Want to see it in one day Go to 16 sunrises? Enjoy floating in zero gravity? Be one of the few people to gaze at the Earth from space? Just wait another 4 years and spend an astronomical sum of $9.5 million, and you will achieve it all.

Recently, the American space technology company "OrionSpan" announced in California that it plans to build the world's first luxury space hotel "Aurora Station" in 2021 and launch manned travel the following year.

Company officials said that the fully assembled space station "Orion" they developed can accommodate 6 passengers (including two astronauts) at the same time, and can be put into use after launch in low-Earth orbit. Start a 12-day trip.

“We want to get people into space because it’s the final frontier of our civilization,” company founder Frank Bunger told Bloomberg.

The US "Washington Post" stated that Banger revealed that "due to the decline in launch costs," the company has lowered the price to less than $10 million, which is lower than ever before. According to reports, in 2001, American billionaire Dennis Tito spent $20 million of his own money to complete a seven-day space trip.

10 million US dollars for 12 days, which is approximately US$791,660 per night. CNN stated that this travel route is beyond the budget of most people, but the "Orion" company insists that it will allow passengers to be "real astronauts."

“This experience is not for everyone. ‘Aurora Station’ mainly caters to those who are passionate about space and astronomical research,” Banger said. “We are not just selling ‘beach tours’ '.

We're selling the experience of being an astronaut. You can expect that there will be some people willing to pay to have that experience."

Traditionally, tourists. Typically 24 months of intensive training are required before entering space. Orion has simplified this "astronaut certification process" to three months and is covered by the total cost.

According to CNN, the company has a professional team composed of aerospace veterans with more than 140 years of space experience.

After entering the "Aurora" space station, wealthy tourists will fly at high speed in low-Earth orbit at an altitude of 322 kilometers for 12 days. CNN said they should not be bored.

First of all, the space hotel will orbit the earth every 90 minutes, which means they can see 16 sunrises and sunsets every 24 hours. Enjoying the excitement of zero gravity, they can freely shuttle around the hotel and see lasers in the north and south of the earth from the hotel window.

Secondly, there are a series of research and experimental activities in the space station, such as growing food in low-Earth orbit, soaring over hometown, etc.

Furthermore, they can also video chat with their relatives on Earth through high-speed wireless networks, imagining the "Heroes' Welcome Ceremony" they will enjoy when they return to Earth.

Currently, the space hotel is accepting reservations on the official website of the Orion company, with a deposit of US$80,000. If the applicant finds that he cannot meet the full payment of US$9.5 million, the deposit can be fully refunded.

In fact, "Orion" is not the only company boldly advancing "elite space travel."

CNN said that Axiom, a company headquartered in Texas and run by former managers of the International Space Station, plans to send tourists to the International Space Station starting in 2019 and by 2024. Launching its own commercial space station into orbit.

The British company Virgin Galactic also aims for "short-term suborbital commercial travel", pricing this service at US$250,000.

Company founder Richard Branson initially said space flights would begin in 2009, but an official date for the "maiden voyage" has not yet been determined.

“Everyone is predicting that launch prices are going to go down,” said Banger. “Almost every week there’s another rocket launch company with a new, cheaper, faster, better way. Entering orbit.”

The Washington Post stated that the announcement of Orion’s luxury space hotel comes at a time when the commercial space industry is booming.

In February this year, SpaceX successfully launched the Falcon Heavy rocket at the Kennedy Space Center, becoming one of the milestone events that once again ignited people's interest in space.

The launch also raised the question: Can SpaceX and other private companies maintain momentum and deliver on their promise to return humans to space?

As the Trump administration attempts to adjust the U.S. This possibility is expected to increase as NASA's role allows private industry and international partners to participate.

There are also skeptics who believe that after all, there are only a very small number of tourists who have spare money to travel to space, and the future of the space travel market remains to be seen.

In this regard, Banger said that in addition to hotel services, the space station also has multiple uses: providing fully chartered travel to other commercial companies, providing support for zero-gravity research and space manufacturing, etc.

“Our structure is: we can easily increase production capacity and grow in step with market demand.”

CNN said that starting from the space hotel, the “Orion” company is already planning the next one. Big goal: launch the world's first residential apartment into space.

How to realize interstellar navigation and space travel:

Human beings have been exploring the unknown starry sky. How to realize interstellar navigation is a huge challenge for humankind’s current science and technology. Challenge, leaving the solar system requires the third cosmic speed, but the Centauri galaxy closest to us also takes 4.2 light years, so it will take 4.2 years for a spacecraft using the curvature of light speed to reach the nearest perseverance system. It is not known whether there is life in this galaxy. Planets, let me share with you how to achieve interstellar navigation and space travel.

