Massless particles that can generate forces?

AI Thread Summary
The discussion revolves around the conceptualization of a futuristic device in a science fiction video game that creates energy cubes with unique properties. These cubes simulate gravity, can interact with real objects, and are visually observable, yet they lack a center of gravity and do not degrade over time. The cubes are described as "heavy," implying they cannot be easily lifted but can exert significant force. Suggestions for plausible explanations include the idea of using materials with negative mass, which could theoretically allow for properties such as floating or not adhering to traditional gravitational behavior. The conversation touches on the implications of net mass equaling zero, which could enable travel at the speed of light without violating known physical laws. Additionally, there is a question about the meaning of "simulating gravity," indicating a need for clarity on how these cubes would function within the game's physics.

Hello,

I am a game developer working on a science fiction video game. The game is intended to be vaguely scientifically plausible and I'd love some advice from someone with a greater knowledge of physics than me!

In the game, you have a futuristic device that creates cubes of "energy". You can stand on these energy cubes, they simulate gravity, they can hit other real objects and move them, and can land on surfaces like the ground and such. They move with the Earth's rotation.

However - they don't exactly behave like a cube made of matter. They don't have a center of gravity (if you had one stacked on top of another such that the center of the upper one had nothing underneath it, it would not rotate and fall down). They don't get damaged or corroded or anything.

I also imagine them being "heavy". You could not pick it up, but perhaps it would move with sufficient force (say, a forklift or something)

... and of course you can see them. So there are photons all up in there too. Like a "force field" I suppose!

If you wanted to give a semi-plausible explanation for this, what would you say? Are there any theoretical particles that have properties like this?

Thanks for any help.

No not really! Unless a ring magnet is something other than one of those things you find inside a speaker
 
consider trying rocky and Bullwinkles magic mysterious material upsydaisium. A material with negative mass that falls up.

If you combine a device with negative and positive mass materials such that net mass is 0 like your cube.

BTW Net mass 0 can travel at c without violating comrade einstein rules
 
What do you mean by "they simulate gravity"?
 
I'm currently writing a novel in which my main character was a victim of experimentation (cliche, I know) but has no memory of it. In the experimentation, technology was implanted in the character's body, allowing an AI algorithm to run off of the character and fuse it's psychological aspects with an actual human's. I'm not super knowledgeable in science such as this, and I'm sure doing this would be incredibly hard, if not impossible, to do. So for the sake of keeping the peace, let's just...
This is a question for people who know about astrophysics. It's been said that the habitable zones around red dwarf stars are so close to those stars that any planets in the zones would be tidally locked to the stars in question. With one side roasting and another side freezing almost forever, those planets wouldn't be hospitable to life. a) Could there be forms of life--whole ecologies--that first evolve in the planet's twilight zone and then extend their habitat by burrowing...
I know this topic is extremely contraversial and debated, but I'm writing a book where an AI attempts to become as human as possible. Would it, eventually, especially in the far future, be possible for an AI to gain a conscious? To be clear, my definition of a consciousness being the ability to possess self-created morals, thoughts, and views, AKA a whole personality. And if this is possible (and let's just say it is for this question), about how long may it take for something to happen...
