Gravitational Waves
Transcript
Discovery &
Further Research
Significance...
How are they measured?
- Important for two reasons...
- Open new windows for observational astronomy
- help us understand black-holes, neutron stars, space and time, merging of binary systems, etc.
- expand on the origin of the universe
- examine the center of galaxies
- Verify Einstein's prediction of the theory of relativity
- light and gravitational waves travel at same speed?
- First discovered by Albert Einstein during his study of theory of relativity
- Other scientist have investigated gravitational wave further...
- M.E. Gertsenshtein and V.I. Pustoviot
- Joseph Weber and Russell Hulse
- Rainer Weiss
- Research teams
- National Science Foundation (NSF)
- LIGO Team (1000+ physicists)
- Cannot just measure the distance
- Measured using the speed of light
- speed of light never changes
- time to travel from one location to the next would
- LIGO

Problems
for Physicists
- Unable to prove
- scientist could never replicate the work of other scientist
- recently...
- matching data was collected from two separate locations
Statistical data collected from LIGO & a Simplified version of LIGO
What are
gravitational waves?
- Basically...
- ripple in time and space
- anything spinning around something else causes them
- to be detectable they are caused by massive objects moving very fast
- black holes, neutron stars, combination
- stretches or compresses space
