    I was just wondering how i could find the distance between earth and an object in space, i have heard of parallax formula but i am not quite positive on how it works.
    Any help or explanation would be greatly appreciated!

    Measuring the distance of a star via the parallax is actually triangulation.
    It goes a bit like this:


    Yet, CalSpace reports that this method only works when the stars are <500 ly away.

    This video of the Khan Academy explains how this works:

    There are no paradoxes in relativity, just people's misunderstandings of it.

    What?
    Your "equation" is meaningless with "c" on both sides of the equation.
    Even if you meant e=mc2 that has nothing to do with the topic as such.
    And, to top it off, c is the speed of light and time doesn't have a "velocity".

    It's supposed to be d=mc2 where 'd' is the velocity of distance.

    Not my equation, no...

    -'m' is Mustard
    -'c' is Cheese.
    Since c is squared, you have another 'c' which is Cut.
    But here's a tip: Finding the square root won't cut it.

    Shouldn't we factor in the length of height and the weight of red?

    Only if calculating it in in a Lagrangian Metric with more than one Hamiltonian for the system.
