While we have very limited information about the first split seconds of our universe’s existence, but before we get to the new information, let’s talk briefly about what we do know. We know the universe had a beginning. Our evidence of this comes from both scientific and philosophical research. We know that logically an infinite regression is metaphysically impossible because inverse operations are off limits in transfinite arithmetic.
We simply cannot do subtraction or division when it comes to infinity. If you had an infinite number of marbles labeled 1 on to infinity, and took away all the even numbers, you are subtracting an infinite quantity from an infinite quantity and are left with an infinite quantity. However, if you took away all marbles greater than 3, you are taking away an infinite quantity from an infinite quantity and are left with 3. Subtracting infinity from infinity leads to conflicting results and logical absurdities and this is why it is off limits to use subtraction and division in quantities of infinity.
But what about the scientific evidence? We have red shift, gravitational waves, the second law of thermodynamics (implying entropy), the Borde-Guth-Vilenkin theorem (linked below is their paper from the Cornell University Library), the theory of relativity, and so much more evidence that the universe did have a cosmic beginning around 13.7 billion years ago.

On to the new information! When the physical universe as we know it sprung into existence from a quantum vacuum (the origin of which has yet to be explained), magnetic fields were created. Astrophysicists have now been able to calculate these magnetic fields and even have a three dimensional representation of what they should look like. These numbers were crunched by the Max Planck Institute for Astrophysics in Garching and a team in which they led.
This is insanely important because it affects the way galaxies interact and expand in the universe. One interesting note to take from the diagram in the attached link is that the magnetic field is not uniform or homogenous.
Scientists were able to make these calculations by taking a plasma-physical effect called the Harrison Effect into account. The idea astrophysicists have is that immense amounts of friction must have created the magnetic fields we observe today. For more information on this, check out the link below. Something really interesting to note is that like Hawking Radiation and many other spectacular scientific discoveries, we cannot observe this- or at least not yet. Who knows what will be discovered tomorrow?
