    Mystery Origin
AI Thread Summary
The discussion centers on the concept of the universe originating from a singularity, a point of infinite density, inferred from redshift observations indicating the universe's expansion. As distant stars emit redshifted light, it suggests they are moving away, leading to the conclusion that the universe was smaller in the past. This reasoning implies that if the universe is expanding, it must have started from a very small state. The debate touches on the inadequacy of current physics to define the universe's size at such extreme scales, potentially smaller than the Planck length. Ultimately, questioning the size of the universe's origin is deemed irrelevant without advanced knowledge in string theory or particle astrophysics.

why the Universe was at a small point? Is this point like super small like.

Plank length

Or just any size smaller then Planck Length? To be undefinable.

Why couldn't the universe just all of a sudden be created right where it is, in all the same motions as everything is in.

Im sorry i don't understand want you point is.

The main reasoning behind the idea that the universe was once a small point is based on the redshift. The shifting of light toward the red end of the spectrum is taken by most coamologists to mean that the stars emitting this light are moving away from us. The more distant a star is, the more red-shifted its light; meaning that the more distant stars are moving away faster. This produces the image of a universe that is expanding. If the universe is exanding, then it is bigger today than it was yesterday. Therefore, it was smaller yesterday than it is today, and the day before yesterday it was smaller still.

If this line of reasoning is taken back far enough, we get to a point when the universe was very very small.
 
Till you get to a point where the universe ends up being so small that the physics we have is inadequate to explain it. Such a state is referred to as a singularity.

To actually question the scale of size is meaningless unless you are a string theorist or particle astrophysicist.
 

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...
