Are humans "prisoners" trapped in the galaxy?

The Milky Way galaxy is a giant spiral disk galaxy. At the same time, it is also the home in which we humans live.

Inside the Milky Way, there are about 200 to 400 billion stars like our Sun. This makes the Milky Way a huge galaxy, with a diameter of about 160,000 light years.

Our Sun is about 26,000 light-years away from the center of the Milky Way, which is at the edge of the galaxy, similar to a suburban area.

Whenever the Milky Way is mentioned, you will often see a comment in the comments section where someone will ask if the Milky Way is so big. According to our current level of technology, do we have the ability to fly out of the galaxy?

Today we will discuss the method of flying out of the galaxy. Analyze whether we humans will be able to fly out of the galaxy someday in the future or not. Or is the Milky Way a cage in which we are imprisoned, as everyone says?

If we look at the current level of human technology rationally, wanting to fly out of the galaxy is almost an impossible thing. The rockets we use now mainly rely on chemical fuel to generate power.

At present, the farthest place that humans have reached is only the moon, which is 380,000km away from our planet. It seems that

It seems that the Moon is very far from our Earth, but such a distance takes only a second to fly at the speed of light, which can reach 300,000 km per second.

Voyager 1, the probe that carried the greatest dream of mankind. One of the more advanced technologies it utilizes is the planetary gravitational slingshot effect acceleration.

Even with the use of such high-tech technology in the universe, so far it has only reached a distance of 22 billion kilometers from Earth.

According to such speed calculations, Voyager I want to fly out of the solar system will need nearly 20,000 years.

Because the diameter of our solar system is about a light-year distance, and the speed of Voyager 1 is now only 17km per second.

If we zoom out to see the entire galaxy, then it is not an easy thing to accomplish.

Having said that, one question may arise.

The diameter of the Milky Way is 160,000 light years, so will the probe fly vertically? The vertical distance must be much smaller.

Here to give you data, the thickness of the galaxy is at least 3000 light-years or so. If we calculate according to the speed of Voyager 1, it will take about 50 million years to fly out of such a thickness.

Because the speed of 17km per second for the thickness of 3000 light-years, is simply too insignificant.

Not to mention that such a speed from the fourth cosmic speed of the galaxy escape speed is still far from.

So trying to fly out of the galaxy is not an easy task, even if the ship has unlimited fuel available to us, but the human lifespan will also limit our flight to the farther depths of the universe.

In the previous topic, we mentioned about human life span, and according to modern biology, the maximum life span of humans is about 120 years.

For the long flight time, it is completely unable to reach the purpose of human beings. So life expectancy is also a key factor that prevents humans from flying to the universe.

Speaking of which, those who have read the previous topics may think about whether humans can fly with an infinite speed close to the speed of light.

Let's not consider for a moment whether our current technology can reach the speed of infinity close to the speed of light. Assuming that we can achieve such a fast speed, let's analyze whether it is reliable.

According to Einstein's special relativity theory, the faster an object flies in the universe, the slower the speed of time around it will be.

If a ship is allowed to fly vertically out of the galaxy at infinitely close to the speed of light, then it means that the time the ship experiences may be greatly reduced. Maybe less than a year to complete the goal.

But this time everyone ignores the point that is the limit of the mass increase effect.

Einstein in special relativity also mentioned the idea that

The mass of an object will change with the speed of the object, and when the speed of an object is infinitely close to the speed of light, then the mass of the object will also tend to be infinite.

Think about it, an object with a mass close to infinity. If it wants to continue to fly, then it needs an infinite amount of energy to power it.

In contrast, we do not seem to have found such an infinite power so far in nature, so trying to rely on the infinite speed of light to fly out of the galaxy is also a less-than-ideal view.

So far, there are two views in the scientific community that are most likely to allow us, humans, to make the long-distance cosmic leap.

One is the wormhole known as Einstein's Rosen Bridge, and the other is warp speed.

A wormhole, simply put, is a huge space bending and folding, making the two farthest locations, infinitely close to each other, in the infinitely close place will produce a channel, we humans through this channel can successfully achieve long-distance cosmic spanning.

Just as we usually take a shortcut means the same.

Warp speed is to compress the space in front, and expand the space behind, to achieve distance shortening, of course, these two theories so far are only hypothetical theories of mankind, so most people will think that the possibility of these two theories is minimal.

This has led to some speculation that we humans are not creatures trapped in the cage of the galaxy.

No matter how much we toss and turn inside, we will never be able to escape from the galaxy.

Of course, if we recall the history of the development of black holes, we may see some light.

A hundred years ago, when Einstein proposed the concept of wormholes, the same was not recognized by everyone. Because at that time, it was not possible to produce conclusive evidence that could prove the existence of black holes.

It was only on this day, April 10, 2019, that humans photographed for the first time a black hole 55 million light-years away from our planet. This is what confirmed that Einstein's speculation back then was correct.

The same is believed to be true for the concept of wormholes. It is only a matter of time to prove the existence of wormholes. Since Einstein came up with such a concept, I believe he must not have imagined it out of thin air.
