That ironed out wrinkles in its early chaotic self and meant that even now far-flung parts were once in close contact, so could swap heat. However, we cannot neither see, nor infer from their effects on other parts of the universe, any events that are emitted by something which was, at the time of the event, receding from us at a cosmic. In its earliest instants, the universe expanded faster than light ( light’s speed limit only applies to things within the universe). Thanks Universe So, how can galaxies be traveling faster than the speed of light when nothing can travel faster than light Warp speed galaxies come up when I talk about the. We can infer the universe expanding with a speed greater than c based on the redshift of light that has been travelling from a great distance. That seems a naked assault on the laws of thermodynamics.Ĭosmic inflation solves these problems at a stroke. Not only that, but even bits of it far off in different directions as observed from Earth have roughly the same temperature, although in an expanding universe there wouldn’t have been time for heat to pass between them to even things out. The first is that Einstein’s general theory of relativity famously makes mass bend space and time – so you’d expect a universe like ours, containing mass, to be overall curved in some way, either in on itself like a ball (“positive” curvature) or out on itself like a saddle (“negative” curvature). Inflation was invented to explain a couple of features of the universe that are really hard to explain without it. The expansion of the Universe teaches us that the rate that the fabric of space is stretching is greater than the distance we can cover even at light speed the distance between us and them.

Cosmic inflation is a faster-than-light expansion of the universe that spawned many others. So whats happening here The expansion of the Universe means that the further away a galaxy is from us, the faster it will appear to be receding from us.
