The truth is that many of us slip through life, fully adrift and unaware that we’re not really
Virtual particles are useful: they help make our math easier, they provide an intuitive way to imagine perturbation theory, they can be used to make new predictions and discover new physics. Yes, they are convenient and they are a lot of help, no doubt on that.
I bought the old clunker, a TP-Link Archer C7, in 2015. It was the Wirecutter pick at the time, which gave me license to tell my roommates that I was going to spend $100 on a router.
Hawking radiation is usually explained as the result when one pair of virtual particles are formed, and one of them enter the black hole, and the other escapes. Very intuitive and simple to understand right.
This is taken to be the primary existence of the virtual particles: since for arbitrarily small time scales, we cannot know the energy, the field is bustling with particles. dwrhtefd
If I were to sum this up: we cannot know for sure how much energy the field has for small values of time. This energy may be fluctuating from picosecond to picosecond, and there is no way we can accurately measure and predict the energy of any field.

While I do not deny the validity of this principle, there is no way that this is conclusive of virtual particles. What this says that in empty space, there is a small uncertainty for the amount of energy a field can have. That’s all.I’ve been obsessed with e-ink since buying my first Kindle, but the technology has largely been relegated to reading books, despite its potential for so much more. The 10.3-inch reMarkable 2 ($399) takes e-ink and shows off its…Just because virtual particles gave us a more intuitive understanding does not mean that is the whole picture. Hawking radiation is one of the cases in which a piece of math is taken too literally to simplify things.
Of course, maybe we will find more than these, but as of now, both theoretically and experimentally, these are the only particles that can exist. Unreal particles from the void? Only sci-fi or math.
