Traveling Fast and Infinite Mass

In summary, Hyperspace said that if we wanted to use black holes for transportation, we would have to go faster than the speed of light. However, this is impossible because you would obtain infinite mass.

Now somewhat near the end of Hyperspace, It spoke of black holes and how light can't escape. Doesn't that mean that if we wanted to use black holes for transportation then we would have to go faster than the speed of light?
Which I've read many times is impossible because you would obtain infinite mass. I had a strange thought to, In Hyperspace it said to imagine a subway train that would go near the speed of light, it would get squished up and distorted and then expand to fill up the station when stopped. Doesn't Time Slow down when you go that fast? So say you take a 2 minute train ride, wouldn't that be a lot longer off of the train?

The solution of Einstein's equations for the case of a rotating black hole suggests that it might contain inside it a sort of wormhole to "somewhere else", but the solution doesn't say where. To use it (and this is generally held to be impossible by most physicsts) you first fall into the black hole, somehow avoiding the tidal forces that will tear you apart, then enter the mouth of the tunnel, traverse it, and come out wherever it goes. Whether that is inside another black hole or not is not said. Generally nobody except maybe Kaku thinks this would ever be possible even in principle.

Well before we Find a way to traverse black holes we should find a way to build colonies in space so we can take an entire city of people because do to the time dialtion everyone you know that hasn't gone through the black hole would die because and hour of black hole travel would be like forever on Earth am i correct?

Yes, seen from far away, the time to fall into a black hole would take literally forever. But to the people falling, it would happen fast. This is according to the usual accepted understanding of black holes.

Really? I happen to remember several physicists working on such ideas, including traversable wormholes by Kip Thorne and spinning black hole rings by Roy Kerr. Black Holes & Time Warps by Kip Thorne even goes into detail on how something like this could be accomplished.
 

1. What is the concept of "Traveling Fast and Infinite Mass"?

The concept of "Traveling Fast and Infinite Mass" is a theoretical concept in physics that explores the idea of an object traveling at or beyond the speed of light and having an infinite mass. This concept is based on the theory of relativity and has been a topic of interest for many scientists and researchers.

2. Is it possible for an object to travel at the speed of light?

According to the theory of relativity, it is not possible for an object with mass to travel at the speed of light. As an object approaches the speed of light, its mass increases infinitely, making it impossible to accelerate further. However, massless particles such as photons can travel at the speed of light.

3. Can an object have an infinite mass?

No, it is not possible for an object to have an infinite mass. As mentioned earlier, the mass of an object increases as it approaches the speed of light, but it cannot reach an infinite value. This is because the amount of energy required to accelerate an object with infinite mass would also be infinite.

4. Why is the concept of "Traveling Fast and Infinite Mass" important?

The concept of "Traveling Fast and Infinite Mass" is important because it helps us understand the behavior of objects at extreme speeds and how they may interact with each other. It also plays a significant role in theories such as the Big Bang and black holes, where objects travel at or beyond the speed of light and have immense mass.

5. Are there any practical applications of this concept?

Currently, there are no practical applications of the concept of "Traveling Fast and Infinite Mass." However, scientists continue to study this concept and its implications for space travel and understanding the universe. It may also have potential applications in future technologies, but more research is needed to fully understand and utilize this concept.
