Stupid question! Assuming we could get it spinning at the speed of light, how would you ever get a 10^9 meter prop on an airplane? Use common sense here.

And what the hell does that have to do with steak? I advise you to edit your post before lock/ban.

:)
i took it as he were talking about the steaks being put on a plane



STEAKS ON A MFKING PLANE!


hmm can God make a steak so big that even he couldnt eat?

I don't see how this would differ from any other case of accelerating to the speed of light. The faster the blades rotate, the harder it becomes to continue accelerating them.

The mass increase I can understand. But how do you reconcile time dilation and foreshortening?

Time dilation would occur as with any other object, the faster it rotates, the more significant the impact. I don't see how that would open up the possibility for it to travel faster than light. Same for 'foreshortening', if I understand correctly that you're referring to length contraction.

The phenomenon applies to any moving object much like the rotating blades, but it doesn't leave any theoretical gap for the blade to exceed the speed of light.

HEY HEY HEY! stay on topic!



mmmm.... steaks

Pardon my insane lack of understanding when it comes to this, but doesn't relativity say that as you increase and object closer to the speed of light, it's mass becomes greater? And the more mass, the more energy required, so eventually you would reach a point where the object has infinite mass, thus requiring an infinite amount of energy, which is impossible? Just trying to pull some physics I learned to good use...

With those little red potatoes...smothered in butter....yummm

Ever been to a Brazillian steakhouse? Where the Gaucho's come out and carve succulent meat onto your plate? Texas De Brazil is AWESOME....the garlic encrusted filet, just a little pink, was excellent.

You thinking Argentina maybe?:confused:

muahahaha.... steaks on a plane.... hahahaha... u guys are insane. :)

on the other hand, i could really do with some peppered steak right now. with buttered potatoes.... yumm...

why would someone ever want to spin a blade to cut steak, i dont know!

Hmmm...I bet the friction from the spinning blade would sear the steak, sealing in flavor! It is a good idea, and it just might work....
The water in the meat would slow down any such temperature jump.

Also, isn't it uncanny that you look exatly like your avatar?

they modeled it after me

That is quite apparent. Did they model Howard's avatar after him?
I need my own avatar

OK, wait, I've got a question. Since increasing an object's speed to infinate mass requires infinite energy, that means you can only do it once right? That means you can only expand ONE piece of steak to infinate mass. This means only ONE cut! So, which cut do you send past the speed of light? I VOTE FILET MIGNON!!!!!!!!

No it doesn't. It says that the momentum increases. But, most people interpret it as mass.

(ooops, I sent a response to the wrong thread)

And, my response to this thread went to a different thread, and so on..

Incidentally, I found the question to be a nice mental puzzle, that is, if you want your brain to fry.... Imagine two people standing on the platter... one close to the center, and one toward the outer edge... (well, he's strapped in, realllly good.) Of course, it's a hypothetical question as the centripetal acceleration would tear him to shreds. But, in terms of time dilation, his time should be running slower than the person's time who is closer to the center... But, they both have the same number of revolutions per second... Aaaaghhhh!

With reference to what? If they are not moving relative to one another (aka if the person close to the center of the disk is any distance away from the exact center) then chosing a reference point of one of the people wouldnt make a difference at all with time dilation. If you chose your reference point to be the center of the disk and keep it stationary (aka non rotating) then time dilation comes into play with both people. Because the person farther out would have a larger liniar velocity than the person closer to the center, then from the stationary reference point in the center his time would seem to move slower. The person closer to the center would also experience some time dilation but because of the drop in linear velocity his would not be as obvious.
