A Long-Lost Branch of the Nile Helped in Building Egypt’s Pyramids

* How would it feel: You and your fellow audience will be comfortably placed in a force field bubble that will (1) allow you to watch the event of your choice freely but (2) will make you invisible to all lifeforms you are observing; unfortunately (3) you will not be able to interact (talk with observed people, give/take anything to the observed locales etc.) and (4) cell phones and other recording devices are prohibited. This is to ensure safety and avoid any time paradoxes. Refreshments are served during the visit. For anthropological time-scenes simultaneous translation (if possible) will be provided.

* How much would it cost: Everybody, of course, has a long list of historical events they'd like to observe. Pricing of the visit depends on how many people would like to visit a particular time-scene (e.g. Caesar's stabbing). Only selected time-scenes are available. For customers that prefer to visit a locale over an extended amount of time, e.g. how did migration from Africa happen over 10,000 years, a time travel as a service pricing will be getting. Another factor that will increase pricing is the environmental violence of the event, e.g. one of the priciest time-scenes to visit is the Chicxulub impact, which is the limit of current safety technology, i.e. visiting the Theia impact is not supported.

Some suggested time-scenes that are top rated include:

* Natural/zoological time-scenes: Chicxulub impact (highest rated ever event), start of the Zanclean Flood (https://en.wikipedia.org/wiki/Zanclean_flood), Wet Sahara (https://en.wikipedia.org/wiki/African_humid_period), this is one of the most affordable visits, first steps of a vertebrate on land (https://en.wikipedia.org/wiki/Vertebrate_land_invasion), typical day in the Upper Cretaceous period (at least one sighting of a T-Rex is guaranteed)

* Anthropological time-scenes: Cleopatra's suicide, fall of Constantinople (single day, package for the whole siege is available as is visits to all 34 sieges over time), Socrates presenting his defense (can be combined with his suicide for a discount), conclusion of the Battle of Thermopylae (single day, package for all three days available)
