Thank you for streaming and for sticking with us! Here is our final live broadcast for our Free SPM Seminar September 2014 with Ms. Nicole dishing out some tips and tricks for your Physics…
Can you tell me If I create uranium with very little energy and fire a
proton into it with very little energy will it still give the same amount
of energy as it normally does? (proton fired so it doesn’t make chain
reaction)
Gravity is not a force it is a property of space.
(1) In 300-400 years, we will be amazed at how rudimentary our
understanding of space-time and gravity was in 2015.
(2) So, “the universe” is expanding into.. what..?
the ven diagram of what is and what is observed would be a point on a
circle
Can someone explain to me about gravitons?What does he mean when he say
that graviration is carried by gravitons?Is that mean that gravitons are a
way to identify the partical they are encountering just like electrons send
photons to identify other electrons?Also is that mean that dark matter
could just be the effect of gravitons that basiclly enchance the
gravitational attraction between bodies so that galaxies could be formed?
Why people give away their basic common sense to such nonsense as this,
remains to me the greatest mystery of all. How can anyone possibly know how
gravity works? … Oh yeah, sorry I forgot. Give away your own commonsense
and get some con artist to make up a THEORY.That’ll explain it. DONE

I have a question if anyone knows could answer: I have a rifle, and I fire
it straight into the air. The bullet will travel at immense speed up, up,
up until eventually, the force of gravity will overcome it’s velocity and
the bullet, for a minor second, will pause mid air… Then the bullet will
begin to descend back down to earth. It will accelerate at a rate of 9.8
m/s^2, down, down, down until eventually it will reach terminal velocity.
My QUESTION is: is energy truly conserved; does the initial discharge
velocity/power of the bullet = the terminal velocity/power of the bullet
when it strikes the ground? I know that dropping a coin from a tall enough
sky scraper that it could damage/penetrate someone’s skull is a myth, but
at the same time it is also illegal and dangerous to discharge a gun into
the air (which is why service funerals use blanks). If the bullet pauses at
the top, how is it any different than if I were to simply DROP the same
bullet, from say a plane, at the same height? I’ve been pondering this for
a while…
Is it possible to walk on walls and ceilings? Callum 7 years old. ps your
channel is awesome :D
How can gravitons be unobservable, they just haven’t been found yet or am I
missing something?
This man has got it wrong!
Einstein’s general theory of relativity has proven many times over that
gravity does not exist and that gravitation is caused by the distortion of
space-time caused by the uneven distribution of particles.
Anyone believing that gravitation is caused by a force (gravity) will
struggle in this field.
Anyone looking for the hypothetical force carrier, the graviton, will be
looking until the end of time because neither gravitation or gravity are
forces.
Gravity doesn’t come from mass or energy. It comes from Energy + Momentum,
which both matter and light has.
How does 2 dimensional spacetime encompass a 3 dimensional universe?
I was at a Christian friend’s house, and her mom said something about “god
making everyone unique” and then since she knows I am an evolutionist, she
said “we don’t believe in the theory of relativity in this house” I laughed
so hard I couldn’t even explain to her how ridiculously mixed up she was
without bursting out laughing again.
So the gravity predicted the existence of my anus. great. It would’ve been
easier to ask ^^
What about dark matter?
The Misunderstanding of Gravity: Part One

Gravity isn’t conveyed by special particles, such as “gravitons”, but by a
combination of inertia and the movement of spacetime itself.
The distortion of spacetime caused by a massive object is caused by the
matter in that object possibly converting the spatial component of the
planck lengths of the spacetime into planck times, resulting in “less
space” close to a massive object than you would otherwise expect.
Why is all of spacetime not sucked away into objects with mass? The dark
energy which causes the “expansion” of the universe could be inserting
extra planck lengths of spacetime at a greater rate than all the mass of
the universe can absorb it, including that of dark matter.
In a nutshell, gravity itself isn’t a force, but exerts a force on objects
with mass and spacetime behaves much like a fluid in its spatial form. This
is why the acceleration due to gravity appears to follow an inverse-square
law, at least in classical gravity.
Since particle accelerators have been brought up in this thread in relation
to the attempt to observe gravatons keep in mind that the only known and
functional version of particle accelerators are on or slightly below the
surface of the earth. Meaning that they are sitting approximately a
distance equal to the radius of the earth away from a massive distortion in
space time. I.E. the results of earth’s gravitational field. You
therefore can not expect to observe the same set of results as would happen
in a truly static environment.
If gravity is the curving of space caused by a large mass, where do
gravitons come in? The concept of gravitons seems redundant to me. What do
they do that adds anything to our understanding of how gravity works?
why the hell do you talk so fast,you are not teaching you are just showing
off that you know all of stuff about physics.
Have u heard the theory that Gravity is the weakest of the 4 forces bc it
may interact with parallel dimensions, and might be able to prove the
possibly of multiple dimension theory? Feel free to post replies about
what you think on both sides of the argument.
If my understanding of this (G= M1*M2/D^2) is accurate, Jupiter has the
strongest gravitational pull with the sun, followed surprisingly by Venus,
then Saturn, and then Earth. Correct?
I thought the gravity particle was boson, so what’s the difference with
graviton??
Is it bad that I am already 12 and can’t do physics about the strong force?
