The discussion revolves around a hypothetical scenario where the universe is scaled down to the size of a laptop, and the implications of moving a hand across this scaled universe in relation to the speed of light. Participants explore the concept of relative speed and the assumptions involved in such a thought experiment.
The conversation includes various interpretations of the original question, with some participants attempting to clarify the physics involved while others express confusion about the hypothetical scenario. There is no explicit consensus, but several points of view are being explored regarding the nature of speed and dimensionality.
Some participants note the lack of clarity in the original question and the assumptions made about being separate from the universe. There are references to the mathematical concepts that may not be fully understood by all participants, indicating a potential gap in knowledge regarding the physics involved.
That just makes no sense. "If the universe was the size of my laptop" then what time would it take light to pass over it? How long is a km in that scale? And are you not part of that universe? If so, you cannot move your hand over it. If not, your speed is not relevant to it.patricktaylor said:if the universe was the size of my laptop, and i moved my hand over my laptop from one end to the the other in let's say ... 1 second . relative too the universe my hand would have moved millions of times faster than the speed of light. Why is this? is speed relative to size?
patricktaylor said:the point of the question was to see if by me, hypotheticaly being larger than the universe and if you like .. separate from it. Would my finger break the light speed constant as it was passing over the laptop sized universe? even though the speed of my hand would seem slow to me
What is the size of your laptop? I'm guessing it is about 1 foot (or about 0.3 meters). So, "if the universe was the size of my laptop" means the same thing as "if the universe was about 1 foot in size".patricktaylor said:if the universe was the size of my laptop, and i moved my hand over my laptop from one end to the the other in let's say ... 1 second . relative too the universe my hand would have moved millions of times faster than the speed of light.

Since this is not only outside mainstream science, but contradictory to say something is two different sizes, this thread is now closed for discussion.ryanmichaelrey said:It's like having 2 dimensions in 1 universe. First dimension is your larger version, and the other dimension is the minimized universe (based on your statement). Based on the extent of my knowledge, the 2 dimension will have 2 different laws.
