Prof. Brian Greene Shows You How to Time Travel!

Prof. Brian Greene, author of “The Elegant Universe” will show you the right way to time travel as he joins Faith in a discussion of the underlying science of time travel and clears up some time travel myths like, is it ok to interact with your younger self while time traveling? (Turns out, it’s OKAY.)

The day children start admiring scientists like they admire actors and artists, humanity wil take a big leap

That day is not so far, unless Humanity goes extinct before it.

[@al23438]

whats wrong with admiring artists? Without art and beauty there would not be a life worth living. Einstein once said “Life without playing music is inconceivable for me.” “I live my daydreams in music, I see my life in terms of music.” “If I were not a physicist I would probably be a musician.”

[@farisrafimeitaputra9178]

@@al23438 There's nothing wrong with how people admire artist. It's just people can't admire scientist as what they deserve, the knowledge they've been paving is immeasurable. If people admired scientists like how they admire artists, more and more people will have the desire to be a part in the search and development of knowledge.. and that's what matters.

@@al23438 You got it all wrong....

Conversely, if humanity highly valued scientists and under valued artists, the world would be a horribly boring place. But yes, science is currently undervalued.

I wonder how many lives I've inadvertently taken, or saved through the butterfly effect.. Stopping at a junction to allow a car to pass, that type of thing..

[@matthiasrandler669]

The Butterfly effect is always in effect. Try to picture this: You want to meet with a friend of yours. In the last minute your friend tells you over the telephone that the meeting is canceled. Now you stay at home for lunch, instead going out and eat somewhere on the fly. And because you eat at home, instead somewhere else, you use up your food a tiny bit faster as you would have otherwise. As a result you go shopping on monday morning, instead maybe on monday noon. And because you go in the morning you encounter different people in the supermarket. In the casshier line you have a lot more people as if you would have had on noon, so you wait longer there and maybe hold of some other guy for 5 minutes. That other guy now hits the road 5 minutes later and influences the traffic for someone else in a complete different way. You could spin this into endless outcomes, until you realize: You always change the whole of everything no matter what you do. If you sit silently in a cave for 30 years you effect the world just as much as if you would travel from place to place.

We are living in a multiverse and each of will live out our maximal life of 70+ years. When we are born, our consciousness is split across the multiverse and a small piece of it inhabits each copy of us in all of the universes that contain a copy of us. When you die in one universe, you wake up in one of the other universes in which you have made different choices and not yet died. This process continues until you finally end up in the last remaining universe that contains a copy of you. When you die there, it’s finally over. But knowing this is how it works - it’s foolish for any of us to not be saving for our retirement years. This phenomena is also the cause of what people refer to as the Mandela Effect
