Physics between simplicity and cleverness

Have you ever wished to travel through time to the future to see how the world will advance, or to travel through time to the past to change mistakes you made previously, or simply to see ancient ages! Have you ever heard of black holes? Or asked yourself how they formed? Or why scientists called them space monsters? And what happens to those who enter or even approach them? And is it really true that there are theories and equations that suggest time travel, or going to other universes through black holes, might be possible! Are there types of time travel machines? What do they look like, and what are their features? And how did scientists originally deduce them?
