Community discussions are heating up on gaming forums about the power of Magnetic Accelerator Cannons (MAC) in the Halo series. Recently, people have focused on the specifics of the UNSC Infinityโ€™s cannon, which created a massive crater on Sanghelios. New revelations have emerged that could change perceptions of these powerful weapons.

Fresh Insights on MAC Capabilities

Several commenters revealed impressive calculations regarding the Infinity's MAC. One noted that in Shadows of Reach, the cannon fires a 3,000-ton slug at a remarkable speed of 0.25c (a quarter the speed of light). This has been calculated to yield about 2.1 million megatons, which some described as absurd.

"Infinityโ€™s MAC can propel a 3,000-ton slug at 0.25c. Energy equals 2.1 million megatons."

Another user discussed Orbital MACs, stating their kinetic potential could amount to an energy output of x 10^20 joules, equating to roughly 51.6 billion tons of TNT. This raises vital questions about the authenticity of these reported powers.

Ongoing Physics Debate

The forum discourse leans heavily into the physics of MACs. Users are active in debating the recoil effects generated by such power. "If you fire a railgun, the only mass that can be sent rearwards is the railgun itself," shared a user. Concerns about whether the Infinityโ€™s engines can withstand the recoil remain prominent.

"Firing a MAC could push the Infinity back at 250 m/s."

Some commenters argue for a canon explanation, speculating that some slip-space mechanics could mitigate recoil effects, while others remain skeptical that such forces could be managed without damage to the ship.

Enthusiasm Mixed with Skepticism

The community's reaction is mixedโ€”while fascination with the MAC's destructive potential grows, skepticism about the feasibility of these power levels remains high. As one user candidly put it, "Is it even possible?"

Key Takeaways

  • ๐Ÿ”น Enormous energy output: Infinity's MAC likely generates around 2.1 million megatons.

  • โšก Orbital MAC potential: Calculated energy output stands at 51.6 billion tons of TNT.

  • ๐Ÿ”ธ Physics concerns: Users debate the feasibility of managing recoil in such powerful weaponry.

As the conversation unfolds, many are eager to evaluate how these mechanics work in the Halo universe. Will the community find consensus on the power of MAC cannons, or will doubts continue to linger?
