FTL light and EM waves are invisible

That makes sense.

John

I did not say it is totally invisible. It can be detected but only with appropriately design structure similar to the ones used in creating of FTL emission.

Mathew Orman

That explains why there are so many charlatans and quacks promoting it.

Just like theologians promoting their invisible god. Art

Don't care.

Build a device that demonstrates round-trip times of less than 85ms to the other side of the world, and then I'll be interested.

Sylvia.

Your crock runneth over. Art

What is the length of such round trip in miles or kilometers?

Mathew Orman

Approximately 25,600 km.

Or a bit too far for non-FTL communication to do it in 85ms.

Sylvia.

What planet do you guys live on??

Jeroen Belleman

I live on Earth. I have no idea what planet the OP thinks he lives on.

Sylvia.

I do not have the resources to cover such distance. But I will post a video of an experiment which will be in view site range of

2 km. At light speed it is about 6 us (micro seconds) one way and at 10 x FTL it should be 600 ns.

Mathew Orman

Ah, right. So a trip to the other side of the planet and back along the surface would be 40000km then. Minimum. No?

Were you around when this same fellow entertained us similarly in 2005? At the time he mistook a scheme like salphasic clock distribution for being FTL transmission. It *does* look that way, if you squint at it just right. ;-)

Jeroen Belleman

12,500 miles. Where were you when they were teaching this in school, or were you in one of those unionized schools that taught nothing but socialist propaganda and "Self-Esteem?"

Thanks, Rich

Not the flat one.

Thanks, Rich

What's that in kilometers, Rich, and how do you square that with Sylvia Else's post?

You're welcome, John

Yes, but any credible demonstration of FTL communication has to cover the shortest possible distance between the two points, not the shortest distance that currently implemented technology can achieve. A heat and pressure proof pipe throught he centre of the Earth could achieve 90ms.

I'm sure Internet gamers would be drooling at the idea of 90ms roundtrip times, but it wouldn't be a formal demonstration of FTL.

Just emphasises my point that actual FTL communication needs to be achieved by anyone claiming FTL operation.

Sylvia.

Rich has apparently overlooked the need for the signal to get back in a roundtrip scenario. He's also assuming transmission around the surface of the Earth.

Sylvia.

Of course.

I'm curious about your background, Sylvia. Have you anything to share?

John

Software engineering.

Sylvia.

Well, it is obvious that you are intelligent. By "Software engineering" do you mean you write it or essentially write the specs or both?
