Complete waste of time to say JB could not have walked, jogged, run, cycled from GH to WHF and back during the hours of darkness when clearly he could have done:
It never gets truly "pitch black" at night primarily due to atmospheric scattering of sunlight and artificial light. Even after the sun sets, sunlight continues to scatter through the atmosphere and reflect off air molecules, dust, and humidity, keeping the sky faintly lit. Additional factors include artificial light pollution and faint cosmic background radiation.
Key reasons for the lack of complete darkness:
Atmospheric Scattering: Sunlight continues to hit the atmosphere and scatter in all directions, causing a twilight effect even after the sun is below the horizon.
Light Pollution: Streetlights, city lights, and suburban haze create "skyglow," which makes the night sky look brighter, especially near populated areas.
Natural Light Sources: Light from the moon, stars, the Milky Way, and zodiacal light (sunlight reflecting off interplanetary dust) contributes to the background brightness.
High Latitude Locations: In summer, places closer to the poles do not experience true darkness because the sun does not drop far enough below the horizon.
Atmospheric Composition: Dust and water vapor in the air can catch and reflect light, acting like a faint "lampshade" in the atmosphere.
Even on a "dark" night, the air itself emits a faint glow due to photochemical reactions, ensuring the night is rarely completely pitch black.
It's unusual for you to post a complete load of poorly researched rubbish Cc
Just so you know we get astronomical darkness when the sun sets more than 18 degrees below the horizon.
On such nights if it is clear I will be out in my garden with a torch setting up my telescope, and I do need a torch despite knowing my garden pretty well.
Obviously Bamber could go on foot, but cycling full pelt along a narrow path with steep falls either side I don't think so.
