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.

Technically speaking, Hawking radiation has nothing to do with virtual particles. It has do with the oscillations we talked about earlier, and how they appear differently to different people near and far from the black hole. I have been hoping to write an article on this too, but for now lets keep it at this level.
When you leave school or university and start to look for a job you may worry that your lack of experience will impact your chances of landing a position. Because you are young, employers are looking to see if you have the right attitude and character to fit into their company. They…
Yes, oscillating fields correspond to particles, but these oscillations (and thus the corresponding particles) don’t exist. They are an invention to simplify a rather complex (and real) oscillation. They do not “exist” at all, even for very short intervals of time.
