Yes, or visit places where Spacetime is radically distorted by mass.

So I did the math. If we take a spaceship that’s moving as fast as Voyager is going (38,610 mph) and make it go 1000 times faster lol (about 39 million MPH) then we’d have a craft that can go about 6% the speed of light. Now you’re getting places! At that rate, we could reach the nearest star in only 82 years. (my math could be wrong, Im not an astro physicist. The speed of light is 186,000 miles a second if Im not mistaken…)

That’s just the nearest star, so exploring the closest dozen or so would take us about a Millennium. LOL. This is why I always say, the biggest Fermi Filter is simply DISTANCE. People have no f~~~ing idea how implausible star travel is. You either need cryo-sleep tubes which are impossible and it doesnt solve the time problem at all… or you need to build Generational Ships which, Im not getting on a ship knowing full well that I will die in transit along with the next 40 generations of my ancestors…

Interstellar Travel is a pipedream. It’s almost like stars are deliberately out of reach from eachother. LOL. I know you Christians love that kind of talk but I dont believe its deliberate, its just the way it is.

Yep, when it takes about a year just to get a man to Mars, we’re a long way from achieving speeds that would even get us out of our own solar system. Creating a usable time dilation with speed is something we will never achieve.

Not sure what you mean by “……Christians loving the idea that stars may be deliberately out of reach…….”…… I believe God had a purpose for where He put them, but at the same time, I’m also inclined to believe that He just scattered them and that’s where they ended up.

Space is so enormous, we can’t even comprehend. The fact that we can actually see those stars which are so very far away is incredible. I’m even fascinated that we can see Mars with the naked eye and it’s 140 million miles away on average. That’s a long damn distance and we can see the reflected sunlight from the surface of Mars.

Certainly not with anything similar to the propulsion engines we use today. And it’s not just building the engine, but find a fuel that has a mass/energy ratio that could possibly work and figuring out how to keep a human alive while accelerating to those speeds.

To me it seems more likely that we will develop wormhole tech, or some sort of way to slip in and out of yet unknown dimension before we figure out how to travel over great distances in normal space.

Ok. Then do it.

Over 40 years the Voyager spacecraft have been traveling and just recently one of them have gone far enough to actually be considered interstellar. 40 years to leave the solar system……… There’s a lot of space out there.

You’re definitely right about the fuel. It and the engine will need to be very efficient. I wonder how much matter/antimatter and how many dilithium crystals the Enterprise goes through in a month.

call me crazy, but there are lot of books that say technologies for space travel is already here, locked up in secret black programs.

propulsion systems like tachyons (sp?) and such. If anybody is interested in reading these things, I can recommend couple of books. Of course, you have to have an open mind.

I told ya’ll I would get back with some sources on time travel. Minuscule, but proves it is possible.

Clocks were found to disagree with one another
NASA Hafele–Keating experiment
Synopsis:
The Hafele–Keating experiment was a test of the theory of relativity. In October 1971, Joseph C. Hafele, a physicist, and Richard E. Keating, an astronomer, took four cesium-beam atomic clocks aboard commercial airliners. They flew twice around the world, first eastward, then westward, and compared the clocks against others that remained at the United States Naval Observatory. When reunited, the three sets of clocks were found to disagree with one another, and their differences were consistent with the predictions of special and general relativity.

Time dilation
Twin paradox
Synopsis:
Time dilation has been verified experimentally by precise measurements of atomic clocks flown in aircraft and satellites. For example, gravitational time dilation and special relativity together have been used to explain the Hafele–Keating experiment.[A 1][A 2] It was also confirmed in particle accelerators by measuring the time dilation of circulating particle beams.

TIme Dilation
Synopsis:
According to the theory of relativity, time dilation is a difference in the elapsed time measured by two observers, either due to a velocity difference relative to each other, or by being differently situated relative to a gravitational field. As a result of the nature of spacetime, a clock that is moving relative to an observer will be measured to tick slower than a clock that is at rest in the observer’s own frame of reference. A clock that is under the influence of a stronger gravitational field than an observer’s will also be measured to tick slower than the observer’s own clock.

Such time dilation has been repeatedly demonstrated, for instance by small disparities in a pair of atomic clocks after one of them is sent on a space trip, or by clocks on the Space Shuttle running slightly slower than reference clocks on Earth, or clocks on GPS and Galileo satellites running slightly faster. Time dilation has also been the subject of science fiction works, as it technically provides the means for forward time travel.

