But your basing that on conventional means .. the theory of what we'll call "warp speed" already exists which will allow us to all intents and purposes travel faster than light (altho -not travelling faster than light if you know what I mean) - yes, the energy requirements are mind-boggling but the theory exists .. we "just" need to find a way to harness the energy to utilize it (or experiment to begin with, obviously).
The Kardashev Scale has already laid out a theoretical model of civilisation and their command of energy. It breaks civilisation into 3 types. Type 1 civilisations can fully harness the energy on their own planet (ie, natural resources). Type 2 civilisations can fully harness the power of a star (and not just sticking a solar panel on your roof) .. Type 3 civilisations can fully harness the power of a galaxy such as black holes and other wildly energetic things out there.
We haven't even reached the starting point of a Type 1 civilisation. Ok, its speculative and only theory and we have nothing to apply it to other than ourselves - but given how low we are on that scale - what will we be able to do when we can harness the power and energy contained within a black hole (natural or man made)? I'm not a physicist - I don't know what the implications of this would be - but I do know its a zillion times more powerful than a tank full of decayed trees. Enough to warp space?
Yes, because black holes do.
Well the energy "within" a black hole is gravitational. Its not a hole either, its just seen as a space in space because the gravitational pull is so strong even light cannot escape it.
In fact gravity is so strong it would atomise every material known to man including man himself. So to harness this energy would require some sort of "forcefield" that was generated using even more energy than produced by the blackhole and that would be counterproductive (to use more energy to harvest energy of less value)
The Theory is that because it can warp light, it can warp time, but as it says its only a theory.
One way of traveling faster through space is using an idea called warp drive. In present physics theory, no material object such as a spacecraft can travel faster than the speed of light. In the theory of relativity mainly developed by Albert Einstein, matter like electrons and space crafts cannot travel faster than the speed of light. According to the theory of relativity as an object’s motion speed increases, its mass increases. At slow speeds this mass increase is not noticeable, but as the object motion speed approaches the speed of light, its mass increases dramatically. There is an equation in modern physics theory that relates an objects mass to its motion speed. The equation is: m=M divided by[1-(vdivided by c)2 ] 0.5 . The variable M is the rest mass of the spacecraft when it is not moving.
Variable m is the mass of the object that is traveling at fast speed v and the constant c is the speed of light in vacuum space. This increase in mass as the object speed increases limits how fast the space craft move. As the speed v approaches the speed of light c the relativistic mass becomes to large to allow the space craft to travel faster than the speed of light c.
The theory of relativity also says that as an objects motion speed increases the rate of time flow of the object or spacecraft slows down. A pilot in a space craft traveling at fast speeds would age slower than a person on earth moving at a slow speed. This slowing down of the rate of time flow is called time dilation. This slowing down of time is assumed to be a property of space in the object itself not a property of matter. The changing of time flow rate due to the increase in motion speed in space enables space and time not to be described as separate things.
The relativity equation for time dilation is : t=T×[1-(vdivided by c)2]0.5, where T is the time elapse in a slow moving object such as the earth, and t is the time elapsed in a fast moving mass speed v.
The difference in elapse time of t and T is time dilation. Einstein mathematics may indicate that the laws of physics themselves resemble mathematical objects in a four dimensional space.
Curved space-time is also called Riemannian geometry which is a maths which involves working with curvature in many dimensions. Space affects time, so they are interrelated.
Now space is called space-time, because time and space are not separate things. Space-time can be thought of as having four dimensions; the three dimensions of ordinary three dimensional space and one the dimension of time. We can only imagine a portion three dimensional space easily; seeing some space as having four dimensions is difficult to visualize.
Gravity can pull objects or masses to each other. Masses likes the earth or a space craft emit gravity. In relativity theory, gravity is assumed to be a curved space-time or warped space-time. A mass in space-time curves the space-time in the mass and around the mass to produce gravity.
Does that make sense......my brain hurts
