Marvel in the Sky: Halley’s Comet

Halley's Comet

Halley’s Comet appears every 75 to 76 years.  It has had a recorded appearance since at least 240 BC. The last time Halley’s Comet crossed our planet’s sky was in 1986. Sometimes referred to as Comet Halley, it was formed 4.5 billion years ago.

Halley’s Comet was named after Edmund Halley who predicted the next time it would be seen. After his prediction came true, the comet was named after him. Halley’s Comet is about 6 miles across in length and is composed of rock, dust, and ice. The next time that Haley’s Comet will be visible to us is in the year 2061.

    That is an amazing comet, but I doubt that the comet was formed over 4.5 billion years ago, or millions of years ago. The truth is that comets disintegrate and have an average life span of around 10,000 to about 100,000 years. In fact it should melt a little earlier because of the Sun’s rays melting it faster. This gives the big bang hypothesis a huge problem. How can there still be so many comets around, they should have all disappeared by now. Maybe there was never really a Big Bang.
