Strange

You seem to be confusing your crackpot ideas about autism with your crackpot ideas about homosexuality. Maybe they are both caused by the aliens lizard people who rule the planet. It is all a plot by the Illuminati. Why are you talking about vaccines. I thought this week's "cause of autism" was painkillers. What will it be next week, strawberry ice cream?

Science has answers to how it evolves and is a long way to understanding how it started as well.

It is totally idiotic. Presumably there is some sort of religious or other bigotry behind this.

Gherardi appears to be a complete crackpot, peddling bad science.

Even a laser will diverge. For example, the laser used for measuring the distance to the moon has a diameter of about 6km when it reaches the moon. The relationship between diameter, wavelength and distance is given by: [math]w^2(z)=w_0^2 \left(1+\left(\frac{z \lambda}{\pi w_0^2} \right )^2\right)[/math] The "size" of a photon depends what you doing. They are often treated as point particles. Or you can use the interaction cross section, but that depends what they are interacting with. You seem to be thinking of photons as classical objects, rather than having a probability distribution.

When things go wrong, is it always someone else's fault?

But whether you are measuring or calculating the diameter, you still need to define what it is that you are measuring/calculating. The beam does not have a sharp edge so there are multiple ways of saying what the diameter is. Your calculation (if it were possible) would need to match that definition. What difference do you expect pulses of single photons to make, compared to a normal laser.

Why would that make any difference? You still have to define how you are measuring the width. You would obviously need many of your single photon pulses to make the measurement. Are you asking if a photon has a size?

The value of the diameter depends how you define it: https://en.wikipedia.org/wiki/Beam_diameter#Width_definitions

Surely the diameter depends on all sorts of factors such as they type of laser, it’s size, the collimation of the beam, how far away you measure it. I’m not sure that the pulse rate would change this.

Nonsense. As we have gone from questions to full-on crackpot, I will suggest this is moved to the appropriate place. That might be its purpose, but it doesn't do it. You could build this, extract some of the power to stop it getting dangerous and sell that power to your local electricity company. Why isn't everyone (who believes this nonsense) doing this? Why isn't the electricity company doing this? I'm sure they would love to just have a couple of coils to give them free energy instead of having to pay for coal/oil/nuclear fuel.

It is four windings on a core. It can act as a transformer, if you use it that way. It can act as an inductor with some resistance. No it doesn't. You are certainly not getting both a higher voltage and a higher current.

Nothing can move at the speed of light. It would fly apart long before it reached anywhere near light speed.

I'm not sure. But neutron stars have quite complex structure. It could be that if it is close to the threshold mass, it takes some time for the system to "settle down" and collapse to sufficient density for the mass to be within the Schwarzschild radius. I guess because the second team had more time to use extra methods to clean up and extract information from the data. And, because this is a large collaboration, I assume these scientists are counted as part of the LIGO team. Maybe they should. But the original papers had something like three or more pages just listing the authors. More recent ones seem to be credited to "the Logo collaboration" or similar to get over that problem.

You can't copyright an idea. So if someone wants to implement the scheme you have described here, they are free to do so. Your system sounds similar to Q&A sites on the web like Stack Exchange or Quora. Do we need another one?

No they didn't.

How long has it been around?

Interesting idea. But, so far, the OP has claimed that this is a purely passive circuit (apart from the LED). If there is a transistor then that changes everything. So, @DARK0717 have you omitted to mention the detail of a transistor in the circuit?

As I say, there are too many variables to even begin to guess. But just the fact you are using batteries as a power source invalidates most conclusions you might draw, without a lot of careful work. I'm sure I have asked already: have you measured the resistance of the coil? No. I rarely watch videos. I am certainly not going to waste my time on something like this. If people like this had a source of magic free energy, why aren't they making vast amounts of money from it by selling energy and/or generators? Instead they are pulling people in to watch their videos and visit their websites so they can make money from advertising.

Fixed.

I can only assume that means that there are four independent coils and you have connected them as two pairs in series, something like this: But that does nothing to explain what you have measured. Trust me, homeopathy and horoscopes make more sense than that. (And they are both lies peddle by lunatics.) And just another thought, doing this sort of experiment with batteries is a bad idea because it just brings so many more unknowns in: internal resistance, state f charge, varying output voltage, temperature/time dependence of all the above. I don't think we can draw any conclusions from your measurements.

OK. So you did two experiments where you monitored the voltage and then for the rest you just measured current. Is that correct? And you always used the same set of batteries? As the only information online about such coils uscwritten by people who are insane, that doesn’t really help. Can you explain how the “input” and “output” lines are connected internally to the coil?
