Sound Pulses Exceed Speed of Light

Depending on how you look at it, Barry Soeotoro was a great president.

Depending on how you look at it, Bill Clinton was a wonderful mentor to Monica Lewenski.

Depending on how you look at it, letting Mexicans overrun the country in a sign of love.

Depending on how you look at it, Houston just got a little rain.

Depending on how you look at it, physicist William Robertson at Middle Tennessee State University in Murfreesboro, along with a high school teacher, two college students and two high school students think we are all as dumb as a sack of hammers.

An observable response with science and scientific examples is that SOMEBODY knows this stuff! Like many others of us know about Pantone color charts, balancing fuel injectors, crocheting with long fiber cotton, or cutting valley cripple jacks freehand.

The specialized language is gobbledygook to the un-initiated, but plain-as-day to the practitioners.

The truly freaky part is that things like Relativity were theorized over 100 years ago, and one guy knew it.
Today, well-versed middle schoolers can give you the basics about it.

We do move forward, despite what some folks claim.

If you are no more than 187,000 miles from me as I type this, you are now, this instant, wondering where is that loud weird laugh coming from.

I find it doubtful that a professor from a lower to mid level college, a high school teacher and a few students were able to exceed the speed of light when no one else has.

Well, that explains the “kawoosh” noise when Marty McFly’s DeLorean goes through time.

Sorry! I seem to have met myself coming back.

Just to give some background on how not news this is, this effect was mentioned in the printed text for my Navy electronics school in the module on waveguides. This was in 1982.

Can you hear me now?

Oh, I love it...another BTTF fan. :)

The relativistic limit is most carefully expressed by saying that information can not be transmitted faster than the speed of light.

If one imagines a pair of scissor blades, or more simply a “guilliotine blade” falling along a straight blade, the point of contact may move faster than “C”, but it cannot transmit a signal of “yes or no”, say, from one point to another along this path, as it is all predetermined, you see.

I’m saying that any claim that the speed of light has been exceeded is ultimately equivalent to this example.

They’ll most likely find out their measurement devices were in error and go back to the drawing board.

"If one imagines a pair of scissor blades, or more simply a 'guilliotine blade' falling along a straight blade, the point of contact may move faster than 'C', but it cannot transmit a signal of “yes or no”, say, from one point to another along this path,"

An excellent example of a non-material "thing" moving faster than the speed of light, but is this the effect that they are measuring in their experiment? From the article I couldn't tell what was being done.

It sort of sounded to me like they were measuring two component waves of their overall sound starting at the peak of one component and then declaring the end to be the second component's peak - and then by adjusting the second component's form (moving its peak forward) they come up with a "speed" that is faster than c but really isn't a measure of anything real at all other than the relationship between two manipulated wave forms.

Kind of like moving the finish line forward in the 100 yd dash and then saying you set a new world's record. I hope the "scientists" had to spend their own money on their pvc pipes but I'd be willing to bet it was govt money financing this very important work.

Let’s not go to Camelot... It’s a silly place.
