By measuring slight distortions caused by gravitational waves, LISA hopes to reveal their true nature and origin.
LISA will consist of three spacecraft in an equilateral triangle configuration, with each side 2.5 million kilometers long.
The European Space Agency (ESA) has approved a new mission called LISA to search for gravitational waves from space.
The European Space Agency (ESA) has given the green light to a new mission that will search for gravitational waves from space. The Laser Interferometer Space Antenna, or LISA project, is designed to be sensitive to unexplored phenomena and will consist of three spacecraft in an equilateral triangle configuration. Each side of the triangle will be 2.5 million kilometers long and by measuring slight distortions caused by gravitational waves, LISA hopes to reveal their true nature and origin.
The mission is set to take this science to a whole new level by reducing the noise encountered by ground-based instruments and lengthening its arms. The observatory will detect gravitational waves of different wavelengths than ground-based instruments or pulsar timing arrays, uncovering events of a different scale.
LISA is poised to capture predicted gravitational ringing from the initial moments of our Universe and offer a direct glimpse into very first seconds after Big Bang. Gravitational waves carry information on distance objects that emitted them, LISA will help researchers measure change in expansion rate with different type yardstick than Euclid and other surveys.
LISA is a gravitational wave detector in space that will be sensitive to unexplored phenomena.
The interferometer would follow the same basic principles as ground-based LIGO experiment but hardware will be placed 2.5 million kilometers apart, making it sensitive to an entirely new range of astronomical phenomena.
LISA design consists of an outer shell that absorbs dust and cosmic rays, a laser strong enough to reach 2.5 million kilometers and a telescope to focus incoming laser light.
LISA will spot impending collisions as much as a full year in advance allowing us to track the physics of their interactions over time.
LISA could pick up early gravitational fluctuations formed in the immediate aftermath of Big Bang providing new view into earliest history of Universe.

(50%)
The article is deceptive in several ways. Firstly, it states that LISA will be sensitive to unexplored phenomena when the hardware would follow the same basic principles as ground-based detectors like LIGO. However, this statement implies that there are no new or unique aspects of space-based detection which is not true.

The article states 'LISA will spot them (gravitational wave collisions) a full year in advance.'

Fallacies
(85%)
The article contains several fallacies. The author uses an appeal to authority by stating that the LISA project has already been approved and is expected to be successful based on previous tests. This assumes that past success guarantees future success, which is not always true. Additionally, the author makes a false dilemma by presenting only two options for detecting low-frequency gravitational waves: going to space or staying on Earth. The article does not consider other possible methods of detection and presents these as mutually exclusive choices.

The article is deceptive in several ways. Firstly, the author claims that LISA will study some of the universe's most enigmatic phenomena when it has not been proven to detect any new phenomena beyond what was already known from ground-based and pulsar timing array observations. Secondly, the article states that LISA is set to take this science to a whole new level by reducing noise encountered by ground-based instruments and lengthening arms of the observatory, but it does not provide any evidence or data on how much better LISA will be than existing technology. Lastly, the author uses sensationalist language such as 'it's finally happening', 'vastly reduce the noise encountered by ground-based instruments', and 'probe gravitational waves of lower frequencies than is possible on Earth' to create a sense of urgency and importance without providing any concrete evidence or data.

The article is deceptive in several ways. Firstly, it states that LISA will detect gravitational waves coming from events involving star-sized objects such as supernova explosions or merging of hyper-dense stars and stellar-mass black holes. However, this statement is not supported by any scientific evidence presented in the article. Secondly, the article claims that thanks to the huge distance travelled by the laser signals on LISA, and the superb stability of its instrumentation, we will probe gravitational waves of lower frequencies than is possible on Earth. This claim contradicts existing research which shows that it is not possible to detect gravitational waves at such low frequencies using current technology. Thirdly, the article states that LISA will help researchers measure the change in the expansion of the Universe with a different type of yardstick from the techniques used by Euclid and other surveys, validating their results. However, this statement is also not supported by any scientific evidence presented in the article.

The article is deceptive because it does not provide any sources for the claims that gravitational waves are predicted by Einstein or that they were first observed in 2015. These statements are false and misleading, as gravitational waves were actually proposed by him in 1916 and detected for the first time in 2015. The article also does not link to any peer-reviewed studies that support the claims about low-frequency gravitational waves or their origin.

The article contains two fallacies: Appeals to Authority and Inflammatory Rhetoric. The author cites the European Space Agency as giving the green light for both missions without providing any evidence or context about their decision-making process. This is an appeal to authority because it assumes that since a reputable organization has made a statement, it must be true without question. Additionally, the article uses inflammatory rhetoric when describing gravitational waves as 'ripples on the surface of a lake' and comparing them to background noise. While this analogy may help readers understand what gravitational waves are, it also creates an emotional response that is not necessary for understanding their scientific significance.
