Time may be a great healer, but it turns out it can’t heal all wounds. Take the great Titanic / Door debate, for example.

It’s been twenty years since Jack was unceremoniously left to die in the north Atlantic by Rose, and the world still refuses to except she had no other choice.

Director James Cameron may have waded in with a spirited defence of her actions, but, two decades later, fans still remain unmoved: Kate Winslet’s character has blood on her hands (and even Winslet agrees ).

To end the debate once and for all, however, what we really need is scientific proof that Jack could have somehow survived, reports the Mirror.

And now we have it - thanks to a group of school girls.

An award-winning group of year 10 pupils from Westminster School, Adelaide, came up with a maths formula which shows how the ill-fated lovers could have BOTH survived - with a bit of team work.

The brains behind the formula, Abigail Wicks, Christy Zhang and Julia Damato demonstrated how Jack and Rose could have both stayed on the door if they’d put their life jackets underneath to make it stay afloat.

As with so many of us, Christy, 16, had come away from watching the film wondering if Jack had in fact had a shot at living, reports Adelaide Now .

This gave her the idea for the project.

The group last month took out the Year 10 section of the National Maths Talent Quest, in recognition of its discovery.

‘We looked at how buoyant the door would have been, and how that would have changed if there were people on top of that,’ Abigail, 15, says.

‘There was a lot of exploring and testing, and we had to fiddle with different buoyancies and look at what materials were realistic for that time.’

Julia, 15, added the team had to factor in how the water’s salt content would have impacted the door’s buoyancy - and the result of bad news for ‘Team Rose’ fans.

Girls, thank you.
