What the revolutionary wave Observatory will actually see

Lisa, a 1.6 billion dollar wave of gravitational observatory, will release the way in which we see the wave of gravity – the endless disturbances of the expected space for the first time in more than a century and discovered only eight years ago.

In the fall, we published a deep diving in Lisa design and engineering obstacles that must be overcome to obtain a future space. Now, the scientists asked us about the actual data that Lisa will collect – what ideas that the data can result in and how these ideas will change our understanding of the universe, from the sources of gravitational ripples to the way that echo formed the universe.

Lisa: Simple, but it is accurate

Lisa antenna means laser interference space, and it consists of three spacecraft around the sun in a three -third formation. Lisa is an overlapping scale, which means that the task will inhale the gravitational waves using laser interference measurement – as it requires distances between the masses using an incredibly delicate laser beams about 5 million miles (8 million km), with each of the Lisa triangle, which includes about 1.6 million Mail (2.5 million km) of this length.

The laser is crucial but only one part of Lisa design – it is just a measure of measuring distances between three mineral cubes, one in both the three Lisa spacecraft. Cubes are made of a platinum gold bomb to reduce the magnetic that you can work on. Again, Lisa’s goal is to wander around space with anything positive that I have not won these cubes, but the space and the gravitational waves on which they were installed.

“The main idea behind the design is that we are launching these cubes,” said Savik Ford, an astronomical physicist at the American Museum of Natural History, in a call with Gismino. “We just want them to sit there and test the joy of space time without any other powers they work on, and this last part is the difficult part.”

Ford added: “You need the maneuvering of the craft because the fans (gold-platinum cubes) are falling, to ensure that the spacecraft itself does not drift into the masses and strike them, which will be terrible.”

As far as the complexity of Lisa, the graduate student at the then Ford at the time, Jake Bostelion has analogy: the technical challenge is similar to laser laser lashes from New York to Los Angeles (if the Earth is flat), and try to hit the fruit fruit with it. The laser and the fruit fly moves with the development of this process.

Ford said, the size of the engineering challenge is “frankly in thinking”, and I am very happy because it is not my section.

NASA provides several lisa elements, including its laser system, telescope systems and devices that will manage electric charging levels on the test cubes.

The frequency of orbits are determined by the number of times the entire orbit is completed around each other. Our gravitational wave detection devices are good in discovering certain frequencies for various reasons, but each current detector has one major restrictions: they are stuck on the ground.

Oracle is based on ancient black holes

The detection devices of gravitational waves differ in the types of tropical frequencies they discover. Ligo-Virgo-kagra-Ligo-Virgo-kagra-is great in detecting high frequencies, which are compatible with smaller blocks such as black holes the size of stars. But when these masses become slightly larger – for example, more than two hundred times the mass of our sun – their tropical frequencies are the same as the noise produced by our planet.

Ford said: “There is a hesitation in the first place where the Earth itself is so loud that the Earth is your problem,” Ford said. “You can not do it literally. You have to go to space, one way or another.”

In space, the pulsar timing lines make a useful stick for the largest black holes, although the Earth is still part of the equation. In this preparation, the observatory is monitored on the ground and a trusted light of light from the rapid spinning objects (vibrant stars); When the timing of this light is on the ground slight Delayed or accelerating, it is an indication that space time has extended or pressed with gravitational waves. In 2023, I found a group of Pulsar Time Cooperation a strong guide against the background of the gravitational wave in Plusar data.

The black holes that the timing of the timing of the vibrant plants see the billions of times in the sun’s mass and live in the midst of the monster galaxies – they even dwarf the Sagittarius A*, the black hole in the center of the Milky Way, which falls almost four million solar masses. If the black holes are porridge, it will be Lisa Goldellex. The task will inhale low -frequency gravitational waves that are impossible to distinguish between noise in Earth detection devices. However, the space observatory You may be able to discover The mergers of the huge black hole-black holes the size of the falling size into the high holes-besides the intimate diodes of built-in things and other shirts and backgrounds of astronomical physics.

Emmanuel Perte, a theoretical physicist, said: “The timing of the timing of the pulses gives us information about the random background of the huge black hole duets at very low frequencies, and LIGO has mainly set borders on the rates of different families of integration processes in the stellar mass,” said Emmanuel Perte, a theoretical physicist. At Johns Hopkins University, in a video call with Gizmodo. “Thinking has changed in different ways, but I say that the most interesting science we can do with Lisa is focused on huge black bilateral mergers, because this is something we cannot achieve on Earth.”

Evading noise in space

Although Lisa will have much less disturbances in space than Earth – i.e. zero – the observatory will have to undergo cosmic noise. There are things in the universe that make black holes more difficult to see them as they also emit gravity waves. More forms of distress from this integrated intertwined White dwarf dietsSurprising shells from the previous stars that revolve around each other and eventually merge, while raising space time in a process such as risk. The exception to this noise will be when the diodes So Expert it can be chosen individually and identify it for what it is. Double Double Costume, this “”Verification diodesAstronomers will help confirm the Lisa capabilities as soon as the task is in their position.

Lisa will discover a noise simultaneously from millions of sources, many of which are inside our galaxy, According to Nasa. Scientists will separate wheat from the peel with the help of a huge amount of data processing and installing data on the theories and current models of the known organisms of the universe. With more than a decade of time, Lisa is expected to launch, scientists are working on fake data challenges to prepare for the real deal.

Follow the cosmic development

“In fact, there are only two questions about astronomical physics,” which are we got here? “Are we alone?”.

Ford added: “We are not in the game of black holes in general to answer any relationship.” Are we alone? “But how we got here is very important to understand these black holes.”

Understanding the birth of the stars – and the role of these nuclear fusion ovens in the production of elements – is closely related to the presence of black holes. Moreover, the types of stars formed by galaxies and the quantity in which they are formed are connected to the mass and behavior of black holes in the nuclei of galaxies. Black holes can be of chaotic food – they often refute and overcome astral materials – which makes them active participants in the development of the universe around them.

“there We are numerous papers on the The so -called a little red Points Which – which a point outside Which – which there We are fainting Agns Which – which We are probably at from Accumulate particle black Berte said. ALl to this certificate Once once again points outside Which – which particle black Holes He should Ownership existing Beautiful early on in the date to the universe. He – she He has always He was A Puzzle, bUt that it To become ewhere more to A puzzle.”

Small -satellite telescope notes in the small Web Spots see light spots as they were when the age of the universe ranged from 600 million years and 1.5 billion years old. Although recent research indicates that the points are signs of the growth of the formerly beloved black hole in the early universe – and that cosmic models are not “broken” as suggested main headlines – notes will help detect the exact nature of confusing light.

Lisa will notice the fluctuation of black holes and the description of a group of things that are better integrated into our world. This information can also be applied to current cosmic models and prevailing theories, such as the general relativity of Einstein. Earth’s truth data (if it is permissible to express-we talk about space here) will be a convincing test of these ideas about the universe, one of which was validated when Ligo discovered gravitational waves for the first time in 2015. There is a lot of known unknown people in Yonder Black Black of Spacetime. But Lisa scientists are determined to retreat from the curtain – if only somewhat – on some of the most founding secrets of the universe.
