Nuclear fuel will last us for 4 billion years

Opposed to open pit mining which you need to get all the material to build solar panels which need constant replacement. Or the dead dinosaurs you need to dig up to burn in coal plants?

Do you have any understanding of modern nuclear reactors? Neither of those situations are a risk. The risk is old nuclear power plants that aren't being upgraded.

you have to do the same to build the nuclear plants...

that was not his point.

catastrophe wise its so far apart, i dont know how you miss it. chernobyl vs. people stuck in a mine.

30 years after Chernobyl, these Ukrainian babushkas are still living on toxic land

The 1986 Chernobyl nuclear disaster caused the permanent evacuation of 350,000 people. But a handful returned to the contaminated land near the plant, and 30 years later a few remain, outliving many of their neighbors who stayed away. A new film explores the power of home for "The Babushkas of...

Chernobyl's legacy 30 years on

The 1986 Chernobyl disaster contributed to the USSR's downfall, changed perceptions of nuclear energy and affects people in the region still to this day, writes Tom Burridge.

Oh I'm not talking here about you or me, but rather our descendants and their offspring. So yes, we need to start supporting and investing more into things like SpaceX. We are running out of time

Well it's unlikely we will ever get even remotely close to the speed of light we won't make it several million years in space either.

Space is a death trap, if radiation doesn't get you even just a little it is likely to end up sterilizing the first gen space travellers, then you will need artificial gravity it is a must, food, water, oxygen if any of the systems fail you are screwed. The size of the ship will likely need to be the size of earth it self to just accommodate all the system to keep people alive there isn't enough resources on earth to do that and it will need to be some thing that is build in orbit, you will need to start mining the outer solar system.

propulsion is another problem, even if you can get up to the speed of light it will still take millions of years, the human body nor the ship it self will withstand those forces even in zero gravity, however considering the size of the ship it will have its own gravitational field.

No matter how much technology and understanding of the universe improves the science will never be able to support it not in our life time not in a million life times.

The physical problems with interstellar travel is just too immense, just making it out of the solar system will be a feat in it self and we only recently managed to get to the outer solar system and not even completely out of it even and that took nearly 70 years.

While not impossible just improbable and will take several million generations to do it so you will need to deal with either negative or positive population growth not forgetting the several 100 thousand even millions needed to keep a ship like that in operation, even with automation things are going to break down and not be fixable.

just one stupid small mistake and your trip is over, you are just better off slapping rockets on the earth move people deep underground and launch the entire earth in the direction you want to go. lol It is fun to think off but the reality is much more sobering once you consider just how astronomical the problems are.

not pessimistic just a realist lol

Slap rockets onto earth hahaha that would be funny! Which forces would act on a ship if it slowly accelerates close to the speed of light in zero gravity?

And unless you invent a literal force field/shield like the one on Star Trek, you are going to be flying into all the millions of pieces of debris out there which will make for an extremely short and deadly trip. Especially if you are travelling at any decent speeds.

Well with a ship that size you will have artificial gravity, so the g forces would be insane, even at half the speed of light would probably be enough to liquefy the human body even if you need that much. can't remember the exact science behind it, but not dampening the forces experienced will kill quickly the closer you travel to the speed of light the more mass you have the more energy you need to expend the more mass you will gain whether with or without gravity isnt good the vibration of wave lengths and those interactions isn't good either.

either way you will never move faster then the speed of light or close to it unless you can solve the problem of gaining mass while travelling at those speeds whether with or without gravity.

