Good morning all,

According to the equation of relativity for a macroscopic object to go at the speed of light it needs infinite energy (E = mc ^ 2 / root (1-v ^ 2 / c ^ 2) with E the energy and c the speed of light and v the speed of the object, if v = c we have E tends to infinity).

However, this answer is purely mathematical or infinity exists, but in physics infinity does not exist and any magnitude experiences saturation.

Mathematics does not manage time, and a number does not exist in reality nor infinity which is a sum of numbers for example 1 + 2 + 3 + 4 .. = infinity.

In physics manages time and any system has a lifetime and finite energy for example 1 + 2 + 3 + 4 .. = - 1/12 physically, and this equality is verified with experimental physics with the casimir effect and mathematically refute.

Infinity does not exist anywhere in our universe everything has a finite life and energy even our whole universe.

For example at the start of the universe there are indications that maybe matter could have gone faster than light, and there is a contradiction with the theory of relativity so there are theories which assume that the speed of light has varied, and that the theory of relativity works but with a varying speed of light, or we assume another theory with an inflation phase or the theory of relativity does not.

What if it's just a matter of energy and the energy of the beginning of the universe has all just hit a physical threshold where it goes faster than the speed of light.

Even the theories of quantum gravity predict a variation of the speed of light according to the energy level and also other theories alternative to the theory of inflation.

So with his theories if normally have reached an energy Emax the speed of light can vary up to 10 ^ 60 c and the new speed of the object v can exceed the speed of c = 300,000 km / s up to v10 ^ 60 c according to observations of the past of the universe.

What if there is an energy that can be applied to a macroscopic object even with a short time to get it to go at the speed of light or higher and that depends on the property of the object.

Maybe we have to formulate the problem in the form of a series that mathematically gives infinity for example 1 + 2 + 3 + 4 .. = infinity because I would need an infinite energy, but physically will give an energy finite by example 1 + 2 + 3 + 4 + .. = - 1/12 to apply to an object to go faster than light.
