When will people be able to leave the solar system, is the speed of light really the fastest?

I don't know if the landlord understands this, but I've said it in relatively simple words:

So far, with the existing scientific and technological forces can not fly out of the solar system, the following factors are considered: human behavior in spacecraft, flying in a sealed spacecraft for a long time, human beings will produce calcium loss, mental state imbalance (refers to staying in a confined space for a long time, human beings will feel lonely, thus producing psychological problems) and atrophy of leg muscles and other physiological conditions.

At present, the speed of light is the fastest, but the speed of light used by humans is only theoretical, because when the speed reaches or approaches the speed of light, the mass of the object will rise in a straight line with the increase of speed, and when the speed is infinitely close to the speed of light, the mass tends to be infinite, requiring an infinite amount of energy. In other words, if human beings move close to the speed of light or at the speed of light, human beings themselves will "increase", and in the end, they will be crushed

Theoretically speaking, beyond the speed of light, you can carry out the real sense of "crossing", however, at present, this is impossible, because according to the current technology, matter is impossible to exceed the speed of light, how to exceed the speed of light will be crushed by its own "increment" to ......

1. People can't yet, but Voyager is almost close to the edge of the solar system!

2. Yes, and the speed of light is constant. According to Albert Einstein's Theory of Relativity, if an object with mass reaches the speed of light, the mass will become extremely large. Also according to Einstein's Theory of Relativity and other laws of inertia, the greater the mass, the greater the inertia.

The greater the inertia, the more difficult it is for an object to change its motion and the harder it is to accelerate!

The first question, probably decades later. The second question is not necessarily. There are many theories that it is possible to compress space-time through wormholes, or with dark energy, beyond the speed of light.

Problem 1: If you don't think about returning, you can go out now.

Question 2: The speed of light is the fastest, see The Theory of Relativity for details.

How long does it take to fly out of the solar system and the Milky Way at the speed of light?

1.The radius of the Taichan Lusun Yang system is about 6 billion kilometers, and it takes about 6 hours to fly out at the speed of light.

2.The position of the Sun is 2 3 places from the center of the Milky Way, and it takes about 2314800000 years to fly out of the Milky Way at the speed of light.

3.The fastest speed of human beings, (taking rockets as an example, the fastest rockets can reach kilometers per second).It takes about 13 hours to fly out of the Earth-Moon system. Not to mention the solar system and the Milky Way. It's definitely an astronomical amount that you don't want to do.

How long does it take to fly out of the solar system and the Milky Way at the speed of light?

The radius of the solar system is about 6 billion kilometers, and it takes about 6 hours to fly out at the speed of light. The position of the Sun is about 1 3 places from the center of the Milky Way, and the diameter of the Milky Way is about 900 million light-years, and it takes about 30,000 years to fly out of the Milky Way at the speed of light.

If an airplane is moving at the speed of light, can it fly out of the solar system?

That's definitely possible, but in fact the speed of light is an upper limit that cannot be reached, and the derivation of the theory of relativity even says that if the speed of light is reached, you can go back in time. Secondly, you don't need to reach the speed of light to leave the solar system, as long as you reach the second cosmic velocity.

How far is it from Earth to fly 30% of the speed of light towards the Milky Way for a hundred years? Flew out of the solar system?

Thirty light years, it is early to leave the solar system, and the solar system will only travel for dozens of minutes. The nearest Proxima Centauri light-year.

The Earth-Moon is 380,000 kilometers away and can be reached at the speed of light in less than three seconds. The Earth is 100 million kilometers from the Sun and the speed of light takes eight minutes.

Solar system. If Neptune is used as the boundary of the solar system, the diameter of the solar system is 60 astronomical units, about 9 billion kilometers. If the orbit of the comet (Oort Nebula) is taken into account, the diameter of the solar system can range from 6 to 120,000 astronomical units.

That is, trillions of kilometers, about light years.

Galaxy. The position of the Sun is about one-third of the way around the center of the Milky Way. The diameter of the Milky Way is about 100,000 light-years, (the closest point from Earth to the edge of the Milky Way is about 10,000 light-years, and the farthest point is 10,000 light-years). It would take about 30,000 years to fly out of the Milky Way at the speed of light.

Calculate the route and take the most time-saving route, and you should be able to walk it all over in one day.

The speed of light is the fastest known in nature, 300,000 kilometers per second, so from the Earth to the Moon.

It only takes more than a second, and the earth to the sun only takes more than eight minutes, the longest planet orbit in the solar system is Neptune, about 4.5 billion kilometers, but this is not the boundary of the solar system, because there is a Kuiper belt outside the orbit, about 1 light year away from the sun, this station will take you to take a look.

