Tahukah anda jika anda melihat bintang di langit pada waktu malam, anda actually sedang looking to the past, not the present time. Ini adalah thread tentang bintang.
Aku pernah terbaca dekat Quora someone cerita that some scientist claims that if there is an alien 65 million light years away from Earth, if they see Earth using a powerful telescope right now, then they would see dinosaurs instead of humans.
How is that possible?
Before that hang pa kena tahu a few facts about light dulu:
1) Light is the reason why an object is visible. Means that light is the reason kenapa kita boleh lihat object surrounding kita.
Light ni dia contain photons. When photons hit an object, atoms from that object will absorb the light wave and release certain light wave with certain wavelength that produce colour so mata kita boleh interpret.

Dalam bahasa mudah ialah light that hit an object masuk mata kita, then retina dalam mata kita akan interpret that light. That is how we see in simple word.

2) Light is the fastest known entity in our universe which is bersamaan dengan 299,792,458 m/s.
Okay, let's move on.
So tahu kah anda bahawa jarak Bumi ke Bulan berrsamaan dengan 384,400 km, tetapi untuk cahaya nak travel dari Bumi ke Bulan hanya mengambil masa 1.3 light second. Back to the facts about "Light is the reason why an object is visible. Means that light is the reason kenapa kita boleh lihat object surrounding kita." So in order untuk kita nampak Bulan mesti la kena ada cahaya, kan? So kan cahaya dari Bulan tu take 1.3 second nak sampai dari Bulan ke Bumi, maksudnya by the time cahaya dari Bulan tu masuk mata kita, 1.3 second telah berlalu. So apa yang kita lihat tu bukan lah Bulan yang sekarang, tetapi Bulan pada 1.3 saat yang lalu.
