When will we reach the Moon, Mars, Jupiter, another star and another galaxy...

Again even if such species existed. You still have to think of time periods. Even if they survived 10 million years that still not a very good chance of being in the same period as our 160k

Its a chance but a slim one.

The problem is science is lacking scientist like Einstein, Newton, Edison, bell, etc
that helped the world advance by leaps and bounds in physics, chemistry, mathematics and other fields.

I don't think we have that now, I could be wrong.


Atm we got x factor, Justin Bieber, these are the names that are popping off now

We do, plenty of them about.
Michio Kaku
Hawkins

Are probably the two most famous. It's just we don't hear about them and barely here the theories. Plenty working on cutting edge stuff, including things like string theory.

wHel don't you think that given the amount of planets out there one of them hosts intelligent life species? I think many planets have many life forms all at a different stages of progress of evolution. I think there are intelligent life forms in the universe right now. Hmm thinking about it...let me get my tinfoil hat on...all right ready, thinking about it if chances are some life form is very very advanced wouldn't they have already invented intergalactic travel by now and shouldn't they have visited us by now? Perhaps they did and all the looney conspiracies are true?! Oh dear I better take the hat off and go to sleep.
 
Do I think it likely of course, have we Confirmed even small organisms. No.

Seem to of ignore the time problem as well the universe is billions of years old, you could have thousands of advance species and they could miss each other by millions of years. Let alone distances to some of the far away galaxies.

We simply have no idea how abundant or scarce life is.

everyone knows them though. We are not abundant with revolutionary scientist trying to change the world.

:confused: what a odd comment especially as you posted so few scientists, as I said we don't remember names, but there's loads going on.

LHC, at least two different approaches to fusion, string and many many other theories, about twenty or more space propulsions or under different levels of development, most at least lab tested.

We can't exactly confirm or deny even bacterial life on planets as we don't have the technology to do so.

We can't see what's on the surface of a planet billions years away but it might as well have a thriving civilization right now.

But I am thinking given the universe as far as we understand has been around for 14 billions of years and the amount of planets and galaxies the chances are life form on other plants does exist and chances are its fairly evolved and intelligent. It took us around 4billions to get from simple cells to what we are right now.

That's the problem. I don't they are getting their due credit for their efforts

We never have, nothingS changed. We will remember them when there Theroies are proved or massive break throughs. But even then we might not hear about them like in the past as they aren't life changing to normal people. Also where one person could change the world, things are so complicated it now takes hundreds to research anything these days.

I find it highly unlikely to be a probe due to time dilation. It would IMO be a colonisation mission, after successful colonisation of other star systems in our galaxy. What is the point of sending a probe when it would take so long to find anything out. Humans on the other hand by that point would have spread itself over a sizeable chunk of the milky way and have more than enough experience. Wet ere that would be 300 years or 10000.

To another star would make more sense for a probe as it can be done at a speed time dilation isn't a factor.

Let's keep the eye on the ball here. The proposition was ANOTHER GALAXY! TWO-HUNDRED AND FIFTY YEARS! <--- REALLY!
 
AcidHell2 said:
But you also said it was impossible due to travel time, which it isn't.
Click to expand...

It is, when you measure it in anyway that really matters... ie: OUR frame of reference, as the OP basically asked for... So, ANOTHER galaxy, in 250 years? <-- REALLY?
 
AcidHell2 said:
That is not and never has been the correct time frame, but if you what to measure it from that no it's not possible. But the only useful time frame, is flight time.
Click to expand...

Why is it not the correct time frame? How is the only useful time frame the flight time? What nonsense?

We send a probe to our nearest star to determine if it can support life. If it takes 10yrs to get there, and for the data to get back to us, why is the flight time (of 1 second or 5 years) the slightest bit relevent? It's ten years till we get the thumbs up!

What time frame is important depends entirely on the question at hand. In the context of this thread it's the fairly predictable and uniform time here on earth...
 
Becuase time frame from earth makes everything pointless. The only timeframe that is useful is the actual travel time and hapow far a human or generation ship could go.

To nearest star, yes time unearth is the relevant one, because we don't need 99.99% of speed of light, there for no real time dilation. The mission will also be different Diego a reasonably short time frame, meaning probes make sense. when you start talking 100ly then only travel times important and sending probes is pointless.

Nonsense, it depends on the question.

Read my previous example again, what does it matter if that probe took 1 second or 5 years in relative time, if here on earth 10 years pass by before its data gets back?

You're fixated on time dilation... Again, the OP didn't aim to be that way inclinded...

For 5 years, Nothing, as I said it depends on distance and mission. When you start talking about distances to other galaxies. Then time on earth becomes totally irrelevant, it won't bea roundtrip, it won't be a probe. It will be for colonisation.

I'm on fixated on time dilation when we get to huge dpdistances as this instantly changes the type of mission that can be made. Your original problem was with another galaxy and at which point time dilation is very relevant indeed. Are you going to send a probe when it will take at least 25000 years or 2million years if we don't want to go to a dwarf galaxy. What would be the point of that.

So you stand by the suggestion that we'll most likely be in another galaxy in 250 years of relative time then? You think this is a realistic and probable suggestion?

I don't think we'll ever get to another galaxy, unless we figure out some God like abilities to go through worm holes. And I don't believe we'll ever do that...


If interstaller travel ever proves viable, then I think we'll hit the universes speed limit of a high fraction of the speed of light, and the next issue will be the will and resources to get to other systems... But I recon it will be a very arduous and slow process with a minefield of problems.

But I wouldn't be surprised if there are fundamental reasons why even high speed interstellar travel proves impossible... Or at least for so long that we literally use up all resources on this world and are left marooned.

We may never have a manned mission to another star...