Many people wonder how big the universe is and how edge it is? But this problem cannot be better explained, and the size of the solar system is difficult to define. The farthest probe that can be launched is Voyager 1, which is about 21 billion kilometers away from Earth.

The speed of light is about 300,000 kilometers per second in the universe.

According to calculations, it only takes more than a second to travel from Earth to the Moon. And it only takes more than eight minutes from the earth to the sun.

It is not a simple question to answer the question of how long it takes for light to fly out of the solar system, because it is necessary to understand how big the solar system really is.

How big is the solar system

The solar system you see on the Internet is the orbit of only a few planets, and the largest of the eight planets is Neptune, which is about 4.5 billion kilometers, but this is not the edge of the solar system. There are a lot of stones, ice cubes, etc., that revolve around the sun.

Outside the planet's orbit there is the Kuiper Belt, which is about 50 to 500 astronomical units away from the Sun and has always orbited the Sun. Beyond the Kuiper Belt is the Oort Cloud, which is even more extensive, and can even successfully extend to about 1 light-year from the Sun, which is thought to be part of the solar system.

If this is calculated, the radius of the solar system can reach about one light-year, and it will take about a year for light to travel from the Earth to the solar system.

The universe is vast and huge, and just looking at the scope of the solar system is quite terrifying, not to mention that the solar system is only a tiny part of the universe.

It is not the fastest, according to the current human knowledge, it has been discovered that it is faster than the speed of light, that is, the speed of the expansion of the universe. Speed plays an important role in the development of human civilizationTo a certain extent, speed is inseparable from the development of human civilization. The rapid development of human transportation and equipment has promoted the rapid development of human civilization.

Speed is very important to human beings, not only on Earth, but also in the universe. The means of transportation used by people on the planet require speed, and the absence of speed will limit the range of human travel; The computers or technology devices that people use also need speed, and without fast connections and running speeds, it is difficult to overcome scientific research difficulties, let alone meet people's daily needs.

Even looking at the universe is also inseparable from speed, and the rapid development of the country's aerospace industry allows astronauts to leave the earth to live and work on the space station, which is also inseparable from speed. You must know that if human beings want to leave the earth and go to the space station, they need to exceed the second cosmic speed. The second cosmic velocity refers to the lowest speed that can break away from the gravitational pull of the earth, which is about 11.2 kilometers per second.

When it comes to the speed of light, everyone may have heard of it, according to the calculations and analysis of many scientists, the speed of light is the fastest speed, which cannot be reached by humans or any object with mass. The great scientist Albert Einstein pointed out that the mass of any object increases as its velocity increases during acceleration. Simply put, once an object reaches the speed of light, its mass is theoretically infinite.

It is precisely in this way that the maximum speed that can be attained, whether it is a human being or any object with mass, can only be infinitely close to the speed of light, but cannot really achieve the speed of light.

The universe is considered to be a stable and eternal state, and even Albert Einstein believed that the universe is stable. However, with the rapid development of technology, scientist Hubble proved that the universe is expanding. His proof not only broke the common understanding of the universe in the past, but also discovered another speed faster than the speed of light, that is, the speed of expansion of the universe.

According to Hubble's research data, the cosmic mill is expanding far faster than the fastest speed of light. And the expansion rate of the universe has been accelerating since the beginning of the universe. Now scientists speculate that when the universe expands, it will go through a burst stage, which simply means that in a short period of time, the space can expand many times.

In this process, the extra space in the universe is more than the speed of light to move by one second every second. From this point of view, although the speed of light is the fastest speed in the universe, the speed of light is still reduced to a "turtle speed" in the face of the expansion speed of the universe.

Now you know! The speed of light is not the fastest, and there is a speed faster than the speed of light, which is the expansion of the universe. It's just that the acceleration of the expansion of the universe is not a good thing for mankind, and the galaxies outside the expanding bank system will continue to move away, so that humans can hardly leave the galaxy anymore.

It has reached a speed of 300,000 kilometers per second, and it cannot be captured with the naked eye at all, and can only be captured by specific instruments. This is uncertain, after all, our scientific recognition of the attack is limited now, and there are still many unsolved mysteries in the future, so there is still a faster speed than the speed of light.

The speed of the Silver Core of Light is calculated using the unit of light years, and it is currently impossible for humans to properly budget this fighting speed. So far, there is no faster speed in the universe than the speed of light.

It must be captured with professional instruments, and it cannot be seen by the naked eye at all. It should exist, after all, there are still many unsolved mysteries in the universe.
