No, I am not. I will rephrase my question for you. What is cutting edge in the field of gravitational lensing? Alternately, what are some likely developments or discoveries that are expected in the field in the near future?

Thank you, gravitational lensing has grown a lot in especially in the last 30 years. I am interested to know what's on the horizon, or what scientists think is on the horizon

What do physicists expect to do or find with lensing in the next fifteen years? Is there some specific object(s) they are looking for, or a concept?

How does that help me find the change in mass?

it Why would I pick a different reference frame? - Why would the equation not be useful? So the equation that I entered: Einitial for one object plus Einitial for the second object = Mc^2 - no gamma on the second side. - if we tried to use this equation for this problem, it would not simplify...

I Would use conservation of momentum, which I mentioned, but since I have two variables, I would also need an energy equation. So the question is, do I understand said equation correctly, that the composition mass stops moving after collision, and if so, what do I do for a composition function...

Homework Statement An object with mass of 900 kg Is moving at a speed of 0.85c when it collides with an object at rest with mass of 1400 kgs. Find the speed and mass of the composite object. Homework Equations mc^2/gamma +mc^2/ gamma=Mc^2 The Attempt at a Solution My issue is that I am not...
