<human>: We start with this analogy (or is it a simile?):

The earth and its atmosphere are like a fishbowl and its water. The atmosphere and the water have a volume and are contained within certain bounds. Each can be pressurized, but eventually they cannot be pressurized further.

Now, imagine this fish bowl filled to the top, almost pouring over. This is basically how I envision our atmosphere. It currently fills up all the atmosphere-available (I made that term up) space around the earth.

If one were to drop a few pebbles into the fish tank, the water would pour over the top. The pebbles had displaced the water and causes it to flow outside it's bounds.

Similarly, every time a lightbulb is manufactured on earth, atmosphere must be displaced. A lightbulb is a vacuum so the atmosphere can no longer occupy that space, just as the water could no longer occupy the space that the pebbles took up.

So too the point:

Can you succinctly summarize the text in 1-3 sentences?
<bot>: If we create enough lightbulbs on earth, could they potentially displace enough of our atmosphere to cause it (the atmosphere) to "burst"?
