So with all this talk about quantum computing, I ran into the subject of gravitons while traversing down a rabbit hole.

Over under on when the next breakthrough will come about in this field?

The whole concept of a graviton seems quite elusive.

Aren't gravitons just theoretical. I remember reading somewhere they're based on pretty out there theories.

I don't know a lot about this stuff but I did a quick check of wikipedia and it says there is no quantum field theory for gravity but that string theory predicts it. But I thought there was no real proof of string theory and that it was all still just a theory so I thought maybe thats why he was saying gravitons were elusive because theres no real proof of them.

Good point, you're right. I had it mixed up.

It's not a particle in QFT, but it is a particle that's a product of perturbations to a field (if we're describing gravity as a field) which is pretty similar to how QFT describes fundamental particles.

If you think of gravity as a field I think you should "believe" in gravitons, but probably you shouldn't think about them as point particles.

This is so far outside by knowledge base. I just thought they were based on theories that weren't proven, but you seem to know a lot more about this than I do.

Are you a tachyon?

I forgot how I ran into this article, but I think I found it by reading about the possibility of a quantum internet in the future.

Yeah, it's a bit weighty.

I remember the Gravitron at the carnival, great ride

Which one of the Transformers was Gravitron?
