Lisa, the gravitational gate, gravitational wave of 1.6 billion dollars that will be released in the next decade, will revolutionize the method that we see the gravitational wave – the bad disturbance of space for the first time that was predicted in the past century and was detected when Eight years ago
In the autumn, we published. Diving deep in Lisa's design And engineering obstacles that must beat in order to allow the future to enter space Now, we have asked scientists about the actual data that Lisa will gather – in -depth information that information can give results and methods that those in -depth information stand to change our understanding about the universe from the source of the waves. Gravity to the way that the sound resonates
Lisa: Simple but precisely
Lisa means an antennas antenna, laser and consisting of three spacecraft that orbits the sun in a fixed triangle. Lisa is a meaningful meter, which means that the mission will inhale the gravitational waves using laser. Interferometry – recognize the distance between the masses using a remarkable laser beam of about 5 million miles (8 million kilometers) miles (2.5 Nok.) Or that length
Laser is important But there is only one part of Lisa's design – just a measure of a distance between the three metals in the three Lisa spacecraft. The cubes are made of gold and white gold alloys to reduce magneticity that can perform their duties. Once again, Lisa's goal is to cruise through space without any positive things. There is nothing except space and wave of gravity.
“The basic concept behind the design is that we are launching these cubic cubes,” SAAVIK FORD, an astronomer of the American History Museum in calling with Gizmodo. “We just want them to sit there and experience the happiness of the time. Space without other forces that do with them and it is the last part that is difficult. “
“You have to make a ship while the masses (Golden white gold cubes) are falling to make sure that the spaceship does not float into the masses and hit them, which is very bad, “Ford added.
As far as understanding the complexity of Lisa, the bachelor's degree of Jake PostiorLione has comparison: Technical challenges are similar to the laser shooting from New York to LA (if the world is flat) and try to hit the eye of the flies. Fruits and it both laser and fruits are moving when the operation is resolved.
The size of engineering challenges is “Frankly diligence,” Ford said “and I was so smooth that it was not my department.”
NASA is providing many elements of LISA measuring tools, including laser systems, telescopes and equipment that will manage the electric charge in the test.
The frequency of the orbiting object is determined by the frequency that they do the full orbit around each other. Our gravitational wave detector is good to detect some frequency for many reasons. But every existing detector has one important limitation: they are stuck on earth
Arakel space for ancient black holes
The gravitational wave detector is different according to the type of orbiting frequency. The detector on the ground is the working area of Ligo-Virgo-kagra Excellent in high frequency detection, which corresponds to small mass such as black holes But when those masses are slightly larger – speak more than two hundred times more than the mass of our sun – their orbiting frequency is similar to the noise caused by our own planets.
“Basically, there is a frequency that the world is so loud that the ground is your problem,” Ford said. “You can't truly do. You have to go to space in one way. “
In the Palzar Space, the time of the Palzar makes the measure that is useful for the largest black hole, although the world is still part of the equation. In the settings, the dormitory on the planet checks the reliable flash light of light from the rapidly rotating object (Palzar); When the time of that light to the world is a little Delay or rush. It is an indication that space time is stretched or compressed by gravity. In 2023, a group of cooperation in determining the time -ray time found a strong evidence of A. Gravity background In the Palzar data

The black hole seen by the Palzar is usually a million times as the mass of the sun and lives in the center of the galaxies. -They are dwarf, Sagittarius A*, black hole in the heart of the Milky Way. Approximately four million masses If the black hole is a golden porosa, it will be a gold tilly. The mission will inhale low -frequency gravitational waves, which are impossible to distinguish the sound in the detector on earth. That said that the space gate May be detected The large black hole of a large black hole fell into a miraculous lump that has a close binary of compact objects and explosions and other astronomy backgrounds.
“Array Pulsar gives information about the random background for binary black holes at a very low frequency, and LIGO has specified the scope of different family rates at Johns Hopkins University in calling video with GIZMODO.” The idea changed in Various forms, but I will say that the most interesting science that we can do with Lisa is around a large black binary gallop because it is something that we can't try on the floor. “
Dodge the noise in space
Those Lisa will have more space disturbances than on Earth. – The idea center – Dao Dao must glide through the sound of the universe. There are objects in the universe that make the black hole more difficult to see because they also release gravitational waves. These annoying styles of these compact interloopers are White dwarf: The compact shell of the stars in the past that orbits each other and finally combined to stir the space in the process, such as the whisco in the mixer. The exception for this sound will be when binary. so Pronounce that they can choose a person and be accepted by what they are. These two -story swords “Inspection of binary“Will help astronomers confirm Lisa's ability when the mission is in the position.
Lisa will detect the noise from millions of sources, most of which are in our galaxy. As NASA– Scientists will separate wheat from the rice husk with the help of enormous data processing and adjust the information to suit the theory and models that are known of the universe. With over decades, Lisa is expected to launch scientists about challenges in simulation data to prepare for real management.
Follow up the evolution of the universe
“Only two questions in astronomy and them 'How do we come here? “And are we alone? 'Ford said. “Everything that we do is focusing on answering a little question of one and more, and those questions from time to time or those questions.”
“We are not in Black Holes in general to answer questions about 'Are we alone?' Ford added, “but 'How do we come here? How is it important to understand these black holes?”
Understand the birth of the life and death of the stars – and the role of these nuclear fusion fusions in the production of the composition – is Tied together separately To The appearance of the black hole– In addition, the type of star that is caused by the galaxy and the amount of occurrence may be connected to the mass and behavior of the black hole at those galaxies. Black holes may be a messy person – Inten The protrusion of the protagonist and Swing it out To space – make them Enthusiastic participants In the evolution of the universe around them
Observing the space telescope of a small red spot to see the stains of light, like when the universe is between 600 million years and 1.5 billion years, although Latest research Indicate that the point is a sign of the growth of black that was obscured in the first universe – and the astronomy models were not “broken” according to the recommended topic – Lisa's observation will reveal the exact characteristics of Mystery lighting
Lisa will notice the disturbance of the black hole and explain the characteristics of compact objects in our universe. That information can be applied to existing astronomy models and common theories, such as EINSTEIN's general relativity, ground truth information. (Therefore, talking about-we are talking about the area here) will be a test of stress from the calculation for those concepts about the universe, one of which was reputable when Ligo detected the first gravitational wave in the year. 2015, there are many people know. Unknown in a boring time of space But Lisa's scientists are determined to pull the curtain back a little. -In the most basic mystery of the universe
