How do you mean?

Well I mean if there were. There's nobody near a black hole, but we could still imagine if there were somebody how time would flow relative to something else. If God is outside the universe, is it possible for there to be a universal clock?

Is it possible for the to be a universal clock that someone outside of the universe could time events with, and view the different ways that time travels in the universe?

When cosmic background radiation was created the time flow throughout the universe was pretty much the same everywhere, right? So if we made a clock based on that and called it a universal clock, then would the flow of time in the early universe be slower relative to the universal clock than...

When the universe was young, and everything was closer together, did the extra gravity cause time to run slower than it does now?

My wife and I think two different things, and I would like to see which of us is correct. I'm only somewhat knowledgeable of physics, so I may be wrong. We need an electric heater for a bedroom. My wife says we should be an energy star heater. But I'm saying that it doesn't matter which...

Correct me if I'm wrong, but doesn't accelerating an object at 5mph per second for 10 seconds take the same amount of energy as accelerating it at 10mph per second for 5 seconds? Either way the object would be going 50mph. So why does the latter get worse gas mileage in a car?
