1. Strong lensing: where there are easily visible distortions.2. Weak lensing: where the distortions of background objects are much smaller and can only be detected by analyzing large numbers of objects to find distortions of only a few percent.3. Microlensing: where no distortion in shape can be seen but the amount of light received from a background object changes in time.

Wonder where you got that.Eärendil - IIRed Anvil - IIatomicknight - ICoatlicue - Ibasf11214 - IAbelNightroad-12Ellusionary Mage - 2MageKing-2Eärendil-2monomer-2akkionimusha-2306. What is the Shapiro Effect?

the shapiro effect is one of the four classic solar system tests of general relativity,and radar signals passing near a massive object take slightly longer to travel to a target and longer to return (as measured by the observer) than it would if the mass of the object were not present.

..... to find the change in time or something......... :shifty:G is the Gravitation Constant, M is the Mass, the c must be the speed of light, could R be the radius?.... and what is x?....am i even on the right track?and yea lol wikipedia......

Your constants are right but just think about every equation you've ever seen to see what x is.Where's Ody when you need her

This equation computes the Shapiro delay.By the way, I don't mind this quiz being taken, you could just have dropped me a PM... but nevermind

I figured you'd be gone so I didn't take care too. If you want I can send you one now :waaa:Oh and you're right, but you know that...Eärendil - IIRed Anvil - IIatomicknight - ICoatlicue - Ibasf11214 - IAbelNightroad-12Ellusionary Mage - 2MageKing-2Eärendil-2monomer-2akkionimusha-2Ish-2308. What is the basis of celestial mechanics?you could just have dropped me a PM

I believe that the Perturbation theory is used for finding new planets, by using "perturbations" in a near by planet's orbit.

Not really the finding of planets but something else about them.

it's for knowing when a star is finishing it's hidrogen and becoming a nova or supernova

You asked what it is for, that is what it is used for.The Perturbation theory is for explaining "perturbations" in an object's orbit, due to an unknown gravity field.Neptune and Pluto(*sniff*) were discovered using this theory.

I'm pretty sure sigma is right. It's used to find the motion of a planet. I think.

No, you are using the wrong part of the theory to answer or using wikipedia.

Actually it is a mathematical method used to find an approximate solution to an equation that cannot be solved exactly. This theory was used in celestial mechanics where it was used to make small corrections in the paths of planets.Hope thats right .

dark energy is a hypothetical form of energy that permeates all of space and tends to increase the rate of expansion of the universe.Dark energy is the most popular way to explain recent observations that the universe appears to be expanding at an accelerating rate.According to me,dark energy currently accounts for 74% of the total mass-energy of the universe.

Hilarious.According to me,dark energy currently accounts for 74% of the total mass-energy of the universe. You mean according to wiki?Since this quiz hasn't been updated for 2 years (my bad). Some of the questions may be duplicates.TyphoonMaster is correct. Eärendil - IIRed Anvil - IIatomicknight - ICoatlicue - Ibasf11214 - IAbelNightroad-12Ellusionary Mage - 2MageKing-2Eärendil-2monomer-2akkionimusha-2Ish-2nefie-2TyphoonMaster-2Planet time :o311. Pluto is no longer a planet. What is it called?
