by Gradytevin 1 year ago

Interstellar travel is indeed possible, thanks to the effect of relativistic time dilation. When you approach the speed of light, time slows down, so a trip that would otherwise take 500 years can be only 10 years for the passengers.

by Dismal-Witness-5780 1 year ago

You would need to be going ~99.978% the speed of light for this type of relativistic effect. This is impossible for a massive object. Protons can only reach 70-80% of the speed of light. At 10% (which is a goal for some very ambitious propulsion research companies), the time dilation would turn a 30 year trip (roughly getting to Alpha Centauri) into a 29.85 year trip.

That depends. If you're using a mathematically feasible warp drive method, this would not occur, because of the "normal" space the craft is suspended in. You're folding space, rather than simply moving an object through it.

by Jeanprosacco 1 year ago

Where do you get the idea protons can only reach 70-80% of the speed of light? This is completely incorrect.

by Anonymous 1 year ago

Protons are accelerated to 99.9999991% the speed of light in the LHC at CERN, right now here on earth. Protons that constantly hit earth from outer space can also have velocities up to around 99.6% the speed of light. Now, accelerating a space ship is another matter, but you are factually incorrect about protons.

by Neither_Succotash_98 1 year ago

At 10% of speed of light, it would take 50 years to travel to Alpha Centauri. Provided you would need time to accelerate and slow down, that would become around 70 years or so. Still within one lifetime. And, the funny thing is, we already have the technology and means to make that happen. There simply is no will as this is a very, very expensive enterprise for any one country.

It's not about the astronaut. 500 years is 500 years to the rest of the world. Think about how much has changed since 1524, and then imagine how little the world would care about the reports of an astronaut 1000 years from now (the signal would have to travel back to earth). The world we know won't exist in 1000 years. Interstellar travel is an absurd pipe dream.

by Anonymous 1 year ago

You are correct. That being said, the closest exo planet to us (Proxima Centauri b) is only about 4 light years away.

by Anonymous 1 year ago

It's one Earth year to people not traveling at the speed of light. To the photons traveling at light speed, no time passes. To someone traveling at 99% the speed of light, about 3.58 years will have passed. To the people on Earth, 500 years will have passed.

It would still take you 500 years in real time to get there though, assuming you don't hit some stray rock or mass that hits your ship like a high explosive due to the speed and immediately ends your voyage.

by sheagrady 1 year ago

500 years in Earth time. There is no universal "real" time.

by Anonymous 1 year ago

No, that's not how time dilation works. Ten light years is ten light years. As in, at the speed of light, it takes ten years to travel that distance. That's the rate for the person experiencing that trip. Time dilation would affect how long the trim appeared to take from an observer back on Earth's perspective, but what the would see is a trip that takes even longer than ten years.

by Anonymous 1 year ago

Ten light years is ten light years. As in, at the speed of light, it takes ten years to travel that distance. No. Just look at the equations for time dilation and length contraction in special relativity. For anything traveling at speed c, every trip is instantaneous in time for the moving observer. A distance of 10 light years for observers on Earth is length contracted to 0 for observers moving in a ship at speed c. 10 light years away means 10 years pass to get there from the perspective of observers at rest on Earth.

by SpinachMurky 1 year ago

Vastly different things

by Chaimhauck 1 year ago

That was mostly a technological problem of designing aircrafts capable of resisting the increased drag. Bullets and cannons were already breaking the sound barrier for a long time. The light speed limit is fundamental physics. We have never seen anything in the universe break that limit. Even the possibility of a particle faster than light was a big deal a while back. Sure, maybe what we know is wrong, but it would have to be wrong in a major way, which is unlikely.

by Chaimhauck 1 year ago

That's not really comparable tho. You see the universe isn't moving more as you said expanding. So thus it's not correct to say "light can't be the speed limit of the universe because the universe is expanding faster than light" because it's just expanding. This analogy was given to me in physics class I have gotten taller since birth the distance between my toes and nose has grown because I'm expanding not because my nose was moving away from my toes but because i was expanding vertically.

by North_Dark 1 year ago

If two things are moving away from each other at the speed of light, the distance between them is growing twice as fast as lightspeed. But neither object is actually breaking the speed limit. We haven't identified anything moving faster than light and probably never will, unless there's something seriously wrong with relativity.

by Interesting_Note_645 1 year ago

Even whips can break the speed of sound.

by Anonymous 1 year ago

Ya but say we could even do it. Like how does that solve interstellar travel to a bigger degree? You wouldnt be able to control the ship or react to anything at that speed. A piece of dust would vaporize the ship let alone an asteroid. Also you cant just start at light speed and end. It would take a long time to get up to light speed and a long time slowing down from there without killing everyone on board. Also light speed still takes years to get anywhere thats still sort of close outside of our system. So its not really even fast enough to make it function anyway.

by RegularKnowledge9408 1 year ago

Also, we have been breaking the sound barrier since the invention of the whip.

by Anonymous 1 year ago

There was never a physical law that forbids travel faster than sound, but there is for the speed of light. This law is also incredibly well tested. The only loophole (hahaha) would be a wormhole. At the moment there is no law of nature preventing that, the existence of those is purely theoretical though and our theorie is incomplete

by Pearlieratke 1 year ago

We are 3 dimensional beings in a higher dimensional universe.

by TraditionalKing4008 1 year ago

But there's a very, very miniscule chance that things can move faster than light. Take tachyons for example. As theoretical as they may be, the fact that physicists, such as Michio Kaku, haven't completely ruled out these theoretical, faster than light particles tells me that FTL travel/movement may not be as impossible as we used to think. And of course, even if they do exist, they're microscopic, and it would be a million times harder to do on a scale that we would need. I'm just saying that FTL movement may not be 100% in general

by Yschumm 1 year ago

For me the only plausible theory that holds even a slim chance of possibility for humans to ever harness is that some kind of wormhole might exist that can be harnessed. That alone is already pretty far fetched though.

