How big the space is ?

The size of space is difficult to comprehend. The observable universe, which is the part of the universe that we can see, is estimated to be about 93 billion light-years in diameter. This means that it would take light 93 billion years to travel from one side of the observable universe to the other.

However, the actual size of the universe may be much larger than the observable universe. This is because the universe is expanding, and the rate of expansion is accelerating. This means that the distance between two galaxies is increasing over time.

As a result, it is impossible to say for sure how big the universe is. However, we can estimate that the universe is at least 250 times larger than the observable universe, or about 7 trillion light-years across.

To put this into perspective, the Milky Way galaxy is about 100,000 light-years in diameter. So, the universe is at least 70 billion times larger than the Milky Way galaxy.

It is truly a humbling thought to consider the vastness of the universe. We are just a tiny speck in an immense and ever-expanding cosmos.
