Thsi is barely staying with the topic, but I'll post it anyway...

A really great book is A Wrinkle in Time by Madeline L'Engle.  Its science-fiction and its written for about a 7th grade reader, but I promise adults readers will also love it.  There are several follow-up books too and they are wonderful.  Time travel is an important part of the plot in these books.  Ever hear of a tesseract? :)

These are some of my most favorite books ever...

by the way rock hauler
u forgot to vote the correct answer



The answer is neither of course  :)

The 5 second delay by the party of the second relates to equal time in travel by the party of the first .

Did I win?    ;D

::)

Then again , if a rooster lays an egg on a roof that peaks at 53.8 degrees and has corragated roofing with a resistance of 1/3 inch per 10 feet , how fast would the egg roll and to which side ?

Hmmmmmm lets see here  ???

You dont need physics to solve the problem  ::)


The answer is : Roosters dont lay eggs hehehehehe

GOT YA    ;D

P.S. How did you intend to explain the answer to your question without physics? lol   ???

Just kidding  ;)

Understanding the concepts of physics is just as important as knowing the equations

My strong point is understanding why thing are the way they are... Granted i am good at math.. but i haven't delt with physics equations since 1995 and 96

I had to translate Latin recently and was in the ballpark , but I was at the football stadium and the game was going on in the baseball stadium. lol  


Just kidding my friend . I liked the topic and enjoyed thinking about the answer  ;D

how about this one rockhauler

3 dementional vaccum of space

You have a space craft capable of instananeous acceleration.  If you had to design a flight control system for this space craft how exactly would you do it?

What characteristics would you use based on modern technology?

I have an idea i think is very feasable.. curious what you would suggest and use

;D

Let me answer the original question with a question:
Are they both starting on earth and leaving it's gravitational pull?

If you remember Einstein's theory of time, he thought light was like a sonar, its the only way to view the passage of time. However, the rate which one travels through time would change invariably according to the amount of gravity exerted on the subject. That's why if you orbit the earth for a billion years you'd look and feel much younger than the billion year-olds on earth. But if you were to sit on something like oh, say a the sun for 5 seconds (put aside the whole survival thing), the poeple in space would view it as you being there for a whole lot less than 5 seconds (remember, you're aging slower in space)

The reason this could be pertinent is because if person A is waiting on earth 5 second before he goes, the rate at which he ages due to gravity is going to increase greater than being in a massless environment. However, person B would age at a much faster rate going 1/2 the speed of light than going the speed of light itself. So then it would be the question; how much did person A age while waiting doing nothing as opposed to person B going 1/2 the speed of light?

Oh no, I've gone cross-eyed.
The biggest and scariest ghost of all of them is the imagination

Hey I thought that according to einsteins theory of relativity he said that time didn't exist at all.(by the way I totally agree with that because my Spanish goes on for infinity even though its 50 minutes long

good puzzler!

my husband, who is an astrophysics brain working at a national lab with lots of other top-name physics brains needles me with these kind of puzzlers all the time.  

i'm glad you included this one.  i, however, could have told you that they were both the same age, but that is just because i was challenged with a similar puzzler about a year ago... by none other than my hubby.  go figure!
