Imaginary Numbers are not Imaginary Imaginary Numbers were once thought to be impossible, and so they were called Imaginary (to make fun of them). But then people researched them more and discovered they were actually useful and important because they filled a gap in mathematics ... but the imaginary name has stuck.

Whether your spouse inherits your entire estate depends on your state's laws. If you die without a will, your estate is divided according to state intestacy laws. If you had a will, your spouse's share is partly dependent on what you left her and whether you have surviving children or parents.
You can leave your assets directly to your heirs, or you can use your will to establish one or more trusts to receive the assets and distribute them at some point in the future. The danger of dying without a will is that a court in the state where you live will decide what happens to your assets. Its decision may not be what you would have chosen, and its deliberations can be costly and delay settling your estate.
