Sure they are.
However, you forgot about the discussion you had with a beam neutrino physicist six years ago.
He explained:
"The energy spectrum of the neutrino is a very strong function of the angle of emission. We can easily tell the difference between a couple of degrees.
We can easily tell the difference between 1 degree and 0 degrees by the energy spectrum we measure.
Your quite right the beam sprays all over the place. We confirm the angle by measuring the energy spectrum. As I say this can be done to within a degree. Especially as after 300km the difference between 1 degree and 0 degrees is quite pronounced.
We know where the source is and we can measure the energy spectra there and we know where we are detecting them and we measure them there. We can tell the angle between the beamline and the detector by the energy spectra of the neutrinos.

The two plots are the on-axis spectrum and the 2 degree (I think) spectrum.
The energy spectra tells you everything about the angle.
The spectrum actually comes from the decay of charged particles used to generate the neutrinos, not from a scattering interaction. Obviously neutrino scattering is negligable.
As for the laser pointer comparison, the neutrino beam is more like a laser, highly focused.
Before impacting the target, the original beam is highly focused through a magnetic horn, which results in an extremely narrow beam of particles, which results in an extremely narrow beam of neutrinos:
http://en.wikipedia.org/wiki/Magnetic_horn
How do we know the horn works? Because it has been tested by many experiments:
http://en.wikipedia.org/wiki/List_of_neutrino_experiments
In the T2K neutrino source, a beam of protons is accelerated to an energy of 50GeV, and are directed to a target area. The protons strike the target and produce positive pions (an many other particles), which are a type of positively charged meson. After the decay target is a magnetic horn that focuses the pions into a very tight beam. In an average of 26ns a pion decays into a muon and a muon neutrino. After the magnetic horn the neutrino beam spreads out due to the different possible angles that the muon neutrino can be emitted as it decays from the pion. Each of these decay angles results in a certain energy spectrum due to the particle momentum and other factors.
Because T2K is looking for evidence of neutrino oscillations, neutrinos at the 600MeV energy level are desirable, hence the experiment is conducted 2.5 degrees off axis. The energy of the neutrinos observed in the near and far detectors can be measured by the momentum of the particles produced in neutrino collisions.
The physics of the situation we have here is that a paticle decays into amongst other things a muon neutrino. A particle going in the same direction as the decaying parent will have the most energy. Although this is a decay not a collision, from the perpective of momentum conservation its pretty much the same situation, one particle gives its momentum to another.
Confidence is built due to the timing of the observations and the energy spectrum.
For timing in K2K identical atomic clocks were synchronized and driven to the two sites. T2K uses GPS timing as it is much cheaper than atomic clocks. The probability of a coincidence solar neutrino strike at both the near and far detectors drops as more neutrino events are observed.
The momentum and direction of the neutrino can be calculated from the interaction geometry. Commonly a muon neutrino will interact with a nucleus in a detector and cause the emission of a muon. This muon will have roughly the same direction as the neutrino and a predictable momentum. The detector is surrounded in a magnetic field, which causes the muon to deflect, and allows its momentum to be measured. There are several other techniques to measure the momentum but that is the basic one.
In T2K the primary axis of the beam is directed 2.5 degrees below the near detector. On axis, the mean neutrino energy is 2GeV, whereas the mean energy 2.5 degrees off axis is 0.6Gev. Most of the near detector is lined up at 2.5 degrees off axis, but the INGRID detector is in a plus shape centered directly on axis with the beam. The INGRID detector can be used to verify that the beam is pointing where it should be, and that the energy spectra is as expected.
The energy spectra is measured again in the far detector Super K. Here the Cherenkov radiation of the interacting neutrino produces a ring of light on the inside of the Super K chamber, which is lined with photomultiplier tubes. Due to the timing and shape of the ring the energy and flavor of the neutrino can be determined.
The experiment can easily tell the difference between a couple of degrees. The effects its trying to measure have a far more subtle effect than that. We use detectors very close to measure the energy spectra accurately. This can then be compared to the far detector allowing a confirmation of a number of physical phenomena, including but not limited to the angle of the far detector with respect to the beamline.
If the Earth was not round then these experiments would not work because the difference between the assumed geometry of the Earth and its true geometry would be a much larger effect than the aims of the experiment.
The beam neutrinos experiment and the neutrino detection from below the Earth is totally devastating to the FET.
The resident experts who make media engagements cannot explain these facts at all.
I hate to be the burster of bubbles here, but couldn't the neutrinos just curve up when inside the earth? How can we confirm they travel straight through matter, specifically the earth's insides whatever they may be?They're traveling at close to the speed of light. If they were accelerating that much, then they would oscillate slower.

