Startalk we’re back featuring my interview with the British physicist
interview with the British physicist
interview with the British physicist Brian Cox so I had to bring up the fact
Brian Cox so I had to bring up the fact
Brian Cox so I had to bring up the fact that he and I had like a Twitter
that he and I had like a Twitter
that he and I had like a Twitter argument for the physics of lightsabers
argument for the physics of lightsabers
argument for the physics of lightsabers aha yeah and I just had to bring it up
aha yeah and I just had to bring it up
aha yeah and I just had to bring it up and just open up old wounds yeah right
and just open up old wounds yeah right
and just open up old wounds yeah right let’s find out how it went down I don’t
let’s find out how it went down I don’t
let’s find out how it went down I don’t remember how this happened I think I
remember how this happened I think I
remember how this happened I think I tweeted something about life savers then
tweeted something about life savers then
tweeted something about life savers then you jumped in and then people just
you jumped in and then people just
you jumped in and then people just wanted a fight yeah yeah that was a good
wanted a fight yeah yeah that was a good
wanted a fight yeah yeah that was a good gig fight I think I said if lightsabers
gig fight I think I said if lightsabers
gig fight I think I said if lightsabers are made of white yeah then they could
are made of white yeah then they could
are made of white yeah then they could surely do damage by cutting things but
surely do damage by cutting things but
surely do damage by cutting things but they would not stop one another the way
they would not stop one another the way
they would not stop one another the way two swords would in a swashbuckling
two swords would in a swashbuckling
two swords would in a swashbuckling encounter this that’s all I said there’s
encounter this that’s all I said there’s
encounter this that’s all I said there’s a process that I’ve studied actually
a process that I’ve studied actually
a process that I’ve studied actually photon photon R gamma gamma scattering
photon photon R gamma gamma scattering
photon photon R gamma gamma scattering we college okay so it’s a measured
we college okay so it’s a measured
we college okay so it’s a measured process at particle accelerators so very
process at particle accelerators so very
process at particle accelerators so very high energies very energy collisions
high energies very energy collisions
high energies very energy collisions there’s a probability that photons will
there’s a probability that photons will
there’s a probability that photons will will kick off each other fans off it
will kick off each other fans off it
will kick off each other fans off it rather than just pass through yes so
rather than just pass through yes so
rather than just pass through yes so it’s remarkable the remarkable property
it’s remarkable the remarkable property
it’s remarkable the remarkable property of particle physics so they don’t
of particle physics so they don’t
of particle physics so they don’t interact so I can look at you and all
interact so I can look at you and all
interact so I can look at you and all these other ones that are flying across
these other ones that are flying across
these other ones that are flying across there don’t mess up this view of you but
there don’t mess up this view of you but
there don’t mess up this view of you but actually radio waves and microwaves same
actually radio waves and microwaves same
actually radio waves and microwaves same yeah yeah i phi all over the place
yeah yeah i phi all over the place
yeah yeah i phi all over the place nothing two colliding but actually when
nothing two colliding but actually when
nothing two colliding but actually when you go up high any two high energies
you go up high any two high energies
you go up high any two high energies then the the probability that photons
then the the probability that photons
then the the probability that photons will collide with each other increases
will collide with each other increases
will collide with each other increases and one of the interesting things at
and one of the interesting things at
and one of the interesting things at cosmic ray physics that you might know
cosmic ray physics that you might know
cosmic ray physics that you might know about is that there’s a cut-off yes
about is that there’s a cut-off yes
about is that there’s a cut-off yes we’re donkey car off yeah whether the
we’re donkey car off yeah whether the
we’re donkey car off yeah whether the cosmic rays can be such high energy that
cosmic rays can be such high energy that
cosmic rays can be such high energy that the probability they are bounce off the
the probability they are bounce off the
the probability they are bounce off the photons in the Cosmic Microwave
photons in the Cosmic Microwave
photons in the Cosmic Microwave Background becomes high so so my point
Background becomes high so so my point
Background becomes high so so my point was just a technical one that photons do
was just a technical one that photons do
was just a technical one that photons do have a there’s a probability they’ll
have a there’s a probability they’ll
have a there’s a probability they’ll collide together and if you had this
collide together and if you had this
collide together and if you had this high energy all trying is your
high energy all trying is your
high energy all trying is your lightsaber it would have to be really
lightsaber it would have to be really
lightsaber it would have to be really really high energy lightsaber yeah and
really high energy lightsaber yeah and
really high energy lightsaber yeah and so now this would come into the regime
so now this would come into the regime
so now this would come into the regime that you’re describing and they would
that you’re describing and they would
that you’re describing and they would come in contact and they would you would
come in contact and they would you would
come in contact and they would you would feel this did they interact with each
feel this did they interact with each
feel this did they interact with each other just like just like these things
other just like just like these things
other just like just like these things interact okay what I loved about that
interact okay what I loved about that
interact okay what I loved about that though is you said which I love the fact
though is you said which I love the fact
though is you said which I love the fact that there’s
that there’s
that there’s there’s an audience for that that kind
there’s an audience for that that kind
there’s an audience for that that kind of interaction that we had and it’s case
of interaction that we had and it’s case
of interaction that we had and it’s case really geeky right it’s just you talking
really geeky right it’s just you talking
really geeky right it’s just you talking about lightsabers I had no the physics
about lightsabers I had no the physics
about lightsabers I had no the physics of the like species how much people dick
of the like species how much people dick
of the like species how much people dick out over there
