Challenge to youtubers - make an experiment demonstrating that increasing the concentration of CO2 in parcel of air from 00.029% to 00.038% has the effect IPCC claims and that it will bring the temperature up by the IPCC claimed amount of ºC WITHOUT increasing the energy input.

What if you sync 2 lasers to light at the same time each with a vacuum in front of them and in one vacuum you put a clock to measure the light going in one direction, then in the 2nd vacuum you put a clock by the laser so the light has to travel back and forth and see if you get the same time period if you double the first clocks time?

Couldn't they use two mirrors ? The light starts from the clock and go towards mirror 1, bounce towards mirror 2, bounce back to the clock. You do it once from clock - mirror1 - mirror2 - clock then you do clock - mirror2 - mirror1 - clock. Then you compare the two, the time to go from clock to mirror is the same for both but the mirror1 to mirror2 is inversed in each essentially allowing you to compare the time it takes to go from mirror 1 to mirror 2 and the time it takes to go from mirror 2 to mirror 1. Edit: that wouldn't allow us to calculate the true speed of light since for all I know the acceleration probably is not instantaneous but it would allow us to see if light has different speed based on the direction its going towards

Why can't you send light from A to B, and when B is hit, send a signal back to A with something you perfectly know the speed (by wire, soundwave, ...)? You then substract the known time (B to A) from the total, and you get the one direction time. I don't get where the problem is...?

What about this? Combine the mirror experiment with a high speed camera. I will see the laser beam going from left to right and back (so only on the x axis, measuring like the baseball). If we measure the time until the light is back on the left, we don't know if the speed was equal in both directions. If we see the light via deflection in the high speed camera, this might cause the uncertainty (so it would be the fault of our y axis). But since the direction towards the camera does not change, if the light appears in the same speed from left to right as in the opposite direction, we are least know that the speed is symmetrical on the x axis.

What if you sent an astronaut into space with the order to send a signal back to mission control when he reaches 1 light minute away from Earth? You should be able to predict when he will reach 1 light minute away, you should be able to figure out if light is traveling faster or slower in one direction, as you should be able to accurately predict when the message should get to you. So let's say the astronaut is expected to get to 1 light minute away at 11:59 as predicted by his motion after the engines were shut off. Should light travel instantly, you would get the signal from him at 11:59, if it were c, at 12:00, 12:01 if c/2, and anything in between. I might be stupid though, but this does seem like a sound way to figure this out since you're only getting the signal from him based on his surroundings, not you sending him a message and getting the two-way problem.

How would a non uniform speed of light effect things like interference of two waves of light and other wave like behaviour of light? As i understand it we could infer if a forward moving wave had the same wave length as a backward moving wave by seeing if they can destructively interfere. And we could check if a forward moving wave had the same frequency (and due thus the same energy) as a backward moving wave by seeing if they can excite a particular atom or get absorbed by a material with a particular bandgap. And then we could get c from the combination of wavelength and frequency. I wonder if these things would still work with a non uniform speed of light though likely our understanding of the wave mechanics of light would also need to be be adjusted in case of a non uniform speed.

As someone who has got here by accident and whose main language is not english: why can't you just use the camera the camera that shoots 1 trillion frames per second (as shown in the 9min00sec) and send the light to a mirror to see if the light behaves differently it bounces back to the direction it came from?

I tried something like this twice in my life. The lest time, a couple of months ago, it was in a big cave in a mountain. There was no sound whatsoever. It was pretty amazing to hear every tiny noise you make. Moving your head, your clothes, breathing etc... I heard a lot of noise in my ear, not due to the environnement. Just parasite noise, like the girl was saying, probably the blood in my ears. It got quite uncomfortable after just 2-3 mins. Like a low pitch "hummmmm" that got slowly lower and lower. After like 15 minutes it was pretty much all I could focus on. Like if a big turbine was running, but just in my head. I could have done one hour I think but absolutely couldn't have worked in there as he said in the video.

This is entirely flawed. It's not luck the hockey player was born in January when his parents had sex 9 months earlier.. same goes for people born in prosperous countries. It's not chance or luck, it's an accumulation of decisions made. "Luck" doesn't exist. You're supposed to be smart yet you're talking about something mythical. Even in a sition where a deck of cards is shuffled & a person pulls an Ace out of the middle of the deck. That isn't luck, it's a consequence of how the cards were shuffled. Magicians use this to their advantage & make you think things are based on chanve/luck.

You can use two light sources in space light second away from one another and have simple logic to activate each light: when you see the other light flash, flash yourself. And then observe from another point in space that is in the same distance from each source of flashing light and log when each light flashes. Then repeat experiment multiple times when your position changes but distance from flashing light sources remains. If the light moves in different speed in different directions then you covered enough directions to notice it, no?

The point is from sending the message till the Mars received it we can measure the delay and then we can focus on which signal is faster (in my opinion I think the bigger equipment the fast response just like the size of the sun, so when he sending from mars is differently slow!!!) sorry bad english still learning.

You have to redirect it's biggest mass to prevent from clamping back together, if that means a dozen of boosters then i think should be able to do that. In theory this should suck the other leftover asteroid with it and hopefully safe the Earth.. :P