The experiment was repeated with 24 different
arrangements of conveyor speeds, fiber lengths, and the three different FOC configurations shown in Fig.1.
The conveyor speeds were between 3 and 9 cm/s. The loops had perimeters of 2.5, 4.0, 8.0, and 16.0 m; in each case there were three turns of the fiber wound on the loop.
As shown in Fig. 3, the phase shift or the traveltime difference between two counter-propagating light beams in the moving optic fiber was clearly observed in all different configurations of FOCs. The phase shift Δφ, and therefore, the travel-time difference Δt are proportional to both the total length and the speed of the moving fiber whether the motion is circular or uniform. Other tests using smaller end wheels for the FOC and fiber loops with additional curves also confirmed the same finding.I omitted the text of that "Third proof", just to save space. As far as I know, nobody argues against the fact that "Professor Wang's seminal paper did prove that the Sagnac applied to linear motion".
Professor Wang's seminal paper did prove that the Sagnac applied to linear motion.
Third proof:
Note that Wang, Zheng, and Yao state " the relative linear motion between two objects".(https://www.dropbox.com/s/s9s9jfa9m9f1z23/Generalized%20Sagnac%20Effect%2C%20Ruyong%20Wang%2C%20Yi%20Zheng%2C%20and%20Aiping%20Y%20-%20Figure%203a.png?dl=1)This generalization provides a design principle for a new fiber-optic linear motion sensor (FOLMS), which has a high sensitivity and a high stability. The basic structure of this sensor can be similar to that shown in Fig. 3(a). The linear motion of the top arm of the sensor is detected with a phase difference Δϕ = 4πNΔl/cλ.
Fig. 3(a)
Because two beams share the same optical path, the sensor is optically stable. Just as a FOG detects the rotational motion of an object, a FOLMS can detect the relative linear motion between two objects fixed on the top and bottom arms of the parallelogram.

Pretending that satellites do not exist, even though you do use the GPS system, won't help you.I don't follow. How would a Sagnac Loop detect the CORIOLIS EFFECT?
HERE IS A VERTICAL SAGNAC INTERFEROMETER, which immediately records/registers ANY upward or rotational motion:

The ONLY effect detected was the CORIOLIS EFFECT, nothing else.

And yeah, they would both end up getting banned. Maybe not in 24 hours, but I know Rab has a ban or two over there. Jackblack wouldn't bother trying over there, as he would be severely outmatched in math/physics by Parsifal, Pete, and Thork (and likely more I am not even thinking of at the moment). It would be a bloodbath, so he probably would get banned for resorting to shitposting when he is getting smashed in a debate.

The topic is Neutrinos, so to avoid further unnecessary clutter go and read the reply to the Sagnac part in Sandokhan Generalised Sagnac. (https://forum.tfes.org/index.php?topic=9793.0)
Bye bye.
rabinoz has already resorted to shitposting and plain trolling right here in this thread....sandokhan, I agree with you in this instance. Please use the report button in cases like this, as I don't always view every post in every thread. I would also suggest just reporting and moving on, without calling him out. It is giving him the attention he seems to crave. If you report posts and aren't seeing a response, then feel free to PM me or another moderator.
Somebody has to step in and inform this user that he can no longer use trolling as a basic path of least resistance to obfuscation, which he is intentionally doing on a regular basis.
