I think that Clueless was very deep. I think it was deep in the way that it was very light. I think lightness has to come from a very deep place if it's true lightness. — Alicia Silverstone

comment Why do we use microwaves in microwave oven?
@JohnRennie: I never said it was obvious. I said the OP is failing to perform any research, or to read the material presented to him.

comment Why do we use microwaves in microwave oven?
[..] quoted on the Q&A John linked you to, along with: "The frequency of 2.45 GHz is chosen because it falls in one of the bands not reserved for communication purposes. According to Wikipedia, the next available band would be at 5.8 GHz. A powerful magnetron working at this frequency is feasible but way too expensive for a household appliance". It seems you didn't bother to read it. :(

comment Why do we use microwaves in microwave oven?
@Bhavesh: What prevented you from performing basic research? Wikipedia says "The microwave frequencies used in microwave ovens are chosen based on regulatory and cost constraints" and "[higher frequencies] are not used for microwave cooking because of the very high cost of power generation at these frequencies", and this was [..]

comment Is it possible to watch the same distant star's supernova event twice?
This is clearly the answer. From the source you link: "One bonus is that, given the peculiar nature of gravitational lensing, astronomers can tune in for a supernova replay within the next five years. This is because light can take various paths around and through a gravitational lens, arriving at Earth at different times. Computer modeling of this lensing cluster shows that the researchers missed opportunities to see the exploding star 50 years ago and again 20 years ago, but images of the explosion will likely repeat again in a few years."

comment Zero velocity, zero acceleration?
"Infinite"? Are you sure? You are apparently conflating undefined values (at limits) with infinity, especially in the case of square rooting a negative value (presumably you're disallowing complex numbers): the result is non-existent, not infinite.

comment Why is the nucleus so small and why is the atom 99.999% empty space?
You might as well ask why most of the solar system is "empty space".

What air is "going through" anything when the rocket is just about to launch???

comment What do units like joule * seconds imply?
Man-hours is a great example that should help the concept to become intuitive.
