What would happen if time were the same everywhere on earth?

Answer 1

If time were the same everywhere on Earth, there would be a number of significant changes.

Businesses would have to adjust their hours. Currently, businesses in different time zones have different hours of operation. If time were the same everywhere, businesses would have to choose a single set of hours that would work for everyone. This could be difficult, as it would mean that businesses in some parts of the world would have to operate during hours that are not traditionally considered "business hours."
People's sleep schedules would be disrupted. Currently, people's sleep schedules are based on the time of day in their local time zone. If time were the same everywhere, people's sleep schedules would be all over the place. For example, someone who lives in New York City would be going to bed and waking up at the same time as someone who lives in London. This could be very disruptive for people's sleep patterns.
Social interactions would be more difficult. Currently, people can socialize with people in other time zones by scheduling calls or video chats during times that are convenient for both parties. If time were the same everywhere, this would be much more difficult. For example, if someone in New York City wanted to socialize with someone in London, they would have to call or video chat during the middle of the night. This would be very inconvenient for both parties.
The way we measure time would have to change. Currently, we measure time using time zones. If time were the same everywhere, we would need to find a new way to measure time. This could be difficult, as it would require us to come up with a new system that is universally accepted.

Overall, if time were the same everywhere on Earth, it would have a significant impact on our lives. It would disrupt our businesses, our sleep schedules, our social interactions, and the way we measure time. It is unlikely that we would ever adopt a system where time is the same everywhere, but it is an interesting thought experiment to consider.

Answer 2

Well, if time was the same everywhere on Earth, that would mean that the Earth doesn't rotate, therefore in certain places it would be Daytime all the day and Nighttime all the time as well. Also, climates would be screwed up to the point where it would be mainly desert and tundra. There probably wouldn't be any life on Earth.

Answer 3

Why don't you ask what would happen if the sky were plaid, while you're at it?

Basically, this is not something that could possibly occur, so wondering "what would happen if" is rather pointless. To the extent that it even makes sense to wonder about this, the results would differ depending on what this "same" climate was.

I was going to say that the lack of temperature differentials would likely mean there was no wind and that would impact rainfall, in the sense that water vapor would move by diffusion alone so that only over or very near the oceans would there be any rainfall (and over large lakes as well, though how these would have formed in the first place is an open question), but that just points up how impossible it would be for there to be the same climate everywhere.
