Thread: Riddle Me This, SRP

Two trains are heading directly toward each other on adjacent tracks.
Roger is on one train traveling at 100 metres per second (mps) and Greg is on another train traveling at 200mps.
Roger has a lamp. The speed of the light from his lamp is 299,792,458mps.
Additionally, Roger is also running at a velocity of 10mps on his train in the direction that the train is travelling, in the direction of Greg.

At what total speed is the light from Roger's lamp traveling toward Greg?

Sorry x, I skipped the rest of the details. If you'll allow me to assume that the speed of light is as you say while traveling through the same medium, then the speed of light is constant and does not change so I guess the answer to the riddle is 299,792,458mps

That's right Lee. The speed of light is a constant, unchanging.

Unless it is going slower of course, heh heh

Hmm.... I must think of a riddle now

If two spacecraft move apart, each at speed 0.75 of the speed of light, their relative speed is 1.5 times the speed of light. Yet physicists claim that each each can see the other moving away at 1.5 speed of light despite light itself only moving at one times the speed of light.

My question is how do physicists get away with these nonsenical theories?

Rhetorical question, not a riddle for the thread.

What you do is, you create a model of how the Universe works. Then, you code that into a computer. Then, you simulate. Then, you notice your simulations are not quite right. So, you tinker some more with the code. Then, when it appears that you cannot fix it, you decide to give the difference between what you expect and what the computer spits out a name, like so:

"Eggbert, what shall we call the discrepancy in our computer simulations?"

"Well Dexter, it is a real bugger and very annoying. Why don't we call it the 'we don't know Sh*t' discrepancy!!"

"We can't use the word 'sh*t' Eggbert! We are serious scientists! People look up to us. We need another word."

"Hmmm, another word for 'sh*t', hmmm. I have it Dexter!! Let's call it Dark Matter instead!"

"Brilliant Eggbert.! Our names will go down in history! And, it will be fun watching future generations of Physicists out trying to prove Sh*t! I mean, Dark Matter."

I got another one to toss in here, might be relatively easy though

A cowboy rides into town on Friday, he stays for four days and 3 nights at the saloon and leaves on Friday.... HOW????

He spent 3 days and 4 nights elsewhere in town.

OR

The horse named Friday.

The horse of course !!!!

There are five houses in five different colours in a row. In each house lives a person of a different nationality. The five owners drink a particular beverage, smoke a certain brand of cigar, and have a certain pet. No owners have the same pet, smoke the same cigar, or drink the same beverage. Other facts:
1. The Brit lives in the red house.
2. The Swede keeps dogs as pets.
3. The Dane drinks tea.
4. The green house is on the immediate left of the white house.
5. The green house's owner drinks coffee.
6. The owner who smokes Pall Mall rears birds.
7. The owner of the yellow house smokes Dunhill.
8. The owner living in the center house drinks milk.
9. The Norwegian lives in the first house.
10. The owner who smokes Blends lives next to the one who keeps cats.
11. The owner who keeps the horse lives next to the one who smokes Dunhill.
12. The owner who smokes Bluemasters drinks beer.
13. The German smokes Prince.
14. The Norwegian lives next to the blue house.
15. The owner who smokes Blends lives next to the one who drinks water.


The question is: WHO OWNS THE FISH?
