Night and Day, and Four Seasons
Our real
daily experience will really have to do with the universe and outer space. If
we think what is causing that deeply rooted in the structure of the universe
and the nature of the composition universe that is actually made up of tiny
particles, elementary particles. The first subject something granted is: night
and day. If we wake up in the morning we don't have to think that the sun would
go up, and later that day, sun would go down, and that's absolutely normal. We
take that for granted. We never question why that happens. But that really has
to do with the fact that we're actually sort of floating in outer space and, and
rotating around. So the many phenomenon’s’ we see today actually have some
background in what's going on in outer space.
The day is because the part of
the Earth receives light from the sun. But we know the Earth rotates, so only
the part of the Earth that's facing the sun is lit up and, and becomes a day. But
the other side is in the shadow of the Earth itself and that's the night. And
as the Earth rotates around, different part of the world gets shone by the
sunlight and that's how we think the sun rises and sets. In Ancient times
everybody believed Earth was flat with no space that surrounds us, and we are
actually at the center of the universe. That's
not the case as day and light was already in evidence that we are so hung in
empty space and we're receiving the light from the sun. There’s some end to it
and the sun rises from one end and then sets on the other end. We can point out
the fact that there are four seasons we experience in a yearly cycle. And that
has to do more with the fact that we revolves around the sun.
We know that the
Earth revolves around the sun once a year and the way we understand the seasons
is the fact that Earth rotating axis is actually not straight up but slightly
tilted. So, if we're living in the Northern Hemisphere pointed towards the sun
we will receive more sunlight. But as the Earth revolves around the sun, it's
always tilted. And if it comes to the winter, then we are tilted away from the
sun. So, that would get you receiving less sunlight. if we come back to spring,
again, it's sort of the we're getting the sunlight from sideways. It doesn't
matter which way it's tilted and then we eventually come back to the sun when
we receive more sunlight again. That determines the four seasons. So, this
understanding can be immediately proven just by looking at the variation
temperatures between northern
hemisphere and southern hemisphere which are opposite .
