CORDOVA: Obviously I

CORDOVA: Obviously I cannot answer that without having those studies you mention looked at, and receiving advice. VERITAS: And who would be doing that looking and advising? LIGO? Would you be satisfied with more assurances from LIGO leaders? CORDOVA: I suppose a completely independent report could be commissioned from outside the scientific establishment. VERITAS: It would be a little late, wouldn’t it? The Nobel Prize has already been awarded and it is irrevocable. CORDOVA: We are not responsible for what the Nobel people do. VERITAS: I have no further questions for this witness, Your Honor. JUDGE: The witness may step down. This entry was posted on October 13, 2017 at 10:06 am 62

LIGO COURTROOM DRAMA: Trial Part 8 TRIAL PART 8 ON THE WITNESS STAND: Rainer Weiss (for the Defendants) VINO MOSCATO (Attorney for the Defendants): Professor Weiss, it is an honor to have you here. Congratulations on your Nobel Prize. Now, we know that you do not read stuff Dr. De puts out on the Internet or his book on LIGO. But at my request, you read that book before coming here. What is your reaction? RAINER WEISS: I believe he cannot understand that LIGO is a novel instrument which cannot be judged by conventional instrumentation concepts. MOSCATO: So is his entire book dismissible? WEISS: I believe so. MOSCATO: Is it correct to conclude that Dr. De is wallowing in his own misunderstandings in his book? WEISS: I think that’s right. MOSCATO: Thank you, Professor Weiss. I will not burden you further with this sort of thing. Your witness, Ms. Veritas. ASSUMPTA VERITAS (Attorney for the Plaintiffs): Good Morning, Professor Weiss. Let’s get right down to it. Does the LIGO instrument have an input signal and an output signal, and if so, what are they? Also, for the ease of understanding, let us use the term wiggle for signal. WEISS: Yes, there is an input wiggle and there is an output wiggle. The input wiggle would be a time trace of a number that is the linear size of something that is being sequentially contracted and expanded by the passage of a gravitational wave. The output wiggle would be this same wiggle as reported by the LIGO measuring system. VERITAS: And the two wiggles are different? WEISS: Yes. VERITAS: So, is Dr. De correct in describing LIGO as a two-port instrument with an input port and an output port? 63
