What is the minimum speed limit in the universe?

In summary, particles with no rest mass, like photons, can only move at the speed of light in all reference frames. Objects with non-zero rest mass can move at any speed less than the speed of light, including zero. The absolute minimum speed limit is not determined by an object's interaction with the higgs field, but rather its rest mass.

I have a question :x

Technically, particles, like photons, which don't interact with the higgs field travel at the speed of light.

wouldn't the absolute minimum speed limit be something that interacts infinitely with the higgs field?

No. Particles with no rest mass are constrained to move at the speed of light in all reference frames but objects with non-zero rest mass can move at any speed less than the speed of light, including zero.

An object does not have to be infinitely massive to be stationary with respect to an inertial frame - it only needs to have non-zero rest mass.

All things (other than those moving at c) move at a relative speed, defined by a reference frame. Therefore the speed can be anything from 0 up < c.

What is considered the minimum speed in the universe?

The minimum speed in the universe is the speed of light, which is approximately 299,792,458 meters per second. This is the fastest speed that is physically possible for anything with mass to travel.

Why is the speed of light considered the minimum speed in the universe?

According to Einstein's theory of relativity, the speed of light is a fundamental constant in the universe and cannot be exceeded by any object with mass. As an object approaches the speed of light, its mass increases infinitely and it would require an infinite amount of energy to accelerate it further.

Can anything travel faster than the speed of light?

No, according to the laws of physics, nothing can travel faster than the speed of light. Even if we were able to somehow overcome the limitations of mass and energy, the concept of time itself would break down at speeds faster than light.

What are some examples of objects that travel at the minimum speed in the universe?

Some examples of objects that travel at the speed of light include photons (particles of light), as well as other massless particles such as gluons and gravitons. However, it is important to note that these particles do not have mass and therefore are not subject to the same limitations as objects with mass.

Is it possible for the speed of light to change?

According to our current understanding of physics, the speed of light is a constant that does not change. However, some theories propose that the speed of light may have been different in the early stages of the universe, and it is an area of ongoing research and debate in the scientific community.
