Time Trip – BBC Horizon

Time Trip - BBC Horizon

A thrilling journey deep into the strangeness of cutting-edge physics – a place where beautiful, baffling ideas are sometimes indistinguishable from the utterly crazy. On this journey, we meet a time-travelling pizza, a brilliant mathematician in a ski mask and even God. The journey ends with a strange and dark conclusion – one which calls into question our very existence. Ever since Einstein showed it was theoretically possible, the quest to travel through time has drawn eccentric amateurs and brilliant scientists in almost equal numbers. The amateurs include Aage Nost, who demonstrates his time machine in front of the cameras. The professionals include the likes of Professor Frank Tipler of Tulane University. His time machine sounds good – but it would weigh half the mass of the galaxy. There is, however, one way that time travel to the past could be possible. And it would be much more convenient. Future civilisations could use computers to create exact replicas of the past. Unfortunately that idea has physics trembling in its socks. Because if you can generate a perfect virtual reality version of the past, who’s to say we are not one of the replicas?

    So who really knows what Einstein truly believed, he often spoke of a god but made efforts to clarify that he didn’t mean for it to be taken literally. Either way, religious debate in channels about science only result in heated arguments that grow into epic proportions and clog the comment sections, that’s all I was pointing out and hoping it wouldnt happen here.

  2. lmos26 says:

    Or ” It was, of course, a lie what you read about my religious convictions, a lie which is being systematically repeated. I do not believe in a personal God and I have never denied this but have expressed it clearly. If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it”

  3. lmos26 says:

    Einstein said a lot of different things about religion, including ” The word God is for me nothing more than the expression and product of human weaknesses, the Bible a collection of honourable, but still primitive legends which are nevertheless pretty childish. No interpretation no matter how subtle can (for me) change this.

    @lmos26 Yes, u r surely welcome to keep ur religion n faith to u, n I have no intention to attack ur faith and beliefs, its just, Einstein said that “”Science without religion is lame. Religion without science is blind.” I’m a follower of Einstein n he’s my idol. So, on the basis of his statement, I said whatever u read.

  5. lmos26 says:

    @ProttoyEinstein and believe me, I understand more than most that people use the word God very loosely, as did Einstein “since ur name reminded me of it” so plz don’t think I am attacking you. I am merely hoping to keep religion and anti-religion hooting from starting here. I know what you said probably wasnt meant to be taken literally, but others may and do “jump the gun”

  6. lmos26 says:

    @ProttoyEinstein Aww, please don’t get ppl started on god here “if that was ur true intention” your last sentence is all it takes to start the fire and you know it. Its almost impossible to find a science video nowadays on youtube that isnt chock of religious argument. I am atheist personally but I go out of my way to keep that to myself, I don’t go into religious based channels and post about atheism for example, people are just too high strung on the subject.

  7. ProttoyEinstein says:

    Are we real is the fundamental question of physics from now on because if we are not real our set of understanding including the laws of physics which had been governing us for a long time might be altered in billionth of a second without us knowing! Surely GOD is the greatest!

    Thanks for posting. Please post Everything and Nothing (the “Nothing” episode if you can) cheers!
