How Far Can Humans Explore the Universe? These are 5 Science Answers
NASA astronauts prepare for training and inspection for mission EVA-50
Netgenz - Sains | Until now, humans have had a lot of technology that can open up our opportunities to explore the universe further. Technologies such as Voyager 1 and 2, the Space Station, the Hubble Telescope, and other space probes have reached a point where they can teach us something about the universe. However, it must be considered if only a piece can be obtained. With an almost limitless area, it seems impossible for humans to exploit the universe optimally. Our civilization is also still young when compared to the age of the universe which has reached almost 14 billion years. It's fascinating to discover how far humans can travel in the universe. Want to know the answer, right? Well, just read some of the following scientific discussions.
1. Until now, humans have only been able to reach the moon

Human determination and will to explore outer space have existed since time immemorial. It wasn't until April 12, 1961, that a Soviet cosmonaut named Yuri Alekseyevich Gagarin succeeded in traveling into space for the first time. At that time, he used the Vostok 1 vehicle and successfully traveled in Earth orbit for 108 minutes, as quoted by NASA. Then, on July 20, 1969, humans again instilled achievements by landing on the Moon for the first time. Then, NASA has often succeeded in sending astronauts back to the Moon. So far, only the Moon has been the most distant destination that humans can do directly. I don't know when, what is clear is Mars will be our next destination.

2. Voyager 1 and 2 are man-made means with the farthest exploration power
Voyager 1 has become the vehicle with the furthest cruising
Voyager 1 and 2 are unmanned vehicles released by NASA on September 5, 1977, and August 20, 1977. Today, they are working and for more than 44 years they have sent a lot of important data to humans. Yep, Voyager 1 is at a distance of 22 billion km. Meanwhile, Voyager 2 has reached 17 billion km from Earth. In other words, either Voyager 1 or 2 has reached interstellar space. That means, they are already in the outermost zone of the Solar System and this is the longest distance that can be reached by human-made means. Both facilities are equipped with plutonium batteries that have nuclear power that can be active for several decades. Chances are, Voyager 1 and 2 batteries will run out in 2035 in the future.
3. Mystical wormhole

What is the relationship between wormholes or wormholes with human exploitation in the universe? Researchers have and are studying this as a side of the laws of physics. According to the Space website, the wormhole theory was first proposed in 1916 by an Austrian physicist named Ludwig Flamm. At that time, Flamm knew that through Einstein's theory of relativity, a new idea about the transition of space and time could quickly be implemented. As we bend the paper and pierce it with a pencil, such as the condition of the dimensions of space and time in Flamm's shadow. If this is true, then humans can explore the universe as long as possible. Unfortunately, until now, wormholes have only been in theory.
4. Humans are really hard to exploit the universe

Despite all kinds of determinations and theories that humans have, we should apply reality. What is the purpose? This, it may take several hundred thousand or millions of years back for human civilization to be amazingly advanced. If it's like this, it's definitely easier for us to explore the universe with existing technology. Today, exploitation far beyond the solar system is still an impossibility.
As reported in IFL Science, humans may be able to explore the solar system in great ways in the future. However, there are various obstacles to be encountered, such as cosmic radiation, fuel, limited speed, and the idea of backup in case things don't go smoothly out there. Tracing the solar system takes a dozen to several decades.
Once again, get rid of the assumption that our means are like the big ship Star Track or Star Wars. No, that kind of thing only exists in movies and is impossible to implement in the real world today. What humans can do now--through space bodies--only concentrate on exploiting Mars, the most rational planet for humans to visit in the future.
5. What about the speed of the beam?

We know that light travels at a speed of 300 thousand km per second or equal to 1 billion km/hour. Meanwhile, the fastest space rocket or spacecraft made by humans only reaches 28 thousand km/hour, quoted by NASA. Humans have a limit to receiving pressure when they move. The faster it moves, the greater the guaranteed gravitational suppression (G-force).
All laws and theories in science agree that there is no object whose speed can pass through the light. In other words, only light travels at the highest speed in the universe. All objects that exist in a state of high speed must be crushed or destroyed, as well as humans. Then, don't forget the distance of the universe which reaches billions of light-years.
Nach, if light alone takes a few thousand, millions, to billions of years to travel in the universe, what else can man-made rockets have speeds far below that. Well, actually humans cannot explore the universe. It is possible that this determination can be carried out if our civilization is truly advanced as in some science fiction films. Thinking of traveling around the universe is a scientific delusion that some people may have thought of. However, we must also realize that it is still impossible to do and humans can only concentrate on Mars first.
