@FuglyDuck wait a second. A flight from India to the USA takes about 24 hours. It’s basically the difference of a day. But if you look at the local clocks before boarding the flight and after alighting, there may not be any shift in time, although there’s been immense change in space.

Following a similar example, it would be interesting to note the differences after one has returned back after a voyage into space.

@Astronut the drive of a wife ??

@ChaoticNeutralCzech @Zwuzelmaus here it gets confusing.

@ChaoticNeutralCzech @Zwuzelmaus geographically speaking, the point where the prime meridian and the equator meets, that’s point zero of the earth ??

@ChaoticNeutralCzech wait a moment. Suppose l’m taking a bath in the river. The more I move horizontally, the temperature of the water changes. The deeper (vertically) l move, pressure starts changing.

Is that what you meant ??

@melsaskca l’m talking about one singular point.

@sylver_dragon thanks for that wonderful answer :)))

@Astronut do you seriously consider yourself un average ??

@melsaskca well, l never ask for anyone else.

@TheRagingGeek thank you for sharing your perspective.

@ChaoticNeutralCzech honestly l’ve got no knowledge of graphs.

@Astronut and you’re an automaton ??

@Nester meaning of the second sentence ?

@Astronut an interesting perspective which I wouldn’t understand as l’ve got no such person in my life.

@ChaoticNeutralCzech don’t get it

@ChaoticNeutralCzech could it have been simpler ??

@FuglyDuck spacetime is an intriguing word, because time and space are entirely two different concepts… Having different measurement units…

Is there any particular unit for measuring spacetime ?

@Skullgrid what’s that ??

@Zwuzelmaus what’s point zero ?

@edgemaster72 according to your comment, existence itself ought to be meaningless…