ENGINES for Space Travel.

ION DRIVE
Synopsis
An ion thruster or ion drive is a form of electric propulsion used for spacecraft propulsion. It creates thrust by accelerating positive ions with electricity. The term refers strictly to gridded electrostatic ion thrusters, and is often incorrectly loosely applied to all electric propulsion systems including electromagnetic plasma thrusters

HALL effect thruster
Synopsis:
Hall-effect thruster (HET) is a type of ion thruster in which the propellant is accelerated by an electric field. Hall-effect thrusters trap electrons in a magnetic field and then use the electrons to ionize propellant, efficiently accelerate the ions to produce thrust, and neutralize the ions in the plume. Hall-effect thrusters (based on the discovery by Edwin Hall) are sometimes referred to as Hall thrusters or Hall-current thrusters. Hall thrusters are often regarded as a moderate specific impulse (1,600 s) space propulsion technology. The Hall-effect thruster has benefited from considerable theoretical and experimental research since the 1960s.

STRAIGHT out’a RUSSIA BABY!

WEB link:

How long does it take to get to Mars with an ion drive?
There’s a growing chorus of calls to send astronauts to Mars rather than the moon, but critics point out that such trips would be long and gruelling, taking about six months to reach the Red Planet. But now, researchers are testing a powerful new ion engine that could one day shorten the journey to just 39 days.

Max speeds of Ion drives in Space?

200,000 MPH
Spacecraft powered by these thrusters can reach speeds up to 90,000 meters per second (over 200,000 mph). In comparison, the Space Shuttles can reach speeds around 18,000 mph. The trade-off for the high top speeds of ion thrusters is low thrust (or low acceleration).

You are all alone. If you have been falsely accused of RAPE, DV, PLEASE let all men know about the people who did this. http://register-her.net/web/guest/home

Yep, these thrusters seem like they could be rather useful for when you have to travel a long distance, but would be terrible for short distances and movements. It feels to me like it’s stop gap technology…something we need to get used to and understand better before figuring out something better.

Ok. Then do it.

MANY involve the alien presence on earth and who runs the world. Which is why I said, “open mind”.

If what they say is true, it would mean that a complete overhaul of everyday life in terms of travel, communication, flight, medicine and industry would be needed.

Lot of industries would disappear and mega trillions that go with it…around the world.

I’ve always liked to think that I have an open mind, but I reckon it may be a little too obtuse for this. LOL I’m not saying I don’t believe in non-terrestrial life. The galaxy alone is too huge for anyone to think we’re the only ones. I’m just not sure I can believe in aliens on Earth.

There is no shortage of accredited scientists who TALK about theoretical propulsion systems that could make Interstellar travel possible. Its all TALK…

It doesn’t take a mathematician to recognize PHYSICAL BARRIERS (as in physics) to travelling between stars.

Once you understand the objective framework, the notion becomes impossible. Wormholes are impossible to travel through. Be REAL.

Nano-SAIL bots can’t carry people and even if they could, there is no way to slow down when you get there.

FTL is impossible.

Stars are too far apart from eachother, as I said before:

That’s just the nearest star, so exploring the closest dozen or so would take us about a Millennium. (assuming we could create a spaceship that is 1000 times faster than Voyager and go 6% C, we CANT). This is why I always say, the biggest Fermi Filter is simply DISTANCE.

The ONLY WAY for flesh beings like us, and other sentient extra terrestrials, to travel to other stars is either Generational Ships or Cryo-Sleep. Cryo-Sleep is not possible for journeys over six months so that one is out. It KILLS you… Generational Ships are also a BIG improbability because there is no gas stations or grocery stores in interstellar space, not to mention a gross lack of sunlight and no air… We’re talking thousands of years in space just to hop to one star.

IN MY OPINION, we should be building GEN SHIPS NOW, by way of totalitarian governments. The end justifies the means. We’re literally one cataclysmic event from extinction. Just because we invented ipods and gas engines doesnt mean s~~~…just a fart in the wind. This species is still very primal and retarded. We need to colonize another world to prevent extinction. This project will take several millennia and we’re wasting precious time. If we get snuffed out, 1 billion years of valuable Natural Selection goes with it <— That is a Fermi Paradox Filter! All other hominids have snuffed it, we’re the last ones and we sort of owe it to them as they were here 20 times longer than us..

