Sunlight

[Multicell]

How long does it take for sunlight to arrive on your head...
Seconds, minutes, hours, years, decades?

Guess, do not look it up.

How about Moonlight?
How about the light of the Polestar?

What's a polestar

What's a polestar

It is a "poolster" in dutch translated and mispelled in english : - )

I ment Polaris. We call it here "the pole star"

[Multicell]

it is the brightest star in the constellation and is readily visible to the naked eye at night

DJEEEEZ that Polaris light takes a long time before it gets here... WOW
I didn't know that it was that long.

WHO knew this:
Although appearing to the naked eye as a single point of light, Polaris is a triple star system

Did you knew that ?

Wow

Perihelion: This is when Earth is closest to the Sun, which happens around early January. At this point, Earth is about 147.1 million kilometers (91.4 million miles) away from the Sun. Sunlight takes about 8 minutes and 3 seconds to travel this distance.

Aphelion: This is when Earth is farthest from the Sun, occurring around early July. Earth is about 152.1 million kilometers (94.5 million miles) away from the Sun at this time. Sunlight takes about 8 minutes and 30 seconds to cover this greater distance.

Anyone take a guess for a STAR, any star, not the sun (our nearest star).

 

[Multicell]

The furthest star visible to the naked eye is VY Canis Majoris, a red hypergiant star in the constellation Canis Major. It is located about ____ light-___ minutes/hours/weeks/months/years away from Earth.

 

[Multicell]

The nearest star to Earth, other than the Sun, is Proxima Centauri, located about _____ (light-time) away.

Same

Does it make a difference if you stand on a high point right under the moon or on a point far away at the north pole....

not really. I asked it A-idiot. it answered "It would take about 0.0703 seconds for light to travel the difference in distance between Mount Everest to the moon and the furthest point on Earth (at apogee) to the moon. This difference is approximately 70.3 milliseconds."

blinking our eyes takes about 100-400 miliseconds, average 300.

don't tell me that you knew this....
did you

you mogger

How long would it take for a pigeon to fly to the moon, if space would be just the same with air and gravity and all ?

How long would it take for a pigeon to fly to the moon, if space would be just the same with air and gravity and all ?

Assumptions:​

1. Distance to the Moon: ~384,400 km (average).
2. Pigeon’s average speed: ~80 km/h (sustained speed over long distances).
3. Constant flight with no rest: The pigeon never stops flying.

Calculation:​

Time=DistanceSpeed\text{Time} = \frac{\text{Distance}}{\text{Speed}}Time=SpeedDistance=384,400 km80 km/h= \frac{384,400 \text{ km}}{80 \text{ km/h}}=80 km/h384,400 km=4,805 hours= 4,805 \text{ hours}=4,805 hours=200 days(if it flies nonstop)= 200 \text{ days} \quad (\text{if it flies nonstop})=200 days(if it flies nonstop)

Realistic Consideration:​

Pigeons need to rest, eat, and sleep. If we assume it flies for 8 hours a day, then:

200 days×3=600 days≈1.6 years200 \text{ days} \times 3 = 600 \text{ days} \approx 1.6 \text{ years}200 days×3=600 days≈1.6 years
So, under these conditions, a pigeon could reach the Moon in around 1.6 years if it had food, water, and safe rest stops along the way.
