Why is the detection of gravitational waves important?
Detecting and analyzing the information carried by gravitational waves is allowing us to observe the Universe in a way never before possible, providing astronomers and other scientists with their first glimpses of literally un-seeable wonders.
What was the impact of detecting the first gravitational waves?
In fact, by the time gravitational waves from LIGO’s first detection reached us, the amount of space-time wobbling they generated was a 1000 times smaller than the nucleus of an atom! Such inconceivably small measurements are what LIGO was designed to make.
How LIGO the Laser Interferometer gravitational wave Observatory help us to know about existence of gravitational waves explain briefly?
When a gravitational wave passes by Earth, it squeezes and stretches space. LIGO can detect this squeezing and stretching. Each LIGO observatory has two “arms” that are each more than 2 miles (4 kilometers) long. The observatory uses lasers, mirrors, and extremely sensitive instruments to detect these tiny changes.
What do gravitational waves tell us about black holes?
Gravitational waves could soon provide measure of universe’s expansion. LIGO Detects Fierce Collision of Neutron Stars for the First Time—The New York Times. LIGO announces detection of gravitational waves from colliding neutron stars. The black-hole collision that reshaped physics—Nature.
Why are waves so important?
Waves are a very important and necessary part of the workings of our planet; the motions they create perform a vital role in transporting energy around the globe and shaping the coastlines. Oceanic swells are messengers of energy.
How did LIGO help scientists find gravitational waves?
After a decades-long quest, The MIT-Caltech collaboration LIGO Laboratories has detected gravitational waves, opening a new era in our exploration of the universe. By further analyzing the gravitational signal, the team was able to trace the final milliseconds before the black holes collided.
What do the LIGO discoveries mean?
The LIGO discoveries have “launched a new era in astronomy,” according to a statement from Northwestern University, where scientists are studying the gravitational waves to try to understand the black holes that created them.
Why are there so many detectors for gravitational waves?
Noise is a huge problem in gravitational wave detections. Hence why there are detectors in different places. We know that gravitational waves travel at the speed of light, so any signal is only legitimate if it appears in all the detectors at the right time interval.
What is the biggest black hole ever observed in gravitational waves?
LIGO and Virgo recently observed a black hole merger with a final mass of 142 times that of the sun, making it the largest of its kind observed in gravitational waves to date.
