Going beyond solar system with high speed

AI Thread Summary
Traveling at high speeds beyond a solar system or galaxy is theoretically possible, with solar sails estimated to reach speeds of 0.1 times the speed of light (0.1c) relative to the solar system. The discussion raises questions about the definitions of "high speed" and "beyond," as well as the physical and technological challenges involved. Utilizing techniques like Slingshot Orbits can enhance spacecraft speed by leveraging the gravitational pull of outer planets, reducing fuel requirements. The feasibility of such travel hinges on advancements in rocket technology and understanding of physics. Overall, while challenges exist, the potential for high-speed interstellar travel remains a topic of interest.

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.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
