Did the Big Bang violate the speed of light?
The Big Bang itself expanded much faster than the speed of light. But this only means that “nothing can go faster than light.” Since nothing is just empty space or vacuum, it can expand faster than light speed since no material object is breaking the light barrier.
Did Einstein believe the universe was expanding according to the big bang theory?
There are different theories for how the universe began. The big-bang theory says that it began when a tiny but dense mass of energy exploded. And it says that the universe has been expanding ever since. Einstein himself did not come up with the theory.
Did the universe expand faster than light during the Big Bang?
In the first millionths of a second of the Big Bang did the universe not expand faster than the speed of light? As a spoiler: no, it didn’t expand faster than light then, nor at any other time, nor will it ever do so. Our Universe, as we see it today, has been around for 13.8 billion years since the hot Big Bang.
Does the expanding universe break the speed of light?
Universal expansion The expansion of the universe causes distant galaxies to recede from us faster than the speed of light, if proper distance and cosmological time are used to calculate the speeds of these galaxies.
Why doesn’t inflation violate the speed of light?
In an inflationary Universe, any two particles, beyond a tiny fraction of a second, will see the other one recede from them at speeds appearing to be faster-than-light. But the reason for this isn’t because the particles themselves are moving, but rather because the space between them is expanding.
How was the Big Bang theory developed?
A Belgian priest named Georges Lemaître first suggested the big bang theory in the 1920s, when he theorized that the universe began from a single primordial atom. It’s also thought that the extremely close quarters allowed the universe’s very first particles to mix, mingle, and settle into roughly the same temperature.
What did Albert Einstein say about the Big Bang theory?
Albert Einstein once proposed an alternative to the Big Bang theory, arguing that rather than a single explosive event, the universe expanded steadily and eternally.
Did the early universe expand faster than the speed of light?
But no object is actually moving through the Universe faster than the speed of light. The Universe is expanding, but the expansion doesn’t have a speed; it has a speed-per-unit-distance, which is equivalent to a frequency, or an inverse time.

Did the Big Bang expand faster than the speed of light?
Some sources indicate that the big bang caused an expansion which traveled faster than the speed of light. How can this be? You ask a good question, one whose answer lies in the subtle difference between expansion that is faster than the speed of light and the propagation of information that is faster than the speed of light.
What is the relationship between the speed of light and expansion?
The expansion of the Universe is a “growth” of the spacetime itself; this spacetime may move faster than the speed of light relative to some other location, as long as the two locations can’t communicate with each other (or, in terms of light rays, these two parts of the Universe can’t see each other).
What happens to the speed of light in an inflationary universe?
If two particles are created very close to one another during this inflationary state, they still have to obey the laws of special relativity: they can only move relative to one another at speeds less than (or equal to, if they’re massless) the speed of light. But the space between them is free to expand at whatever rate the Universe dictates.
How did the universe change after the Big Bang?
For the first few thousand years after the Big Bang, radiation dominated. For billions of years after that, matter dominated. And today, it’s dark energy. But before the Big Bang, space expanded at an exponential, enormous rate, which stretched the Universe flat and gave it uniform properties everywhere.
