Subject: RE: Is the universe infinitely large or finite in size?
Not a bad start. I want to add a few things including the concept of inflation. Immediately after the big bang for a period of time that lasting less than a fraction of a second a process of inflation occurred that expanded the universe from, effectively nothing to approximately 90% of its size today. This inflation was caused by the incredible enthalpy (energy) present during the initial condition.
So over the past 13.7 billion years since this event the universe has expanded, at an accelerating rate, but is only about 10% bigger than one second after the big bang. This would indicate a radius of 120-130 Billion light years.
The argument for all this is derived from Einstein’s General Relativity and the observation that matter distorts space.
The concept of 11 dimensions is not that tough to picture if you imagine that 7 of them are curled up so tightly that they have been unobserved and ignored until the last 25 years. Only specialized mathematics techniques indicate that they are there at this point. These dimensions are very important as they form the fabric of space and enable almost all observable phenomena like:
The establishment of constant values for fundamental particle energy and masses.
The wave/particle nature of light is caused by its interaction with the fabric of space. This interaction occurs on a scale less than the Plank length (lp) transferring spin and vibration (EM spectrum), while regulating its velocity (c).
Racehorse, asking questions about where it all came from and where it’s all headed has given Physicist’s a greater insight into the “engine” that is driving nature now. If you think that has no practical application or minimal impact on our lives here on earth re-read the two examples described above. We are on the verge of huge discoveries in this field.
