Will the world become homogeneous in the future due to globalisation?

Yes, because too many people want a good image, e.g.. buying and wearing Nike, as it is good quality clothing and it is seen to be more expensive which gives them a good representation (they have enough money to buy the items). eventually everyone will start doing this, and this will make everybody look alike which will take away their individuality.

No the world won't extend or expand because Earth is Earth and you can not change planets even globalization. Maybe Earth might change in the future but it won't get bigger as i think because if it did Earth would get damaged and the inner core and outer core and the lava will probably make Earth go nova!
This is what i think and i hope this helped you! :)

The sun's parallax would be 180 degrees, greater than which you can't get.  so a. would be your anwser
