What does it take to make one? The technology we need to manipulate a wormhole may seem impossibly remote. ibid.
While warp-drive is mostly science fiction at present there is some physics behind it ... Not all the sceptics are writing off warp-drives completely ... Another point: achieving warp-drive is very difficult. And control is a real problem. ibid.
The astronauts would have to overcome the problem of killer acceleration. ibid.
It’s woven into the very fabric of the cosmos: Time. The relentless flow of Time has driven the evolution of the universe and created many extraordinary wonders. These wonders take us from the very first moments in the life of the universe to its eventual end. Brian Cox, Wonders of the Universe 1/4: Destiny, BBC 2011
It takes two hundred and fifty million years to make just one circuit of the Milky Way. In the entire history of the human race we’ve travelled less than a tenth of one percent of that orbit. ibid.
Events always happen in the same order. They are never jumbled up and they never go backwards ... It is called the Arrow of Time. ibid.
Everything is irreversibly changing. ibid.
Why is there an Arrow of Time at all? We all have an intuitive understanding of the Arrow of Time. ibid.
The second law of thermodynamics ... Entropy ... Entropy always increases because it is always more likely. ibid.

Time, as the Doctor knows, is the key to exploration. ibid.
We’re all time-travellers in our own small way. ibid.

Like it or not we’ve all been shot relentlessly forward. Morgan’s Freeman’s Through the Wormhole s1e3: Is Time Travel Possible? Science 2010
Gravity slows time, and this is key to one form of time travel. ibid.
Time travel into the future is possible, but is it a one-way trip? ibid.
Einstein realised that time is relative to where you are and how fast you are moving. Time is the fourth dimension. ibid.
The universe does not rotate. And without the rotation you cannot have time travel. [Kurt] Godel’s solution was unrealistic but his radical thinking inspired a new generation of explorers. ibid.
Black holes ... Could the secrets of time travel lurk in their Stygian depths? ibid.
No-one knows if cosmic strings are real, but some physicists think they are out there. ibid.
Some believe that quantum non-locality can be used to send messages back in time. ibid.
Many quantum scientists believe there are an incalculable number of parallel universes. ibid.
We can’t turn back the clock. But we will keep trying. ibid.
It’s all around us but is it what we think it is? Time seems to flow forward but can it run backwards? Do events unfold one after another or do past, present and future exist side by side? Morgan Freeman’s Through the Wormhole s2e3: Does Time Really Exist?
Could it be that the future is already here? ibid.
The older we get, the faster the currents of time seem to carry us along. ibid.
Conclusive proof that the laws of physics change over time would settle the debate over whether time is real or an illusion. ibid.
If time wasn’t born in our minds, then where did it come from? ibid.
Eternity: it’s an idea as old as religion. Perhaps as old as mankind ... Will the universe end in a cosmic apocalypse? Morgan Freeman’s Through the Wormhole s3e9: Will Eternity End?
We imagine the universe too must have its timeline. ibid.
All of eternity might already exist. ibid.
Perhaps the dimension of time is just a holographic projection. ibid.
Before the Big Band there is no information in the universe. ibid.
Some questions require more knowledge than we could ever get. ibid.
We all float along the River of Time? But does that river have a source? How was Time unleashed? Morgan Freeman’s Through the Wormhole s5e1: When Did Time Begin?
Time is a measure of change: but how did we know things change? ibid.
It doesn’t really exist. ibid.
We’re all marching relentlessly forward through time ... What if we could send messages back in time? ... Can Time go backwards? Morgan Freeman’s Through the Wormhole s6e5: Can Time Go Backwards?

To every thing there is a season, and a time to every purpose under the heaven:
A time to be born, and a time to die; a time to plant, and a time to pluck up that which is planted;
A time to kill, and a time to heal; a time to break down, and a time to build up;
A time to weep, and a time to laugh; a time to mourn, and a time to dance;
A time to cast away stones, and a time to gather stones together; a time to embrace, and a time to refrain from embracing;
A time to get, and a time to lose; a time to keep, and a time to cast away;
A time to rend, and a time to sew; a time to keep silence, and a time to speak;
A time to love, and a time to hate; a time of war, and a time of peace. Ecclesiastes 3:1-8
For man also knoweth not his time: as the fishes that are taken in an evil net, and as the birds that are caught in the snare; so are the sons of men snared in an evil time, when it falleth suddenly upon them. Ecclesiastes 9:12
But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day. II Peter 3:8
We noticed on the green this huge wooden sign, varnished, highly polished, saying the Best-Kept Village of Bampton 1976 ... As we looked through the village [visiting the next day] everything had gone – the sign had gone, the flower bed had gone ... As we arrived in the village [the first time] we checked our watch and it was 7:30; as we left we checked the time again and it was still 7:30. Alf Roberts
In October 1979 Geoff Simpson and Len Gisby were driving through France on the way to Spain with their wives Pauline and Cynthia. They spend a night near Montelimar. Down the road from the Motel Ibis they found a guest house which seemed to belong to a by-gone age. At breakfast Cynthia noticed the other guests wearing clothes fashionable at the start of the century. The Gisbys and the Simpsons drove on into Spain. They’d never had a better holiday. Everywhere their cameras clicked. They brought back albums full of snaps but not a single shot of the French hotel. Both Len and Geoff took pictures there. When the films were processed, the hotel snaps had vanished without trace. And on the way back they could not even find the building. Had they stayed at a phantom hotel? ... Were they caught up in a time-slip? Arthur C Clarke’s Mysterious World of Powers
They [Gisbys & Simpson] were so impressed by the hotel they decided to stay there again on the way back to England. The next surprise came back in England when the two couples had their photos developed. The shock of the missing photographs spurred the Gisbys to carry out their own research. They discovered the Gendarme’s uniform and the dress worn by the woman dated from the 1900s. It’s almost as if the two couples had travelled back in time. But why did no-one comment on their car? And how did they pay the bill with modern money? Strange But True? s2e2, ITV 1995
With the modern currency he accepted it. And that was it. I mean it had always puzzled me. The only thing I can think of with all the dates corresponding is that we went into a time-lapse; we went back in Time. Len Gisby
‘I wish it need not have happened in my time,’ said Frodo.
‘So do I,’ said Gandalf, ‘and so do all who live to see such times. But that is not for them to decide. All we have to decide is what to do with the time that is given us.’ J R R Tolkien, The Fellowship of the Ring
