Going beyond solar system with high speed

Click For Summary

Discussion Overview

The discussion centers on the feasibility of traveling at high speeds beyond a solar system or galaxy, exploring both physical limitations and technological possibilities. Participants consider various aspects of high-speed travel, including definitions of speed and distance, as well as potential methods for achieving such travel.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions the definition of "high speed" and the meaning of "beyond," suggesting that the inquiry may involve both physical and technological considerations.
  • Another participant mentions that solar sails could potentially reach speeds of 0.1c relative to the solar system, implying that this could be considered a high speed.
  • A different participant proposes that a suitable rocket could achieve high-speed travel, and introduces the concept of a Slingshot Orbit, which utilizes the momentum of outer planets to provide additional speed without requiring excessive fuel.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility and methods of achieving high-speed travel beyond a solar system or galaxy. There is no consensus on the definitions of "high speed" or "beyond," nor on the best approaches to achieve such travel.

Contextual Notes

The discussion includes unresolved questions regarding the definitions of speed and distance, as well as the technological limitations of current propulsion methods. The implications of using techniques like Slingshot Orbits remain unclear.

Hey guys,

Is it possible to travel with high speed beyond a solar system or a galaxy? Or is there something that will prevent something to move at high speed outside a solar system or a galaxy?

Yes
 
How fast is "high speed"?
How far is beyond?
Is this a physical quesstion or a technological question?
 
FYI, solar sails are estimated to reach 0.1c relative to the solar system. I'm assuming that counts as "fast".

A suitable rocket could achieve what you say but you can do the same thing by using a Slingshot Orbit (see this link) which uses the momentum of the outer planets give spacecraft an extra boost so they do not need to carry so much fuel for a given payload.
