With the newly discovered faster than light speed, is there a theoretical minimum distance needed to travel...?

Question

,,,a minimum amount of time into the past?

For example, the scientists at CERN discovered neutrinos can go a matter of nanoseconds into the past over a distance from Geneva to Rome.

Since faster than light speed has been discovered, from what I understand, there's no science behind what the fastest possible speed it.

So, if a neutrino traveled, for example, ten times the speed of light over that same distance, it will have arrived more nanoseconds into the past. If it traveled even faster, the shorter amount of distance would be needed to travel to that same time. And so on, to, say, a neutrino traveling one hundred billion times the speed of light over a five meter distance.

Theoretically speaking, would this be accurate? I'm not saying such speeds are possible, but if they were, since we don't know the max speed now. And I aldo understand this only applies to neutrinos. I thought to myself that if that particle accelerator stayed where it is and somehow they make such speeds possible, then they can send lotto numbers to their earlier counterparts the previous day.

Answer 1

Well I think your real question is how they recompile things to be arranged in the same order that they were sent in. And where would I go to find free porn a day ago? Thats the big question!

Answer 2

By no means do we know that "light speed has been broken." It is almost certainly a measurement error. However, if it were found to be correct and "Einstein's Law" (we call it "Relativity") were violated, I wonder which theory you would expect us to answer this question with. After all, Relativity is our theory of motion. If we knew that it was incorrect, then we'd be pretty dumb to use it to answer questions such as this.



In the context of Relativity, however, faster than c transmissions don't go back in time the way you're thinking of it. The speed (faster than c or not) is still measured to be distance over time. The neutrinos still arrived in Italy AFTER being transmitted from Switzerland, not before. At least in our reference frame. They did not travel into our past. Nor would a neutrino traveling at 10c or 100,000,000,000c. By the very definition of what speed is, they would not.



Only in other reference frames, moving at high speeds with respect to the Earth, would it be observed that reception happened before transmission. And if reception happened aboard such a spacecraft with the right velocity, the pilot would conclude that he received the transmission before it was sent. Or, rather, he would likely not be able to tell whether he was the sender or the receiver of the message. Do this twice, sending the superluminal transmission to the fast spaceship, and having the spaceship send it back, would indeed send you lotto numbers before the drawing.

Answer 3

You are mistaken! The neutrino was measured to travel just a nanosecond faster than the speed of light. A nanosecond faster is not that much noticeably faster then the speed of light. It is by no way 10 times faster then the speed of light! And a hundred billion times faster - only in your dreams!



Besides neutrinos are mass-less particles that can't be used to transport your physical body anywhere!
