do you think?

Question

do you think up multiple scientific questions in a day? like how do scientists know that the universe is an endless expanse and if you go in the same direction you will never come across the same spot ever? it would make up so much more sense if i go there. what are some of your questions?

Answer 1

Some people have dreams about things that did not happen yet. Some people have a 'gift' for seeing the future.
My thing with this is: If somebody can see the future, does that mean that it already happened but we just did not reach that time yet? How does time work?

Answer 2

Newton assumed that space was an empty container of
things which is incorporeal, absolutely penetrable,
never influences anything, and was never affected by
any influence. Modern scientists found that his law of
gravity could not be applied to matter at quantum
mechanics level.

Ancient Greek and Roman philosophers thought that
universal space is filled by absolutely motionless
ether. Moving bodies were thought to encounter an
ethereal wind which resembles the real wind that
resists a running person. For them, space was immutable
and motionless; its attributes did not depend on
anything, even time; nor did they depend on material
bodies or motion. This is what Newton could not
comprehend.

The discovery of the electro-magnetic field, new laws
of quantum mechanics, and the general realization of
many scientists that field could not be reduced to a
state of pure mechanical environment revealed the flaws
in the conventional approach of science. It turned out
that matter could not be represented as a set of
separate, and strictly dissociated elements. The
particles of matter are indeed connected with one
another in integral systems by fields whose action is
transmitted at a finite speed that is limited by a
closed system.

The subject of dialectical materialism was proposed to
overcome the limitations of conventional science. It
acknowledges the unity of motion, space, time and
matter, which is expressed in the principles of various
forms of the structural organization of matter. The
levels of the organization are characterized by
specific motion, space and time represented by a
given body. In theory, dialectical materialism is meant
to provide both a general world view and a specific
method for the investigation of scientific problems.
It deals with the fabric of space with numerous
inter-connections.

Marx and Engels never wrote a comprehensive work on
dialectical materialism. Its central tenet was borrowed
from Hegelianism. It is called dialectical materialism
because its approach to the phenomena of nature, its
method of studying and apprehending them, is
'dialectical', while its interpretation of the
phenomena of nature, its conception of these phenomena,
its theory, is 'materialistic'.

Since the subject received favour in communist
countries, people of western countries dubbed it as
communist theory. But the subject gives many thoughts to
deep thinkers in science.

Answer 3

You should read a popular science book such as those of Stephen Hawking. I like to ask about the Universe but I am more concerned about the problems we have down here. About the Universe, it is not endless but it is expanding, how do they know?, Albert Einstein provided a tool, General Relativity!.

Answer 4

I think why electrons can move. ï¼¥lectrons can move like some wave but what is their energy provided for moving.
Ｗhy they can be thrown out from the atoms just because the atom is unstable. Ａnd what happens to electrons if they are under 0Ｋ?

Answer 5

why is scientists always trying to solve the problems in space when we have our own problems on earth to deal with