I think Issac Arther would agree with me to some extent. Love his channel, forgot about for a few months, glad I remembered to resub.

Time is a river you cannot reverse, speed up, or slow down.

Technically that is not true Hermit. While travelling Backwards in time is totally impossible, travelling forward in time is only a matter of velocity.
Time dilation. If I were to get in a Spaceship and haul ass out into space for a few years, then turn around and head straight back at that same fast speed, 6 years would have elapsed for me on my spaceship but Earth time would be 20-30 years in the future. Id of essentially traveled forward in time. Everyone I know would be decades older but I would only have aged a little.
The faster you go, the longer you live.

Uh… how do you figure?

[Gravel PitParticipant]

The faster you go, the more Mass you have.

The more Mass you have, the more you curve Spacetime.

This causes a discrepancy in the passage of time between you and observers.

If I leave Earth at say 80% the speed of light. And travel for a few years and come back. My on-board calendar is not going to be in-sync with my brother’s calendar on Earth. Time will have passed more slowly for me compared to him. If I were the older brother, I might now be the younger one. Try to understand that one! LOL. Only kidding.

We see an example of this in Interstellar when Cooper travels near a blackhole (which is actively swallowing two stars). The blackhole distorts spacetime so much so that travelling near it slowed time when compared to Earth’s.

As a result, they we thrusted into the future. So I say that time travel is possible, just not in the direction we’d prefer. Travelling backward in time would be possible if we could somehow transport or materialize hundreds of lightyears away but that is impossible. The fact that we have to travel to get places, makes backwards timetravel impossible.

Again, I believe no time travel is possible. Time dilation is not the same as time travel. You cannot travel to a future that does not yet exist. IF, you could travel fast enough to significantly slow time down for you so that when you return the normal passage of time has aged everyone and everything naturally, you have not really traveled through time into the future. You’ve only distorted the passage of time for yourself while waiting for natural time to progress normally.

Besides, as I had posted earlier, we’ve only observed time dilation on a very miniscule scale in fractions of a second. We do not have to means to achieve the speeds necessary for practical use.

Yeah, I guess it’s not “time travel” per sey… it’s just hanging out next to a black hole so you can out live everyone you know. Not like a TARDIS in Dr. Who.

I’ve always greatly enjoyed any movie that involved time travel, even “Back To The Future”, but it could never actually be possible. You can’t go back, the past is gone. You can’t go forward, you just have to wait. Living in now is difficult enough sometimes. All we can do is make the best of it.

Did you ever see the movie, “The Langoliers”? In spite of it being scientifically stupid, I thought it was an entertaining movie with a premise loosely based on time travel, or actually how time travel is not possible. If you haven’t seen it, I don’t want to ruin it for you, so spoiler warning. Some of the passengers on an aircraft somehow get a few hours out of sink with time and are left back in a void where “creatures” eventually come and eat up everything left over in the past.

My only point in mentioning the movie is to illustrate how there is no past to travel to and therefore there cannot be a future to travel to either. Time moves in one direction only, no matter what. If time travel were possible, you’d have to consider that going back in time would be more plausible than future travel simply because at least there might be “something left over” since we had experienced it before. Nonsense, yes, but it’s all nonsense.

You can’t travel through time. You can’t move time. You can’t speed it up or slow it down, at least not really worth mentioning, as any observations of time dilation have been in the nanoseconds only. Our physical existence won’t allow it. As you know, I believe in a spiritual existence so if time travel is possible, it may be so on a spiritual plane.

[Gravel PitParticipant]

I agree with you Hermit. Im a realist when it comes to Intersteller travel (that its too far fetched to accomplish). So reaching velocities capable of distorting time is off the table and also travelling to naturally occurring massive objects that will also distort time, that is also off the table. So we’re agreed, Time Travel to humans is strictly Sci-Fiction.

I haven’t seen that film but will have to check it out. There have been numerous films since films began filming lol, that feature Time Travel. Some are blockbusters or fancy Indie one-offs… others are total flops.

Primer was a really great indie film, low budget which was excellent time travel film.

Timecrimes is also another good one, its in Spanish but well worth reading the subtitles.

There are MANY.

Who on Earth hasn’t watched The Time Machine and absolutely LOVED it?! (people with no class or taste LOL)
