How can I obtain a patent which is universal all over the world?

First off, let me be a little picky about your terms. You want to know about a patent that is worldwide, not universal. There are no patents on Jupiter.

There also is not a worldwide patent right. Each country (or the few groups of countries who form these groups for patent purposes) has its own patents that grant patent rights in those countries. Even if you filed an application and obtained a patent in every country that has patents, you still wouldn’t have worldwide coverage because there are some countries without a patent system.

It is not likely that you need patent rights in every country anyway, so it all works out.
