If you are someone who keeps up with science and universe-related news, then the rapid expansion of the universe is nothing new. Our universe is constantly expanding every second of every day and is concluded by the increase in distance from two gravitationally bound parts of the observable universe in a given time.
This expansion is considered an intrinsic expansion, meaning that the scale of space itself will change in this given time. When this is occurring, the objects that are in space also move as well.
Unfortunately, some scientists are worried that our universe is expanding much too fast for our own good. Others think that we are too slow in thinking and that the timeframe and distance we thought the universe would expand in, is wrong.
This causes many debates about the expansion of space and causes theorists to think outside of the box. Here is what we know so far.
