"Travelling Faster than Light" was the title of last night's BBC2 TV science programme. It seems that some neutrinos might act like tachyons and, therefore, travel faster than light. It was all speculative, as physicists poured over their charts and equations, checking, double-checking and cross-checking.
There are at least two phenomena that travel faster than light. Firstly, thought is faster, as thinking occurs instantaneously. The second faster-than-light phenomenon, according to a non-astronomical friend, is when a banker's fiddling the accounts. :lol:

If you had a lighthouse rotating beam bright enough to light a wall a thousand miles distant if the speed of rotation was fast enough the shadow and beam would move faster than the speed of light but nothing is actually moving on the wall. I think.

Actually I don't think that thought is instantaneous. The pathways between the neurons I think are accessed very fast probably as electric currents, but I think this takes time maybe microseconds or faster?
I will ask my expert neuroscientist friend what he thinks.
A lot of thinking here.

Thoughtful regards, David

The signals between synapses and neurons are electro-chemical, but thoughts are not. Thoughts are thoughts.

Well, that explains it. :wink:

Dear Brian and Joe,
I must consult an expert and ask his thoughts on the matter.
To me it would seem you cannot have a thought without recognising you are having a thought.
And I would think if you are recognising you are having a thought a signal is involved which takes time.
I don't think thoughts can exist without thinking ,again tortuous reasoning.
I don't think a thought can occur or 'exist' without recognising it is a thought. Without this I don't think it would exist.
I know nothing of these things and I am trying to apply reasoning to the matter. I suppose reasoning is also a thought.

Regards, David

Erm... Thoughts ARE signals.

Theres not some mystical force that skips that bit.

There's nothing mystical implied here. Obviously we need a brain in order to think, just as we need a gut to digest food.
Thoughts are not "signals". Thoughts are a synthesis of the brain matter interacting with the sense-data entering it. If there was no sensory data for the brain to work on, there wouldn't be any thoughts ( allowing for thoughts stored from previous experience as memory ).
Following a chain of sensory and electro-chemical events, thoughts arise instantaneously, i.e. faster than light.

But thoughts are a subset of all the information stored in the brain, of course only a tiny subset.
I think this involves cognition and signals. This subset does not in my opinion exist on its own, it needs signals to order it into a single thought, which then leads onto another thought maybe a different subset or an overlapping subset.
I am not convinced at all by your saying thoughts are instantaneous and faster than the speed of light.
Experiments with MRI scanners have associated different thoughts with different parts of the brain and the experimenter could identify what type of thoughts the individual was having.
I will discuss this with a neuroscientist next week

Regards, David

Where do they arise? And to where do they travel to be regarded as travelling faster than light?

Thoughts, following a chain of events, just "appear". Thoughts are ipso facto mental phenomena, so they don't actually travel anywhere, except when transposed into action as physical responses of the body, e.g., I see a physical ball as a thought form, then, respond physically by kicking the ball.

So how do they break the light barrier?

Hi,
After reading some of these posts several times the more cofusing it gets :?
Not very 'up' on this subject so whenever the question of 'faster than light-speed' comes up I just think of the quote by the great Muhammad Ali ..

"I'm so fast that last night I turned off the light switch in my hotel room and was in bed before the room was dark. "

I'll stick with that one :)

All the best
Dave

He probably could beat an old tungsten lamp.
He would need to be a bit quicker to beat a new low energy bulb when turned off.

Thoughts are beyond the light barrier to begin with, Joe. I can make a mental decision quicker than light travels over any distance.
Being instantaneous, thoughts don't have "velocity" like physical matter. As I said before, they simply occur. :D
