I wouldn’t say its a useful way, but if you think about it, everything is vaccum if you zoom enough. Also absorption can mean different things though so keep that aside and think of it as some interaction going on which in effect slows it down.

Now i looked up on youtube and this is what i meant (timestamp included). I was looking for 3b1b explaination but this one works too. It’s arguable if we can call it absorption or not, and what I said before might be ambiguous. But this guy explains it well
