecheng.

The speed of light in a vacuum is constant, about 300,000 kilometers per second.

Although it is currently in the atmosphere, the degree of decay in the speed of light is almost negligible.

And Nepal is about 12,000 kilometers away from Niuyuecheng.

So...

It takes about 0.04 seconds for light to travel from Nepal to Niuyuecheng.

Hawk is the same.

Just as Gwen had just hugged Hawk tightly, thinking about letting Hawk fly faster, before she could even speak, she saw the familiar big tree and the familiar flowers and plants.

She was stunned.

Hawk looked at Gwen, who had her mouth wide open, and raised an eyebrow.

"What's wrong?"

"You..."

Gwen subconsciously looked up: "I... we're back already?"

Hawk smiled slightly.
