    Events Infinite
AI Thread Summary
The discussion centers on the nature of time and whether it is infinite or finite, specifically questioning if time existed before the Big Bang. Participants explore the implications of time being infinite, suggesting that even if time began with the Big Bang, there could still be an infinite number of past events. The analogy of points on a line segment illustrates the concept of non-countably infinite sets. Ultimately, the topic remains unresolved, highlighting the complexities of understanding time's existence. The conversation emphasizes the philosophical and mathematical aspects of infinity in relation to time.

Is time ever existent (infinite number of events in the past) or did it come into existence with the big bang (finite number of events in the past)?

Even if time came into existence with the big bang there would still be an infinite number of events in the past. How many points are on the line segment from 0 to 1? Not only is it an infinite number, but it is a non-countably infinite number.
 

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
