    Could a warp drive work as a time machine?

    I'm sure you've heard of the warp/Alcubierre drive that would work by expanding space behind it and contracting it in front to achieve faster than light travel. I was thinking about this the other day and was wondering if this concept could be applied to time as well to allow time travel. Would...

    What happens to gravity in one dimension of space?

    Oh of course, so would it just be x/r^0 so x/1, so x. So then distance wouldn't change anything in 1 dimension

    What happens to gravity in one dimension of space?

    I recently heard that it was found how gravity would behave in different dimensions of space. Apparently, while in our 3 dimensions of space gravity is F= x/r^2, in 4 dimensions it would be F=x/r^3, so it would be weaker, and in 2 dimensions it would be F=x/r so it would be stronger.What it...

    Has relativity been proved wrong?

    Right well it seems I either misunderstood him or he was wrong.

    Has relativity been proved wrong?

    Yes I do think that's what he meant. Specifically he said something along the lines of 'a few years ago Einstein's theory of relativity was shown to not work, it isn't used to explain anything now besides gravity'. This wasn't exactly what he said as i can't remember exactly but it is the...

    Has relativity been proved wrong?

    While explaining how science works in my biology class my biology teacher said that relativity had been proved wrong, except for with gravity, and had been replaced by a new theory. Is this true? and if so what is the new theory and what are its principle ideas?

    How can there be antineutrinos?

    I was wondering how it is possible for there to be anti-neutrinos when antimatter is is identical to matter apart from having the opposite charge. However neutrinos have 0 charge so how can they have anti-neutrinos.

    Any good physics books with the maths as well

    I took a look at the road to reality in the bookshop today. It looked quite complicated are you sure i'll be able to understand it. The mechanical universe courses look good by the way thanks for showing me them.

    Does dark matter have to be one particle

    Whenever physicist talk about dark matter they always seem to be implying that dark matter is one particle. Does this have to be the case? Could there not be many particles that are heavy, slow and with no electric charge that could all be varieties of dark matter.

    What actually happened with the neutrinos

    I know that they didn't actually go faster than than speed of light but I'm not sure what went wrong. I've heard lots of possibilities but i don't know which is right

    Any good physics books with the maths as well

    Thanks these are exactly what i''m looking for

    Any good physics books with the maths as well

    I have read a lot of popular science books which have given me good knowledge about physics but none seem to have the maths. I want to know if there's any you can recommend that have the physics and the maths behind the physics. I'd prefer them to not be to complex but if that's not possible i...

    Greatest physicists of all time alive and dead

    I know this has been done to death already although i couldn't find a proper thread, most seem to degenerate into arguments. I want to know who, in your opinions is 1. the greatest physicist of all time 2. the greatest physicist alive 3. the greatest british physicist 4. the...

    Is chemistry needed for astronomy/astrophysics

    Thanks, i look forward to being in the research community DarkPhysics and jaychristian4, i have already read a brief history of time (not that i got all of it, may want to reread it) and sort of understand the theory of special relativity (though not entirely). If you could direct me to any...
