3:20- that should say planck

In this video examine how we can potentially discover the existence of Gravitons with current technology such as what is found at LIGO and some potential pitfalls that these methods have.

Just one thing. I absolutely love that you included “Atoms do not look like this” in the corner. Everyone doing orbitals know how frustrating it is seeing the Bohr model, even though it is actually good to visualize the Leyman to Bracket photon emission and the photoelectric effect

[petersuvara]

I thought according to General Relativity, Gravity is not a force, it is a side effect of bending spacetime.

[willemvandebeek]

Isn't gravity something like sound and magnetism? I mean "phonons" and "magnetons" do not exist either.
So isn't gravity the "sound" that mass makes, like magnetism is the "sound" electricity makes?

I am going to watch previous 2 videos about gravitons right now

I really don’t see how Gravitons can actually exist. 
We know that gravity propagates at the speed of light and we also know that two opposing gravitational fields cancel each other out.

So if the force carrier of gravity was in fact the graviton, then based on our current understanding of physics, the graviton must be massless and one graviton would influence another.

Yet, when we consider black holes. We know that the gravity, whilst it does propagate AT the speed of light, cannot be carried by a force carrier thats motion is restricted to the speed of light.

How do we know the area of a graviton without proving gravitons exist?

[mohit]

Here before you get million subs .. awesome content

[zitriphyer]

Why don't we not try to detect a single graviton, but instead a cluster of them? All we really want to know how to do is manipulate it, so we just need to know how to detect a large group of them, then how to manipulate it.

I love how new science is just old science with new understanding and technology. It shows how smart some humans have been, but does kind of reflect how hard it is to get people to believe science

[waffle]

You could do a great angry video game nerd voice.

[JFFXO]

it’s sad that only a small amount of people are on the same timeline as me this is a checkpoint we all spread into infinite decisions from here🧿you made it this far amazing

[staceymyers]

Might I suggest you consider phrasing the existence of gravitons as a maybe? It seems entirely possible there is no graviton and gravity is actually an illusion caused by the curvature of spacetime.

[cinnavanilla]

If the main issue with detecting Gravitons is that their force is very weak, maybe the problem here is that we’re measuring them on Earth. In the future, when space travel is more common, we should try to measure them on planets with much greater gravitational force, like Jupiter for example. I don’t know, just a thought I guess.

[frankmightygamer]

So if the scientists know the frequency why don't they destroy the gravitons in that area if they are successful destroyed won't the area have anti gravity also I like your intro

[தமிழ்படங்கள்-ழட]

If we find them can we manipulate them and harness energy from them ?

[kidstv]

Good summary of Dyson's "Is graviton detectable?" lecture

[sinebar]

Maybe when a star collapses into a black hole it actually becomes a super massive graviton or some other kind of super massive particle. I mean if you think about a black hole it kind of resembles a particle. It's very very small. It can have electric charge or no charge and it can have angular momentum. Kind of sounds like a particle. So in fact maybe a black hole IS a graviton.

[ravalentmarshal]

Can I request video about explaining what is quasar, magnetar, and pulsar?

[StuMas]

Call me cynical but, Gravitons sound theoretically absurd to me for, it implies a possible disconnect between mass and gravity. Is that not the case?

[patpat]

One question : since we can detect gravitational waves, cant we make them interfere and thus anihilate as for light ?
Thanks
