Question

Is it possible to travel back in time?

Answer 1

$\fbox\red{\:ANSWER :- }$

⇒Real-life time travel occurs through time dilation, a property of Einstein's special relativity. Einstein was the first to realize that time is not constant, as previously believed, but instead slows down as you move faster through space.

Answer 2

the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
