I watched the video Bestvalue refers to about light speed. There's quite a lot of and this is what I've found so far.
He complains that science is influenced by a world view that is essentially "materialism" Which is basically seeing what is there rather than what you'd like to be there.
He has 10 things that he thinks we say that we are wrong about.
#1 'The universe is machinelike'. He is objecting to cause and effect. I suppose it would be interesting if you dropped a stone and instead of falling to the ground it turned into a bowl of Petunias (thank you Douglas Adams). I'm afraid that our view is supported by evidence and experience.
#2 'Matter isn't conscious". He would have us think that trees for example are conscious which doesn't sound too bad, but then by his argument so is that pencil, that toilet roll and that small rock. He should have invited a small pebble along to speak on his behalf. Might be a problem for people that as it would mean your skin and your thumb had it's own consciousness
#3 "Laws of nature have never changed since the big bang". Not my area, but probably best if gravity doesn't stop working on Wednesdays and it hasn't so far. Hands up anyone who has noticed physical laws changing.
#4 "Total of matter and energy is the same". I'm no expert but if he is saying energy goes away where does it go?
#5 "Nature has no purpose or plan". Well as much as he might like to think that the clouds rain on you on purpose it doesn't work that way.
#6 "Everything you inherit is in your genes". What else would you inherit? Even Christians don't claim you inherit your soul from parents.
#7 "Memories are stored in your brain". Where else? in a cloud? In God's notebook?
#8 "Your mind is inside your head". Well clearly his is lower down so I guess we are sometimes wrong.
#9 "Psychic phenomena don't exist". I wouldn't rule out say 'Telepathy', but if it existed then it would one day be explainable in terms of energy fields and therefore wouldn't be 'psychic' (which is just a more respectable sounding term for 'magic'). Also we do investigate such things. We don't dismiss them out of hand.
#10 "Mechanistic(physical) Medicine is the only kind that works". Alternative medicine just doesn't (aside from the placebo effect which is not really the medicine working). Trials are conducted all the time and if any do work they are no longer alternative. And btw we do have therapy and such, but I guess he doesn't know that.
After listing those he says that he looked up old books and the speed of light was different. He thinks this is a revelation, but it's not news to most people.
The speed of light has been measured many times with increasing accuracy, Gradually we got better at it and it got closer and closer to the speed we know today.
I don't have a link handy, but I vaguely recall reading that if it really had been increasing at that rate then 'Adam' would have been able to outrun it.
He complains that all these things that he disagrees with are the default position of all educated people. I can only suggest that this is a hint he might want to consider carefully.
