Traveling through time may be theoretically possible, but it is beyond our present technological capabilities.
"One of the great challenges in this world is knowing enough about a subject to think you're right but not enough about the subject to know you're wrong." - Neil deGrasse Tyson
"The future depends on what we do in the present" by Ghandi is perhaps one of the most famous quotes there are regarding living in the moment. However, reality challenges the concept of the present in ways physicists have only recently begun to understand.

If you listen to the media hype these days you would believe the frequency of hurricanes hitting the United States has been dramatically increasing due to climate change. However, if you look at the facts the number of hurricanes hitting the United States has not been increasing at all.
Fusion is the process in which light elements fuse together to form heavier elements in the cores of stars. Hydrogens (the lightest element) smash together to form helium (the second lightest element), and the process continues all the way up until iron can be formed. This ends up releasing a lot of energy, which is how a star is fueled. But how does this process actually go down?
Climate change is real. Or at least it should become more real to people. For a while my tomatoes were growing just fine. Then they died from the hotter weather. I'm trying to keep up with the task of drilling holes in my drawers where I plan on housing my plants. I also have a plastic container that holds my zucchini, which has flowers, although this might die too. Climate change is happening. This is a fact, the weather is changing, Antarctica the continent, and the Arctic the land mass are melting. Someday we will be able to settle either. Maybe this is necessary as the population on this planet keeps growing.
A Rather Lengthy but Important Foreword: I am not writing this to dunk on Flat Earthers or to celebrate the death of someone who was (debatably) part of their movement. This is not blaming the victim for his own death. This is bigger than those petty concerns.
