Also, if you could travel to another star at near the speed of light, you could travel to another star within a life time as time is relative (the faster you travel towards the speed of light, the slower your time ticks). It would be feasible for some hyper advanced alien race capable of travelling close to the speed of light (I would love to know where they got the energy from to do that lol) they could travel to many stars within a single life time. But because there are hundreds of billions of stars in the milky way I find it unlikely that they come across other intelligent life very often (if at all). The milky way would require a lot of exploration.


How much time of Sun's irradiated energy would we need to get a few ships to, say, 0,9999c if we could keep it all?

At 0.9999c, it'd take awhile, likely.

But to get to 0.9c, it'd take a few seconds..If that.



Back from the dead, I'm afraid.

Phew. I wouldn't know I'm afraid. Erm, a lot, that's all I can say.

Going by E = mc²(1/V( 1 - v²/c²) - 1) it would land something like 4,5 x10^26 joules per kilo ton. It seems the Sun outputs around 3.86×1026 J/s. So it'd take a little over a second (supposing you could harness all of it's energy with no loss at all and perfectly convert all this anergy into aceleration, which is obviously incredibly far from realistic) to have enough energy to accelerate a kilo ton to 0,9999c.

My point is I think the source of energy isn't really the problem as much as the entire technology and logistics to make it work.

Edit: fun bit: it seems it would take over two thousand times as long as the universe has existed to get enough energy at the present rate the sun outputs it (sure it'd be long gone by then) to get the sun the earth and the moon up to that speed.

Probably not something to get overly excited about. Probably going to be something similar to what i've linked too below. Have my fingers crossed for something a bit more exciting though.

It depends on their ability to do harm or not.

But we wont really know that until after first contact will we

You really think the government would allow a direct contact with unknown life forms,without first studying if they are dangerous or not?

If the lifeforms are intelligent and more advance than us then I would question their ability to prevent hostility. Or maybe Ive just played too many video games that involve so form of alien invasion.

I'm afraid I'll find it hard to get excited. It'll probably just be some discussion on an organic molecule that they found on some other body in the solar system, or a discussion on new evidence that could point to liquid water on a moon somewhere. I don't think it'll be anything big.

I would love it to be life, but I think it's a discovery that we're not expecting to make at any time in the near future.

How long do you think will it be till we can contact other life? Meet them!

I really can't say, one thing I can say though is that we're certainly not on the trail of life.

Sure we can hypothesise about finding life in the oceans of Europa (or something similar), but we have no concrete evidence to point us to where we should be searching. There could be life there, but then again there may not. Right now astrobiologists have a "follow the water" policy, and whilst that may be good indicator it is little more than an educated guess.

In short, it could be within our lifetimes if life exists in our solar system, but I wouldn't count on it Intelligent life on the other hand, I think there's no chance within our lifetime I'm afraid.


Yeah, I gotta agree.  Unless someone comes to see us anyway.  Unless there is some big "space fold" discovery.

Crap, even then, the odds of finding life are VERY unlikely.


I remember either on the Next Generation or a show about it, explaining how crazy and impossible it would be to explore all of the space near us if we did it unguided.

Oh. My. God. If alien life really has been discovered, even if it's just micro-organisms, the universe as we know it might be fundamentally changed after this. This is beyond huge.

 


Not really, life elsewhere in the universe is pretty much a given to anyone with a rational view of the universe.

it is not a given, it is far from being 100% sure

it is just a strong possibility

Us being the sole form of life in the entire universe, makes us nothing more than an anomaly. Therefore, extraterrestrial life is a given. Simple math.

nah, you can turn it how you want, life somewhere on the universe is "only" highly probable.

but it is neither obvious, neithere sure, neither proven. We may, indeed, be this anomaly you are mentionning ...

Also, the way you are "thinking" remember me those guys that, because universe or life seems so complex and so well organized, consider the existence of god is ... a given ...

what do you think ?

At least millions of planets identical to ours throughout the whole universe, why no other life form? Why just us humans?

On your second point, on the contrary I am an Atheist. I believe the sole reason no other life forms can would be the existence of a God, him creating only us.

If we go by math, there's a 99,999999...% possibility we're not alone. That's a 100% to me.

Well, I mostly agree with you. And I agree with your interesting view about GoD creating "only" us.

It is just that ... there is perhaps nothing "living" to be found outside earth ...

Also, just to complement your point : you mention "planets identical to ours". I dont see why those "others" type of life should function like "our" type of life. So, to me, life could exist on planet pretty different from our one and not only on the "identical" ones
