কীভাবে Gravitational Wave গণনা করবেন
Gravitational Wave কি?
Gravitational waves are ripples in spacetime caused by accelerating massive objects. They were predicted by Einstein and directly detected in 2015.

সমাধান করা উদাহরণ
ইনপুট
Two 30 solar mass black holes merging, distance = 1.3 billion light-years
ফলাফল
Strain ≈ 10⁻²¹ (first detection)
GW150914 event
এড়ানোর সাধারণ ভুল
- ✕Overestimating gravitational wave amplitude from typical sources
- ✕Confusing waves with radiation pressure effects
সচরাচর জিজ্ঞাসা
How are gravitational waves detected?
LIGO uses laser interferometry to measure changes in arm length from gravitational wave strain.
Do gravitational waves carry information?
Yes, they encode details about the source: masses, spins, orbital parameters, and cosmological distance.
