It starts with the theory of evolution in biology. Just because microevolution happens and both sides agree, it does not lead to macroevolution of change via mutation such as humans from monkeys and birds from dinosaurs. We just do not have the transitional fossil evidence for it. Moreover, there is contradiction in terms of how long-time was calculated using radiometric dating.
One of the latest that I read was that NASA believes that one day we will be able to time travel. We already are able to travel forward in time, but we cannot travel back in time. This is impossible as God has made it so that we will not be able to travel back in time. The Bible does not directly address the idea of time travel because such science fiction did not exist in ancient times. What Scripture indicates is that each person has an appointed time of death (Hebrews 9:27) and that this is known by God before they happen (Jeremiah 1:5, Acts 17:26). This would be possible if God existed in a higher dimension beyond spacetime. He would be able to read what happened to so-and-so as if he were reading a history book. We've already have seen space and time expand until we reach our end. It's just that our time has not caught up to that point yet. As we continue to read the Bible, it often speaks of events occurring according to God's timetable (Genesis 21:1; John 7:8, 1 Timothy 2:6).
This runs counter to the idea of people changing historical events through time travel going back in time.
That said, this is what NASA states:
"General relativity also provides scenarios that could allow travelers to go back in time,
according to NASA. The equations, however, might be difficult to physically achieve.
One possibility could be to go faster than light, which travels at 186,282 miles per second (299,792 kilometers per second) in a vacuum. Einstein's equations, though, show that an object at the speed of light
would have both infinite mass and a length of 0. This appears to be physically impossible, although some scientists have extended his equations and
said it might be done.
A linked possibility, NASA stated, would be to
create "wormholes" between points in space-time. While Einstein's equations provide for them, they would collapse very quickly and would only be suitable for very small particles. Also, scientists haven't actually observed these wormholes yet. Also, the technology needed to create a wormhole is far beyond anything we have today."
