A future spacecraft could help us learn more about the Big Bang.
When Europe starts the Laser Interferometer Space Antenna (LISA), scientists can examine the universe's beginning in greater depth.
A few years ago, David Dunsky attended a meeting in Japan where gravitational waves were discussed. Massive objects like black holes and stars accelerate, creating these ripples in spacetime.
At the time, Dunsky was a graduate student in particle physics, but it looked like he wasn't interested in that. Scientists who study particles try to find the deeper truth behind the physical rules we understand. For a long time, scientists have used high-energy particle colliders to test their ideas. Scientists can discover the fundamental parts of the universe by smashing particles together at unimaginable speeds. These are the high-energy events that happen over short distances. These events also tell us about the universe's beginning, when it was very small, thick, and hot.
Dunsky learned during the talk that future gravitational wave detectors, like the Laser Interferometer Space Antenna (LISA), might be able to study high-energy physics. The Laser Interferometer Space Antenna (LISA) has the potential to detect "cosmic strings," which are long lines of concentrated energy that may have originated during the creation of the universe. Dunsky, a cosmologist and particle physicist at New York University, became very interested in gravitational wave signals from the universe's beginning and how they might show high-energy physics beyond what current colliders can detect.
His shift toward gravitational waves as a way for particle physics to move forward shows how interest in the coming LISA experiment is growing and may be a sign of a larger change. It's been twelve years since a particle collider made a major discovery. The discovery of the Higgs boson at the Large Hadron Collider (LHC) in 2012 completed the Standard Model of Particle Physics, the main theory of known elementary particles and forces. Since then, scientists have proposed numerous new theories beyond the Standard Model. Remember, we can test these theories by building colliders.
Physicist Raman Sundrum from the University of Maryland said, "In the next 50 years, people are going to build colliders that are 10 times more powerful than the LHC in terms of energy." Testing grand unified theories, on the other hand, "would seem to take a collider that has 10 billion times the energy of the LHC," he said. According to these theories, a single force acting at shorter distances connects the three forces of the Standard Model.
Nature lets us see things that we can't make in a classroom. Specifically, the gravitational echoes of events from the beginning of time, when the universe was so powerful that physics beyond the Standard Model would have been common, may hold the answers.

David Dunsky is a cosmologist and particle physicist at New York University. He investigates how LISA might be able to detect early-universe phase transitions.
Particle scientists like Dunsky and Sundrum hope that will happen. They are now looking for a LISA to test their ideas. They came up with the idea for the project in the early 1980s and officially asked the European Space Agency (ESA) to support it in the 1990s. NASA worked together on the project for a while, but in 2011, the Americans gave up on it because of budget worries, leaving Europe to work on it independently. However, in January, LISA finally got the green light from ESA. The agency is now looking for business partners to start building it. The news comes after LISA Pathfinder, a pilot mission that tried the key technologies for the future observatory in 2015 and 2016, was a huge success.
