My general relativity mind says no, since speed of light is constant in all inertial frames of reference.

But maybe u have an alternate theory...

"ACHTUNG ACHTUNG!! ZER SPELLING NAZI IS ON PATROL"
Nein, boet 'Achtung x2, der spelling Nazi ist auf Patrol' ist cloo$er I zink ;-)

But Jon, "Is this scenario possible?" - Yes.
You're right in assuming he'll see a flash once per second, the only thing is that the light he sees is exactly a year old - which means there's a whole pulse-train on it's way to him.
The light emitted acts like a widening spiral perpetually widening with (duh) lightspeed, quite like the groove in an LP (you old enough to remember that? :)

Exec, the light he sees travels at normal lightspeed, never mind with what rotational speed the lighthouse spins at. However, it'll be a very short flash, visible only if the 'powerful laser' is indeed that, powerful enough - but that wasn't the question.

Porra , jirre man, jou vorige opmerking 'gaan weeg jouself inni swembad' het hoop geskep, dis mos buoyancy, not so? Reg in elk geval, maar boggeral van doene met swaartekrags verskille.

Afrikaanse raaiseltjie nou:
Drie hoere sit in n kroeg. Omrede dat name op hierdie site gevoelig kan wees noem ons hulle gemakshalwe maar A, B en C sodat niemand ongelukkig kan raak nie. A sit en lees n Afrikaanse populere boek, B drink n Bier, en C speel met haar foon. Ook, A is in haar twintigs, B is ma van twee en C is skeef. As ander info kan ek noem dat A blond is, B het n graad in geskiedenis en C besit n kar.
Watter een verjaar?

Ok Chmoks, I dont quite agree but we can argue that around a braai and beers.

In the mean time: more please! I find this thread intellectually stimulating *thumbs up*

Watter een verjaar?
Hoera!


Anyone knows what the flame of a candle looks like.
Will it, in a breathable atmosphere, look different in a weightlessness environment?

Will not give the answer unless someone tries.
And, if A is correct it will be your turn to ask a Q ;-)

The flame will die due to no convection. It will basically suffocate itself ;-)

Spherical in a no gravity environment...

It is what is/was expected, but it doesn't.

..... and?? A rather peculiar bit is missing...

The flame becomes blue and the shape of the flame is like a dome

1. A man was going to bleach his socks because they had gotten muddy the day before. As he was pouring the bleach into the washing machine, he spilled some on the floor. He got some cleaning fluid and mopped it up with a rag. Minutes later he was dead. What killed him?


2.What demands an answer but asks no question?

3. A bus driver was heading down a street in Colorado. He went right past a stop sign without stopping, he turned left where there was a "no left turn" sign and he went the wrong way on a one-way street. Then he went on the left side of the road past a cop car. Still - he didn't break any traffic laws. Why not?

Spherical blue flame as it burns more complete due to lack of thermosyphon turbulence - which will indeed choke the flame of new oxygen to a certain extent. It appears though that enough oxygen finds its way due to migration/diffusion so that the flame continues to burn. All this is a major concern for detecting & fighting fires aboard spacecraft.


Thanks Smirnoff, I'll not google.

1 - What killed him?
No ordinary products will kill him as the chlorine is too diluted/weak in bleach, but I hunch you mean a chlorine-ammonia gas produced as the result of an acid added to a caustic solution.
That, or an allergic reaction.

2 - a situation.

3 - he's driving in a bus-lane (Pretoria's A Re Yeng does similar things)
