Finalgear, are you space?
Yes son, we are space.

Wow. I just don't know where to begin. I will grant them that the Earth is growing*, but not like that.
* Plant matters grows and dies and turns into more dirt which helps more plants grow. And since much of the energy is from the sun, more matter is grown than consumed so there is a net gain.

The planet earth does not "grow" in the way the video shows. But it does grow due to the plant matter as I mentioned above. Don't believe me, explain why archaeologists have to dig down through layers of dirt that they can identify to get to fossils.

Not sure if trolling? If not:
Sorry to break it to you but matter cannot form out of nowhere. It can be reorganized but not be created (not under the conditions here on earth anyway). A plant draws the material it uses from the earth and releases it again when it rots - no mass gets added. All the material that composes the dirt that covers the dinosaurs was there before it was dirt - just in another form, like rock or CO2.
Using the Hubble Space Telescope, astronomers are witnessing the unprecedented transition of a supernova to a supernova remnant, where light from an exploding star in a neighboring galaxy, the Large Magellanic Cloud, reached Earth in February 1987. Named Supernova 1987A, it was the closest supernova explosion witnessed in almost 400 years. The supernova's close proximity to Earth allows astronomers to study it in detail as it evolves. Now, the supernova debris, which has faded over the years, is brightening. This means that a different power source has begun to light the debris. The debris of SN 1987A is beginning to impact the surrounding ring, creating powerful shock waves that generate X-rays observed with NASA's Chandra X-ray Observatory. Those X-rays are illuminating the supernova debris and shock heating is making it glow in visible light. Since its launch in 1990, the Hubble telescope has provided a continuous record of the changes in SN 198
