Nothing in the universe ever changes, it's this static thing.but within it, you experience it, like being in a roller coaster. The human descendents are destined to build the tesseract. Cooper tried to change the past when he desperately tapped the message 'stay' in the bookshelf, but he just ended up fulfilling what had already happened: his past self ignored the message his daughter deciphered, again. The future is already set, and everything is as it will be and always has been, and it can't be changed any more than the past can. It's just part of the space-time structure. There was never a time-line without the time-loop, without that point of interaction between the future and the past. This movie's concept treats it like a physical dimension. You're looking at time like a linear thing. now for the very 1st time.who created the worm hole? i am talking about the 1st thread of the timeline. for them to do that, they would need the worm hole. then do we have different time lines in the movie? I mean.for humanity to not be extinct, they had to escape from earth. Much of the R&D is classified), but they are one of the promising engines for future cheap spaceflight. Scramjets are still in the testing and experimentation phase (That we know of. To compound the issue, liquid hydrogen has low density - so more space is required to store it - increasing the over all weight. So a scramjet is possible to escape orbit, but only at low weights. The Rangers however could've been made of carbon fiber materials, making them somewhat lighter for their size. To compare, the RD-0410 rocket engine is one of the lowest performing and has a TWR of 1.8, with a mass of about 4,400 lbs. The disadvantage of the scramjet is that there is a weight limit, since it has to be able to reach mach speeds and has a TWR of only 2. Advantages include lower fuel requirements (liquid hydrogen) and making an oxidizer unnecessary (which is heavy so taking that out reduces weight). This would be in line with the very streamlined design of the Ranger, which was very flat. Scramjets require that the vehicle travels at mach speeds for maximum efficiency since it is designed to take advantage of the supersonic air speed for combustion, and is designed to minimize drag while maximizing thrust. The F-1/Saturn V is the heaviest rocket we've ever used at about 1.74 million lbs, and has a Thrust to Weight Ratio (TWR) of 94.1Ī Scramjet (Supersonic Combustion ramjet) is possibly what they used in Interstellar for the Rangers, or at least was the inspiration for it. When they were first going up to the Endurance, they were carrying 4 people, TARS, and all their supplies and equipment. They provide the highest thrust of any engine and are a proven (and cheap) fuel source and are best used to propel a lot of weight. Traditional rocket propulsion uses internal combustion heat engines. Actually, there's a reasonable explanation.
