I think you're confusing what made life on Earth possible rather than what is possible under other worldly circumstances. For instance, in theory water is not completely essential for life. If a planet has an incredible amount of methane, they could use it as the base for their bodies rather than water. Sure it would help to have an Earth like environment, but to say its essential is just silly because of how little we actually know.



No, I'm citing what most scientist all agree is required for any plant to be stable enough to first see life emerge and then evolve.

As for your example of methane it would actually be a poor substitute for water due to the fact that methane is a poor organic solvent compared to water. Basically, organic compounds in a methane sea would not break down and mix together and thus the basic building blocks of life would never be brought together. It's the solvent properties of liquid water that makes it so vital in the creation of life, not just the fact it is found in liquid form here on Earth.

you obviously know your stuff and i am not at all that informed in physics, astronomy, etc but isn't there an idea out there that suggests that because of time dilation that when one were to travel the speed of light they themselves would only feel a fraction of the time that those on earth would? or whatever gravitational force is influencing time


Yes. One would also have to become light in order to travel at the speed of light. I can wrap my mind around many unbelievable things but I cannot accept things that defy logic and reason. If you become light you are not going to take human form again.

Scientists estimate 6 percent of the 75 billion red dwarf stars may have Earth-size planets orbiting them at a possible habitable distance. That works out to approximately 4.5 billion Earths out there.


The real question is: How many have OT Ballers living on them?

oh yea, i totally understand that bevy of reasons why traveling at the speed of light is impossible i was just curious if i wasn't making up theories

I don't care about visiting other planets because I think you guys are right about the distances involved are much more then anything that could ever be built. I think Terraforming mars is an actual option that could be accomplished.

The only thing I really want to see in my lifetime is some type of proof that life exist on other planets because I believe it does. Hopefully in my lifetime we will have space telescopes strong enough to peer into the planets and establish if there is life or not. I don't even care if its intelligent life. I just want evidence that we found a place and i will be satisfied.

Voyager has been going for nearly 40 years and its barely on the edge of our solar system. We need to either develop some really badass technology that could get us there within one or two lifetimes.


I disagree that we need to develop a technology to get us there in 1 or 2 lifetimes. What we need is technology that will sustain life in space so that a group of settlers (a 1000 or so) can sustain life, reproduce for generations and generations, many of them only knowing life on the space craft before they die, until finally, thousands of years after their initial launch from Earth, they make it to Earth 2. Hopefully constant radio contact could be maintained in some fashion.

Although, developing technology to get us there before one or two generations would be preferable.

I agree but I am not sure of the purpose it would serve as the sun will one day destroy both our Earth and Mars. If we want our species to last we must leave this Solar System and I don't believe that is possible. In all likelihood our species will be destroyed by an outerspace missle of some sort long before the Sun gets us.

If you don't care if it's intelligent life or not, I'm fairly certain scientists have discovered living organisms, such as bacteria, on other planets and celestial bodies within our own solar system.

It will be a great deal more than thousands of years.

Exactly. Let's take the "Earth-like" planet sitting 14 light years away as an example since it is about the closest one we know of. Were we to try and leave this planet and go there, we'd need a craft capable of sustaining speeds of over 50,000 mph for something like 2.3 billion years. And forget solar power for use as a power source as once we reach the outer limits of our solar system we will be too far from our own star to harness it's power. This craft will have to be self sustaining in every way for literally billions of years. And even nuclear power would not be enough seeing how there is no known nuclear fissionable material with a half life measured in the billions of years. Simply put, we'd run out of gas before we got anywhere close to this seemingly close planet only 14 light years away.

There would also be the issue of enough water for the trip as you cannot simply stop on the way and get more. This craft would have to be able to hold enough water for however many people were to take part in this multi-billion year voyage. It boggles the mind to try to comprehend what it would require for such an attempt.

4.5 billion Earths?

The Earth is also 4.5 billion years old.

There are enough Earth's for every Earth year Earth has been Earth.

We are living in a simulation.

All correct. I think humans are stuck in this solar system for good.

re: Kepler Space Telescope Data Reveals Billions Of Earth-Like Planets Near Earth


Your thoughts on warp drive are, in my opinion, wrong. One day, we will achieve it because we have already theoretically determined a feasible model. The real issues are A) the power source powerful enough to give us the energy necessary to achieve it and B) the proper way to handle it without the destruction of everything in its path. One does not need to speed up to travel through the system at warp speed, but instead, it must compress distance traveled to safely cross it at a speed that wouldn't degrade the safety of the vessel. While it seems unlikely to happen anytime soon, I don't find it wholly impossible.

Centuries ago, it was not thought that one could fly, and the thought that leaving Earth was possible was probably considered heresy. As the last 20 years or so has shown us with the rise of the computer, the advancement of technology is exponential. Because of this, technology will be capable of such things before we are destroyed by an outside source, not including mass nuclear destruction through international conflict. The upcoming leap in technology through quantum computing, a field I'm studying to one day be a part of, has such an astronomical amount of potential that I feel like within a few decades, the idea that we understood what computing is capable of now will be laughed at. The potential gains are just that large. Because of that, I just can't see us not one day accomplishing that, albeit centuries from now.

Because we have no purpose. In the scope of Earth, we're important, unique snowflakes with our own intricacies. In the scope of the universe, we are irrelevant footnotes. The span of humanity's rise to dominance on Earth is like that of a minute percentage of the blink of an eye in relation to the universe.

Sad but true. Unless we discover some as yet undiscovered force that allows sustained travel at speeds faster than the speed of light (much faster in fact) and then also come up with a way to (1) harness this power and (2) build a craft capable of surviving such speeds and (3) some way to not kill any humans going that speed, we're basically stuck going no further than perhaps the inner edge of the Kuiper Belt.

re: Kepler Space Telescope Data Reveals Billions Of Earth-Like Planets Near Earth


The theoretical models don't try to use speed for all of those reasons. They try to shrink the distance. If I have to run a marathon at a sprint, I'd never make it. You ask me to run a lap at full sprint, though, and I'll do it with far less effort and doubt. That's the concept. It's a difficult thing to do, but it's possible. The power necessary is the real limitation.

NOT TRUE.

If you think about what the astronauts find in Rendezvous with Rama is a HUGE ship that is meant for inter-galaxy travel. If we don't want to die, we have to leave and need to build ships that can sustain travel for billions of years. Eventually, it will get somewhere.

Unfortunately, the average age range of a species is 3 million years, and we are at that and a little past it...so we're on borrowed time as is anyway.

And what exactly do you think we can use to compress space? The only force capable of affecting space/time is gravity. And the amount of gravity required to compress a space spanning light years would dwarf even the most massive black holes. Even if we could produce this much gravity, it would completely obliterate anything remotely close to it.

OK, what power source could sustain this ship for billions of years?

I'll answer your question with another question. How fast is our technology advancing since the microchip?

What makes you think we can't get something in a few hundred years that can answer that.


Right off the bat, I'd say fueling the ship by absorbing interstellar gas clouds that are full of ethanol.
