GENERAL RELATIVITY BACKGROUND

Developed by Einstein between 1907 and 1915

Explains how gravity ldquowarpsrdquo space and time

Equivalence principle

It is impossible to distinguish between the effects on

an object in an accelerating reference frame and the

effects on an object in a gravitational field

ELEVATOR THOUGHT EXPERIMENT

In an inertial reference frame light travels in a

straight path But to a person inside of the

accelerating elevator the light will appear to bend

towards the floor as it moves across the elevator

GRAVITATIONAL MICROLENSING BASICS

A microlensing event is caused by a single

object moving between the source object and

the observer

CONCLUSIONS

MatLab was able to be used to trace the rays of

Due to the scale of gravitational lensing systems

MatLab could not accurately create light curves

By rescaling the system MatLab could create

light curves for the single lens events

Not able to see the effect of the binary system in

CONCLUSIONS

MatLab was able to be used to trace the rays of

both single and binary lensing event

Due to the scale of gravitational lensing systems

MatLab could not accurately create light curves

By rescaling the system MatLab could create

light curves for the single lens events

Not able to see the effect of the binary system in

the light curve

CONCLUSIONS

MatLab was able to be used to trace the rays of

both single and binary lensing event

Due to the scale of gravitational lensing systems

MatLab could not accurately create light curves

By rescaling the system MatLab could create

light curves for the single lens events

Not able to see the effect of the binary system in

the light curve

CONCLUSIONS

MatLab was able to be used to trace the rays of

both single and binary lensing event

Due to the scale of gravitational lensing systems

MatLab could not accurately create light curves

By rescaling the system MatLab could create

light curves for the single lens events

Not able to see the effect of the binary system in

the light curve

CONCLUSIONS

MatLab was able to be used to trace the rays of

both single and binary lensing event

Due to the scale of gravitational lensing systems

MatLab could not accurately create light curves

By rescaling the system MatLab could create

light curves for the single lens events

Not able to see the effect of the binary system in

the light curve
