This is fundamentally not true.
Light is made of electromagnetic waves. If you can control the timing of those waves precisely enough, you can add another light with the opposite phase (an inverted wave) that will cancel out the other light.
This is what happens in the famous “double slit experiment”. It’s also the same principal as noise cancelling headphones albeit with sound pressure waves instead of EM waves.
Scientists have actually cooled atoms very close to absolute zero by shining a laser at them
I’m curious how that could possibly be the case…
You said in another comment that you were both making $45k. According to this table from the IRS you would each be paying $3,743 as single filers and $7,483 filling jointly. That adds up to a $3 savings when you get married. Not too mention a $6k difference is 80% of the total taxes owed so it would be wild to see that big of a variation caused by filling jointly.
Perhaps there was some tax break or credit you got when you were single that you lost when you got married? In that case, couldn’t you just file your taxes separately if there really was a significant difference from filing jointly?
