SUMMARY

The discussion centers on the concept of mass in relation to the expansion of the universe. Participants clarify that mass does not inherently increase due to cosmic expansion; rather, it remains constant unless energy is added to a system, as illustrated by Einstein's equation E = mc². The humorous reference to personal weight gain after Thanksgiving dinner serves to emphasize the distinction between mass and energy. Overall, the consensus is that mass is a conserved quantity in the absence of external energy inputs.

PREREQUISITES
  • Understanding of Einstein's equation E = mc²
  • Basic knowledge of mass-energy equivalence
  • Familiarity with concepts of cosmic expansion
  • Awareness of conservation laws in physics
NEXT STEPS
  • Research the implications of Einstein's theory of relativity on mass and energy
  • Explore the concept of cosmic expansion and its effects on physical laws
  • Study the conservation of mass and energy in closed systems
  • Investigate the relationship between mass, energy, and momentum in physics
USEFUL FOR

Students of physics, educators, and anyone interested in understanding the principles of mass, energy, and the universe's expansion.

I heard something that your mass increases due to expansion of the universe or something? Is this true?

Also, is the universes momentum constant?

My mass increased after Thanksgiving dinner, so no my mass is not constant.

Perhaps you should refine your question a bit.

LMAO, your right. Thats my fault. I mean if you don't add anything to it, will it increase by itself?

Well if you don't add some form of energy (such as Turkey or Stuffing) to it, no your mass will not increase all by itself.

See equation: E = m * c2