It is not well tested. The universe itself already expands faster than light.

by Illustrious_Bill8957 1 year ago

The truth is that if interstellar travel is possible in theory then it's only a matter of engineering and a deeper understanding of physics to get there. As soon as physicists understand what space really is at its most basic form then it won't be long until people start creating the technology that can manipulate it and allow for FTL travel. It may not happen in any of our lifetimes, or in 1,000 years, but there are countless physicists trying to understand it and I believe at least one will have a testable and provable theory. There's just too many things we don't understand to rule out interstellar travel so early. We don't even understand what matter, time, energy, and space is at a fundamental level, we just know that they exist and we've created arbitrary ways to measure them.

by Anonymous 1 year ago

As someone studying physics there are few things to consider. There are methods of "moving" faster than the speed of light by instead moving the space you occupy. We don't know how to do it yet, but the math says it should be doable. There is a growing consensus that we have something seriously wrong with our understanding of the universe. There is plenty of room in physics for finding some way around the speed of light. We don't even know what 90% of the universe consists of.

by Anonymous 1 year ago

I agree. But consider this hypothesis for a moment. What if Einstein's theories relativity are wrong? What if the speed of light isn't in fact a universal constant?

by Anonymous 1 year ago

If the speed of light wasn't a constant then time dilation wouldn't exist, but it's been proven that time dilation exists so the speed of light is definitely a constant.

The speed of light changes depending on the medium it's travelling through.

By the speed of light I'm talking about the speed of causality, the speed of light just so happens to be the speed of causality. Which doesn't change depending on the medium it's in. I only said speed of light cuz that's the most common way to refer to that speed, but my point remains that it's a constant.

by Joshschiller 1 year ago

A counter point to this: is that so FAR we think we won't be able to… but what happens if we discover something that can actually surpass light speed? Light speed is only the speed limit of the universe because so far we have not been able to find anything that can travel faster than a photon. However the other thing about light traveling is that it also exsist in a wave function when traveling and that wave function only collapses when we view it (it's also why older light turns more red because of the changes of the frequency and pitch in the wave that have degraded over time) So theoretically what else is in the wave function that is also traveling at that speed? Also if light isn't traveling in a straight line but in a wave, with lots of ups and downs and backs and forths, does that mean photons are actually traveling "faster" than light speed? Similarly to how if you're driving, your car can be going one speed but if you move your hand forward your hand whilst moving forward is actually going faster than the speed the car is going (and slower if you move it backward). Basically stuff like this we don't really know the answer to and scientists might find out that photons within the wave function are traveling slightly faster than the speed of light and now we have two different speeds: the speed of a wave function and the speed of photons within a wave function.

by Anonymous 1 year ago

C is the speed of Causality first and foremost. Massless particles like photons, gluons and gravitational waves can only travel as fast the maximum speed of causality would allow. That is why mass exists in the first place, C has to be finite or there would be no mass and only particles wizzing around with infinite energy.

There is no waste of space because the universe doesn't have a meaning or a sense. How can you define what is wasted in the Universe? We are applying human values to something that simply doesn't have values. If other lives should exist, it is simply because of probability, not because of creating meaning.

Idk how the speed of light would be able to even be used. It would probably kill you accelerating to get there and if it didnt accelerate that fast it would feel like you were in a fighter jet pulling an absurd amount of gs for probably an insane amount of time as you keep speeding up at a slow enough rate to eventually get to that speed. Then when at that speed you cant see or react to anything and would probably almost immediately hit a rock or anything out there and be obliterated. Maybe once you make it out of the sol system theres nothing physical to hit until the next one? Im no expert. But going the speed of light from earth to mars and through the asteroid belt would be absurd and almost certain death

The thing with interstellar travel is that it's, imo, effectively useless for any practical purpose. It would be way more technologically feasible to construct advanced world ships or Sandy Tree Dome like environments and harvest space ice and asteroids for metals and resources then it would be to devise a means to achieve SOL or FTL travel. I do however think over the next few centuries we will make breakthroughs in propulsion that seem futuristic by todays standards. A perfected and highly efficient plasma thruster or nuclear propulsion would probably be able to get us to star systems like say, Alpha Centuri within a human lifetime. But traveling say, hundreds of light years to explore earth like exoplanets? Meh, doubt it, what resources do we need besides water and metals? All of those are found in near limitless quantities in our own local area, no real need to travel so far.

Think about it this way There is no such thing as free energy in our universe perpetual motion machines are impossible but only in this universe. The current laws of physics are valid with certainty in regard to only the universe they describe. There is some deeper framework that sets the laws of physics in our reality and of course the laws of that framework in an infinite reality matryoshka doll.
