Technically, matter is not everywhere, but that is besides the point for the issue at hand.
The more important issue is that inert-gas/CO2 is in fact used in winemaking to create a blanket above the wine. You only want to replace the gas space with your gas of choice leaving little to no room for oxygen. That way as the wine releases its own CO2 the airlock it will either release CO2 or inert gas from the gas space while simultaneously replenishing the gas space with CO2 from the wine.
One needs to take care as to not force excess CO2/inert-gas into suspension by over-pressurization of the gas space. Inert gas requires a higher pressure than CO2 to get forced into suspension with the wine, so naturally Argon is a more attractive gas than CO2.
Yes it is. Air is matter, water is matter. Its everywhere. Yes it is the whole point. You cant dispalce mater with out replacing it with mater, not on this earth. look we can argue this all night. Im done. I will end it with "Its my theory and Im sticking to it" Im done with this tread
e=MC^2 Matter can be converted between mass and energy fluidly. It happens all the time when gamma rays get turned into electrons or when positrons and electrons annihilate each other.
But, that is still irrelevant. Matter can be destroyed, converted and moved with nothing to replace it. Consider a coke, you let the gas out, gas did not just rush back in and replace the gas inside of the coke did it? Thus, the coke lost matter and mass but the outside air gained matter and mass nothing came in to replace it. If you want more details try looking up things such as control volumes.
All true, but probably a little too technical to be relevant to what we are doing here. Let's move on, please...

I do not think it in itself is a bad idea. Many commercial wineries use inert gas to create a safety cloud over wine to help mitigate oxidation issues. This below article describes its use..

I believe one thing you want to watch out for is managing to get CO2 into suspension with the wine. Ie, a protective blanket and not actually forcing it into suspension with the wine by over pressurizing/ concentrating the CO2.... But read the article for more details.... One thing that might be possible is using a keg to protect the wine with CO2 over the long term and then force degassing it when aging is complete.. However, I might be concerned about forming carboxylic acid from the CO2.
Vacumepumpman,
I remember you filling me in on this Idea. I thought it the only true viable alternative to topping off. You really need to market this idea..
OK,
Folks, I kept quite on this topic. No doubt that some of you may have though that I was sick or something as I have been very vocal about this issue. I will just breifly state my case for the sake of those that might no know me...
It its this: Home winemakers should NEVER use "gas purging" as a replacement for topping off.
1) As others may have said, Air will not ever be completly purged when adding either CO2 or a nobel gas. You need to consider density. Too often people think that the gas provids a protective blanket, but is simply does not. The nobel gas will mix with air and only serve to reduce the amount of air contact.
2) Some professional wineries may use gas, but if you notice, the tanks the wine is storred in has a perfect hermetic seal. This means that the tanks they use do not "breath" due to thermal and atmospheric expansion and contraction. In the case of a carboy that has a fermentation trap, like most home winemakers, this breathing will simply expell the gas in favor of outside air.
3) Considering the above two points, gas gives a winemaker a false sense of security. I know many that have used gas only to be shocked that their batch of wine has oxidized.
4) Finally, lets face it, gas is expensive. When you think of the price of a tank, regulators, etc, It would have been far wiser to simply top the wine up with wine or switch to a smaller sized carboy.
OK, I am off the soap box now.
