The universe is boundless in space, and the universe is in time. What is the universe physically?

The universe is boundless in space (universe) and has no beginning and no end in time (universe).

Matter comes first, and spirit (consciousness) comes second.

These are materialist views.

Hehe, sometimes I think about this problem, and my head hurts.

Why can the Earth float in the universe?

When did it start?

In which space is the universe?

Hey, you'd better wait, wait for the faster-than-light spacecraft to be developed, and explore it yourself.

This question is really difficult, wait, wait, there will always be a result!

The question has been left on hold for more than 2,000 years, and the jury is still inconclusive.

In fact, I think it can be explained by infinity, time and space are also infinite, this is the infinity of the universe. Because we are changing every day, but we are just in it, but we don't know what he really is.

Time and space are infinite, so it is formed in the process of the operation of the universe, this time and space, then the universe is infinite, then time must also be infinite, this is the law of nature, there is no way to explain it.

Judging from the current level of science, time and space are endless, so time and space are also infinite, which is the so-called infinity of the universe.

The universe refers to space, the universe refers to time, and the universe is the general term for time, space, and empty matter.

a.That's right. b.Mistake.

Correct Answer: a

Universe; Reality is a spatial concept, natural and eternal, formless and endless, boundless. At first there was nothing, only infinite carrying capacity, and there was an invisible magic and a huge amount of dark energy that gave birth to the primordial matter of the universe. Everything inside is from scratch and has gone through an infinite process of development.

The primordial matter of the universe mainly consists of ordinary matter and dark matter. Among them, ordinary substances; That is, what we can see is a substance made up of "elementary particles". Dark matter; A substance that cannot be studied by electromagnetic observations, does not interact with electromagnetic forces, and can only be known through the action of gravity, at the elemental level, the earliest elements in the universe are hydrogen, helium, oxygen, carbon, neon, nitrogen, magnesium, silicon, iron, sulfur, lithium, beryllium, sodium, aluminum, potassium, calcium, etc.

and many unknown elements that cannot be detected under specific low-temperature environmental conditions. All the stars in the universe evolved from these basic material elements. The answer is "nothing", because only "nothing" can make the universe have the basis for infinite changes, and it is precisely because of this "nothing" that the universe can be boundless and all-encompassing.

Of course, this "nothingness" is not nothing, but a form of something that has structure but no three-dimensionality. Take gravity, for example. It's the existence of this kind of thing.

This kind of thing called "nothing" is the number "0" if it is expressed in mathematical form, although it is zero, but without it, mathematics is not a system. <>

The universe evolved from matter and energy, and there is nothing that is not matter. The evolution of matter starts from the most basic particles, and the evolution process follows the basic laws of conservation of energy and mass. Please be detailed****.

Through the microscopic evolution of elementary particles, an infinite model of the universe was gradually formed. It provides theoretical support for the universe and the origin of life. So far, the universe as we know it is made up of vast spaces, various celestial bodies, and diffuse matter, which is the umbrella term for all space, time, and matter.

According to the latest research, the diameter of the universe is more than 156 billion light-years, and the observable age of the universe is about 100 million years. <>

The basic materials that make up the universe are binary stars, star clusters, nebulae, satellites, dark matter, dark energy, infrared, and protons, and it is through these substances that the universe is very stable.

I think the basic matter that makes up the universe is organized matter, dark matter, elementary particles, dark energy, and planets. These are the basic substances that make up the universe.

Ordinary matter, dark matter, dark energy, the speed of light, galaxies, these are the basic substances of the universe, and the universe contains a lot of matter.

These basic substances are, dark energy, dark matter, ordinary matter, electromagnetic radiation, antimatter, and these substances make up the universe.

You should see that it is pitch black, even if the universe is limited, it is very large, and human beings do not know that they have stood at the edge of the universe and see a piece of darkness

If human beings stand at the edge of the universe, they may see nothingness, or they may see some cracks, after all, the edge of the universe may be anything, or some planets or void holes.

You may also be able to see a wider external space, and some unexpected things may occur.

Answer] Substance, molecule;

Answer analysis] Test question analysis: From a microscopic perspective, the universe is composed of matter, and matter is composed of molecules. Molecules are the smallest particles of matter that retain their original properties.

Test Center: This question tests the understanding of the universe from a microscopic perspective.

Comments: For such questions, students should grasp the understanding of the universe from a microscopic perspective. Matter is made up of molecules, molecules are made up of atoms, atoms are made up of nuclei and electrons, and nuclei are made up of protons and neutrons, which in turn are made up of smaller particles, Senqing quarks.

1) The universe is made up of matter, and matter is made up of molecules;

2) There are many forms of matter in the world, and the matter around us generally exists in three forms: solid, liquid and gaseous

So the answer is: matter; Molecule; Guxiang early collapse, round liquid state, gaseous state

1. The universe is made up of (matter), and matter is made up of (molecules and atoms) Pick. 2. The molecule is the smallest particle that retains (the original properties of the substance). The diameter is only a few hundredths of a meter, about (10-10 m).

"Nanometer" is a (length) unit guess number file, 1nm = (10-9)m.

The universe is a unity of space, time, matter, and energy, and is a synthesis of space and time. The universe as understood in general is a continuous system of space-time in which we exist, including all matter, energy, and events in between. 1 The Composition of the Universe The real existence of the universe shows that it must have its own organizational components and basic appearance, and in recent years, domestic scholars have used mathematical methods to put forward an expression that reflects the composition and fundamentals of the universe

The dimension of the dimension is based on the dimension of the object, which depicts the use of space.

The universe is boundless, and scientists believe that it exists within a monster, and every galaxy in the universe is a monster cell, just like the atoms in our human bodies.

3. The reason why the space and matter of the universe are infinite is also because the space of the universe is too huge, so it is beyond human cognition. In fact, for us, the reason why we want to call the space and matter in the cloud as infinite, is also because with the level of science and technology under human beings, it is impossible to measure the space and what matter in the universe, because of this, we can quantify an infinite finite space and matter as an infinite existence, which is beyond human cognition in a sense, so nature is defined as infinite.

Theoretically speaking, the space and matter of the universe are indeed limited, so matter will not be created and disappeared out of thin air, and space is also constant, but in a sense, there is a cognitive bias as an observer, so it is definitely impossible to space and matter.

Infinite. Because scientists have also conceived of a black hole in the universe that is the opposite of matter, and the energy source is constantly sending matter outward.

Infinite. Because the universe is infinite, so the space and matter in the universe are also infinite.

Surely it is limited. Nothing can be infinitely owned, and the earth will have that day.