How to realize interstellar navigation and space travel:

1. Human beings must create light speed spacecraft or sub-light speed spacecraft (nuclear fusion technology can be used to achieve sub-light speed spacecraft, or Curvature of light speed ship)

2. Humanity’s nanotechnology has achieved breakthroughs, giving humans the opportunity to live forever, so that they can watch the wonders of the universe during long interstellar voyages

3. Even if nanotechnology cannot be used intelligently, humans at least need to have stable hibernation technology

4. Human beings need to ensure that their speed reaches the first level of super light speed, so as to avoid being absorbed by low-latitude space or escaping. The attraction of black holes

Why the expansion rate of the universe is 13.8 billion years:

As for the origin of the universe, the current mainstream scientific community generally accepts the Big Bang theory (Big

Bang). The universe began at a singularity with extremely high temperature and density. The observed cosmic microwave background radiation and the expansion of galaxies moving away from each other provide support for this theory.

1. Hubble time

The degree of distance between galaxies is expressed by the Hubble constant. Compared with the long history of the universe, the Hubble constant in human time should obviously be a fixed value. However, due to the method of measuring the distance between galaxies, it is very difficult to accurately obtain the Hubble constant. Hubble initially set the Hubble constant at 500, and the Hubble constant has been continuously adjusted since then.

The European Space Agency announced on March 21, 2013 that based on the measurement results of the Planck satellite, the new Hubble constant value was 67.80±0.77(km/s)/Mpc (Mpc means hundred Ten thousand parsecs (approximately 3.26 million light years), that is, for every additional 3.26 million light years (or every 3.26 million years), the speed of the galaxy away from the earth increases by 67.80 ± 0.77 kilometers per second.

The Hubble constant is the expansion slope of the universe. If we trace it back to the point where the volume is zero, just find the reciprocal of the Hubble constant.

1Mpc=3.09×10^19km

1 year=3.16×10^7 seconds

The result is about 14.26-14.59 billion years. This time is called Hubble time.

If the universe has been expanding at this Hubble constant, Hubble time is obviously the age of the universe. But in the history of the universe, the Hubble constant is a variable.

If we assume that the cosmological constant (dark energy density) remains unchanged, the expansion speed of the universe should be slower in the front and faster in the back, which means that the universe is not always expanding at the current Hubble constant, so this Hubble Time cannot yet be used as the age of the universe. But coincidentally, the Hubble time calculated based on the current Hubble constant is very close to the age of the universe.

2. The age of the universe

The age of the universe is calculated from the microwave background radiation, because this is the first light in the universe.

In the early days of the Big Bang, the temperature of the universe was extremely high and particles were generally in an ionized state. Photons constantly collide with particles during their movement and cannot move freely. They can only constantly change their paths. After a period of time, the temperature drops, protons and electrons combine into neutrons, a stable atomic structure is formed, and the density of matter decreases. At this time, photons decouple and begin to emit freely.

Scientists estimate that the first light was produced around 380,000 years after the Big Bang, filling the entire universe with huge energy. As time goes by, the universe becomes larger and larger, and the temperature becomes lower and lower. Now only the embers of the big bang of about 3K remain.

The characteristics of microwave background radiation are the same as the blackbody radiation of the absolute temperature scale 2.725K. We know that the total energy in the universe is certain. When the universe expands, the energy density decreases and the temperature also decreases. Therefore, after getting the temperature, we can roughly get the size of the universe, and then get the expansion rate based on the red shift, and we can basically know when the universe started to expand.

At the same time, the European Space Agency also announced a map of the cosmic microwave background radiation based on data returned by the "Planck" space probe. This is the most accurate panorama to date that reflects the early days of the universe. It has almost perfectly verified the Standard Model of the Universe and accurately calculated the age of the universe to be 13.82 billion years.

3 The Boundary of the Human Observable Universe

The limited history of the universe, coupled with the limited speed of light, will inevitably lead to the observable universe being Limited. The farthest universe we can observe is not simply the speed of light multiplied by the age of the universe, but also multiplied by a scale factor. Assuming that a beam of light emitted by a celestial body 13.8 billion years ago now enters our line of sight, the photon has traveled 13.8 billion light years. At the same time, space itself is expanding, and this expansion even exceeds the speed of light. This means that when we observe this celestial body, it is already farther away from us.

The most distant galaxy we can currently observe is 46 billion light-years away from the Earth. As time goes by, due to the overall expansion of the universe, all galaxies will become farther and farther away from us, until they become dead.
