If the universe is running down like a clock, the clock must have been wound up at a date which we could name if we knew it. The world, if it is to have an end in time, must have had a beginning in time.
Sentiment: NEGATIVE
Virtually every scientist now concedes that universe and time itself had beginning. So, whatever begins to exist has a cause. The universe began to exist. Therefore, the universe must have had a cause.
And time itself? Time was a never-ending medium that stretched into the future and the past - except there was no future and no past, but an infinite number of brackets, extending either way, each bracket enclosing its single phase of the Universe.
It now appears that the way the universe began can indeed be determined, using imaginary time.
This fact immediately suggested a singular event - that at some time in the distant past the universe began expanding from an extremely small size. To many people this inference was loaded with overtones of a supernatural event - the creation, the beginning of the universe.
There will come a time when you believe everything is finished. Yet that will be the beginning.
Even Hubble hasn't found yet the end of this universe, and we don't know that it has any end.
In moments of transcendence, when time stands still, your biological clock will stop. The spirit is that domain of our awareness where there is no time.
If we knew exactly the laws of nature and the situation of the universe at the initial moment, we could predict exactly the situation of the same universe at a succeeding moment.
There is no rational reason to doubt that the universe has existed indefinitely, for an infinite time. It is only myth that attempts to say how the universe came to be, either four thousand or twenty billion years ago.
Time is still the great mystery to us. It is no more than a concept; we don't know if it even exists.
