Is Interstellar Travel Impissible?

[martin-w 3,234]

Is that the answer to the Fermi Paradox? It's just too word not allowed hard, so nobody bothers?

I heard it mentioned once, I'm not sure where, that rather than actual Interstellar travel, people might instead lock themselves in Matrix type worlds where thier every dream can come true.

In fact oh, I've seen speculation about purely digital civilizations around black holes at the end of time.

I'm impissible,  Your topic is impossible! 😀

Hmmm. Given how far we’ve come with flight simulators in just 30 years - how real will things be in 300, or 3,000, or 30,000 years. What will simulators be like in 3 million years? Is it really so hard to believe that they will be indistinguishable from reality? 

Or are we already in that simulation? Is MSFS a simulation within a simulation? True story: I was on a real world flight yesterday, and I could swear I saw terrain popping when I looked out the window. I probably need to take a break from MSFS - but then again…

It may not be impissable but it's really hard................

In my view nothing is impissable, not anything, so everything is pissible.

I don't think it's impossible.  I am convinced that it is possible to travel faster than light by foreshortening or bending space rather than traveling through it.

We just need to figure out how to do that, and then come up with a super-duper power source for the engine, as I'm sure it will require a tremendous amount of power.

If we can develop a space craft that can continue to accelerate at 1G,, and if the faster you travel the slower the rate of time becomes, then that makes it a game changer. Half the journey you are in acceleration phase, and the other half of the journey you are in deceleration phase, and you can maintain constant gravity this way

Anyone who used to have the old Microsoft Space Simulator would have experimented with this theory as it did a great job of allowing you to travel around the universe like this. It would be awesome if Microsoft could do another version of Space Sim that was a lot of fun

The issue is mass. It's something like trying to pass a gallstone. Impissible!

[RichieFly 728]

If you define travel as leaving and arriving, then no. The calculations I've seen suggest that with a 1G acceleration/deceleration model, even the closest stars would take a really long time. Probably beyond a single adult lifetime.

"The speed of light is 670, 616, 629 miles per hour and I wonder what accelerating to that does to the human body?", asked Goose.

"Close your mic, you sceptic!" said, Maverick. "We buzz Pluto in 3, 2, 1...."

I'm thinking many haven't watched the video I posted. 😁

The conclusion drawn is that its not the distances involved that's the biggest issue, its actually the interstellar medium itself. 

Space isn't a void, its full of microscopic dust particles. 

 

Absurdly large distances: Most solvable. Large light sales, compact fusion drives, matter antimatter engines are foreseeable in the future.

Interstellar Medium: Full of gas and tiny dust grains, so at relativistic speeds every molecule becomes a tiny bullet. Number one deal breaker. At 0.2C a grain of dust 1mm wide can deliver a few hundred million joules of energy. Obliterating our space craft.

But fear not space cadets. The conclusion drawn is that we will need serious shielding and our speed may be limited.

Yo, Martin....ever hear of a navigational deflector?  Bingo!

Space is a dangerous place, lots of hazards involved in space travel.  I doubt all the issues will be solved within my ever shortening lifetime.

Though we may the solve the interstellar travel concept in the coming centuries, the real question will be: Is there a habitable place somewhere out there to land on?