Basically imagine you are in space inside a empty can there is no appreciable gravity however as you move closer to the speed of light the more mass the can will gain creating artificial gravity these gravitational forces will give you more mass and you will probably as a result be pulled to the middle of the can and be squashed into a little ball and eventually as the mass increases the closer you move to speed of light be squashed into a little puddle of nothingness, so whether you have gravity at the start or not you will eventually gain so much mass you will die.Whether you slowly increase to the speed of light or instantly the faster you travel the more energy you need to expend and mass you will gain.

tldr: special theory of relatively says you are screwed should you ever wish you travel at the speed of light or faster without countering the forces. Essentially you will need to cancel out gravity entirely and that isn't possible, basically the science behind the big ship in the interstellar movie.Take gravity out of the equation, if you don't have gravity you won't gain mass and you won't need to expend energy you will need to break or bend the special theory of relatively.

Its been done before, movie wise. Its called "the wandering earth", movie had some realistic science applied (with some plot armour for story telling sake) and subs were pretty good translation wise.

yeah I have seen that movie, earth engines or something, completely impractical to say the least, and not nearly accurate you would have to stop earths rotation and slowly instant stop would be like hitting a brick wall at 2200km an hour you would pretty much fly off into the atmosphere before coming crashing down again.

Once you slow down and stopped rotation temperatures on the dark side would plummet quite possibly below freezing with in a matter of days or weeks and the light side increase close to boiling, while you make your way out the solar system the sun will constantly bake the light side and the dark side get progressively colder. you will need to shield the atmosphere from escaping oceans boiling away as a result of that we will lose the moon and the molten core will eventually stop spinning and start cooling down, because as mentioned already you physical move an object like that at the speed of light even underground people would only survive for a couple of thousand years as the core cool down.

Even at the destination you would have no way of spinning the earth up again and restart the core spinning and the lunar tidal waves act, act, some interesting ideas but nothing scientifically solid. lol Movie had cool special effects and a lot of effort went into it I saw the dub.

The human element can and IS being removed through automation. Something that was not possible with the old plants because computers were not capable of it. Today it is a different ball game entirely.

One of the only true reasons for pursuing automation technologies.

Not a nuclear explosion.

Try again? 3rd time's the charm

 

[wizardofid]

Lol that was a core meltdown, due to lack of water, problem is you can't cool down the reactor again or introduce water as the core is extremely hot and adding water will instantly turn the water into a extremely hot gaseous state which means that gas has to go some where, the rapid expansion of the gas is what causes the explosion in other words a none nuclear explosion.

Consider nuclear material found naturally in earth never explodes even being under immense pressure and heat.
It requires specific actions and conditions do so and none of those conditions have ever been met since since the formation of the earth 4.5 billion years ago, and never will, nuclear fission is extremely difficult which is why nuclear bombs are extremely wasteful only a handful of material in a nuclear bomb actually has a fission reaction.

However while both nuclear bombs and a nuclear plant have nuclear fission in common, there are differences for example nuclear bombs compact the fissionable material as where in a uranium core rod isn't compacted the casing, the rods even water slow down the neutron reaction with the uranium nucleus, in a controlled chain reaction you will never get a nuclear bomb type fission reaction as the fuel rods have been designed as such which simply doesn't allow for a runaway fission reaction like that.

In order to have a nuclear bomb explosion requires quite specific configurations of fission material and actions and conditions has to be met exactly to the letter to have a fission reaction of as much of the material you can in one go.

The uranium fuel rods has been designed exactly the opposite of a nuclear bomb you will never be able to get same fission reaction even in the event of a core meltdown, even blowing up a nuclear plant.

Chernobyl explosion was a result of steam.

Yes a space elevator to low earth orbit is likely some thing we will see in future it is actually one of the less science fiction options we will use. It still has a few complex issues that need to be resolved and worked out, we are quite capable of doing it right now the issue is resources and money, it would bankrupt any nation that attempts it, it is more an issue of economics then science.It is actually pretty low tech.

 

[zippy]

“power all of humanity” Such a naive statement that doesn’t take into account the economics, and is disrespectful to the billions living in poverty who are unfortunate enough to not have access to this exclusive club called “humanity” who can benefit from nuclear power or any power generation for that matter

Typical dehumanisation of those who are “different” in terms of wealth and the other obvious things
