a gogleplex years. it is a number with so many zeros that you wouldn't have enough space in the universe to write it all out
no way. because universe is so huge it has no end at all
Yes it is a possibility if it was true.
Pure white light then it starts over on the other side of the universe.
Everything in the universe. things on the other side of the universe are affected by earth's gravity, but so slight that it isn't recognizable.
FAR FAR too long
You would certainly sink - the Sun has no solid surface. You would fall out the other side ONLY if you managed to get through without friction, which is not likely to happen. You would also be converted to gas long before reaching the other side, due to the immense heat.
That would depend greatly on whether one is flying, driving, or walking.
You can set up a proportion and solve for the unknown side. Say that your rectangle has a short side that measures 4. The long side, unknown at this time, is x. The scale factor of the long side to the short side is 2/1 or 2:1. That would mean that the ratio of the actual side measurements, long side to short side, would be x/4. Set up a proportion where that ratio and the scale factor are equal to each other. Cross multiply and solve for x. x/4 = 2/1 x = 8 The long side of the rectangle would measure 8.
FAR FAR too long
About 100,000 years.
Try shaving the long side
There is nothing above below or in the side of the universe as it keeps expanding.
