The mysteries of the universe make science

The universe is always hidden with secrets that space science has not yet solved. Some of these mysteries have been discovered by humans such as planets, stars, and Earth attraction . But there are still many mysteries about the universe that hurt astrophysicists: inside the black hole nothing, dark matter, the end of the universe .

Here are a few tricky questions related to the universe that people are still"brainstorming"to find the final answer.

1. What is the universe made of?

Scientific research announcements about the solar system, the Milky Way make many people believe in human understanding of the vast vast universe. But there is a surprising fact that we have only found about 5% of the components that make up the mysterious space outside the Earth.

In fact, all the cosmic components that people are aware of are 'bright' forms of matter. They include elements in the periodic table, which assemble smaller molecules, atoms and particles that make up them such as protons, electrons, neutrons . All of which are components of the Earth. but we only account for 1/20 of what constitutes the universe.

The question is what is the remaining 95% of the universe? People know their existence but cannot look or study specifically, directly by these invisible components. They are 'dark ' matter - accounting for 25% of the universe and 'dark' energy - accounting for 70% of the universe.

Specifically, 'dark' matter does not glow and is considered to be around galaxies and galaxy clusters. Experts call them 'invisible cloaks'. People only know their existence because they measure the mass and gravity they impact on 'bright' matter.

'Dark' energy is even more mysterious. They are thought to be the kind of energy that exists in the universe, capable of accelerating galaxies closer together or farther apart. However, an accurate theory of this issue has yet to come and the scientific community is still "clinging" to this question.

2. Are people lonely in the universe?

Since cosmological science was born and developed, a question is always permanent for human society, is there anyone outside the Earth? People launched spacecraft, explored many planets to find other life, but so far, the question has not been answered yet.

How many Earths in this universe?

Many hypotheses are made today to guide research. Typical is the multiverse theory , derived from the term William James of the same name in 1895. Accordingly, it is thought that there are many universes parallel to the space in which we live.

Model of multiverse theory

From this theory, modern research today mostly assumes that people have "neighbors " in other planets and universes. In 2011, in order to correctly answer the question above, some US scientists used the most advanced technology to broadcast radio out into space .

This wave is transmitted if detected by aliens , they will send back the waves to Earth. According to them, with this method, within 20 years, we can determine whether there exist alien civilizations.

Can people be alone in this universe?

3. What is inside the black hole?

Black holes are the remaining space of stars that self-destruct under their own gravity . It is dubbed the god of the universe, can ' devour ' all planets, celestial bodies and light if unfortunately lies on its horizon.

So what's inside the universe's black hole is no one can get the answer. We only know that the black hole has a huge attraction and any planet that gets sucked into the black hole will disappear without a trace.

Many hypotheses are proposed to explain the phenomenon. The latest research in 2013 published in New Scientist magazine said that black holes do not destroy planets, the bodies that it absorbs.

Is the black hole the gateway to the other universes?

The black hole is actually a space gate , giving everything that is entrenched into another cosmic universe where we live. Also, it is likely that the black hole could be a research focal point for the dream of traveling through space and human time.

4. How to take advantage of more energy from the Sun?

Humans are facing a constant energy crisis as fossil fuel sources gradually run out. The search for alternative energy sources is still being studied and solar energy is always considered a great end.

However, there is the fact that solar energy is not currently being used properly. Although the development of science and technology, the efficiency of solar cells is not really high, only about 16%. On the other hand, due to natural conditions, not every land on Earth has the ability to use solar energy well.

Current solar battery performance is not really high

Another question is whether people possess this abundant and abundant energy to solve the predicament on Earth? And now, scientists are still working hard to find solutions to that difficult problem.

The possibility of survival on Mars

Life is likely to have existed on Mars and may even exist today. Mars used to have large oceans. Scientists found evidence that liquid water still flows periodically on the surface of Mars. Many countries are planning to bring explorers to Mars to find out.

The origin of high energy cosmic rays

Cosmic rays are high-speed particles that fly in space and sometimes hit Earth. But scientists have not found their origin. " The lowest energy cosmic rays come from the Sun in the form of charged particles called solar winds. However, it is more difficult to identify sources of high-energy cosmic rays because they affect the word. "The field in interstellar space ", astrophysicists at the European Nuclear Research Organization (CERN), said.

Fast radio pulse generator (FRB)

A fast radio wave pulse is an outbreak that only lasts one millisecond of radio waves in space. Like cosmic rays, scientists don't know where to produce fast radio waves. One theory is that they have the same origin. But other opinions claim RFB comes from events that are hard to repeat.

Why is there more matter than antimatter?

When a matter particle and an antimatter particle collide, they cancel each other out. If the number of matter particles and antimatter are equal, the universe will not exist. According to scientific theory, the Big Bang explosion produces two equal types of particles. But for some reason, this explosion created more particulate matter. According to astrophysicists at CERN, one of the greatest challenges of physics is finding out what happens to antimatter particles.

How will the universe end?

Astronomers estimate the Sun will destroy Earth after about 6 billion years . Some hypotheses about the end of the universe are given. According to thermodynamics, the universe can be destroyed when all matter in the universe has the same temperature. That means all stars will die and all matter will dissipate. Another idea is that an event contrary to Big Bang is Big Crunch. If the universe continues to expand, the gravitational force will eventually become too large, leading to all things shrink. The whole universe will become a solid mass and the universe will end completely.
