Atomic clocks are routinely used to measure the time difference between things on the surface of earth and things in orbit. The difference of the flow of time needs to be calibrated or else things like GPS wouldn't work right.

If communication were instant, how it would work would I guess depend on what you were using, since that isn't supposed to be possible.

Causality is the reason for there being different nows since if causality existed irrespective of time then things outside of now, from the perspective of an observer, could causes changes too far away to have actually been caused by the observer if, say, information could propagate faster than light. The reason light speed is what it is is because light speed in a vacuum is the speed of causality.

Your definition doesn't make sense as the period where the causes can be manipulated since, for example, my observation of the light from a distant galaxy is completely unaffected by anything happening in my now since the "now" of the galaxy I'm observing occured billions of years ago from my now. Now is entirely relative. The only way I can see the now of the galaxy I'm looking at would be to go there, and by then the now I want to be part of would have passed.

So, what I described it the opposite of that assertion. No one has to be around to observe difference in time, it is inherent to the fabric of reality.

Also, if a tree falls in the woods and there is no one to hear it, it still makes a sound as sound is the propagation of a fluid compression wave, which occurs regardless of an observer. What it doesn't make is a noise, since noise is the conscious experience constructed by the brain using the stimulus of sound.

The flow of time is relative, so time is flowing at different rates at different places depending on the curvature of the universe in respective locations and on relative velocity. Only when you get into the same gravity well in the same place can two objects be considered to be more or less at the same time. As soon as they leave the same gravity well or travel at different relative velocities, they are technically now in different times until they meet up again. That said, every single molecule, atom, subatomic particle is technically running at slightly different times even within the same object. Space and time are, under general relativity, considered inextricably linked, so can be thought of as the same thing. Changing space changes time, so being in even a slightly different spaces means you are in a slightly different timr. This is why the cosmic microwave background radiation is used as a universal resting position to make some sort of standard time.

The EPA literal purpose is to find evidence of environmental damage. They are trying to force the company to pay for and perform the testing, but the EPA is also doing testing now. It has nothing to do with conspiracy nonsense of them purposefully not wanting to find contamination.

Biochemical feedback systems mean that basically no part of your biochemistry is static on or off, but constantly in flux. The chaotic interactions of these feedback loops mean you'll have surges and ebbs in just about every process, including body temperatures during infections.

Almost like that's exactly what I said, that diesel ranges include molecules that are also in fuel oil but that fuel oil has a higher minimum, meaning fuel oil, on average, would be expected to have longer carbon molecules. Fucking reading comprehension. Get some.

It is produced from the fractional distillation of crude oil between 200 and 350 °C (392 and 662 °F) at atmospheric pressure, resulting in a mixture of carbon chains that typically contain between 9 and 25 carbon atoms per molecule.

Heating oil consists of a mixture of petroleum-derived hydrocarbons in the 14- to 20-carbon atom range that condense between 250 and 350 °C (482 and 662 °F) during oil refining.

Umm feel stupid yet?

Not exactly. While diesel fuel can contain the same length carbon chains as it found in heating oil, diesel has a range that includes much lower carbon chains than the shortest chains in heating oil. So, generally speaking, heating oil will tend to have more long chain carbon molecules than diesel fuel.

I just didn't know how to respond to someone flat posting the textual details of the law with zero context. Saying "ok" was a lowkey hint that posting something like that without any context doesn't really add to the conversation. Thank you for clarifying your position.
